Risingsun Tubular UF Membranes, 30nm, PVDF membrane for waste water treatment, Cross Replacement Pentair X-FLOW Compact 27/ UF membranes
Wastewater treatment landfill leachate
Leachate 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.

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.
RisingSun Tubular UF membranes, 30nm, PVDF for landfill leachate, cross replacement Berghof membranes.
Use of RisingSun Membranes tubular UF filtration ensures complete solids retention, efficient system operation and process stability at all times.
External crossflow filtration technology is a good choice for :
Superior Effluent Quality
Increased Treatment Capacity
Smaller Footprint
Low Sludge Production
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.

Cross Replacement: Berghof membranes/ Pentair Membranes
Membrane Storage:
New membrane modules can be stored as supplied.
Membrane modules should be stored in a dry, normally ventilated place, away from sources of heat, ignition and direct sunlight.
Store between 0 and 40 °C. The membrane modules should not be subjected to any freezing temperatures.
After use, UF membranes need to be stored wet at all times.
To avoid biological growth during shutdowns or storage, wet membranes should be treated with a compatible biocide.
The membrane is compatible with many common disinfecting agents or biocidal preservatives. For short-term shutdowns, a daily flush with permeate quality water containing up to 2.0 ppm free available chlorine for 30 to 60 minutes may be adequate for bacteria control.
In case of long-term storage, membranes should be cleaned before the disinfection step is carried out.
For disinfection, a 1% sodium metabisulfite solution can be used.
In either situation, modules should be stored hydraulically filled.
