AGENTS FOR PURIFYING WASTE WATER AND MUDDY WATER

摘要

It is intended to provide agents for purifying waste water and muddy water whereby suspended matters, heavy metals and so on can be sufficiently separated via aggregation (precipitation) regardless of the pH value even in waste water or muddy water containing these suspended matters at a relatively high concentration so as to give the supernatant water which can be released without adjusting pH and the aggregated precipitate which has a low moisture content and is hardly soluble in water and from which little aggregated heavy metals are eluted again. The above purifying agents for waste water and muddy water contain an organic acid, a crystalline aluminosilicate, an aluminum salt, a magnesium salt, a calcium salt and a sodium salt.
