membranesWastewater treatment landfill leachateLeachate from
landfills and incinerators arises mainly because rainwater
penetrates the stored waste, but also from leakage of the garbage.
The polluted leachate is collected by the garbage dump and
undergoes special wastewater treatment.The wastewater from
landfills is characterized by a high variety of
waste.Tubular membranes are particularly suited to liquid with high
viscosity or suspended solids, because their wide flow paths make
them highly resistant to clogging. Tubular membranes system is an
external and separated filtration system. For high solid content
and viscosity liquid, we use adjustable cross-flow velocity to make
the membrane run under optimal conditions and extend membrane
service life. At the same time, it has more convenient cleaning,
maintenance, and operation under closed pipeline.SUN® Tubular
membranes use a cross-flow filtration technology. The cross-flow
filtration can reduce cleaning times and downtime, so as to
maintain a high flow rate. Some membranes are available for back
washing, if necessary, you can also use permeate or chemical
cleaner for back washing, effectively extend the membranes working
life.Decoding of SUN® Tubular Membranes Model What Membrane

/ an external MBR for Landfill Leachate The external tubular
membrane system is a kind of process mainly for high concentration
wastewater treatment,especially for landfill leachate. It is
composed of biochemical process and external tubular UF membrane
system.Pollutants such as organic matter will be removed through
biochemical process and the sludge and water will beseparated
through the external tubular UF membranes, so as to get high
quality ultrafiltration water, and theconcentrated water will
return to the biochemical tank. The designed flux is up to
70~120LMH, and the filtrationaccuracy can reach 0.03um. The 8mm
diameter channel can effectively retain the sludge without causing
membranefouling. The maximum sludge concentration can up to
40mg/l.RisingSun Tubular UF membranes, 30nm, PVDF for landfill
