Reverse Osmosis (RO) systems separate leachate into a high quality permeate while retaining organics (BOD, COD, organically bound nitrogen), ammonia, PFC/PFAs, heavy metals and salts. The WEHRLE DIRECT-RO uses organic spiral wound modules in a feed & bleed configuration at a pressure of 80 bar. These membranes are produced in high volumes worldwide and offer an optimum price/performance ratio and independ-ence in membrane replacement. The membrane modules have been specially developed for use with difficult...
Effluents from waste (leachate) are highly polluted and must be treated efficiently before they can be discharged into a municipal sewage plant or a local watercourse. Conventional treatment technologies do not suffice. Chemical processes are not economic due to the high pH buffer capacity of the leachate. Hardness and chlorides in the leachate are a problem for many plant components. Besides, process knowhow and operating experience are indispensable for an effective elimination of the harmful ammonia nitrogen....
