Method and apparatus for clarifying industrial water |
| abstract |
Provided are a method and an apparatus for clarifying industrial water that enable industrial water to be clarified to a high degree with a small amount of coagulant instead of an inorganic coagulant, such as PAC, aluminum sulfate, or ferric chloride, which need to be used in a large amount for clarifying industrial water and are capable of producing treated water having qualities particularly suitable for an RO membrane treatment. The method for clarifying industrial water includes adding a melamine-formaldehyde resin acid colloidal solution to industrial water in order to coagulate the industrial water and subsequently filtering the coagulated water. The coagulated water may be directly filtered with a pressure or gravity filtration device, or with a microfiltration or ultrafiltration membrane module, without being subjected to solid-liquid separation using a sedimentation or floatation separation device prior to the filtration treatment. |
