Multi-functional Filter

It is a new pattern and high efficient sewage treament system,it is used for treating produced water in oifield high precisely.afer filltration the water can be used for injection from earth or ocean oifiel or drain.the feature are small in size.large capacity of treatment,high filtration precision,extract oil and sewage when operation,good to requirement or injection or drainage water.The design and manufacture of the multi-functional filter carry out the standard of SY/T 0532 <Oilfield >

Features

It adopts the walunts in shell,which has strong absorb ability and is filtered after special treatment ,as filter medium.Filter material can be rewash and refresh.The ability of resistance to pressure(2.34mPa) is strong.The chemical proprety is steady(not easy to dissolve in the acid-base solution).Hardness is high.Abrasion resistance is good .Usage life is long(add 10% filter material every year).Absorptive power is strong(absorption is 27-50%).Hydrophilic nature is good.Oil immersion is good.Specific weight(1.226g/cm3) of filter material is little larger than that of water and it is easy to rewash and refresh.The most importent feature is that rewash is used the water before or after filtering & kneading and swirl refreshing outside tank by filter material recycle pump without gas and chemical medicament.The cost is low and the service life is long.It can adopt single-stage parallel connection or two-stage in series according to water quality.
