POREFLON® Membrane Separation Wastewater Treatment System Do you face one or more of these difficulties? There is not enough space to additional install an wastewater treatmentsystem. You want to use the membrane but are concerned about it. Fouling of membrane It is difficult to maintain the membrane in good condition Breakage of membranes The POREFLON® Membrane Separation Efiluent Treatment System Innovates Effluent Treatment Technology. Achieves Unprecedented Performance and Durability! Using its original processing technology, Sumitomo Electric has developed a highly durable and chemical-resistant separation membrane. Through stable effluent treatment performance, high quality and reliability, excellent durability, and high-quality customer service, Sumitomo Electric is ready to propose wastewater treatment systems that will fully meet various customer needs. onal process and membrane bior Conventional process (conventional activated sludge process) Membrane bioreactor (MBR) Membrane bioreactor (MBR) An wastewater treatment system that combines biological treatment by activated sludge and physical treatment by membrane separation. Raw water is not directly filtered. Organic substances in the raw water are degraded by microorganisms, and the activated sludge used for the treatment is separated by a membrane
Use of a PTFE (polytetrafluoroethylene) membrane with excellent durability and chemical resistance Use of a POREFLON® hollow fiber membrane module
Operates stably over a long period
● The hollow fiber membrane is tough and seldom ruptures. ● The high porosity of the membrane ensures stable operation of the system. ● The membrane can be cleaned with highly-concentrated alkali or acid, ensuring speedy restoration of system operation after membrane cleaning.

Comments of customers
"Membranes made by Sumitomo Electric are very tough and do not tear." Compared with the activated sludge treatment system we used previously, the new membrane
separation wastewater treatment system ensures more stable treatment of water quality. Therefore the new system is easier to maintain. We were concerned about whether the mem-brane used in the new system would tear or clog up. However, membranes made by Sumi- tomo Electric are very tough and do not tear. The membranes rarely become clogged. When one of the membranes became clogged, we were able to clear the clogging by thoroughly cleaning the membrane with a chemical  The membranes are certainly interesting, and we can use them with peace of mind. (Director of a food manufacturing company) "Our membrane separation Wastewater treatment system has been stably operating since we installed it three years ago. We were able to reduce water and sewage expenses by reusing the effluent from the treatment system. For three years since we installed the treat- ment system, it has been stably operating without any trouble, such as tearing or clog ging of the membrane. We are satisfied with using membranes made by Sumitomo Electric (Plant manager of a food-processing company) "Because the membranes are very easy to clean, we don't need to adjust the plant operation." We added a POREFLON membrane unit to a membrane wastewater treatment system new membrane easier to maintain than conventional membranes. With conventional membranes, we had to suspend the operation of our plant every year in order to replace a part of the mem- brane unit with a new one or to remove the sludge from the membrane by cleaning. In contrast, the POREFLON membrane is very easy to clean and eliminates the need to adjust the plant operation. Thus, this mem
brane contributes to the reduction of total plant operation costs. (Engineering department manager of
a beverage manufacturing company)
Conventional process ●Cannot respond to increase in the amount of effluent in association with production expansion. ●There is not enough space to additionally install an wastewater treatment system. The POREFLON® membrane separation Wastewater treatment system Is more compact than the conventional process due to its capability of using activated sludge of higher concentration. Does not require sedimentation since activated sludge is removed by the membrane.
ation and maintenance labor saving
Conventional process
●Controlling the sedimentation tank is labor intensive. ●Requires expertise and experience, so the wastewater treatment system is difficult to control. The POREFLON® membrane separation Wastewater treatment system Eliminates the use of the sedimentation tank, thereby freeing the user from its cumbersome control.
water quality enhancement
Conventional process ●Cannot fully conform to the applicable effluent standard. ●Treated effluent is unsuitable for reuse. The POREFLON® membrane separation Wastewater treatment system Removes solids, bacteria, and other foreign substances to a high degree, thereby enabling the use of treated water as reclaimed water and service water. Examples of actual water quality improvement ● Raw water: ● Raw water: ● Raw water:
