PowerDrain M

Compact version for low throughput. Combines ideally with PowerPress G and PowerPress E belt presses. Throughput up to 40 m3/h.

Belt thickener for the medium throughput range. Throughput up to 60 m3/h.

The highest capacity belt thickener with an exceptionally long filtration zone (6m). Throughput up to 180 m3/h.

Our decanter centrifuge fits in with our customers' needs

• Our rotor is the most polyvalent available on the market. Its specific design and open flight permit use of the entire volume and provide extremely good clarification results; extraction of sludge is simplified by the angle, and the acceleration (3000G) is a good compromise between the highest dryness and the right power consumption.

• The main operating parameters can be adjusted independently of one another and with high accuracy: bowl speed (efficiency of solid/liquid separation), relative scroll speed (residence time, hence dryness), pond depth (clarification). An unrivalled operational convenience.

• The polymer dosage is optimised: Flocculation is carried out at the feed in order to leave sufficient contact time for formation of resistant flocs; the distributor (feed chamber) shape avoids swift polymer passage with centrate whose residence time in the decanter is very short. Wellbalanced operating costs.

• Sizing is performed according to sludge type, flow, expected performance, operating time, power consumption, and polymer dosage... We provide advice and investigate your project with you...

• ANDRITZ service: "listen, design, check, support" are our key axioms. Our expertise and knowhow are appreciated all over the world!

Our hollow fibre membranes are manufactured from PVDF, a highly durable polymeric material that combines strength with high selectivity to filter out unwanted materials from feed water.

Hollow fibres operate under vacuum or pressure allowing feed water to pass into the fibre through microscopic pores, while rejecting particles. These particles may attach to the fibre surface, a phenomenon known as fouling.

The hydrophilic nature of our PVDF membrane minimizes attraction of solids and pollutants and thus reduces the fouling phenomenon. A key operational challenge is the control of fouling on the membrane surface.
