Method for producing alginate flocculant aid (coagulant) for treatment of raw water

摘要

The present invention relates to a polymer coagulant which is a main constituent of a cell membrane of brown algae (brown algae, seaweed, kelp, kim, etc.), chemically a carbohydrate but unlike starch fibrils, alginate, which is a chelate polymer having a carboxyl group, (Turbidity) and heavy metals present in the raw water and tap water at the same time.
