The rotary screen is a drum sieve loaded from inside for separating suspended solids, particles and fibres from liquids, process water and waste water.
The rotary drum can be equipped with different types of sieves or filters like perforated metal plates, wedge wire screens and fabrics. This leads to a wide range of applications for various types of mediums.
So it is also possible, for example, to treat hot washing and process water. It can be used as a washing drum for the dewatering of special products as well
The feed stream is led into the sieve drum (❷) via the inlet pipe (❶) and is spread evenly on the drum surface. The actual sieving process takes place inside the continuously rotating sieve drum.
The untreated water flows from the inside outwards through the filter drum into the collector for the clear water (❸).
The solids are retained by the drum and carried to the solid output (❺) by a screw conveyer (❹) where they fall into a sludge tank. The rotating sieve drum is cleaned continuously by a brush roller (❻). In addition, an outside of the drum mounted sprayer with nozzle assembly (❼) is used for rinsing.
Our products are available to rent for pilot tests. Due to our extensive rental park, we can put together complete test systems individually for your task.
The rotary screen can be dimensioned up to a throughput of 3000 m³/h. Optionally the drum can be equipped with an additional inlying nozzle assembly for washing the solids.
