Porcelain sand filter is our porcelain sand filter in the original basis of jointly developed a new type of filter, it has a large surface area, interception capability, high water production, water quality and stability, and long filter cycles characteristics. To meet the various components of complex industrial wastewater and municipal wastewater advanced treatment. Shortcomings of traditional media and new media development in accordance with national experience, the use of high-quality kaolin, binder, pore-forming agents, anti-corrosive, etc. made by high temperature calcination, the appearance of white, hard, uniform particles, porous well-developed porosity.
the filter is widely used in: chemical, petroleum, electricity, medicine, electroplating, paper making, brewing and other industries, with different properties in different sewage, water, industrial water treatment.
has the following advantages:
1. Initial porcelain sand filter head loss, filter for the extension of the work cycle is very beneficial to terminate the porcelain sand filter head loss, can reduce the filter height, save infrastructure costs.
2. Porcelain sand interception capacity, usually in the 9-10kg / m or less, about the amount of quartz sand filter interception (7.8-9kg / m 3 ) of 1.2 to 15 times.
3. Porcelain sand is spherical surface, easy to clean, quartz sand backwash water consumption than the lower 30 ~ 50%
4. Porcelain sand strength, wear a small amount of quartz sand generally higher than 5 times longer life than
5. Porcelain sand evenly structured, easy loading, easy loss, no secondary pollution, adapted to the ion exchange, mechanical filter, no valve filter, reverse osmosis processing equipment to do pre-filter or resin supporting layer, can be used for activated carbon absorber cushion.
6. According to water quality, the special treatment, can be done in addition to iron, manganese, fluorine and other multi-purpose ceramic sand filter, wastewater treatment and as a coarse-grained oil filter, biological filter media biological filter to remove iron, manganese, fluorine, oil and other organic pollutants.
