Mechancial filter
Multimedia filter to make one or several filter media makes water of high turbidity flow through agranular or nongranular material of a certain thickness under a certain pressure, thereby effectively removing suspended impurities in the water and clarifying the water. The commonly used filter materials including quartz sand, anthracite and manganese sand, etc. they are mainly used for turbidity removal of water treatment, water softening and pretreatment of pure water in preceding stages and the outflow turbidity can be below 3 degrees. The filter is mainly used for reverse osmosis. electrodialysis, ion exchange as well as softening and demineralization system pretreatment and can also be used as coarse filtration of industry water supplying with undemanding water quality, circulating cooling water, reuse water treatment of wastewater and recycled water, etc.
Activated carbon filter
Activated carbon filter is used for the removal of color, taste, residual chlorine and organics its main mode of action is adsorption. Activated carbon is an artificial sorbent. Activated carbon has developed pore structure and huge specific surface area, so it has a strong adsorption capacity for the dissolved organics in the water, such as benzene and phenolic compounds, and has better removal efficiency for organic pollutants which are hard to be removed by biological and chemical methods, such as chroma, stench, surfactants, synthetic detergents and dyes, etc. Granular activated carbon is able to remove 85% of Ag A , Cr2 + and Cr04 A 2 in the water Through the activated carbon filter bed, the suspended solid in the water is less than 0.1 mg/L, COD removal rate is generally 40% to 50% and free chlorine is less than 0.1mg/I. It can be used as pretreatment of ion exchange, electrodialysis and reverse osmosis in pure water technology so as to remove organics, colloids and residual chlorine; it can be also used as an advanced treatment mean after the secondary treatment to ensure the quality of reusewater.
Walnut shell filter is use walnut shell as filter media, specially treated walnut shell, due to the large surface area, strong adsorption capacity, and thus a high removal rate. Stirring walnut shell in motion friction between hydrophilic and lipophilic nature, in the backwash thus the ability desorption, regeneration ability, good chemical stability, long-term stability is conducive to the performance of the filter. Deep bed filtration equipment, can greatly increase the interception capacity. Patented technology attempts to prevent the type maze instead of the ordinary with water control screen to avoid clogging of the filter during operation with Operation time increase or changes in water quality occurs. With strong adsorption, interception capacity; double-effect anti-oil, oil, suspended solids removal; easy regeneration, backwash dosing; can be connected in series or parallel.
Walnut shell filter Scope: (oily wastewater treatment)
1. onshore and offshore oil, petrochemical, metallurgy oily wastewater treatment
2. ports, docks, oil depots and oil sewage treatment
Ship, and other oily wastewater treatment
Walnut shell filter field of application
1. Apply to iron and steel, metallurgical industry, coal industry wastewater and other oily waste water circulation system re-use of treated filter processing;
2. Applicable to the large amount of water, oil field injection water fine filtration, offshore oil platforms produced water recycling and thermal recovery of heavy oil boiler water treatment
3. Circulating cooling water for power plants, refineries and petrochemical plants filter processing and deep processing.
Walnut shell filter works
The filter is separated by filtration principle to the successful development of separation equipment, oil filter - special walnut shell filter media, walnut shell large specific surface area, strong adsorption, the characteristics of the large amount of sewage interception, removal of oil and suspended solids. The device has both automatic and manual control mode. Filter, the water flow from top to bottom, the water distributor, the filter layer, catchment, the filtering is done. Stirrer flip filter backwash water bottom-up, the filter thoroughly clean renewable.
