Our company is a complete set of quartz sand filter manufacturers and supporting quartz sand filter tanks for various water treatment engineering companies. The scope of supply is major cities in China such as Shanghai, Nanjing, Guangzhou, Shenzhen, Fuzhou, Xiamen, Nanchang, Wuhan, Changsha, Beijing, Zhengzhou, Chengdu, Chongqing, Southwest, Northeast and North China, etc., and supporting services of freight logistics companies. We are the most professional manufacturing company. The common filters for the quartz sand filters produced by the company are stainless steel 304 and carbon steel. Generally, the interior is epoxy or rubber-lined anticorrosive treatment. There is a bell mouth cloth for water distribution on the water distribution system. Water, hanging basket water, flat cloth water, dome-shaped plate cloth water, stainless steel tube water cloth, water cloth water cap with ABS mushroom head and stainless steel cylindrical wire wound water cloth water.
First, the main features of quartz sand filter <br The quartz sand filter equipment produced by our company has a simple structure and is convenient for running backwashing. It is mainly through adjusting 4 valves to change the direction of the water. The backwash is down and up, and then the backwashed sewage is discharged through the drain valve, and then the front wash is carried out until the effluent is clear and clean. Pay attention to the quartz sand filling: the size of the quartz sand of the interception layer is 0.5-1.0mm The height is more than 700mm, and there are 2 supporting layers below, respectively 1-2mm loading height is 150-200mm, 2-3mm loading height is 150-200mm. The untreated water has a sewage interception capacity of 0.5-1.0 Kg / m3, the lime-treated water has an sewage interception capacity of 1.5-2.0 Kg / m3, and the coagulation-treated water has an sewage interception capacity of 2.5- 3.0 Kg / m3.
Second, the comparison of quartz sand filter and other filtering equipment. <br /> Quartz sand is relatively activated carbon. It has a strong ability to intercept pollutants, especially for the removal of fine particles such as sand and sand. The price is low. One ton of quartz on the market The sand is about 500 yuan, and one ton of activated carbon requires about 8,000 yuan. The quartz sand filter is relatively easy to use with a fiber ball filter. It is mainly manifested in the convenient operation of quartz sand, which only requires backwashing and forward washing. In addition to backwashing and forward washing, the stirring motor needs to be stirred, which is relatively difficult to operate. And quartz sand is relatively easy to backwash, while the fiber ball is easy to agglomerate and difficult to backwash. Fiber ball regeneration requires agitation, which increases the loss of electrical energy and raises the operating cost. Moreover, the price of fiber balls is more expensive, and the average price per kilogram is about 50 yuan.
Technical parameters of quartz sand filter:
1. Designed filtration speed: 8-12m / h When the head loss is around 5m, backwash regeneration is required (generally by reading the pressure difference between the inlet and outlet ports at 0.05MP).
2. Backwashing intensity: 10-15L / s • m2.
3. Rinse duration: 5-7 minutes
4. Inlet water pressure: ≥0.4Mpa Backwash water pressure: ≥0.20Mpa
5. The expansion rate is 25% -50%.
Fourth, the choice of quartz sand filter fillers <br /> Quartz sand filters and multi-media filters are widely used in water treatment. Quartz sand filters are made of natural quartz ore as raw materials, and are processed by crushing, washing and fine sieving. It is currently the most widely used and largest amount of water purification material in the water treatment industry. It has no impurities, compression resistance and abrasion resistance, high mechanical strength, stable chemical properties, strong pollution interception ability, high efficiency, and long service life. In the double-layer, double-layer filter pool, filter and ion exchanger, all indexes have reached (CJ / T43-1999) standard. Processing of refined quartz sand, pure white quartz sand, acid treatment agent, ordinary quartz sand, can meet the needs of different users.
Common specifications: 0.5-1.0mm 0.6-1.2mm 1-2mm 2-4mm 4-8mm 8-16mm 16-32mm
Five, the scope of application of quartz sand filter:
Suitable for domestic drinking water filtration and other water quality purification treatment, more suitable for the preliminary treatment and circulating water treatment of production water such as petroleum, chemical industry, mining, metallurgy, thermal power, printing and dyeing, tanning, food, and sewage recycling.
