PES Chemical Material Tubular Membrane / an External MBRr Module for Wastewater Treatment

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.

SUN^® Tubular Membranes / 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 be
separated through the external tubular UF membranes, so as to get high quality ultrafiltration water, and the
concentrated water will return to the biochemical tank. The designed flux is up to 70~120LMH, and the filtration
accuracy can reach 0.03um. The 8mm diameter channel can effectively retain the sludge without causing membrane
fouling. The maximum sludge concentration can up to 40mg/l.



The combination of the tubular UF membrane system with RO or NF can make the landfill leachate effluent 
meet China government level 1 & level 2 discharge standards.
