Composite solid water treatment products

Abstract

The present invention provides a composite solid water treatment product which can safely make a halogen-based oxidizing agent and an active ingredient reactive with the halogen-based oxidizing agent, and maintain the excellent drug effect brought about by the combined use of these active ingredients , and convenience in handling are also excellent. A composite solid water treatment product for use by dissolving in water to be treated, comprising a solid agent (A) of a halogen-based oxidizing agent containing a halogenated hydantoin-based compound as an active ingredient, and The solid agent (B) of the organic bactericide having reactivity with the halogen-based oxidizing agent is accommodated in the elution container without being in contact with each other.

Description

technical field [0001] The invention relates to a composite solid water treatment product, which is a water treatment product used in various water systems such as industrial water or cooling water, cold and warm water, boiler water, process water, waste water, etc. treatment agent. Background technique [0002] In various water systems such as industrial water or cooling water, cold and warm water, boiler water, process water, waste water, etc., in order to prevent corrosion and scaling of metal components used in these water systems, and to prevent microorganisms such as bacteria or algae in the water system Various water treatment agents such as anti-corrosion agents, anti-scaling agents, bactericides, and algaecides have been used. [0003] In many cases, water treatment agents used for such purposes seek to maintain a high chemical effect over a long period of time. Therefore, a method of continuously injecting a liquid water treatment agent into the water system to b...

AI Technical Summary

Problems solved by technology

[0004] However, in terms of equipment, there are also facilities where it is difficult to inject the water treatment agent with a chemical solution injection pump, etc. In this case, another mechanism for sustaining the effect of the chemical is required

[0005] In addition, even when devices such as chemical liquid injection pumps can be installed, for example, in a small cooling tower, the cost and maintenance burden of the devices are large for installing these devices.
