Title:
PRODUCTION METHOD FOR WATER-PURIFYING AGENT, AND WASTE WATER TREATMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2018/051848
Kind Code:
A1
Abstract:
A production method for a water-purifying agent that comprises a granulated substance that contains a plant powder and a polymer coagulant. The production method is characterized by including a step for mixing and kneading the plant powder and the polymer coagulant such that the hardness of the kneaded mixture obtained by means of the mixing and kneading demonstrates a stress of 3-100 N/mm2 under the following measurement conditions: a stress-controlled rheometer (a viscosity measurement device) is used to measure the stress at a push depth of 5 mm when a probe that has a diameter of 16 mm is pushed into the kneaded mixture at a pushing speed of 30 mm/min.
