Microscreen Drum filter

Highly efficient filtration for smaller applications Microfiltration and filtration

Microscreen Drum filters are the ideal solution for water filtration at wastewater treatment plants, in the paper and textile industries, power plants, heating plants, fish farms, zoos, and many other operations.

Our filters can also be found on hundreds of the world’s largest ocean cruise ships, where they treat wastewater that is subsequently discharged back into the oceans.

This demonstrates that our technologies are among the absolute best in the field, meet even the strictest international limits, and provide reliable filtration even in the most demanding conditions.

Microscreen Drum filter for municipal, industrial, and aquaculture applications, as well as cruise ships

Municipal wastewater treatment plants – the filter is suitable as a
- tertiary treatment stage – TSS removal, reduction of COD and BOD in the effluent, phosphorus reduction down to 0.1 mg/l. It is suitable for meeting strict discharge limits into receiving waters,
- quaternary treatment – use as pre-treatment for various PFAS removal technologies. The filter can be used in combination with powdered activated carbon dosing as a standalone quaternary stage,
- replacement of sand filtration – same or higher performance with dramatically lower energy and space requirements,
- optimization of existing WWTP operation – capacity increase without major civil works
Industrial operations – the filter is especially suitable for
- food and beverage industry
- textile and paper industry,
- power generation and heating industry,
- irrigation systems,
- influent water intake
Aquaculture operations (RAS – recirculating aquaculture systems) – in aquaculture, Microscreen Drum filters are among the key pieces of equipment.
- recirculating systems (RAS) – the Disc filter removes TSS, which directly affects fish health, also reducing the size of biofilters and increasing their efficiency
- flow-through systems (FTS) – removes parasites and algae, and stably and efficiently filters feces, feed residues, and fine organic particles even at high flow rates and in a small footprint
- protection of downstream technologies (UV, biofilters, oxygenation) – cleaner water ensures significantly higher efficiency and longer service life of downstream technologies

How does the Microscreen Drum filter work?

Water containing solid particles flows through the inlet pipe or channel into the inner space of the filter drum. Impurities are captured on the inner side of the cloth and the treated water flows out through the filter cloth. At this stage of the filtration cycle, the unit is in a resting position – the drum does not rotate.

As incoming impurities gradually clog the filter cloth, the resistance to flow increases and the water level inside the drum rises. When the set level difference between the inner and outer parts of the filter drum is reached, the level probe located on the front face of the filter automatically switches on the drum drive and simultaneously the washing pump(s), which pump filtered water to the nozzles of the washing system. The directed water jet from the nozzles removes impurities captured on the inner side of the cloth into a waste trough located inside the drum. Sludge flows into the sludge sump, from where it is pumped out by a sludge pump, which is also automatically controlled by level probes mounted on the sump wall. If gravity sludge drainage is possible, the sludge pump is omitted.

After the washing process is completed, hydrostatic resistance decreases. By rotating the drum, the washed cloth moves to the lower part of the filter, the level difference decreases, and the probe automatically switches off both the drum drive and the pump. Cleaned water flows over the overflow edge to the next treatment stage.

Filtration goes on continually without interruption.

Installation in a concrete channel

Primarily intended for gravity influent to the filter.

Installation in a steel tank

Option of both gravity and pumped influent.

Inlet and outlet connection by piping.

Unique "CLI-CLO" filter segments

This is a patented system with no need for screw fastening. The filter segments simply click into place.

The principle is a uniform supporting grid with different filter cloths for all filter sizes. Installation of the filter grid can be carried out very quickly, saving both maintenance time and spare parts costs.

All seals are integrated into the filter segment and together with the filter cloth form one single unit.

The individual filter segments are made of durable and recyclable ABS plastic and proven filter cloth that is easy to wash. This is very important for reducing wash water and electricity consumption.
