Stainless Steel Multi-Media Water Filter System Automatic Self Cleaning Wastewater Purifier Plant

Machine filtering is to use one or several filter medium, under the pressure of certain, make through the medium, bioburden remove impurities, get filtrate, so as to achieve the purpose of filter. Inside pack packing is commonly: Quartz sand, anthracite, particle porous ceramics, manganese sand etc, user can choose according to the actual situation of use.

Machine filtering is widely applied in water treatment process, mainly used in water treatment except turbid, reverse osmosis and ion exchange soften the desalination system preamp pretreatment, also can used for surface water and groundwater except sediment. Fill turbidity requirements less than 20 degrees, effluent turbidity up to 3 degrees Celsius.

Multi-media Filter

Filtering with media filters, also known as depth filtration, is done by filtering water through a thick layer of graded particles, called the filter bed. These particles can be sand, gravel or other granular materials. The filtration degree depends on the effective size of the bedding and the water velocity through the filter. 

Basic principle: Uses the interception and filtration actions of multi-media filter materials to remove large-diameter impurity particles, colloids, and suspended solids.

Application:

Widely used for pretreatment of reverse osmosis and softeners, reclaimed water reuse, and situations requiring the removal of suspended solids and impurities from water.

Multi-media filtration can be used for domestic water pretreatment, swimming pool water treatment, peripheral water filtration system, surface water, groundwater turbidity removal, wastewater treatment, reverse osmosis, electric sea analysis, high ion exchanger, ultrafiltration and other continuous pretreatment, power generation, chemical, paper, beverage and other raw water filtration treatment. Container type shallow sand filters can be used in industrial water equipment.

The function of multi-media filter is mainly reflected in the following aspects:

1. Remove suspended impurities
The multi-media filter can effectively remove suspended impurities in water, such as mud and sand, suspended solids, colloids, and organisms such as algae. The removal of these impurities can reduce mechanical damage and contamination to subsequent equipment, such as reverse osmosis membrane elements.

2. Improve water quality
After the water is treated with a multi-media filter, the turbidity can reach below 3 degrees, which greatly improves the transparency and cleanliness of the water quality. The effluent suspended matter can be less than 5 mg/l, meeting the needs of some water treatment process.

3. Pretreatment equipment
Multi-media filters are often used in pretreatment equipment for deep seawater purification, and various filter materials can be added according to process requirements. It can be used not only on its own, but also as a pre-filtration for advanced treatment of water quality (exchange resin, electrodialysis, reverse osmosis) .

Features

1. Manual or automatic control is available;

2. Water distributor is simple, uniform and reliable;

3. Finished water collector has high strength and long service life;

4. Easy to install. Only connect the inlet and outlet to the waste pipe when installing;

5. Less water consumption in backwash: A homogeneous filter is used, so that backwash cycle is extended and the total backwash water volume is greatly reduced;

6. High backwash efficiency: An advanced water collector is used, ensuring efficient backwash effect.
