Separator for Light Liquids
The system is designed to separate light liquids from rainwater runoff from parking lots, storage areas, gas stations, car washes, heavily soiled trucks, agricultural vehicles, etc. It can be installed on both pedestrian and vehicular areas. Wastewater must not be discharged into the separator. Hydraulic load Qmax = 6–300 l/s. Residual concentration C10–C40L < 5.0 mg/l.
How It Works
Oil-contaminated water flows into the sedimentation zone and then into the coalescence zone, where it is simultaneously demulsified and the flow direction is regulated. Solids and suspended solids settle in the sedimentation zone. The oil rises to the surface and is carried away by the water exiting the separation zone over the overflow edge. The oil separated by gravity collects on the surface of the collection sump behind the coalescence zone.
At maximum hydraulic load, the water level in the oil separator rises above the overflow edge. The treated water then flows by gravity through the relief channel below the baffle wall, over the relief overflow into the outlet shaft, and into the collection tank. Oil-containing substances remain on the surface of the sedimentation zone. Once the liquid level has dropped again, the light liquids flow to the coalescence zone.
Pumping Stations – Central
The shaft is designed for pumping wastewater and stormwater. It is ideally suited for connection to an elevated gravity sewer system. The watertight shaft is equipped with a gravity inlet and a pressure outlet. Pumping is controlled by pumps activated via a float switch, an electrode, or an ultrasonic sensor.
Construction solution
The tanks are made of reinforced concrete B30V8 or B45V8, corresponding to class C35/45 according to ČSN EN 206-1. The manufacturer guarantees the watertightness of the tanks with a watertightness certificate. If required, the tanks are fitted with penetrations for the inlet pipe prior to concreting. The pressure pipe must additionally be sealed either with a mechanical seal or with ERGELIT mortar mix.
The tanks are equipped with reinforced concrete cover plates featuring a seat to prevent horizontal displacement and a locking mechanism to ensure sealing between the tank and the cover plate. The cover plates are designed for load class D 400. They feature openings for the pumps and access to the shaft. (The number and shape of the access openings may vary depending on the design.) The shafts themselves can also be manufactured in other material versions, e.g., from double-walled PP for on-site concrete pouring.
Technical Design
The shaft is equipped with pumps that meet the parameters specified in the project documentation. The pumps are mounted on guide rods and are moved by a stainless steel chain or cable. A cast iron check valve on the discharge line prevents backflow from the sewage system when the pump is not in operation. In addition, cast iron gate valves and, in accordance with the project documentation, other fittings (flushing connection, flow meter, etc.) are installed. The pumps are controlled via an electrical control cabinet mounted on a frame (plastic, galvanized), a brick pillar, or on the facade.
Control takes place in the shaft via four float switches. The lower float at the emergency shutdown level shuts off the pump. The middle floats ensure the normal switching on and off of the pumps, and the upper float determines the emergency shutdown level. The control cabinet features a button for manually pumping out the wastewater outside of automatic operation (possible at any time). This control system may be replaced by another proven method based on the experience of local operators.
