Overview

Overview

The Hydro-Sludge® Screen removes, compacts and dewaters solids from municipal and industrial wastewater sludge to reduce handling costs, increase the calorific value of biosolids and improve overall treatment efficiency.

A small-footprint, low-maintenance system designed to work early in the sludge management process, the Hydro-Sludge® Screen can handle dry solids of up to 9% and delivers screenings at up to 40% total solids—enabling engineers, operators and owners to protect valuable equipment, reduce blockages and increase the efficiency of downstream treatment processes such as anaerobic digesters.

The Hydro-Sludge® Screen generates a drier output that is easier and cheaper to handle and transport, whether for disposal or as a higher-value biosolids product for energy generation and other secondary processes.

Benefits

Improve downstream process efficiency

Offering a range of screen sizes, the Hydro-Sludge® Screen reduces loading on downstream processes and improves overall treatment effectiveness. Able to handle a dry solids capacity of up to 9%, the equipment removes solids early on in the sludge management process, minimizing the clogging that would otherwise reduce subsequent treatment efficiency.

Cut maintenance costs

With an easy-maintenance standard design and optional enhanced maintenance package, Hydro-Sludge® Screen has been developed with the operator in mind. A self-lubricating cone cuts maintenance requirements, and a re-engineered discharge section provides easy-access servicing, making routine inspection, cleaning and maintenance activities quick, simple and safe.

Save money on solids handling

Delivering screenings at 40% total solids, the Hydro-Sludge® Screen removes, compacts and dewaters coarse material in sludge to reduce the solids handling burden, cutting the cost of screened solids management, transport and disposal.

Reduce operational costs

The Hydro-Sludge® Screen reduces the dewatering required for screenings – cutting the cost of process water.

How it works

How it works

Flow enters through the center of a sludge inlet. Sludge passes through the perforations in the screening zone and exits via the sludge outlet, while the coarse material (screenings) are trapped inside.

The coarse screenings are retained on the stainless steel inner screen surface and then transported to the stainless steel pressing zone and onward to the outlet by an archimedean screw. In the pressing zone the screenings are pressed against a retention cone which is balanced against the drive load of the screw.

Dewatered and compacted screenings are finally discharged by the action of a regulating cone, controlled by detection of increased torque on the drive motor, into a suitable container.
