Which types of screens are used in wastewater treatment ? 1. Coarse Screens for Wastewater Treatment Coarse screens consist of parallel rods, rods or wires, wire mesh, or perforated plates, with openings usually round or rectangular. Opening size from 6 to 150 mm (0.25 t0 6 in). Two types: Fixed Bar Screen Band Bar Screen 2. Fine Screens for Wastewater Treatment Fine screens generally adopt a sieve with a clearance of less than 6 mm. Fine screen types: Wedge wire cylinders/Drum Screen Static sieve bend screens 3. Micro Filter for Wastewater Treatment If the filtering requirements are relatively high, you need to use wastewater filter housing. Self-cleaning filters , bag filters, and cartridge filters are available. we are a high-tech enterprise dedicated to the development, design, production, and promotion of adva...

Candle filters are an alternative approach for removing fine particles. It is a closed system consisting of a pressure vessel and vertically installed spiral candles. Can be used both as a filter and as a thickener. What is the use of a candle filter?  Provide for thin-cake pressure filtration, cake washing, drying, reslurry, and automatic discharge as well as heel filtration in an enclosed pressure vessel. Some application cases are like that: 1. Filtration and drying of activated carbon and bleaching earth from vegetable oil 2. Filtration of catalysts, for example, Pd, Pt, Rh, and Raney nickel 3. Cleaning of electrolyte baths e.g. Zn and Sn and precious metals 4. Filtration of PTA wastewater (Purification Terephthalic Acid) 5. Filtration of polyols 6. Filtration of antibiotics 7. Chloralkali filtration 8. Spin bath and rinse bath filtration 9. Filtration of cellulose fibers 10. Titanium dioxide filtration 11. Metal oxide filtration e.g. iron oxide, chromium oxide, etc. 12.

With durable materials and various models, perforated tubes can filter liquids, solids and air or sieve different materials to ensure the purity. Weakening noise and granary ventilation are also their important functions. With good acid and alkali resistance, sieving tube is a very practical product for filtering ceramic powders, glass materials, plastic materials, soils, mineral aggregates, drug particles, metal powders, etc. The perforated tubes have various types based on different applications. Perforated tube often be used as the outer layer of filter cartridge. Perforated tubes also can be the inner support layer of filter element. We offer special stainless steel perforated plate for filter beds in water treatment and related technologies. Any design of perforated plate is possible and can be delivered to site within workable lead times. Sheet length and thickness: We can offer various products according to customers' requirements.
