JPH09194313A - Microorganism elimination agent dissolving in water system - Google Patents

Abstract

PROBLEM TO BE SOLVED: To produce an agent for eliminating microorganisms in water stream, slowly dissolving in water stream to exhibit the microorganism eliminating effect and effective as a perfect slime-removing agent by using a specific metallic compound in combination with water-absorbing inorganic powder and compression molding the mixture. SOLUTION: The objective agent is produced by compression molding a composition composed mainly of a mixture of 5-35wt.% of a silver, copper, zinc or boron compound and >=60wt.% of inorganic powder absorbing >=30wt.% of water based on its own weight. The metallic compound is preferably a water-soluble salt of copper or zinc and the inorganic powder is zeolite, aluminum oxide, etc. The microorganism eliminating agent may be produced by compression molding a mixture of the metallic compound and the inorganic powder or by adsorbing an aqueous solution of a water-soluble salt of the metallic compound to the inorganic powder within the adsorption limit and compression molding the adsorbed powder. In the latter case, especially excellent dissolution rate with water stream and persistency of the elimination effect can be attained by using an aqueous solution of zinc sulfate as the metallic component and porous aluminum oxide as the inorganic powder.
