운전원리운전원리

§ 폐수는 (1)을 거쳐 반응기 하부로 유입되고, 혐기성미생물과 강하게 혼합된다.

§ 유입구 부분은 불가피한 스케일이 운전에 방해없이 배출될 수 있도록 특별하게 설계되었다.

§ 2개의 3상 분리 시스템(4, 5)은 폐수와 가스와 혐기성미생물의 효과적인 분리를 고려한 것이다.

§ Biogas, 물 그리고 혐기성미생물은 Riser(8)를 통해 반응조 아래에서 반응조 위의 Degassing tank로 직접 이동한다. 그후 혐기성미생물은 다시 Downer(9)를 통해 반응조 아래도 되돌아 온다.

§ 내부순환 및 외부순환을 추가하여 운전할 수 있다.

§ 처리수를 위한 유출시스템은 퇴적을 피할 수 있는 방법으로 설계되었다.

제지산업에서제지산업에서 물의물의 순환순환

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 recirculatedinto the production without compromising on quality.

How it works

1. PRE-ACIDIFICATIONBalance amount and load and serves as the primary processstage for successive anaerobic decomposition

2. RECIRCULATION TANKFor 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.

3. REACTOR R2STwo 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

4. LIME TRAPTM

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 TREATMENTA 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.
