Filter press is a machine that used for solid and liquid seperation by physical priciples under high pressure.
Hydraulic filter press for sale equipments are used various industrial solid-liquid seperation processes. With the help of filter press, dewatering applications' efficiency is higher also maintenance is cost-effective.
Filter press more effective equipment for sludge dewatering & liquid-solid seperation from belt filter press & centrifuge decanter.
A filter press works through a series of steps to achieve solid-liquid separation under high pressure levels.
Fill: The slurry or mixture of solid and liquid is pumped into the filter press. To make a homogenous mixture sludge thickeners or sludge conditioning tanks have to be used. The slurry enters the chambers formed by the filter plates and filter cloths by the help of pressure pumps. Using sludge thickener tanks allow reduction of water content inside the sludge and using sludge conditioning tanks just help for homegenous solid and liquid mixture.
Filtration: Once the slurry is in the filter press, pressure is applied to the system. This pressure can be generated mechanically or hydraulically. As the pressure increases, the liquid portion of the slurry is forced to pass through the filtering medium, leaving the solid particles behind.
Cake Formation: The solid particles accumulate on the filter medium, forming a layer known as the filter cake. The filter cake continues to build up as more liquid is forced out.
Cake Removal: Once the filtration is complete, the filter press needs to be emptied. This involves removing the solid filter cake from the filter plates. Some filter presses have automatic cake removal mechanisms, while others require manforce to empty intervention. The discharged filter cake can be further processed or disposed of as needed.
Finally cycle begins again.
In mining industry high solid level of dewatered sludge is preferable because of the transportation costs. Filter press equipment can achive the best solid ratio in his sludge cakes. Gold mines, copper concentrate, silver mining, nickel concantre and others can be good candidates for filter press dewatering.
Edible oil or mineral oil filtration processes are widely common types.
In oil filtering process, frame & plate filter press is the main part of the system. After increase of temperature of oil, clay added to oil sample and mixed. This oil and clay mixed liquid is pumped to filter press machine which has frame&plate type plates and covered cotton filter press clothes with filter paper.

After this filtration process, filtered output is taken, then dewatered sludge filled filter press removed from this sludge.
High purity petrolium industry good can be achieved by our special desing filter press.
All the wet surfaces of zinc-phosphate filter press are covered with AISI 316L stainless steel or polypropylene for acidity resistance. Piping is done by polyethylene or stainless steel pipes. Galvanize, coating baths and electrostatic application of powdered paint industries especially sludge removal for zinc-phosphate baths. Also used for purification of acidic products.
This product has high pressure resistance up to 16 bar to get the lowest moisture content in the ceramic clay cake from filter press equipment. According to our customer's desires we can manufacture it by using special desing round filter plates or chamber filter plates for kaolin filter press.
Marble or stone minings require huge amount of clean water to performe. Our filter press products towards to mining industry are desing to filter and treatment of used water originating from stone cutting process.
Our food industry filter press has AISI 316L covered liquid contact surfaces. Side channels and inlet pipes also made from AISI 316 stainless steel. It is applicable for sugar syrups, wine making, brewery industry, yeast production etc. Especially sediment of wine and beer products can not be filtered from paper filters. To collect huge amount of sediment in wine and brewery products chamber type filter press can be used efficiently.
Our specially designed liquid fertilizer filter press machine can be used as liquid fertilizer purifier to prevent clogging troubles pivot irrigation systems. This helps sedimentation of particles in the package of liquid fertilizer also prevents clogging problems of pumping for irrigation systems.
High purity chemical production is provided by using our specific chemical filter press which used special filter cloths and filter papers.
Types of hydraulic filter press according to plate type;
* Plate and Frame Filter Presses
* Recessed (Chamber) Plate Filter Press
* Recessed + Membrane Filter Press
