Mobile Chamber Presses
The final sludge disposal route or application can economically influence the decision to use dewatering equipment. Important factors for this decision are achieving high dry solids in the cake and maximum solids capture rate in the filtrate. Our range of overhead skeleton design presses includes: Chamber filter presses. Membrane filter presses. Fully automatic filter presses. Mobile chamber presses.
The standard range of chamber press volume can accommodate from 200 litres to 19.4m3.
We also offer a range of belt filter presses and drum thickeners. Please call us for more details and a factsheet.
We specialise in tailor made solutions for our clients. We at DIRK will assess your requirements and using the expertise of our engineers, developed over a long period of time, will make a proposal to match your needs. DIRK is the sole UK importer for Klein.
How does a chamber press work?
Chamber presses are used for batch operation. Sludge with a dry solids content of up to 5% is pumped into the chambers by progressive cavity pumps or diaphragm pumps, with a pressure of up to 16 bar. The plates are held in place hydraulically, and by withstanding the pressure of the pumps thereby prevent the escape of sludge from the unit. The water in the sludge passes through the filter cloths and is discharged via filtrate channels. The solids are trapped and accumulate at the filter cloths.
The more the sludge is pumped into the unit then the more the existing cake is dewatered by the additional pressure, until the chambers are full. The dry solids in the sludge determine the quantity of sludge dewatered per batch.
However, trials have revealed that in comparison with filter belt presses and centrifuges, chamber presses achieve the highest results in the dry solids contents of cake.
