"Zhongkehai" in aquaculture rapid sand filter cylinder, can  efficiently remove of various types of plankton, algae in water, inorganic, organic debris or fiber pulp, heavy metal ions, partially soluble substances, protein, softening water quality, improving the clarity.It covered an area of less, small head loss, a valve control, easy installation.The capability to filtering is strong and flexible.

the product feature

 ZKH - SL1200A technical parameters:

Nominal flow: 50 tons/hour

Filter area: 1.20 m 2 (1200 mm)

In and out of the water size: 63 mm

Unique patent recoil technology, be able to complete the recoil process thoroughly, and completely put an end to harden sand layer. Recoil water saving, prolong maintenance cycle. After the traditional sand filter equipment is used for a period of time (usually only 1 to 2 months) . the recoil frequency more and more high, even will recoil  once every 5 hours .At the same time filtering effect decreased .In the process of, a lot of manpower material resources are consumed .Sand serious corruption, black, and with the stench! Cause secondary pollution to the aquaculture water. This is the harden sand layer. According to the above situation, combining with the industry forefront of foreign advanced technology, the company developed the aquaculture rapid sand filter cylinder, solved this difficult problem thoroughly,  and improved the efficiency of recoil .Recoil water decrease greatly, and don't have to change regularly sand that can  experience the efficient filter of "new sand filter equipment" permanently!
