處理工藝
當原液通過分離膜時，水透過分離膜，原液返回到原液槽。再一次通過分離膜，又有新的水透過分離膜，這樣連續循環，直到原液槽的水位低于目標水位，處理結束。一般能夠濃縮到原液的1/10~1/20。
Treatment process
When the original liquid passes through the separating film, the water passes through and the original liquid returns to the tank. Once again there is new water through the separation film , the cycle circulates until the water level of the tank is lower than the target level.
