Pumps
The sewage pumping station with separation of solids is equipped with alternately operating FZ pumps with a highly efficient hydraulic system and a reliable drive transmission system. The wastewater pumping stations manufactured by Hydro-Vacuum S.A. can use pumps with channel impellers with high-efficiency electric motors in the IP68 version (the motor can operate in dry and submerged conditions). FZ pumps are equipped with protection in the form of built-in thermal and humidity sensors. The multitude of available types and sizes of FZ pumps allows for the optimal selection of pumps to suit the investment conditions and the customer's needs.Module and fittings
Retention module of the wastewater pumping station with separation of solids, solids separators and all elements of the piping are made of stainless steel with high corrosion resistance. Other elements of hydraulic equipment, i.e. non-return valves and shut-off valves are also made of materials intended for use in sanitary sewage. The design of the sewage pumping station uses non-return valves to ensure reliable operation and effective transport of wastewater containing solids. These valves comply with applicable requirements and have the CE marking for compliance with the PN-EN 12050-4 standard. It is possible to equip the pumping station module with an additional mixing pump to prevent deposition of minor, easily sedimentable particles at the bottom of the retention module and their efficient pumping out to the discharge collection pipeline. The pumping station with separation of solids may be additionally equipped with a sewage aeration system and/or installation for dosing chemicals (coagulants) to reduce anaerobic processes and neutralization of toxic substances generated in sanitary sewage.Control
Certificates
The TSC sewage pumping station with separation of solids has a Declaration of Performance and CE marking for compliance with the harmonized standard PN-EN 12050-1:2002. This standard applies only to wastewater pumping stations with separation of solids intended for discharging sewage from places in buildings and their surroundings, located below the flood level to protect buildings and their surroundings against reverse flow. For all other applications and locations of wastewater pumping stations with separation of solids, national regulations arising from the Act on Construction Products dated 16 April 2004 shall apply Therefore, the TSC wastewater pumping station with separation of solids also has a National Declaration of Performance and marking with a construction sign for compliance with the National TechnicalPumping stations equipped with two-channel tilt flap separators
Principle of operation
In a classic (wet) pumping station, wastewater fed by gravity sewer flows directly into a retention tank. In pumping stations with solids separation, wastewater flows into a pumping tank located in a dry chamber, and is then distributed to individual separators. From the separators, the treated wastewater devoid of solids, sludge and trailing elements flows by gravity through the hydraulic elements of the pumps into the pumping station tank. When any of the pumps is running, the wastewater flows only to the separator connected to the non-working pump. The set sewage levels in the compressor station tank are controlled by means of an ultrasonic meter (other types of sensors can be used as an option). After receiving a signal that the set sewage levels in the tank have been reached, the protection-control device starts or stops the relevant pumps. The activated pump sucks the treated sewage and forces it into the separator located in the axis of the pump's discharge port. The energy of the pumped wastewater stream entrains the solids in the separator, directing them into the pumping station's discharge pipeline. The overpressure created during pumping closes the wastewater return flow to the pumping station tank. During the pump cycle, wastewater flows into the tank through the second separator and the hydraulic system of the non-working pump. When the lower preset level of wastewater in the tank is reached, the pump is automatically turned off. The design of the separator (a system of specially shaped rod basket) means that the pumping station can operate continuously without requiring additional operations to remove accumulated pollutants. During each pump start-up the separator is "self-cleaning". The hydraulic system of the pumps, which does not have direct contact with solids, and in particular with dragged solids, is not exposed to clogging.Filling stage
