Project Background: The company's production wastewater contains high levels of organic matter and heavy metal ions. The existing system could not meet discharge standards after treatment, posing a risk of production restrictions.
Core Process: A pretreatment + reverse osmosis deep treatment process is adopted: The front end uses sedimentation and filtration to remove large particulate impurities, reducing the risk of membrane fouling; the back end uses reverse osmosis semi-permeable membrane technology, achieving separation of water molecules and pollutants through pressure difference.
Application Results: The treated wastewater achieves a COD and heavy metal removal rate of over 98%, fully complying with industry emission standards; 70% of the produced water can be reused in production, saving over 8 million yuan in water resource costs annually and avoiding fines and production stoppage losses due to excessive emissions.
