18 제지산업에서물의순환 Today s demands on an efficient and economical treatment of production effluent, greatly exceed mere effluent clarification. Conserving water and recirculating clarified water back into the operation have the highest priority. With our unique combination of anaerobic high-performance clarification and the LIME TRAP we provide water treatment of the highest technical level, at the same time offer low operational costs and a small space requirement. In addition, the largest possible amount of water can be recirculated into the production without compromising on quality. How it works

19 1. PRE-ACIDIFICATION Balance amount and load and serves as the primary process stage for successive anaerobic decomposition 2. RECIRCULATION TANK For the intensive mixing of untreated water with the water loop recirculation stream. By means of the external recirculation, chemicals for neutralizing are saved and a constant hydraulic ratio is achieved, regardless of the accumulated water amount. 4. LIME TRAP TM The targeted elimination of calcium in minimal concentration enables not only a problem-free operation of succeeding on-site equipment, but most importantly closes the water loop circuit. 5. GAS TREATMENT A safe and reliable use of valuable biogas is a very significant part of the anaerobic effluent treatment. Gas tank, gas flame and most commonly desulphurization equipment are in most cases a part of the first stage. 3. REACTOR R2S Two stage high-performance reactor for an economical clarification of industrial effluent. The feed-in and outlet system as well as the gas separator are optimized with regard to possible calcium deposits. Thus, the extraction of calcium containing sludge and sediments is possible without interrupting the operation
