ROTAMAT® Perforated Plate Screen RPPS |

Separation of solids from wastewater
Compaction and washing of separated screenings |
|
|
This Perforated Plate Screen (RPPS) performs screening, washing, conveying, compaction and dewatering of solids in a single unit (see also ROTAMAT® Wedge Section Screen Ro 2). Depending on the perforation diameter (1/8” or 1/4”) and drum diameter (up to 9’-10”) flows of up to 25 MGD can be treated with a single screen.
The HUBER Perforated Plate Screen is completely made of stainless steel and passivated in a pickling bath. It can be installed directly into a channel or in a separate container. Its single pass design guarantees easy cleaning and low head loss.
The HUBER Perforated Plate Screen is installed in a channel or container with an inclination of 35°. Wastewater flows into the plate screen through its open front end and out through the perforations of the screening drum. Floating and suspended materials larger than the perforations are effectively retained. The head loss increases as more and more screenings are retained in the screening drum. When the upstream water level reaches a certain height, the drum begins to rotate. Cleaned perforations are rotated into the flow and retained screenings are rotated out of the flow. Any screenings that are not flushed by spray water into a collection trough are removed by a nylon scrubbing brush.

In order to optimize the treatment process, the integrated screenings washing contributes to an improvement of the carbon - nitrogen ratio. Furthermore it helps saving costs in a decisive way.
By means of the ROTAMAT principle it is possible to integrate the screenings washing directly into the hopper and/or the lower part of the rising pipe. Here the soluble components are separated by the inertance material. Thereby the faeces are almost completely washed out and a considerable reduction in weight can be reached.
- best quality for low price
- optional equipment can be fitted without problems
- minimum disposal costs
- improved conditions concerning operation and hygiene
- almost complete washing out of faeces
- reduction in weight by about 50 %
