Ceramic Disc Filter
The ceramic disc filter is not a single filtering component, but an integrated solid-liquid separation system, which can adapt to the material properties, processing capacity and discharge requirements of different industries. Its core advantage lies in the modular design, enabling flexible combination according to scenarios. Meanwhile, it integrates functions such as online backwashing, automatic slag discharge and intelligent detection, eliminating the need for additional auxiliary equipment. It can directly connect to the production process, address the pain points of traditional filtering equipment, and achieve closed-loop operation from raw material processing to up-to-standard discharge of wastewater/slag or resource recovery.

Core Advantage Analysis
1. Superior Filtration Performance
High Filtration Precision: Capable of capturing micron-sized particles, with the solid content of the filtrate less than 50 ppm. The filtrate is clear and transparent, and can be directly reused.
Low Filter Cake Moisture Content: Reduced to below 12%, which is 3–5% lower than that of traditional equipment, significantly cutting down subsequent drying costs.
Strong Processing Capacity: The daily processing capacity of a single unit can reach 200 tons, with a unit area throughput of 1.2 tons/m²·h, improving efficiency by 3 times.
2. Outstanding Energy-saving Performance
Driven by vacuum negative pressure, it eliminates the need for high-pressure pumps, reducing energy consumption by 40%–90% compared with traditional equipment.
A single unit can save more than 100,000 kWh of electricity annually, leading to a substantial reduction in operational costs.
The ceramic filter plates feature water-permeable yet air-impermeable properties, which effectively cut down air consumption and further enhance energy efficiency.
3. Ultra-long Service Life
The ceramic filter plates boast a hardness rating of Grade 9, with acid and alkali corrosion resistance three times higher than that of metal aluminum plates, ensuring an extended service life.
Eliminating the need for filter cloths, it saves both consumable costs and labor expenses associated with replacements.
Featuring a simplified structure and low failure rate, it reduces maintenance costs by over 70%.
4. Outstanding Economic Benefits
A 3% reduction in filter cake moisture content translates to annual savings in transportation costs and transit loss expenses.
Lower moisture content and higher grade of concentrate products boost market competitiveness.
Reuse of filtrate cuts down wastewater treatment expenditure, delivering distinct advantages for long-term operations.
5. Green Sustainability
The solid content of the filtrate is less than 50 ppm, which meets discharge standards and can be recycled, facilitating the achievement of zero-emission goals.
The volume of sludge is reduced, lowering the risk of secondary pollution.
Significant reduction in energy consumption aligns with national energy conservation and emission reduction policies.
