Shallow sand automatic backwash filter

Product Introduction

Shallow sand filter, mainly used in industrial areas of circulating water, feed water, and wastewater filtration. HGBMF's medium filtration system utilizes deep media to effectively remove particulate matter and reduce turbidity. If loaded with a specific filter material, such as activated carbon, zeolite, can also adsorb the corresponding organic matter, ions and so on. The fluidization device in the system (bottom drainage device) can fluidize the filter medium, remove the pollutants trapped in the medium, and discharge them, and get a thorough cleaning.

Product Features

1, small size, easy to install, save space. Can be installed outdoors, no need to build, save the cost of civil construction, covers a small area, indoor and outdoor installation, can also be layered installation, strong adaptability; Compact structure, space saving, good anti-corrosion performance, indoor and outdoor installation.

2. The equipment has good anti-corrosion performance and long service life.

3, filter water, filter effect is good, filter flow rate is fast, the normal filter speed can be about 40m/h, according to the water quality can reach 60m/h; Filter backwash using product water, and do not have booster pump and backwash pump; The backwashing time is 2-3min, and the backwashing water is less than 3m3. High filtration accuracy, impurity filtration accuracy can be less than 0.10mm, effluent turbidity can be less than 0.5NTU. The filtration system consists of a standard unit sand cylinder, and the filtration flow rate can be increased from 30.6 m3 / h to 2500 m3 / h.

4. Automatic backwashing: The backwashing of the equipment is automatically identified and controlled by the intelligent control system without manual intervention. Even if the suspended matter in the water fluctuates, the equipment may automatically adapt to it.

5. Uninterrupted water supply; When the equipment is backwashed, the filtration process is carried out at the same time, and the system provides water as usual.

6, the use of unique cloth, water collection device, because of the filter system's unique water distribution system and the uniform water collector makes the water flow in the whole filtration process is layered flow, filter sand bed plane in the filtration process is always smooth, the water quality is stable.

7, the use of refined quartz sand or garnet as the filter medium, according to the water quality to choose, filter particle size can be 0.16mm homogeneous filter material 8. Long-term operation cost is low, save electricity, water and maintenance costs. Power saving: The system has a unique automatic backwashing valve, the backwashing of the sand filter tank is not carried out simultaneously, but under the normal operation of the system, it takes turns to backwash one by one, there is no need to consider the setting of backwashing water pump. At the same time, compared with other sand filtration equipment, the lift of the filter pump required is 6-7m lower.

8, save water: the system because of its unique hydrator and water collector, unified specifications tank, so that the backwashing does not need compressed air to make the medium layer of uniform expansion for effective backwashing. Backwash water used is filtered clean water, so the consumption of backwash water is small. The backwashing water of a single tank is only 1m3/ min, and the backwashing time is 2-3 minutes.

9, save maintenance costs, the whole system has no mechanical or electric valve, only rely on the unique multi-function valve to control the backwash system. Due to the unique multi-function valve no wear, long life, no damage record in 10 years, low management costs.

Application Industry

1, industrial water filtration - there are certain system requirements for water quality. Such as: steel oxygen gun water, boiler, heat exchanger water filtration, can filter out the impurities in the water, to avoid the blockage of the pipeline and nozzle.

2, industrial circulating water filtration system.

3, raw water treatment - surface river water, lake water, sea water, reservoir water, well water and urban tap water as a source of urban small quality water supply filtration, remove the sand in the water, suspended matter, algae, organic matter and so on.

4, agricultural irrigation - especially suitable for high flow, good impurity content of water sources, such as irrigation irrigation, parks and golf courses on the lawn irrigation.

5, food processing industrial water, paper industry, power plant industrial circulating water treatment, industrial and medical treatment of purified water. Industrial production water recycling, industrial waste water treatment.

6. Aquaculture, swimming and water parks.
