Obliquely-arranged lamellar clarifier

The process water suspension accumulating in production is guided to a dirty water collection basin. This is pumped by a specially designed submersible pump to the obliquely-arranged lamellar clarifier to be clarified.

The process water flows from the production through the specially coated ECS honeycomb structure. With this honeycomb structure, the obliquely-arranged lamellar clarifier performance is 10 times greater than a conventional sedimentation tower.

The solid particles in the dirty water are separated by the physical flow process of the solid/liquid separation and sedimentation in the particle hopper. The sediment concentrated here can be dehydrated further via a bag drying station. The water cleaned in the lamellar clarifier flows over an overflow to a separately provided fresh water tank and is then returned to the process water circuit.

The obliquely-arranged lamellar clarifier is equipped with a manual cleaning function.

ECS obliquely-arranged lamellar clarifier operate without the addition of additives.

• Obliquely-arranged lamellar clarifier with specially coated lamellar packages and ECS honeycomb structure
• Clarifying performance 10 times greater than conventional sedimentation towers
• Stainless steel inlet screen
• Manual flushing function of the lamellar clarifier via valve

• Special offshore sea water coating of the clarifier
• Metering station for addition of additives

Bag drying station

The sediment concentrated in the lamellar clarifier is pumped to the upper catch basin of the bag drying station for further drainage by means of an eccentric screw pump. The fill level is monitored by a level sensor, which prevents an overflow.

The sludge runs from the catch basin through filler nozzles into the individual drying bags. Here the sludge is further dehydrated and dried. The final degree of drying can be regulated with the drying period.

The water separated by the drying bags is transported via a container into a channel and fed back into the dirty water collecting basin.

If the drying bags are filled and the desired degree of drying is achieved, the ball valves on the filler nozzles are closed. After the clamping rings are opened, the filled drying bags slide into the container and can be conveniently removed.

• Catch basin with level switch (overflow protection)
• 2 ½ inch ball valves
• Inlet nozzle and clamping plate made of PVC
• Hot-dip galvanised container
• Drainage channel for the water separated in the drying bags

Pressure boosting station

The liquid cleaned in the lamellar clarifier is brought to an operating pressure of approx. 4-6 bar by a pressure boosting station and supplied to the production machinery via pressurised water pipes.

The pressure boosting station is equipped with a check valve, manometer, pressure switch, ventilation valve and compensation tank. In addition, the pressure boosting station is monitored by a temperature sensor. In the process, it is assured that no damage occurs to the pressure boosting station in case of possible leakage in the pipeline system of the production machinery.

• Automatic pressure pump control with pressure sensor
• Regulated operating pressure
• Compensation tank to accommodate for pressure surges
• Check and ventilation valve
• Temperature monitoring with a sensor

Fresh water tank

The liquid cleaned in the lamellar clarifier is stored in the integrated freshwater tank and prepared for supply to the production machinery. The fill level is monitored continuously. Possible water losses in the circuit, e.g. due to evaporation, are automatically refilled.

• Water level monitoring with automatic feeding
• Overflow connection
