The treatment of landfill leachate by DTRO membrane has the advantages of simple pretreatment, low water quality requirements, high recovery rate and desalination rate.
DTRO membrane has the advantages of high working pressure, strong blowdown capacity, wide fluid channel, high maintenance and cleaning tolerance, simple and convenient maintenance and replacement.
DTRO membrane has the advantages of low operating cost, small floor space and wide application range.
DTRO membrane is especially suitable for landfill leachate, petrochemical industry, seawater desalination, acid-base recovery, emergency mobile water purification and so on. But the initial investment cost is high.
Although the coil reverse osmosis membrane is simple in pretreatment, low in operating pressure and relatively low in initial investment cost, it has high inlet water quality requirements, low recovery rate, low desalination rate, weak sewage discharge, narrow fluid channel and low maintenance and cleaning tolerance. It needs to replace the whole membrane column for maintenance, high in operating cost and large in occupied area, and is more suitable for standard media, standard membrane columns and large factories.
