What Is The Difference Between A Cartridge Membrane Filter Plate?

In the filter world, the two common kinds of Filter Plate s are membrane filter plates and cartridge filter plates. Membrane filter plates work by forcing water through the pores of the plate by pressure and back-pressure, while cartridge filter plates use gravity to draw water through its channels before trapping contaminants using one of many filtration methods like microfiltration, ultrafiltration, nanofiltration or reverse osmosis. It’s important to choose the right kind of filter plate for your application to get the best efficiency, clarity and longevity from your system.

Filter Plates

A filter plate with membranes consists of two parts: (1) A round or square/rectangular frame that holds metal or plastic, depending on the design, discs stacked tightly together. (2) The metal discs have holes that allow liquids to flow through. These two components sandwich a thin sheet of fabric and form rooms where water and other liquids accumulate and rise on the side of each disc.

The Automatic filter press are great for removing particles but they are not able to remove dissolved substances in water such as chlorine or heavy metals.

Chemical Filters

A membrane filter is also used for the removal of microorganisms such as bacteria and viruses. The process relies on a filtration system made up of two layers: a thin layer of porous hydrophilic polymer membrane bonded to an impermeable backing material or layer. One side of the membrane bears pores of some size, while the other has larger holes so that fluids can pass through them. A second element (the support) prevents fluids from passing through these holes in case they have not reached minimum size yet due to pressure, gravity or capillary action.

Mechanical Filters

While what’s captured in a membrane filter may be just micrograms, it can’t do its job without an engineered frame that supports it. The exact dimensions and construction materials depending on the chemical and physical conditions that are encountered by that part of the membrane. As you can imagine, there are plenty of tradeoffs to consider: permeability, selectivity, chemical resistance, cost-effectiveness…the list goes on. However, manufacturers use filters as guards against premature clogging and particle separation issues. So how do they decide which one to choose? Read on!

A cartridge membrane filter usually has an inner metal or synthetic fibre mat (or basket) that contains many membranes bonded together into a porous sheet. The basket sits inside a cylindrical outer housing with holes for fluid flow through the mat and out of the holes at the bottom of the housing where filtered fluid exits from.

Air Stripping

In the air stripping method, the carbon from the filters or substances from the plates works to absorb pollutants from passing gas. As gasses pass through it, pollutants will attach themselves to molecules of carbon or other adsorbent materials. Particles that have been removed from gas streams in this manner are referred to as scrubbed. These scrubbed particles can then be collected for disposal. The amount of pollution eliminated by this method is dependent on several factors including temperature and reactivity of individual compounds and concentrations of compounds in the air stream being treated. However, with proper care, nearly all types of airborne particulate matter can be eliminated.

The most significant advantage of air stripping is its ability to remove odours and provide better indoor air quality.

Additionally, because there are no contact parts such as an electrode grid that come into contact with the gas stream, maintenance costs are reduced.

For filtering methods like activated charcoal filters or membrane filters to operate properly, they need something called contact time where pollutants remain in contact with them long enough for some fraction of them to bind with them (either permanently or temporarily). Contact time varies depending on the type of pollutant but most common applications require 20-30 minutes of contact time before 70% removal efficiency is achieved.

Filtration Tips And Resources

A membrane filter removes particles or contaminants from water or gas. They come in many shapes and sizes, but all have a thin layer that lets fluids through while blocking particles. A membrane filter is made up of synthetic fibres spun into long strands, so small that water molecules can go through without getting trapped. This process does not remove bacteria, but it will remove dirt and sediment that contaminates our drinking water.

Membrane filter plate are used for everything from food safety to filtering hazardous gases from industrial processes. Along with sand filters, they’re often used in breweries to improve beer clarity by removing any grain particles suspended in the fluid after fermentation.
