Scope of Application

Used in small-scale industrial wastewater treatment in livestock farming, papermaking, slaughterhouses, leather, sugar making, brewing, kitchen waste, textile, dyeing, petrochemical, and other industries, for removing suspended solids, floating substances, and sediments.

Used in industries such as papermaking, alcohol, starch, and food processing to recover fibers, residues, and other valuable substances.

Used for sludge pretreatment or river dredging.

Working Principle and Structure

The main body of the wedge wire screen solid-liquid separator is a stainless steel flat filter screen surface, precisely manufactured from wedge-shaped steel rods. The wastewater to be treated is evenly distributed onto the inclined screen surface through an overflow weir. Because the screen surface has small, smooth gaps on the front side and larger gaps on the back side, drainage is smooth and clogging is avoided. Solid materials are retained, while filtered water flows out through the screen gaps. At the same time, under hydraulic action, the solids are pushed into the spiral groove at the lower end of the screen plate. The screw conveys the solids forward to the pressing section for further dewatering. The dewatered dry residue is discharged through the outlet, thus achieving solid-liquid separation.

Widely used

The wedge wire screen solid-liquid separator effectively reduces the concentration of suspended solids in water, thereby lowering the treatment load of subsequent processes. It is also used in industrial production for solid-liquid separation and the recovery of valuable materials, making it an excellent device for filtering or recovering suspended solids, floating materials, sediments, and other solid or colloidal substances.

Note: Without installing the mixer, solids will settle at the bottom of the tank, leading to excessively high concentrations. This may overload the screen, affect machine operation, and cause malfunction. Therefore, the mixer must be installed to maintain uniform concentration for proper operation.

Frequently Asked Questions

How to choose the right filter press model based on material properties?

Selecting a filter press model depends on key material properties: particle size (to determine filter cloth mesh), viscosity (affects required pressure), corrosiveness (dictates filter plate material, e.g., PP for mild corrosion, stainless steel for strong), and solid content (influences filtration area and cycle time). High-solids materials need larger filtration areas, while abrasive materials require wear-resistant plates. Match pressure ratings to material viscosity—thicker slurries need higher pressure (1.0–2.5 MPa) for effective dewatering.

What to do if filter plates leak?

First, stop operation and check:

Filter cloths: Replace damaged or misaligned cloths that disrupt sealing.
Filter plate seals: Inspect for cracks, wear, or debris; clean seals or replace plates if damaged.
Pressure imbalance: Ensure uniform pressure across plates (adjust hydraulic system if uneven).
Plate alignment: Realign plates if shifted during operation. Test with low pressure after fixes to confirm leaks are resolved.

Do filter cloths need regular replacement? How often?

Yes, filter cloths require regular replacement as they clog, tear, or degrade over time, reducing filtration efficiency. Frequency depends on material: 4–8 weeks for abrasive/viscous materials (e.g., mining slurries); 3–6 months for less harsh materials (e.g., food-grade liquids). Signs to replace early: slower filtration, increased pressure, or visible damage (holes, fraying).

Is installation and operation training provided after purchase?

We offer installation and operation training post-purchase. This typically includes on-site installation guidance, hands-on operation training (e.g., setting parameters, troubleshooting), and documentation (manuals, video tutorials). Some provide follow-up support for 1–3 months to ensure operators master key functions, especially for automated or custom models.

If the power supply is not the issue, how to fix the machine tripping and shutting down?

Check these common causes:

Overload: Motor may be overworked (e.g., excessive slurry feed); reduce load or inspect for jammed components (e.g., filter plate movement).
Faulty sensors: Pressure or temperature sensors may trigger safety shutdowns; calibrate or replace malfunctioning sensors.
Hydraulic system issues: Low oil level or clogged filters can cause pressure spikes; check fluid levels and clean/replace filters.
Electrical connections: Loose wires in control panels may interrupt power; tighten connections and inspect for short circuits.
