Rotary Drum Screen

Reliable and well-proven inlet screen for wastewater and process water screening

The Rotary Drum Screens perform the functions of screenings removal, transport, washing, dewatering and compaction in a single space-saving unit specifically for sewage treatment plants and industrial applications.

The rotating drum screen is designed to separate solids present in effluents with compacting and de-watering of the screens.

Wastewater treatment plants and industrial applications for process and wastewater treatment require mechanical treatment as a first treatment step to remove as much as possible of the floating, settling and suspended material. The aim is to reliabily achieve the maximum separation efficiency under the prevailing hydraulic conditions.

The wedge wire Rotary Drum Screen allows combination of screening, washing, transport, compaction and dewatering in a single unit.

Depending on the screen bar spacing or perforation and screen size, the throughput can be individually adjusted to specific site requirements. The Rotary Drum Screen is completely made of stainless steel v wire and acid treated in a pickling bath.

The Rotary Drum Screen offers several benefits:

1. Low headloss – High separation efficiency:

Due to the drum‘s shape and 35° installation the screen area is much larger than that of a vertical or steeply inclined screen, which results in a low headloss, high separation efficiency and maximum throughput.

 2. No by-passing: 

The entire flow enters the screen drum through its open front end and can only leave the drum through its screen area. This prevents plant overflow and guarantees that the screenings are always retained within the screen drum.

 3. Several functions combined in one system: 

The screens function as a single space-saving unit for screening removal, transport, washing, dewatering, and compaction. An additional bagging unit ensures system operation without odour nuisance.

4. Completely made of stainless steel: 

The machine is completely made of stainless steel and pickled in an acid bath which eliminates corrosion and thus reduces maintenance.

The various application areas

Sifters are widely used in many activities:

--Wastewater pretreatment for municipal and industrial wastewater

--Storm overflow collection

--Wastewater treatment with high content of solids including fibers, wool, feathers and films.

--Effluents from paper mills

--Textile industry like dyeing, bleaching, etc…

--Chemical and pharmaceutical industry

--Rotary drum screens are highly recommended for any fixed culture process such as MBBR.
