Cylindrical Grit Separator / Compact Unit WS

Saving up to 50% of the space required by conventional compact units and with the same grit separation performance as well as a significantly enhanced operational accessibility. The separation efficiency of up tp 95% has been demonstrated for a grit size dwon to 0.2 mm. On account of the Flat Fine Screen with integrated Screeings Was Press and the efficient fat and scum separation used in this unit it is an extremely low-maintenance and low-wear system. The separator does not require a separate belt scraper for fat and floating matter. The Cylindrical Grit Separator/Compact Unit WS distinguishes itself from other designs by its reduced power consumption resulting from the lower inflow height when using feed pumps and the lower air injection depth of the grit separator aeration, among other features.

Another advantage compared to conventional units are the reduced construction costs. The Cylindrical Grit Separator/Compact Unit WS normally represents the most economical solution for mechanical pre-cleaning. The waste water feed entering the grit separator tangentially from the screen grid starts the desired spiral flow which additionally is supported by a bubble aeration along the whole cylindrical tank. This optimized spiral flow significantly improves the separation efficiency and leads to shorter girt separators. This was already proven decades ago, both scientifically and operationally.

The Cylindrichal Grit Separator/Compact Unit WS can be delivered with an integrated, automatically responding emergency bypass.

• Simple and quick installation through compact design of the entire system
• Highly efficient and scientifically proven grit separation in the typical requirements range
• The small overall height with a low inflow height and a low air injection depth in the Cylindrical Grit Separator clearly reduce the required energy demand
• Optional cables, ex works, with/without local oper operating point
• Space savings up to 50% and reduction of construction costs as opposed to conventional compact systems as well as clearly better operational accessibility
• In the case of pit arrangement with gravity inflow, no vehicle-accessible installation pit cover is required, as the disposal containers may be placed at the side of the pit
• Verifiably lowest maintenance and operating effort
• Whole system is hygiene-encapsulated and despite this, easy accessibility to all units is given
• Very easy modifiaction of the screen gap width possible according to required operating situation
• No moving parts in the submersed section of the fine screen system
• Very easy operator-friendly implementation of grease and floating particle separation
• Optional: Integrated emergency bypass line, i.e. no additional structural measures required
