METHOD OF ADDING ACTIVE CARBON IN WATER PURIFICATION AND METHOD OF WATER PURIFICATION

摘要

In the feeding of raw water for filtration (c) from raw water tank (11) storing raw water (water to be treated) (a) to a membrane module by means of raw water pump (P1), active carbon raw material delivered from active carbon tank (21) together with mixing water (d) is pulverized by wet pulverizer (22) into a water suspension containing active carbon fine particles of 0.1 to 10 mum average particle size, incorporated in the raw water tank (11) and mixed together so as to obtain raw water for filtration (water mixed with active carbon to be filtered) (c). This raw water for filtration (water mixed with active carbon to be filtered) (c) is filtered through a post-process membrane module, thereby obtaining purified water (b).
