Mode of operation The sewage treatment plant consists of a spiral filter, the buffer tank, the SBR reactor and the sludge storage tank. In the first stage, domestic waste water flows through the spiral filter, where solid matter > 3mm is filtered out of the water. The pretreated water then flows into the buffer tank. The SBR sewage treatment plant works in impound mode. First, the intake water is stored in the buffer tank. It is then pumped into the SBR reactor. Here, the waste water is treated in the following five phases. 1. Filling: the SBR Reactor is filled with waste water from the buffer tank. 2. Aeration: a diaphragm pipe aerator blows oxygen into the water. This creates activated sludge which consists of microorganisms and bacteria. In this phase, impurities in the waste water are biologically decomposed. 3. Settling phase: during the settling phase, the water is no longer aerated. The activated sludge settles on the tank floor due to the cessation of turbulence. Since the sludge settles completely on the tank floor, the upper part of the clarified water is of extremely good quality. 4. Clarified water removal: in this phase, the clarified water is pumped out using the clarified water pump. 5. Excess sludge removal: since new activated sludge is formed during every aeration process, excess sludge is pumped to the sludge storage tank during this phase so that the reactor always contains the optimum amount of sludge.

Benefits

· System proposal · Technical dimensioning · Construction & implementation plans · Mechanical system installation · Commissioning · Technical training · Technical documentation

· high purification performance · robust engineering · simple installation · easy to maintain and to repair · electronic fault reporting · remote monitoring · refitting existing tanks possible

Range

Scope of application

We offer the CLEAR WATER sewage treatment plant in construction sizes from 50 PE to 5.000 PE. The following system variants are available: · ring construction in concrete · compact construction in concrete or synthetics · rectangular construction in concrete · container construction in stainless steel. If the customer already has a tank or wishes to construct one himself, we can supply the necessary technical equipment.

The Clear Water waste water treatment system is dimensioned according to the purification performance required. A sewage treatment calculation for this is provided. We propose the following treatment stages for you: · C-elimination · Nitri-/ denitrification · Desinfection The functioning of the waste water treatment system is assured even during high load fluctuations, because the height adjustability of the pumps make it possible to adapt the volumetric loading to the actual loading at all times.
