Design

A mobile stand supports the dosing and mixing vessel including a hinged lid and an agitator with geared motor and an infinitely variable dosing pump designed as a piston diaphragm pump with an upstream diaphragm. The agitator gear unit with a magnetic rotary field drive allows the vessel to be opened and filled operation.
The mixing vessel and all supporting parts and parts coming into contact with product are made of stainless steel.
Larger systems available on request, including as stationary versions.

Mode of operation

Depending on the size of the doing vessel, the appropriate quantity of kieselguhr is prepared with liquid to be filtered in the agitator vessel. The adjustable doing pump delivers the batch of flow of kieselguhr to the mixing tube, which is used to convey the flow of liquid to the filter.Adjustment of the dosing pump capacity depends on the degree of turbidity of the product to be filtered and/or the volume of the precoated filter.
The doing unit is connected in the inlet between the pump and filter (see diagram). Operting at a high capacity at the start of filtration, the dosing pump ensures fast build-up of the precoat in the kieselguhr filter, with the filter initially being run in the cycle. As soon as the run-off becomes clear, the system switches to the filtrate vessel, and the capacity of the dosing pump can be reduced.
