How a Commercial Car Wash Can Reuse Water and Save Money

Each time you wash your car, wastewater is created – it’s unavoidable. However, using a commercial car wash (either automatic or self-serve) rather than washing your car at home can help save water thanks to water recycling processes integrated into modern washing systems.

Automatic Car Wash Water Consumption

While it might seem like automatic car wash systems use excessive amounts of water, updated technology has made it considerably easier for owners to use water reclamation systems. These systems are designed to cleanse used water of debris, making it suitable for reuse. This helps minimize the amount of freshwater lost during each wash cycle – something that is simply not plausible during an at-home car wash.

While the average amount of water used by automatic car washes fluctuates, the water reclamation systems used in many washes help keep numbers quite low. According to the International Car Wash Association’s report, Water Conservation in the Professional Car Wash Industry, on a gallon-per-vehicle (gpv) basis, professional car washes use between 30 gpv for in-bay automatics to 70 gpv for frictionless conveyor car washes. However, the actual amount of water lost can be much less, depending on several factors, like the car wash design and season.

Self-Serve Car Wash Water Consumption

According to the Southwest Car Wash Association, a self-service car wash uses roughly 17-18 gallons of water per car – which is in stark contrast to the average 100 gallons or more of water used in standard home car washes as cited by the Western Car Wash Association. This is likely because, as a business, commercial washes are faced with not only the rising cost of fresh water, but also disposal costs along with rigid environmental regulations. To run their operations more efficiently while complying with regulations, wash owners can integrate a wastewater reclamation system.

Environmental Responsibility

Aside from repurposing valuable water, water reclamation systems used in car washes reduce disposal costs while helping to prevent detergents and other chemicals from polluting the environment. One method of water reclamation involves using a filter press, which is available through M.W. Watermark. Designed to remove solids from wash water while allowing soaps to be reused, our filter presses offer an easy opportunity to reduce the environmental footprint of your wash while maximizing its efficiency.

Using Filter Presses to Recycle Flowback and Produced Water

What is Hydraulic Fracturing?

Hydraulic fracturing (informally referred to as “fracking”) is an oil and gas well development process that involves injecting water, chemicals and additives (known as proppants) under high pressure into a shale rock formation. To keep fissures and fractures open, proppants such as sand or ceramics are commonly used. This process is intended to create new fractures in the rock as well as increase the size, extent and connectivity of existing fissures to reach oil and gas deposits. (Source: USGS.gov).

The hydraulic fracturing process requires the management of a great deal of water for the extraction of oil and gas. First, a substantial amount of water is used for the initial injection process. According to the USGS, water use can range from 1.5 million to about 16 million gallons per hydraulically fractured well depending on the nature of the rock formation and other factors. Next, the issues of flowback and produced water must be considered.

Flowback Versus Produced Water

Flowback water is a combination of the water, chemicals and proppants pumped into the ground that return to the surface over time as a result of pressure. Most of the flowback occurs in the first seven to ten days, while the rest can occur over a three to four week period. The flowback can be anywhere from 20 to 40 percent of the volume initially injected into the well. The remaining fluid is absorbed into the rock formation. (Source: idl.idaho.gov).

At some point in time, the water recovered from the well makes a transition from “flowback” to “produced” water. Produced water is composed of the minerals, petroleum residue, salt and other contaminants already present in the ground.

While flowback water can be considerable, it is the produced water that creates a much larger challenge for producers. On average in the U.S., between five and six barrels of water are produced for every barrel of oil that comes out of the ground. The Permian Basin in West Texas produces an even greater amount of water, at six to eight barrels of water per barrel of crude. This is equivalent to over 1,000 Olympic-size swimming pools full of water coming out of the Permian Basin alone each day! (Source: rbnenergy.com).

When collected from a well, the combined flowback and produced water contain a high amount of contaminants along with the original proppants. Producers must first clean and then either recycle or dispose of the water in a safe, environmentally responsible manner. Because of the sheer volume of water resulting from hydraulic fracturing operations, along with the need for a substantial amount of water on the front end of the process, many companies are now treating this water for reuse.

The Role of Filter Presses

Filter presses are often used as part of the water treatment process, separating the solids that are precipitated out of the water. A filter press can capture the majority of the particulate matter, and then the clean water can be routed back to the beginning of the process.

Responsible Treatment of Hydrocarbon Production Waste

As oil and gas industries continue production and eco-awareness grows, the need for adequate byproduct disposal arises. Drilling and fracking as a means of resource extraction result in many contaminated byproducts. One such side effect is produced water, or the mixture of water, hydrocarbons, gasses, naturally occurring radioactive materials, and other chemicals. Produced water treatment companies provide services and equipment for the recycling or disposal of this water.

Produced Water Treatment Companies - M.W. Watermark - Filter Presses

Mother Earth’s Sources

Water is commonly found in drilling and hydraulic fracturing sites. Liquids are trapped in the sedimentary rock found around the reservoir. Likewise, liquids are condensed via gas production. In injection wells, water, steam, and other chemicals are pumped into the ground to increase production. The physical and chemical properties of the solutions that produced water treatment companies seek to purify differ according to several factors. The makeup of the fluid can vary depending on its geographical location or the geology of the reservoir.

Standard Refining Methods

Techniques also differ in the treatment process. These include filtration, absorption, and oxidation among others. Filtering the liquid using sand or anthracite coal is an energy-saving option. Filter presses, machines which separate solids from liquids using pressure filtration, can be utilized for this purpose. Contrarily, absorption uses zeolites or organoclays to decrease impurities. Chemical use is minimal but the media used to absorb is commonly consumed and compromised. Oxidation, although costly, uses chemicals such as chlorine to remove both organics and inorganics. Flotation and evaporation are also among the multiple other methods that exist. Technology and research in this field of study add to the future of the industry.

Responsible Disposal

Produced water treatment companies focus their efforts based on the method of disposal or the recyclable possibilities. Considered industrial waste, the byproduct, or cleaned water, is subject to strict regulation by governing authorities. Many sites dispose of this byproduct in the sea, evaporation ponds, or wells. Pumps from the filtering process can also push the clean water back into the production or injection process.

Produced water treatment companies, through various methods and technologies, repurpose the planet’s most valuable natural resource. As the petroleum and gas industry provide energy to people across the world, preserving the environment is a top priority.

How to Maximize the Life of Your Filter Cloths

Filter presses need regular maintenance to continue operating at optimal performance levels. An important part of this care is servicing the filter cloths.

As the initial barrier that removes solids from liquid in the filtration process, filter cloths experience a great deal of wear and tear. It’s important that they stay porous to achieve good filtration rates. When fine particles become lodged deep within the fabric, filtration rates can become compromised. Cleaning must be done on a regular basis to maintain full functionality of the filter press.

Filter cloth life can be shortened by certain chemicals in the slurry, mechanical wear, abrasion and blinding. Mechanical wear can be reduced by using a more durable cloth. Blinding (clogging of the cloths) often comes from “slamming” sludge into the press.

Preventative Measures

Automatic Feed Pump Control System (AFPCS)

Consider an Automatic Feed Pump Control System (AFPCS) to automatically and gradually increase pump pressure during the filtration cycle. High initial feed pump pressures can build a tightly packed layer of solids on the filter cloth. By reducing the initial feed pressure, a soft layer of slurry particles can be deposited on the cloth. Because this layer then becomes the filtering media, the filterability of the incoming slurry is enhanced.

An AFPCS can be retrofit to any filter press. Learn more about how an AFPCS allows your filter press to run at its optimum efficiency.

Pre-Coat

Pre-coat material is any porous substance that allows liquid to pass through. The substance should be fine enough to mix with water but not so fine as to be impassable. It is the gaps within the substance that will provide much of the actual filtration.

“Pre-coating” a filter press with perlite, diatomaceous earth or similar products can also add substantial life to cloths. This coating protects against wear and minimizes blinding.

Learn more about pre-coat and how it is applied in a filter press.

Cloth Additions

If your filter cloths are wearing out prematurely at the center feed, a latex-reinforced cloth barrel neck can help. In cases of an especially high amount of abrasion at the neck, a rubber barrel neck can help protect that area.

Cleaning Methods

Using a Pressure Sprayer

When filtration cycles become too long or the initial filtration pressure is too high, it’s time to clean the cloths. One of the easiest ways to accomplish this is by using a portable cold water pressure sprayer, as the plates do not need to be removed from the filter press. However, care must be taken when using a pressure sprayer to ensure that the cloths are not damaged. By using a fan-shaped spray pattern and staying back a few feet from the surface, the cleaning process can be accomplished without accidentally cutting the cloths. Keeping the spray pressure under 1,000 PSI is recommended as well.

Acid Washing

Polypropylene filter cloths can handle both caustic and acidic solutions, and acid washing has become a popular cleaning method for this type of cloth for specialized applications. For example, when working with sludge from metal finishing, even the best-matched cloths can blind (become clogged) after a short period of time.

In cases where frequent cleaning is required, acid washing can become the most practical method of cleaning cloths. Plates do not need to be removed from the filter press, and a filter press can be equipped with a special manifold and system for cloth washing.

However, other filter cloth materials such as nylon, polyester and felt cloths may become damaged by using chemical cleaners.

Also, it’s important to note that acid washing is only an option if the chemistry of the sludge is reversible. Therefore, acid washing is not effective in situations that include laundry, food waste and biological applications.

M.W. Watermark has filter cloth experts on staff that can help you determine the best cleaning method for your particular application, and also talk through important safety precautions.

How to Save Money in Metal Finishing While Remaining Environmentally Friendly

Metal plating and finishing requires an ample amount of various chemicals for an efficient operation. However, the chemicals found in these wastewater streams are not only expensive to remove but also potentially damaging to the environment. Read on for tips for avoiding these negative impacts as well as industry best practices for wastewater treatment and disposal.

Collecting the Right Information

When it comes to metal finishing wastewater treatment, it’s important to understand certain baseline information. Four areas to keep in mind are rinse tanks, ventilation systems, acid cleaners and acid etches, and alkaline cleaners. Making a layout of these areas to collect appropriate information can help clarify the process and build awareness of initial costs.

M.W. Watermark Metal Finishing Wastewater Treatment Equipment

Rinse Tanks

The metal finishing industry involves processes that use more water than many other industries, resulting in stringent EPA regulations. The most cost-effective and environmentally sound options for metal finishing wastewater treatment are multiple counterflowing immersion rinse tanks, reactive rinsing, spray rinsing, and combination rinses.

Metal finishing operations have an in-house treatment system so that acids, alkali, oils, and dissolved metals are economically disposed of and sent to sewers since the water becomes unsuitable for use again. However, reverse osmosis, a relatively simple and low-maintenance system, can help recover at least half of the water and make it safe for use.

Ventilation Systems

Ventilation systems remove dangerous fumes from process tanks. The highest cost involved with ventilation is the electricity used for the operation. The secondary cost depends on the location and the reconditioning (heating or cooling). Some industries utilize automatic tank covers and fan controls, which can reduce the fumes, thus resulting in lower costs.

Acid Cleaners and Acid Etches

Acids used in metal plating are cleaned via acid baths. If the acid bath does not have effective process controls, it can lead to defective metal plating and finishing over time because of inconsistencies in the acid strength level. An ineffectively managed acid tank can become useless and will have to be disposed of, resulting in costs to replace the tank and the acid cleaners. To extend the life of the acid bath and reduce costs, any dissolved metal content should be removed through metal dissolving methods such as diffusion dialysis and acid sorption.

Alkaline Cleaners

During metal finishing wastewater treatment, alkaline cleaning tanks clean a large amount of dirt, oils, grease, wax, polishing compound, and light oxides at the beginning of the process. It is important to keep track of the cleaning strength of the alkaline cleaners to reduce costs and the environmental footprint.

 Metal Finishing Wastewater Treatment

The metal finishing process produces wastewater that must be treated to separate the dissolved metals in the wastewater from the liquids following chemical treatment and precipitation. A filter press with polypropylene filter plates and cloths is typically used, as polypropylene is resistant to the corrosive nature of this type of waste stream. Gasketed filter plates and cloths (versus non-gasketed) are also well suited for a corrosive slurry, as there is less chance of leakage.

After the metal finishing wastewater has been processed via pressure filtration, the resulting filter cake is then discharged from the filter press. The filter cake can then be further dehydrated using a continuous sludge dryer.  For example, the M.W. Watermark continuous sludge dryer can reduce the waste volume and weight significantly, offering an average yearly savings in disposal costs of up to 60%.

How Does an Oil Coalescing Separator Work?

The M.W. Watermark Oil Coalescing Separator is designed to remove free non-emulsified oils, diesel, gasoline and fuels from a waste stream, resulting in an effluent quality of 10 mg/l or less of contaminants 20 microns and larger.

M.W. Watermark Oil Coalescing Separator

The Oil Coalescing Separator operation is based on closely spaced oil attracting media that promotes the impact and formation of larger oil particles. As the oil droplets increase in size their rise rate to the water surface also increases.

The influent water enters the separator through an inlet baffle that directs the water through the media bundle. The media expands the surface area of the separator giving the oil more room on which to combine.

As the oil droplets accumulate on the media and coalesce they develop into larger droplets that flow up the surface of the media, detach and rise to the water surface. Surface oil decants by gravity into a segregated oil reservoir where it can be removed from the tank.

Heavier solids will slide down the surface of the media into the sludge chamber at the bottom of the tank for periodic removal. Virtually oil free water travels under an oil reservoir baffle, over an adjustable weir and into a clean water effluent chamber. The water is then gravity discharged from this chamber.

M.W. Watermark Offers 19 progressive sizes of Oil Coalescing Separator models

Our OCS models range from 10 gpm to 5,000 gpm.

All of our high-quality Oil Coalescing Separator models are assembled in the U.S.A.

M.W. Watermark has recently added Frazier® Air Permeability Testing to our growing list of laboratory services.

By using a Frazier® Air Permeability Tester, we are able to determine the air permeability of a particular filter cloth fabric, utilizing the ASTM D 737-96 standard test method for textile fabrics.

M.W. Watermark Air Permeability Testing - Laboratory Services
M.W. Watermark Air Permeability Testing Station
How does it work?

A sample is placed on the machine and air is drawn through the fabric. The rate of air flow passing through a fabric sample is adjusted to find an air pressure differential between two fabric surfaces. The air permeability of the fabric can then be determined by this air flow rate. The test results are reported in CFM, or Cubic Feet per Minute.

Efficiency of filtration media is directly related to air permeability. By testing the air permeability of a filter cloth fabric, our lab technicians are able to determine the filtration characteristics and determine if a given fabric is ideal for a customer’s particular dewatering application.
