Sludge Dewatering Filter Press
Filter presses are effective in extracting water from sludge. These devices function under feed pressure and can employ either concave or membrane plates to segregate substantial quantities of solids from the sludge. As the wastewater traverses the plates, the discharge mechanism and filter media capture the solid particles. The wastewater slurry persists in flowing into the system until all the water has been expelled. The residual solids consolidate into a dry cake, which is then gathered in a basin for subsequent disposal.
How does a filter press work?
Filling
During the filling phase, the press fills with slurry and distributes it evenly across the filter plates.
Filtration
As the pressure increases, the mixture is pressed against the filter cloth, separating the water from the solids.
Reaching
When the filter chamber is completely filled with filter cake, the cycle ends and can be reset.
After all the filter chamber filled with pulp, pressure filtration process begins, help feed the pulp into pulppressure pump to solidliquid separation. Since the solid particles remain in the filter cloth of the barrier
Chamber and the filtrate drainage ditch on the filter cloth along the filter plate is discharged when the filtrate no longer flows, the dehydration process is completed.At this point, you can stop feeding, the head board returned to its original position, the mobile device will filter plates filter plates have been opened. Cake rely on weight loss. This completes the pressure filtration process.

Screw filter press for sludge dewatering treatment
The sludge dewatering screw press machine for wastewater treatment developed by holly utilizes the dewatering principles of force-water homo-direction, thin-layer dewatering, proper pressure and extension of the sludge dewatering path. The new equipment, more advanced than the traditional dewatering equipment which are easily blocked, unsuitable for low-concentrated sludge and oily sludge, of high consumption and difficult to operate, well eliminate these problems and are of higher efficiency and power saving
Sludge concentration & dewatering Body; Flocculation & Conditioning Tank; Integrate Automatic Control Cabinet; Filtrate Collection Tank
Working Principle:
Force-water concurrent; Thin-layer dewatering; Moderate press; Extension of the dewatering path
It has solved several technical problems of other similar sludge dewatering equipment including belt presses, centrifuge machines, plate-and-frame filter press have, which are frequent clogging, low concentration sludge / oil sludge treatment failure, high energy consumption and complicated operation etc
Thickening: When the shaft is driven by the screw, moving rings around the shaft move up and down relatively. Most water is pressed out from the thickening zone and fall down to the filtrate tank for gravity.
Dewatering: The thickened sludge moves forward continuously from the thickening zone towards the dewatering zone. With the pitch of the screw shaft thread getting narrower and narrower, the pressure in the filter chamber increases higher and higher. In addition to the pressure generated by the back-pressure plate, the sludge is greatly pressed and dryer sludge cakes produce.
Self-cleaning: The moving rings rotates continuously up and down under the pushing of the running screw shaft while the gaps between the fixed rings and moving rings are cleaned to prevent from clogging that happens frequently for traditional dewatering equipment.
Product Feature:
Special pre-concentrating device, wide feed solids concentration: 2000mg/L-50000mg/L
The dewatering part of MSP consists of a thickening zone and a dewatering zone. In addition, a special pre-concentrating device is mounted inner the flocculation tank. Therefore, the wastewater with rather low solids content is not a problem to MSP. The applicable feed solids concentration can be as very wide as 2000mg/L-50000mg/L.
Since MSP can be used directly to concentrate and dewater the low-solid sludge from aeration tanks or secondary clarifiers, the users don't have to build a thickening tank or a storage tank any more while they have to when using other types of sludge dehydrators, especially the belt filter presses. Then significant civil engineering cost and floor area are saved.
An effluent treatment plant (ETP) is a facility designed to treat wastewater before it's released into the environment or reused. ETPs are crucial for managing wastewater from industries, sewage systems, or any source of liquid waste to prevent pollution and protect public health.
Key Components of an ETP:
Preliminary Treatment: This involves removing large solids and debris through screening and grit removal.
Primary Treatment: Here, the wastewater is allowed to settle in large tanks, separating solids from liquids. The solids, known as sludge, are removed for further treatment.
Secondary Treatment: This stage typically involves biological processes where microorganisms break down organic matter. Common methods include activated sludge systems and trickling filters.
Tertiary Treatment: This advanced treatment focuses on removing remaining impurities, including nutrients like nitrogen and phosphorus. Techniques can include filtration, chemical treatment, or advanced oxidation.
Disinfection: Before discharge or reuse, the treated water is disinfected to eliminate pathogens, often using chlorine, UV radiation, or ozone.
Sludge Management: The sludge generated during treatment is further processed, which can involve digestion, dewatering, and sometimes incineration or landfilling.
