Mining Filter Plates: Repair vs. Replace

Should You Repair or Replace Your Mining Filter Plates?

A functioning filter press is absolutely essential for the mining of metallic ores and precious metals. If even one component, like the filter plates, isn’t working correctly, contaminants can be allowed to enter our supply of fresh, clean water and soil. These contaminants may include everything from heavy metals and acids to salt and oils, all of which can lead to serious environmental and health consequences. So if an issue does arise with the filter plates, it’s important to address it quickly and correctly.

M.W. Watermark™ offers a wide range of knowledge and expertise on filter press technology and is one of the leading suppliers of filter press plates and other parts. Here are some tips on how to decide whether you should repair or replace your mining filter plates.

M.W. Watermark offers filter plate repair services or replacement for mining filter presses.

When to Repair

Because filter plates have to filter substantial amounts of mining slurry, they’re prone to breakage or malfunction. That’s why they need to be inspected and cleaned on a regular basis. Cleaning, in particular, is vital to keeping the filter press in peak condition. Plates have to be thoroughly cleaned after scraping to prevent sludge from lingering in the gasket sealing surfaces. Dirty plates decrease performance and can also cause the sidebars of the filter press to corrode.

If you’re experiencing issues with your filter plates, they may just need to be power washed. However, there could be a broken or worn component that needs to be repaired, like the filter cloth or gasket. If that’s the case, M.W. Watermark can help you troubleshoot and make basic repairs on-site. Check out our free online video tutorials and stock up on any maintenance or installation supplies you may need.

M.W. Watermark Offers Filter Plate Repair Services

However, since mining applications are particularly tough on filter plates, some of the plates in the press may eventually need to be serviced. This is where M.W. Watermark’s filter plate repair services can help you save money before replacement becomes necessary. Our repair services include cleaning, plastic welding, sandblasting and plate packing (replacing rubber gasketing / packing seals / collars). We can even replace the handles on your plates.

When to Replace

Filter plates with significant issues or those that are simply worn out may need to be replaced. It helps to keep spare plates on hand for incidents like this in order to avert serious downtime. But if you do need to order new plates, M.W. Watermark can supply filter plates for many makes and models of filter presses, including Metso®, Larox®, Ishigaki® and IPM® as well as others.

Best Practices for Dealing with Swarf Slurry in Glass Fabrication

Swarf slurry, the semi-liquid mixture left behind after the glass fabrication process, presents challenges for shops. It can’t simply be dumped due to strict EPA regulations, nor can it be reused until it’s been properly treated.

After many years of solid-liquid separation experience across multiple industries, including glass fabrication, M.W. Watermark™ has developed a system for dealing with glass wastewater that benefits shops in more ways than one.

Challenges with Swarf Slurry

There are several individual processes involved in glass fabrication that generate wastewater. These often include:

  • CNC Work Centers
  • Waterjets
  • Edgers / Grinders
  • Beveling and Mitering
  • Drilling, Sanding and Milling

This wastewater is made up of water and fine suspended particles. The good news is that the water can be reintroduced back into the fabrication system. However, it must first undergo a filtration process to separate the water from the solids.

This is because these contaminants can actually wreak havoc on the shop’s equipment, causing damage and clogged pipes. As a result, shops may be faced with significant repairs and downtime. So, the question remains of how to best filter and treat the slurry.

M.W. Watermark Manufactures Filter Presses for Glass Fabrication Wastewater Recycling; Swarf Slurry Water Treatment

Glass Wastewater Solutions

M.W. Watermark has developed a glass wastewater treatment recycling system to deal with the swarf slurry. Here’s a breakdown of how it works.

  1. Wastewater is pumped from sumps to a swarf slurry holding tank.
  2. Slurry pump moves it from the tank to a filter press.
  3. Filter press filters the water, leaving behind a filter cake.
  4. Clean water moves to a filtered water tank.
  5. Clean water is pumped back into the glass fabrication system for use in grinding, beveling, mitering, drilling, sanding and milling.

Recycling the slurry is ideal because it helps cut costs on water and sewer bills and offers a more convenient solution for glass fabrication shops. Plus, it helps conserve the earth’s water supply in compliance with government regulations.

Water Filtration and Reuse in the Concrete Industry

Over the past 15 years, M.W. Watermark™ has seen the need for concrete wastewater recycling technologies grow firsthand. As environmental regulations and overheard costs continue to place pressure on ready-mix concrete companies, more and more of them consider wastewater management not just a priority, but a necessity. From cleaning the inside of a concrete truck’s drum to concrete coring, floor polishing, cutting, grinding and more, wastewater treatment equipment, including filter presses, are now being used for numerous applications within the industry.

Wastewater Continues to Be an Ongoing Challenge

High volumes of water are required to keep the concrete industry running. In fact, ready-mix plants produce thousands of gallons of wastewater every single day from rinsing the equipment that’s used to mix, transport and place concrete. However, this concrete washout water is toxic to the environment, so much so that the Clean Water Act, among other regulations, places strict limitations on how washout is collected, contained, treated and disposed of. As a result, wastewater is an ongoing and costly problem for the industry. But thanks to advanced filter press technology, companies are now able to expand their efforts while protecting the environment and saving money.

Slurry Water Filtration Recovery and Reuse

A filter press makes it easy to separate solids from water. In the concrete industry, this means a facility can recycle and reuse the clean filtrate over and over, instead of having to waste gallons of fresh water every day. It also helps keep contaminated water out of the sewers, ground, lakes and rivers in order to comply with local and federal standards.

With the growing need to reuse water in the concrete industry, filter presses can aid in the following applications:

  • Ready-mix reclaim systems
  • Ready-mix and precast concrete washout pits
  • Block grinding
  • Concrete cutting and grinding
  • And more…

How Filtration Equipment Benefits the Mining Industry

To deliver the raw materials many industries depend on, mining companies must generate a substantial volume of wastewater that has the potential to contaminate our soil and water. Fortunately, through the help of filtration equipment, like that produced by M.W. Watermark™, the mining industry has been able to adopt more eco-friendly practices. And beyond filtration’s support for greener mining, the financial and legal benefits of filtration technology can’t be denied. Learn more about some of the top benefits of filtration for the mining industry below.

Environmental Protection

Water is essential in the recovery and processing of metallic ore, resulting in a high volume of wastewater that must be handled with care. Wastewater from mining sites may contain any of the following:

  • Heavy metals
  • Acids
  • Bacteria, viruses and other biological contaminants
  • Radiological contaminants
  • Grease, soap, dyes, oils and other organic chemicals
  • Suspended solids
  • And more…

All of these substances can pose a serious threat to our supply of fresh, clean water, our soil and our health. However, by utilizing customized filtration equipment, miners can significantly reduce the effects of said wastewater. Proper filtration technology allows mining companies to remove pollutants before reusing water or reintroducing it into the ecosystem, ensuring they can stay compliant with increasingly strict EPA regulations.

Operational Efficiency

Through filtration, the mining industry is also able to cut back on operational costs and conserve energy. Recent research noted that in 2015, 4,000 Mgal/d (million of gallons of water used per day) were required to support mining activities, revealing the substantial quantity of water required to extract ore and other materials from the earth. In certain situations, however, filter press technology may allow mining companies to recycle and reuse resources rather than constantly relying on clean water. In addition, cleaner mining can result in fewer EPA fines, and a lower need for cleanup initiatives, saving time and money in the future.

A Path to Future Success

As society continues to become more environmentally aware, investing in filtration equipment is a smart move for the mining industry. It demonstrates a commitment to protecting our water and resources, as well as to the overall health of our planet and its people. By preserving earth’s finite resources, everyone can anticipate a brighter, more secure future.

New and Improved: M.W. Watermark™ AFPCS

In addition to automatically increasing the feed pump pressure during the filtration cycle, the new and improved M.W. Watermark™ Automatic Feed Pump Control System (AFPCS) also controls air-blow even-fill manifolds with the option to control double air-blow. This effectively combines multiple filter press functions in a simple control box – for a cost effective solution that is also expandable.

Digitally Programmable Controller

How the AFPCS Maximizes Filtration Efficiency

The M.W. Watermark AFPCS is used in conjunction with air-operated diaphragm feed pumps to automatically increase the feed pump pressure during the filtration cycle. High initial feed pump pressures can build a very tightly packed, impermeable layer of solids on the filter cloth, restricting the flow of slurry, and increasing filtration cycle times. Reduced initial feed pressure allows a soft layer of slurry particles to be deposited on the filter cloth. Because this layer becomes the filtering media, filtration of the incoming slurry is enhanced.

M.W. Watermark AFPCS Controller on Electrical Box - New and Improved - November 2018
M.W. Watermark Filter Press with AFPCS

The AFPCS automatically increases the feed pressure in four stages throughout the fill cycle. These stages and pressures are fully adjustable to suit the type of slurry and the solids concentration. Cycle completion is determined either by adjustable times (feed by time) or by monitoring the feed pump flow sensor (feed by flow).

The AFPCS also incorporates a low hydraulic pressure safety shut down device. If insufficient hydraulic clamping pressure is present, the AFPCS system will not start, or shuts down, eliminating possible leaking from between the filter plates and the potential to start the feed pump when the press is not fully closed and clamped. The AFPCS features power ON, START cycle and STOP cycle functions. The controller also indicates when the filtration cycle is complete.

The pump kit includes the pump air pressure regulator, 20-meter cables, 5-foot pump air connection hose, and 1/2″ & 3/4″ NPT pump air connection adapters.

Top 5 Uses for Recycled Wastewater

Across numerous industries, high-quality filtration equipment, like M.W. Watermark’s renowned filter press, is used to treat wastewater before it’s reused. But where exactly might this water go once it’s treated? Here, we’ll explore five common uses for recycled wastewater.

M.W. Watermark - Top 5 Uses for Recycled Wastewater

Agriculture

Water plays a fundamental role in agriculture, as it’s one of the key ingredients to a successful crop. However, there are often challenges that prevent farmers from watering their crops with typical water sources. Droughts, for example, require strict water preservation efforts in order to use what water is available for high-priority applications. Employing treated wastewater offers a helpful alternative for farmers who might otherwise have to deal with serious crop shortages.

Industrial Cooling

Most industrial machinery becomes exceptionally hot when it’s used, and a cooling agent is usually required to help keep this heat from damaging the machine. That’s where recycled wastewater comes into play. The water travels through a cooling system, where it absorbs heat created by the machinery and directs it elsewhere, where it won’t cause damage.

Toilet Flushing

Unsurprisingly, the quality standards for water used for human waste removal aren’t quite as rigid as those in place for drinking water. This makes wastewater the perfect match for waste disposal applications. Toilet flushing is commonly cited in discussions concerning wasteful water use, and recycling water for reuse in those very toilets helps make the system considerably less wasteful as a whole.

Concrete Mixing

The creation of concrete requires a great deal of water, no matter how it’s formulated. Some projects call for high-strength concrete, which requires less water, while others demand concrete that’s less stiff and therefore easier to work with. This involves increased water usage. Fortunately, studies suggest that treated wastewater is just as effective in concrete creation as distilled water, which marks one more area where recycled water can aid in conservation efforts.

Replenishing Wetlands

Recycled wastewater is commonly used to help create constructed wetlands. Sometimes, wastewater is even transported into these areas prior to treatment, as the soil and other elements present can typically treat the water naturally. This simultaneously conserves water and stimulates the development of wildlife.

Recycled Wastewater in Breweries

Exploring Wastewater in America’s Growing Brewing Industry

M.W. Watermark™ has often discussed how wastewater occurs in multiple industries around the world. Here, we’ll dig into how wastewater is used in the brewing industry, as well as how the wastewater created during that process can be recycled and minimized.

M.W. Watermark Manufactures Filter Presses for Many Different Industries and Applications, Including Breweries

Can Recycled Wastewater Be Used to Brew Beer?

Thanks to the less-than-appetizing imagery often associated with the term “wastewater,” it’s easy to think that it’s an unpleasant fluid packed with debris and harmful contaminants. Fortunately, by the time this water completes the treatment process, that couldn’t be further from the truth. In fact, recycled wastewater is used as drinking water in several places around the world, from Australia to Orange County, California and beyond.

Naturally, this means that properly treated wastewater is perfectly fit for use when brewing beers. A renowned California brewery, Stone Brewing, put wastewater into practice when it created a unique beer, entitled Full Circle Pale Ale, using recycled water. The beer was only available at a single event, but CEO Greg Koch reported it was gone in a few hours, suggesting that guests were attracted to the brew’s robust flavor and its environmentally friendly origins. Koch also explained that the water used was “cleaner than normal tap water,” which is possible with proper treatment. Stone’s Full Circle Pale Ale is just one example of how wastewater reuse can benefit areas, like Southern California, that are prone to drought.

Wastewater Created During the Brewing Process

While wastewater can be used to make beer, it’s also created during the process of brewing. Brewery wastewater typically contains high pH levels, which often requires breweries to use their own on-site treatment processes before their wastewater ever reaches a wastewater treatment facility. Highly efficient solid/liquid separation equipment, such as a filter press, is often required due to the solid sediments, such as yeast, that can be found in brewery wastewater.

CBD Oil Extraction from Hemp

With a growing number of states legalizing cannabis, it’s no wonder why the nation’s many cannabis-based companies are thriving. With increased legality, these businesses have also developed more ways to deliver the effects for which cannabis is known. One method that’s growing rapidly in popularity is through CBD oil extraction. CBD is an abbreviation for cannabidiol, a chemical compound derived from the hemp plant. CBD oil is used to treat a variety of medical conditions, and is now legal is most U.S. states.

M.W. Watermark Manufactures Filter Presses Utilized in CBD Oil Extraction from Hemp

But how exactly is this oil extracted?  The answer, of course, lies in filtration technology. Extraction methods vary, but filter presses are key in creating a reliable final product, which marks this industry as the perfect match for M. W. Watermark’s filtration technologies.

Two of the most popular CBD oil extraction methods using a filter press are known as Hemp Bio Mass and Winterization.

Hemp Bio Mass

Hemp bio mass utilizes a maceration process where ground-up hemp is mixed with a solvent such as ethanol. The solvent strips the CBD oil out of the plant fibers, and then the hemp oil/solvent combination is run through a filter press as a slurry. The solvent is then distilled off, resulting in pure hemp oil. The oil can then be further distilled and purified, if desired.

Winterization

Many plant waxes and fatty acids are soluble in carbon dioxide. The winterization method of extraction takes advantage of the differing solubility of waxes and cannabinoids at low temperatures. (i.e. minus 30 degrees Celsius or lower). Essentially, the frozen wax from the hemp plant containing cannabidiol oil is stripped from the plant using carbon dioxide. The wax is then separated from the solvent using a filter press.

Benefits of Using a Filter Press

Many businesses involved in CBD oil extraction from hemp are realizing multiple benefits from utilizing a filter press. For example, when a smaller operation moves from using basic filtration media such as brewery bags to the filter cloths found in a filter press, they are finding new levels of production efficiency and speed. Filter cloths are re-usable, versus brewery bags, which are designed for a one-time use. Also, brewery bags are hung up and the hemp is drained via the gravity method, which takes quite a bit more time than pressure filtration using a filter press. Ultimately, employing a filter press results in a more controlled production environment, contributing to a higher-quality product.

Another benefit is that M.W. Watermark offers FDA-compliant filter cloths and filter plates, as well as manifold piping and hydraulic oil and systems designed to combat contamination. Our selection of easy-to-clean equipment includes a stainless steel manifold with tri-clamp fittings, which is designed to be quickly disassembled for effortless sanitization.
