Our company is a complete setQuartz sand filter manufacturerAnd provide quartz sand filter tank bodies for various water treatment engineering companies, with a supply range of major cities across the country such as Shanghai, Nanjing, Guangzhou, Shenzhen, Fuzhou, Xiamen, Nanchang, Wuhan, Changsha, Beijing, Zhengzhou, Chengdu, Chongqing, as well as Southwest, Northeast and North China regions, and have freight logistics companies to provide supporting services. We are the most professional manufacturing company in Hangzhou, producing quartz sand filtersCommon filters are made of stainless steel 304 material and carbon steel material. The interior is generally treated with epoxy or lined adhesive for corrosion prevention. The water distribution system commonly includes bell mouth water distribution, basket water distribution, flat plate water distribution, dome plate water distribution, stainless steel tube water distribution, and ABS mushroom head and stainless steel cylindrical wire wound water cap water distribution.
1、 QuartzSand FilterKey features of
The quartz sand produced by our companyfilterThe equipment has a simple structure and is easy to operate for backwashing. It mainly changes the direction of water by adjusting four valves. During operation, the water flows in and out, while backwashing flows in and out. The backwashed wastewater is then discharged through the drain valve and washed through the front wash until the effluent is clear and clean. When filling quartz sand, attention should be paid to the specifications of the interception layer quartz sand, which is 0.5-1.0mm in size and above 700mm in height. There are two supporting layers below, with a loading height of 1-2mm at 150-200mm and a loading height of 2-3mm at 150-200mm. Untreated water has a sewage interception capacity of 0.5-1.0 Kg/m3, water treated with lime has a sewage interception capacity of 1.5-2.0 Kg/m3, and water treated with coagulation has a sewage interception capacity of 2.5-3.0 Kg/m3.
2、 Comparison between quartz sand filter and other filtration equipment
Quartz sand has a stronger ability to intercept pollutants compared to activated carbon, especially for removing small particles such as sediment with a higher removal rate. It is also inexpensive. On the market, one ton of quartz sand costs around 500 yuan, while one ton of activated carbon costs around 8000 yuan
Compared to fiber ball filters, quartz sand filters are mainly characterized by their ease of operation, requiring only backwashing and forward washing. On the other hand, fiber ball filters require a stirring motor in addition to backwashing and forward washing, making the operation more difficult. And quartz sand is relatively easy to backwash, while fiber balls are prone to clumping and not easy to backwash. Fiber ball regeneration requires stirring, which increases energy loss and operational costs. Additionally, fiber balls are relatively expensive, with an average price of around 50 yuan per kilogram.
IIIquartz sand filterTechnical parameters:
1. Design filtration rate: 8-12 meters/hour. When the head loss is around 5 meters, backwashing regeneration is required (usually by reading the pressure difference between the inlet and outlet at 0.05MP).
2. Anti cleaning intensity: 10-15L/second • square meter.
3. Rinse duration: 5-7 minutes
4. Inlet water pressure: ≥ 0.4Mpa backwash inlet water pressure: ≥ 0.20Mpa
5. The expansion rate is 25% -50%.
4、 Selection of packing material for quartz sand filter
Quartz sand filters and multi-media filters are widely used in water treatment. Quartz sand filter media is made from natural quartz ore as raw material, processed by crushing, washing, and sieving. It is currently the most widely used and largest amount of water purification material in the water treatment industry. It is free of impurities, resistant to compression and wear, has high mechanical strength, stable chemical properties, strong pollution interception ability, high efficiency, and long service life. It is suitable for single-layer and double-layer filtration tanks, filters, and ion exchangers, and all indicators meet the (CJ/T43-1999) standards. Processing includes refined quartz sand, pure white quartz sand, acid treatment agents, and ordinary quartz sand, which 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
5、 Scope of application of quartz sand filter:
Suitable for filtering drinking water and other water quality purification treatments, it is more suitable for the pre-treatment and circulating water treatment of production water in petroleum, chemical, mining, metallurgy, thermal power, printing and dyeing, leather making, food and other industries, as well as the recycling and utilization of sewage.
