1. Industry Overview
Industry Trends
Coal-fired power plants worldwide must comply with ultra-low emission standards (e.g., SO₂ ≤35mg/m³), making efficient dewatering and recycling of desulfurization gypsum (CaSO₄·2H₂O) a critical process.
Wet limestone-gypsum desulfurization accounts for over 90% of applications, with byproduct gypsum requiring ≤10% moisture content for reuse in construction or cement industries.

Tower/vertical press filter use air or water to form a huge pressure difference on both sides of filter cloth to achieve very efficient separation of solid and liquid.
DZY vacuum press filter is a new type patent of filter press equipment, which researched and developed by our professional engineers. It adopts a special cloth as filtration medium,using both vacuum and high pressure for reducing the water content to the lowest limit. The DZY vacuum belt press is used in the industry filtration, the sludge, viscosity and fine material’s dehydration.
Our ceramic filter is widely used in separating specific minerals and waste minerals of nonferrous metal, ferrous metal, rare metal, and electrolytic residue oxide, as well as slag in chemical and environmental protection industries. It can handle materials with fineness ranging from -200 to -450 meshes, including various superfine materials.

GNZ centre drive efficient thickener is a kind of new-style solid-liquid separation equipment, and is designed by our company with the introduction of foreign advanced technology.
The SSPF smart row plate filter press is a fast opening and closing plate filter press which mainly consists of the electrical control system, hydraulic control system and the main engine.
Ceramic filter plate, also known as ceramic filter, ceramic plate and filter plate, is a new filter medium made of corundum and silicon carbide by special techniques. Our ceramic filter plates have been widely used in the filter dewatering of iron concentrate, zinc concentrate, copper concentrate, nickel concentrate, aluminum concentrate, gold concentrate, and other non-metallic concentrates and the solid-liquid separation of coal, fine chemical engineering, paper, pharmaceutical, chemical fiber, food, environmental protection and other sectors.
Toncin horizontal rubber vacuum belt filter is a new-type, high-efficiency, and continuous-operation solid-liquid separation mechanical equipment developed by our company on the basis of introducing, digesting, and absorbing technologies of similar foreign products. At the same time, it is also a kind of mechanical equipment that fully utilizes the gravity and vacuum suction to achieve solid-liquid separation. In the structure, the vacuum zone is arranged in the horizontal direction, and the length of the vacuum zone can be continuously used to complete different processes such as filtration, washing, and blotting etc. It has the advantages of high filtration effect, large production capacity, good washing effect, wide application range, simple and smooth operation and convenient maintenance etc. It is particularly suitable for filtering suspension slurry with solid coarse particles, high density and filter cakes need to wash many times. It can be widely used in solid-liquid separation in metallurgy, mining, chemical, papermaking, food, pharmaceutical and environmental protection and other industrial sectors; and it particularly has a good application in the wet flue gas desulfurization gypsum dehydration (FGD).
HVPF vertical automatic press filter is the most advanced filter that the world has ever get. Vacuum has a limit, but Pressure not. HVPF vertical automatic press filter use air or water to form a huge pressure difference on both sides of filter cloth to achieve very efficient separation of solid and liquid.

TC series ceramic vacuum filter is a new type high-effect, energy saving filtration equipment, using vacuum and ceramic plate with micro-holes for solid-liquid separation. The plate material is corundum, resisting to almost all temperatures, and has a long operation life. The micro-holes in plates only allows liquid to flow through but not air and solid. Filtrate is drawn through the ceramic plates as they are immersed into the slurry cabin, and cakes forms on the surface of the Plates.
