Automatic laboratory filter press equipment
Filtration is the separation of a fluid-solids solution involving the passing of this mixture through
a porous barrier which retains most of the solid particulates contained in the mixture.
The various terms used in filtration processes include:
Media – the filtration cloth to collect the solids
Liquor – the solution containing the liquid and solids
Filtrate – the liquid that has been filtered clear
Cake – the solids filtered out of the liquid
Polishing – the removal of the last bit of solids for a finished liquid product
Washing – pumping water or a wash liquid over the cake
Pre-coat – coating the filter cloth with a material like diatomaceousearth to aid in the filtering
The liquor is either pushed through the filter under pressure. The types and configurations of filters vary widely;
each has its own method of filtering, its own method of discharging the filtrate and discharging the cake.
Depending on the product, sometimes the filtrate is the desired product and other time the cake is
the desired product.
Filter presses are measured by the square foot surface area available for filtering, and the cubic foot cake capacity.
Plate and Frame Filter Press
this is an assembly of plates covered with a filter cloth and frames designed to collect the cake,
held together in a press with that has a head plate and tail plate, the press is closed by a hydraulic pump,
or manually in small presses. The plates and frame can be made of many types of materials,
polypropylene is popular.
Chamber filter press
Many times the press has “recessed plates” where two plates form a cavity for collecting cake eliminating the frame.
Filter presses must be opened and the plates separated to remove the cake.
These are batch filters that push the liquor through the filter under pressure. Once the cake capacity is reached
the cake must be removed before you continue the process.
The feature / application of chamber filter press
Straight filtration of greywater possible
Fines are discharged in a compressed and semi-dry filter cake
No more extensive handling of wet sludge
Different closing options from manual to automatic are available
Applicable to reduce density in the agitator pit
Filtration of coloured water
The filtered water can be used in the production loop
To produce concrete
To treat product surface(e.g. Concrete stone, slabs, facace...)
To rinse mixer, concrete buckets...
Reduction of the water bill through
Reuse of filtered water
Eliminate charges for effluent discharge
Filtered water is kept in the loop
Reduction of the amount of waste due to reuse of the reclaimed material
Significant reduction of disposal costs
Reclaimed material is reintroduced into the production loop
Compliance with legal regulations
