Stainless steel filter mesh bag is a filter element inside the bag filter. Used to filter suspended matter, impurities, chemical residues in sewage residues, etc., play a role in purifying water quality to meet discharge standards.
In the leather production process, to go through degreasing, de-ashing, tanning, dyeing grease and other processes, in these processes to use a variety of chemical materials, so tannery wastewater contains a lot of organic pollutants, but also contains a lot of difficult to degrade substances such as tannin, high color, Tannery wastewater has the characteristics of large amount of water, large fluctuation of water quality and quantity, high pollution load, high alkalinity, high chroma, high suspended matter content, good biodegradability and so on, and has a definite toxicity. If the tannery waste water is discharged directly, it will cause pollution to the environment, how to efficiently treat the tannery waste water?
The harm of tannery wastewater
(1) The color of leather wastewater is large, if it is discharged directly without treatment, it will bring abnormal color to the surface water and affect the water quality.
(2) Overall leather wastewater. The upper part is alkaline, and without treatment, it will affect the pH value of surface water and crop growth.
(3) The high content of suspended matter, without treatment and direct discharge, these solid suspended matter may block the pump, drainage pipe and drainage ditch. In addition, a large number of organic matter and oil will also increase the oxygen consumption of surface water, causing water pollution and endangering the survival of aquatic organisms.
(4) Sulfur-containing waste liquid is easy to produce H2S gas when encountering acid, and sulfur-containing sludge will also release H2S gas under anaerobic conditions, which will affect water and water People can be very harmful.
(5) High chloride content will cause harm to the human body, sulfate content of more than 100 mg/L will make the water taste bitter, easy to produce after drinking diarrhea.
(6) Chromium ions in leather wastewater mainly exist in the form of Cr3+, although the direct harm to the human body is less than Cr6+, but it can be in the environment or produce savings in animals and plants, which can have a long-term impact on human health.
The stainless steel filter net bag inside the bag filter has a novel structure, small size, simple and flexible operation, energy saving and high performance
Multi-purpose filtration equipment with high efficiency, airtight operation and strong applicability. Bag filter is a new type of filter system. liquid
Flow into the inlet, filtered through the filter bag from the outlet, the impurities are blocked in the filter bag, can continue to use after replacing the filter bag.
Stainless steel filter mesh bag has the following characteristics:
1) High temperature resistance: the highest temperature can withstand about 480.
2) Simple cleaning: The single-layer filter material has the characteristics of simple cleaning, especially suitable for backwashing.
3) Corrosion resistance: stainless steel raw materials themselves have ultra-high corrosion resistance and wear resistance.
4) High strength: high-quality materials have high pressure resistance and can withstand greater working intensity.
5) Easy processing: high-quality materials can be well completed in cutting, bending, stretching, welding and other procedures.
6) The filtration effect is very stable: high-quality raw materials are selected in the production process, so that they are not used in the process easy to deform.
Stainless steel filter bag inquiry notice:
When consulting the price of stainless steel filter bag, please provide the following parameters: material, overall size, tolerance range, purchase number, mesh number, with the above data can calculate the price.
