Low Effluent Mills

摘要

1. Many Mills on path towards "Closed-Cycle"to reduce effluent flow 1.1 Tempered with need to maintain production, pulp quality 2. Water Reduction in Bleaching to Enable Closed-Cycle 2.1 Alkaline filtrate recycle 2.2 Acid effluent treatment and recycle 2.3 Super Stripping and reuse of Evaporator Condensates in Bleaching 3. LP Samoa, Blue Ridge Paper, Korsnaes, Soedra Moerrums, AssiDomaen Frovi, MoDo Husum, and Metsa-Rauma are leading mills. 4. Both ECF and TCF Paths are Being Developed Eco-cyclic or Minimum Impact Mills offer further refinement over zero-discharge closed-cycle concepts.
