Single-bag Filter

It is a new type of filtration system. Inside the filter, a metal mesh basket supports the filter bag. Liquid enters through the inlet, passes through the filter bag, and exits via the outlet, while impurities are retained inside the bag. After replacing the filter bag, the unit can be reused.

Applications

Paints, beer, vegetable oils, pharmaceuticals, chemicals, petroleum products, textile chemicals, photographic chemicals, electroplating solutions, milk, mineral water, hot solvents, latex, industrial water, sugar solutions, resins, inks, industrial wastewater, fruit juices, edible oils, waxes, etc.

Key Features and Advantages

Convenient and quick

Bag filters feature large handling capacity, compact size, and high dirt-holding capability. Based on its working principle and structure, bag replacement is convenient and quick.

Flexible in use

Bag filters are widely applicable, flexible in use, and available in a variety of installation types

No cleaning

The filter requires no cleaning, saving labor and time.
The probability of side leakage from the filter bag is very low, effectively ensuring filtration quality.

Low pressure loss

Bag filters can withstand higher operating pressures, have low pressure loss, low operating cost, and significant energy-saving benefits. The filtration accuracy of filter bags continues to improve, currently reaching as fine as 0.5 μm.

Frequently Asked Questions

Our popular products include: vehicle-mounted sludge solidification units, diaphragm filter presses, sludge dewatering machines, as well as engineering design and installation services for municipal sludge and sand-washing sludge treatment.

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.
