Benefits of PVDF Composite Membranes in Microfiltration

The Microfiltration Process

Microfiltration plays a fundamental role in removing bacteria and other contaminants from fluids. The microfiltration process, which is often used in beverage treatment and several other industrial processes, involves the use of filtration membranes with pores that vary in size based on the specific application. Another variable that should be considered, however, is the material from which these membranes are made.

Our premier microfiltration products, M.W. Watermark™/Porex® Tubular Membrane Modules™, are available with PE and PVDF substrates and equipped with PVDF composite membranes. Here, we’ll explore the benefits of PVDF in microfiltration.

M.W. Watermark™/Porex® Tubular Membrane Microfiltration Modules™

Why Use PVDF Composite Membranes?

When purchasing microfiltration equipment, your business has a number of options at its disposal. Here’s why you should consider PVDF composite membrane modules over alternative products:

Increased Durability

PVDF composite membranes offer enhanced abrasion resistance, helping to reduce the need to replace your equipment and thus making for a better value in the long run.

Omnidirectional Substrate Pore Structure

This unique design delivers reliable support for your tubular membranes.

Oxidant Resistance

PVDF resists oxidants, making it the go-to choice for preoxidized feeds and filtration of substances containing a high level of iron or other oxidants.

Additionally, you’ll have the opportunity to choose between various models, making it easy to find a product that suits your company’s unique needs.

How to Order the Right Size Filter Cloths to Fit Your Filter Press

Outfitting your filter press with the correct filter cloths is essential for effective performance. The cloth itself plays a fundamental role in the filtration process, acting as the starting point of the filter cake that will eventually do most of the filtering. With that in mind, it’s crucial to determine your filter cloth’s needed size in order to make the most of your filter press.

Making a Difference in our Workplace with Energy Efficient Lighting

M.W. Watermark team members know that making a difference in the world starts close to home.

Each year, the Watermark leadership team sets enthusiastic goals for community outreach projects, charity work and fundraising. This year, staff members have stepped up to make suggestions on how we can also make a difference right here in our workplace. In fact, one of our engineers, Reed, was interested in researching what we could do to save energy in our daily operations.

Our shop is similar to many other manufacturers’ in the fact that we have multiple overhead light fixtures to ensure both a safe and productive work environment.

Reed put together a cost/benefit analysis for switching to LED lighting and presented it to the Watermark leadership team. After reviewing the costs, it was determined that switching to LED bulbs would use only half the electricity and would pay-back in about 6 months.

Based on this proposal, M.W. Watermark decided to move forward with Reed’s suggestion for installing new energy efficient lighting in the shop. Besides saving energy, we were excited to see that the new bulbs are also brighter and provide a better quality of light.

M.W. Watermark Oil Coalescing Separator (OCS); Oil Water Separator
M.W. Watermark Oil Coalescing Separator (OCS)

Industrial Applications for the M.W. Watermark Oil Coalescing Separator

M.W. Watermark offers our OCS in a wide range of sizes in order to appeal to the needs of several industries, including, but not limited to:

Aviation

Because aircraft are so large, the water used in the washing process may collect a great deal of grime and oil, which makes for an excellent chance to put the M.W. Watermark OCS to work. The separator will leave the water virtually oil-free, allowing it to be reused and helping to prevent unnecessary water waste.

Automotive

From bus terminals to general-purpose vehicle washes, the automotive industry offers ample opportunity to take advantage of our OCS.

Groundwater Remediation

A variety of human activities, from pesticide to landfill leakage, can cause significant groundwater pollution. These contaminants can be at least partially addressed with the M.W. Watermark OCS.

Marine

Separators are common components on ships, where they’re used to help purify oily bilge water.

Oil/Petroleum

The collection and refinement of petroleum is the perfect match for our OCS, because it results in a massive amount of oily wastewater, the treatment of which is subject to strict regulations.

Power Production

Most types of power plants require the use of both oily lubricants and water throughout their systems. An OCS can help ensure that when leakages and contamination occur, the lubricants can be thoroughly separated from the water for easy disposal.

Other Industries and Applications

Other businesses that can benefit from the M.W. Watermark OCS include chemical processing plants, paper mills, steel mills and much more. For assistance in selecting an OCS that meets the needs of your industry or for more information about our available wastewater treatment products, reach out to M.W. Watermark online or by phone at (616) 399-8850.

How to Determine the Size of Filter Press Needed for Your Application

M.W. Watermark 800mm Filter Press

A filter press is a piece of batch operation, fixed volume equipment ranging from .01-600 cubic feet that separates liquids and solids using pressure filtration. A slurry is pumped into the filter press and dewatered under pressure. (A slurry is a semi-liquid mixture, typically composed of fine particles suspended in water).

A filter press can be used for process, water and wastewater treatment in a variety of industries and applications. In most applications, filter presses are used for dewatering solids prior to disposal. However, in some cases the separated solid or liquid is the actual product.

Because filter presses are used across so many applications, there is no “one size fits all” when it comes to determining filter press sizing requirements.

Fortunately, over the history of commercial businesses and municipalities utilizing filter presses for a multitude of applications, two basic and reliable mathematical formulas have been developed to cover most situations.

The first formula covers most “standard” slurries. The second formula covers slurries composed of metal hydroxides, which are often found in wastewater from metal plating and finishing operations.

Filter Press Sizing Formulas

Standard Slurries

M.W. Watermark Filter Press Sizing Formula: Standard Slurries

Metal Hydroxide Slurries

M.W. Watermark Filter Press Sizing Formula: Metal Hydroxide Slurries

M.W. Watermark’s goal is to help our customers make the most informed equipment and equipment sizing decisions possible.

Our team’s many years of experience across a wide variety of filter press applications provides a knowledge base that serves our customers well.

Feel free to contact M.W. Watermark at any time to discuss your particular solid-liquid project.

Please work to obtain in advance as much of the information as possible outlined below. If one or more criteria are not available, M.W. Watermark can test a sample of the slurry, and/or use some standard data. (See Laboratory Testing section below for more information).

Information Needed to Size and Quote a Filter Press

• Type of slurry to be processed

• Amount of slurry to be processed in a given amount of time expressed in either:
—Gallons per minute, per hour, per day or per week
—Pounds of solids (100% dry basis) per time period

• Number of hours per day, and days per week the process operates

• Percent solids (by weight) in slurry

• Specific gravity of slurry (if available)

• Process operating temperature

• Density of wet filter cake

• Chemical conditioning amounts, if required (D.E., etc.)

• Press location: Indoor or outdoor, temperature range

• Desired cake thickness (std. is 32mm – 1 1/4”)

• Desired closure & control automation (Specify: Manual, Semi-Automatic or Automatic)

• Other (Please specify optional features required)

Laboratory Testing

M.W. Watermark maintains an in-house laboratory for determining the most effective equipment, equipment sizing, filtration media and dewatering techniques for your specific application.
