Walnut Shell Filter with Oily Wastewater Treatment

Model NO.: YLD Usage: Water Treatment Style: Vertical Certification: CE Input Power: 2~20kw Working Temperature: 5-40centigrade Cylinder Material: 304, 316L and Q235 Specification: CE, SGS HS Code: 8421219990 Type: Walnut Shell Motive Force: Pressure Performance: Efficient Filtration Material for Face Piping: Stainless Steel or PVC Power Supply: AC380V, 35A, 50Hz Working Filtration Rate: 5-12m/H and Maxumum 15m/H Trademark: YLD Origin: Jiangyin, Jiangsu 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.
