Obliquely-arranged lamellar clarifier:

The process water suspension accumulating in production is guided to a dirty water collection basin. An automated compressed air flushing program guarantees that the suspension remains homogeneous and the solid particles do not sediment in the collecting basin. The process water suspension 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 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 chamber filter press. The water cleaned in the lamellar clarifier flows over an overflow to the fresh water tank and is returned to the production circuit. The obliquely-arranged lamellar clarifier is equipped with an automatic flushing function and can be operated in the flow process 24h per day, 7 days per week. ECS obliquely-arranged lamellar clarifier operate without the addition of additives.

Technology:

• 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
• Fully-automatic switching between day and night operation, incl. follow-up time
• Integrated night operation flushing program for clarifier and lamellar packages
• Flushing program for process water collecting basin

Optional:

• Special offshore sea water coating of the clarifier
• Metering station for addition of additives
• Obliquely-arranged lamellar clarifier flow monitor

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 lines.

An optional frequency-controlled pressure boosting station is available. This offers the advantage of consistent water pressure with a wide range of fresh water intake volumes.

Technology:

• 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

Options:

• Regulated pressure control with a frequency converter for consistent pressure with variable intake volumes
• Redundantly installed backup pressure pump

Chamber filter press

The sediment concentrated in the lamellar clarifier is pumped to the chamber filter press by means for further drainage by means of a diaphragm pump. The filtrate water drains through a droplet channel and is returned to the production circuit. The degree of drying of the filter cakes can be individually adjusted and is monitored by a pressure sensor.

If the setting for the degree of drying of the filter cakes is reached, the pressure in the chamber filter press is released through a relief valve and the filter press opens. The filter cakes fall, with the assistance of automatic shaking by means of a gear motor and vibrating shaft, to the container arranged below the chamber filter press.

The chamber filter press adjusts independently to varying volumes of sludge due to automatic sludge detection. As a result, manual adjustment of the press with a varying production load is not necessary.

Technology::

• Hydraulic opening and closing of the filter plates
• Positioning sensor for plate package
• Hydraulic system pressure make-up via pressure sensor of up to 250 bar
• Compressed air diaphragm pump for abrasive sludge for filling the filter plates
• Fully automatic flushing of the diaphragm pump and lines with fresh water after each press cycle
• Pressure relief of the filter press via pneumatic valve
• Vibrating shaft with gear motor and position sensor
• Fully automatic sludge detection via pressure sensor and control

Optional:

• Drip tray, including automatic opening and closing via pneumatic system
• Automatic core wash-out of the filter plates
• Automatic cleaning of the filter plates by means of spray bar and high-pressure nozzles
• Designed as a completely closed system, incl. Macralon viewing hood

Fresh water tank

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

The pH and salt value monitoring with water submersion system is optionally available.

Technology:

• Water level monitoring with automatic feeding
• Auxiliary flange for connection of backup pressure pumps
• Overflow connection

Optional:

• pH value monitoring
• Conductance monitoring
• Automatic water submersion system
