The Hydro Screw Press System consists of flocculation tank upstream of the screw press dewatering unit. Fabricated from high grade stainless steel 304 (316 available on request) this upward flow mechanical flocculation tank provides contact time for development of a liquid-solid separation and a strong floc formation. As part of package systems, Hydro International also offer Polymer Preparation and batching systems which complete automated batching and dosing of dilute Polymer to the Screw Press flocculation tank.
From the flocculation tank, the flocculated sludge gravitates to the screw press dewatering unit. Depending on the site requirements and model this can be a single or double screw arrangement. The screw press is mounted on a pitch to promote free draining of supernatant from the dewatering rings to the dewatering collection trough below. Hydro’s innovative self-cleaning mechanism consists of a set of oscillating rings attached to the screw press main drive motor, which provide continuous self-cleaning of the system.
The Hydro Screw Press can be offered in a range of installation configurations depending on site requirements and client preferences. We will offer a consultation service to find a solution which best fits your needs. Hydro International also provide turnkey solutions in the design and installation of dewatering system integration.
