Sludge dewatering using a Rotary Press

In recent years, numerous sewage treatment and recycling plants have been constructed, employing various technologies. As part of the treatment process, sludge with a relatively low concentration of solids is generated, which requires drying/ dewatering in order for the treatment or removal to continue. Sludge dewatering allows for the removal of solids for a wide range of end-user solutions, from using it as fertilizer to removing it to landfills if needed.

Admir Environment offers ecological solutions for dewatering of sludge from the design phase through the implementation phase, including the construction of apparatuses at municipal sewage purification facilities.

Dewatering Using a Rotary Press

The Rotary Press is most advanced technology for dewatering organic sludge available today. This method is effective for dewatering of the raw, undigested sludge produced during the sewage treatment process. The dewatering mechanism is the buildup of friction between two filtration drums (registered patent) so that the sludge is compressed into them, and only wastewater passes through. The machine operates at a low rotation speed that significantly decreases wear and the expectation of failures this in turn reduces the cost of maintenance and personnel.

The machine is fully automated so that, after calibration, there is minimal to no need for qualified personnel. The Rotary Press offers a solution proven in multiple wastewater treatment facilities around the world. The Equipment is an extendable technology, allowing other channels to be added to the unit, in order to accommodate future increases in the flow. Up to six (6) channels can be mounted on the same press.

Advantages of using the Rotary Press in dewatering organic sludge:

• Significantly higher cake dryness of sludge.
• Lower transport costs due to higher cake dryness.
• Better quality of filtered water.
• Significantly lower maintenance costs.
• Low energy consumption in comparison to alternatives methods.
• Limited manpower required, fully automated.
• Extendable technology.
