MITA® Pile Cloth Filter

Overview
The MITA® Pile Cloth Filter is an advanced cloth disk filter used in wastewater and reuse applications around the world. With over 1,000 units installed, it delivers high-quality effluent in a compact footprint. The technology combines pile cloth media with disk-filter construction to give depth filtration with minimal fouling, lower backwash costs, and simpler maintenance.

Key Features & Benefits

• Effluent quality to meet stringent reuse / discharge standards: NTU <2, TSS <5 mg/L, total phosphorus (TP) down to <0.1 mg/L.

• Multiple configurations: horizontal disks, vertical shaft disks, and small “mini” units.

• Efficient and low-impact backwash mechanism using molded suction shoes and submersible pumps. Rapid cleaning (<5 minutes) even for large filters.

• Smaller hydraulic profile and compact installation; many parts factory-installed to reduce on-site costs.

• Suited for both new builds and retrofits into existing concrete or stainless tanks.

How It Works

• Wastewater flows outside-in through pile cloth media, which captures solids by depth filtration. Filtrate is collected through internal channels.

• As solids accumulate, headloss increases until a backwash trigger is reached. Disks rotate past vacuum (“suction”) cleaning shoes to remove solids. Only a small fraction of surface is cleaned at any moment so filtration continues during backwash.

• A control system manages sludge removal from the basin, especially during high solids events or low flows.

Applications
Ideal for:

• Tertiary filtration and polishing of wastewater

• Reuse water production

• Phosphorus removal

• Stormwater / combined sewer overflow (CSO) management

• Pretreatment steps (membrane, lagoon effluent, etc.)

Why Choose MITA Over Fixed-Pore Media?

• Better resistance to fouling, due to depth filtration and flexible cloth fibers.

• Cleaner backwash using vacuum shoes instead of pressurized nozzles, resulting in less wear and lower wash water consumption.

• Easier to handle particles, debris, microplastics, etc., because of open backing and more dynamic media behavior.
