The WWTP works on an improved SBR principle where the control unit with a microprocessor decides on the correct operation. In addition, the WWTP is equipped with an ingenious sludge removal method. Excess activated sludge removal is controlled in automatic mode. In the case of a lower load, less excess sludge is drawn off and in the case of a higher load, more is drawn off.
In this way, we can regulate the amount of sludge in the AS-iNutricut WWTP. The optimal amount of sludge is the basis for achieving high efficiency of WWTPs and for reliable achievement of nutrient removal from WWTPs. For sites with a strict regime of compliance with low concentrations of P (sites with the occurrence of eutrophication in the recipient or pond) we can supply the type of WWTP with phosphorus precipitation equipment, where the outflow parameters of phosphorus are even lower than the basic type of WWTP. In the case of the idea of using treated water for reuse, we offer sanitation of treated water using a UV lamp.
The wastewater treatment plant has a simple installation, a simple fully automatic operation without the need to ensure the demanding removal of excess sludge. Excess sludge disposal is solved by means of an integrated dewatering device, which ensures the removal and accumulation of excess sludge in a dewatered form in a separate device. The collected and dewatered sludge is used in composting. All this makes it the first intelligent WWTP in Slovakia.
Wastewater flows through the inlet basket into the primary part of the innovated SBR reactor of the wastewater treatment plant (WWTP), where the inlet is calmed and mechanical impurities are partially separated. The wastewater in the SBR reactor undergoes a purification process. The cleaning takes place in 6 phases. During the day, the phases of aeration, intermittent aeration, sedimentation, flushing, removal of treated water and sludge removal alternate. During the aeration phase, the tank is filled and aerobic cleaning processes take place at the same time. Floating microorganisms clustered into flakes remove organic pollution by aerobic degradation and transform it into CO2, H2O and also convert it into new biomass. In the sedimentation phase, when the aeration is switched off, an interface – activated sludge – purified water is created in the reactor.
Before pumping the treated water from the WWTP, the exhaust pipe is first flushed with clean water to the primary part of the WWTP. This prevents unwanted draining of insoluble substances into the effluent. The purified water is then drawn into a gutter. Excess sludge generated at the WWTP is pumped to the drainage facility at regular intervals, according to the control system, where it is stored for subsequent disposal. All 6 cleaning phases take place fully automatically using RS and the internal original AS-iNutricut design.
WWTP monitoring using AS-GSM – allows you to monitor the operation and inform the owner via
message about faults and operating conditions.
It is possible to supply the WWTP with a free-standing pillar or a wall cabinet for the blower and
the control unit.
The AS-iNutricut WWTP was certified by the renowned company TÜV SÜD.
