    ECS VFP/VFB – base system with high clarifying performance



Water treatment plant with obliquely-arranged lamellar clarifier, metering pump and chamber filter press or bag drying station

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. It is possible to supply flocculant as a sedimentation accelerator via an injection port.

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 via a chamber filter press or 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.

Basically, ECS VFP/VFBs can operate without the addition of flocculants. A liquid additive is added to achieve the full clarifying performance at maximum production load.

  • 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
  • Metering pump and injection port for addition of additives and sedimentation accelerators

VFP 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 water 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 pneumatic cylinder, to the container arranged below the chamber filter press.

  • Hydraulic opening and closing of the filter plates
  • Positioning sensor for plate package
  • Compressed air diaphragm pump for abrasive sludge for filling the filter plates
  • Pressure relief of the filter press via 3-way valve
  • Vibration bar with pneumatic cylinder

VFB bag drying station
The sediment concentrated in the obliquely-arranged 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 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


Submersible Pump
Submersible Pump

The automatic control of VFP water treatment plants takes place with a Siemens PLC and the control of the VFB takes place with a switchgear. Operation of the plant parameters takes place via a control panel or directly via the switchgear. The plant can be adjusted to the operational requirements with the parameter settings.

Our VFP/VFB software is developed in-house. It is based on our knowledge of process water preparation and our practical experience gathered for over 20 years.

  • Siemens PLC, including control panel / switchgear
  • Control module for metering pump
