MMF stands for Multi-Media Filters are a cost-effective and efficient way to remove suspended materials from a waste stream. It is used for primary treatment in streams with low TSS levels. After an initial treatment, such as an inclined plate clarifier, they are an ideal secondary treatment option.

The purpose of a Multi-Media Filter is that it reduces the amount of suspended particles (turbidity) in incoming input water. Small particles like silt, clay, grit, organic debris, algae, and other microorganisms make up suspended solids. High-suspended-solids incoming input water can create a high-pressure drop and impair the performance of downstream filtering equipment including such reverse osmosis membranes or ion exchange beds.

In other words the process is that the MMF unit is provided to remove suspended solids which are present in the raw water. The water is to be fed from the top; water flows downward through the filter bed and exits from the bottom.

During the course of filtration, the bed is compacted raising the differential pressure across the unit and then requires backwash. The backwashing of MMF is to be done manually by the raw water. The MMF is backwashed for 10 to 15 minutes after every 23 hours.

How does it work?

The waste stream enters the filter vessels from the top. While the water flows through the filter media, the particles become trapped in the media bed as the wastewater moves downward. The clean effluent is discharged or treated further after passing through an output header. The pressure inside the filter rises as the solids pile up on the media.

The medium has reached its loading capacity and must be backwashed at a particular pressure. Backwashing the filters reverses the flow of water through each filter one at a time. Water enters the vessel's bottom, expanding the filter medium and releasing the trapped solids. The filters restore to their previous filtering capability after all of the containers have been backwashed.

What are the benefits?

• Captures 90% or more of particles with diameters of 20 microns or more.
• The triple cell design offers the highest flux rate for filtering and backwash operation.
• The use of 5 layers of media improves filtration capacity and necessitates less backwashing.
• There are no consumable charges like filter bags or cartridges.
• Valves can be manually, electrically, or pneumatically activated and positioned on a skid.
• Vessels made from FRP, coated steel, or stainless steel
• Flow rates range from 5 to 1000 GPM.

Why is it necessary to use Wattek Multi Media Filter?

• Increased service life - unlike sand filtration, where just the top layer is used for filtering. As a result, pressure rises more slowly, lengthening the period between filter backwashes.
• Because of the greater filtration velocity rates attainable with pressurised filtration, the size of equipment for your operating loadings can be up to 60% lower than identical gravity sand filter models.
• Energy Efficient: Air blending isn't necessary, thus there's no need for the extra energy. Our media's distinct specific gravities allow it to divide into layers without the need to air mix. The media's life is also extended as a result of this.
• Reduce or eliminate the use of chemicals - Wattek's proprietary medium promotes the spontaneous aggregation of suspended particles, often known as spontaneous flocculation. For removing suspended particles, this negates the need for costly chemical flocculants.
