Filter press; It is a filtration system that separates the solid materials in the waste water caused by domestic, industrial wastewater treatment plants and other production processes, routinely removing them and separating the solid-liquid through cloths. In the filter press system, wastewater is pressed into the system with a certain pressure and power. Thus, it allows solid materials to be held.
It is aimed to protect the system and water quality by removing solid materials such as sand and sludge formed in wastewater treatment plants with filter press. Also known as a sludge treatment mechanism or dewatering machine, the purpose of filter presses is to reduce the amount of water in solids. During this process, chemicals are added to the sludge. Thanks to this substance, the amount of water contained in the sludge is reduced. The volume of sludge with an increased solids content decrease.
The usage areas of filter presses are quite wide. This purification mechanism is preferred in environmental engineering and fabrication.
What Does a Filter Press Do?
Filter press equipment is known for its use for sludge dewatering in wastewater treatment plants. It is also used by many factories. Waste factory water and industrial materials can be separated by filter press. The benefits of using filter presses can be listed as follows.
- The benefit of filter presses is great in biochemical waste treatment systems.
- Filter presses are used for separating and refining the minerals extracted in mining operations.
- Filter presses are preferred in paint factories in order to obtain the right mixture by adjusting the paint ratio.
- Filter presses are used in the pharmaceutical industry where chemical substances need to be separated and proportioned.
- Filter presses are also preferred in the paper and recycling sector.
What are the Advantages of Filter Press?
The advantages of filter presses are as follows.
- High dewatering rate
- Option to resist acidic and alkaline liquids
- Easy service and maintenance
- Low initial investment and operating cost
- Ease of selection by sector
What are the Filter Press Types?
Filter press is divided into 3 according to the plate working feature. Filter press types: There are 3 types as manual, semi-automatic and fully automatic.
Automatic Filter Press: These are systems in which plate transport or cake unloading processes are automatically controlled from the electrical panel.
Semi-Automatic Filter Press: Machines in which the plates are manually transported by the operator, while the hydraulic piston is driven by electric motors.
Manual Filter Press: Both the hydraulic piston and plate transportation are performed through the operator.
Filter presses are classified into closed discharge and open discharge according to their filtrate outlet characteristics.
Closed Discharge Filter Press: The liquid outlet is not observable from the outside.
Open Discharge Filter Press: The liquid flows to the foot-mounted side channels through the taps located on the right and left sides of the plates.
