Membrane Filter Press

Membrane Filter Press: A Versatile Tool for Various Industries

A membrane filter press is a special and advanced type of the regular filter press. Many industries use it a lot for separating solids from liquids. This advanced machine has a flexible or stretchy membrane inside the filter chamber. We make the membrane from materials like rubber or elastomers.

Membrane filter presses are used in many different industries. These include wastewater treatment, chemical processing, mining, pharmaceuticals, and the food and beverage industry. Wherever we need to separate solids from liquids efficiently, membrane filter presses are important. They make industrial operations more productive overall and also reduce the harm to the environment.

Membrane filter press with acid station for chemical filter cloth cleaning

A membrane filter press with an acid station for cleaning filter cloths chemically is an advanced system. We design it to make filter cloths in different industrial uses more efficient and last longer. This setup is really helpful in industries where filter cloths come into contact with strong chemicals or when keeping high filtration efficiency is very important.

How It Works

1. Charging the Filter Chamber: The slurry is pumped into the filter chamber.
2. Initial Filtration: The liquid begins to pass through the filter cloth, leaving the solid particles behind.
3. Membrane Inflation: The membrane is inflated, pressing against the filter cake.
4. Enhanced Dewatering: The pressure from the inflated membrane squeezes additional liquid out of the filter cake.
5. Final Filtration: Any remaining liquid is filtered out.
6. Cake Discharge: The dry filter cake is discharged from the press.
7. Chemical Cleaning: The acid station is activated to clean the filter cloths using a chemical solution, typically an acid, to remove any residual contaminants and restore the cloth’s filtration efficiency.

Key Advantages of Membrane Filter Presses

1. Higher Filtration Efficiency
   • Membrane filter presses can make filter cakes much drier than traditional ones. This means they can reduce the amount of liquid waste. When the cakes are drier, there’s less liquid left over from the filtration.
2. Shorter Cycle Times
   • The membrane squeezing part in membrane filter presses speeds up the filtration. Because of this, the whole cycle of filtering takes less time. Shorter cycle times mean we can get more work done in the same amount of time, so productivity goes up.
3. Improved Cake Quality
   • The membrane helps create a filter cake that’s more even and the same all over. Such a uniform cake is easier to pick up, move around, and get rid of later.
4. Reduced Environmental Impact
   • Membrane filter presses make drier filter cakes and cut down on liquid waste. By doing this, they help make the filtration process have less of a negative effect on the environment.
