Sludge dehydrator descriptions

A screw press (SP) provides sludge dewatering by conveying the sludge along the inside of a permeable cylinder. It is based on a slowly-rotating (~5 RPM) Archimedean screw within a cylindrical screen (otherwise termed drum filter/screen or basket). It is normally inclined by ~20° to the horizontal to assist with the draining of water into the sump. The screen generally has an aperture rating below 0.5 mm and is based on wedge-wire or occasionally perforated metal.

Sludge dehydrator process

Mechanical Preliminary Treatment

DAGYEE Solutions for mechanical wastewater pre.treatment: Contaminants and solids contained inwastewater are removed by screens and fine

screening systems as well as through sedimentationand separation processes.

Advanced Wastewater Treatment

The aim of advanced wastewater treatment is thereduction of one or more of the following pollu-tants: solids,COD, BOD, phosphorus, nitrate, mi-cropollutants and germs.

Elimination of Trace substances

DAGYEE offers solutions for the elimination of trasubstances and micropollutants from wastewatelwith qranulated activated carbon(GAC) and povdered activated carbon(PAC).

Sludge Treatment

DAGYEE offers highly efficient and comprehensivesolutions for sludge treatment, from mechanicalpre-treatment with screens to drying andincineration.

Screening in Pumping stations

Reliable screening and solids removal for pumpsand lifting units at combined and separate sewersystems. HUBER pumping station screens maintainthe operating stability of the pumps and protectthem against interfering substances.

Sludge dehydrator key features

This series of screw press machines are suitable for the pressing and dewatering of solid materials like sludge and other solids, such as some waste food materials and other industrial wastes.

The main body of the sludge dewatering machine can be divided into two parts: in the first part where gravity concentration occurs, the screw will rotate downward and push out a mixture of water and solid materials that are below it.

In the second part where there is no gravity concentration, but with pressure generated by the rotating screw, pressure is applied to keep the solid materials pressed between rings so that they can get dehydrated by moisture vaporization during operation.
