Problems solved by technology

[0008] However, water treatment compositions for preventing corrosion and scaling are less effective in preventing microbial growth, and water treatment compositions for preventing microbial growth are less effective in preventing corrosion and scaling
Therefore, the use of conventional water treatment compositions is limited, and users must inject suitable water treatment compositions according to water quality conditions
The reason for separately developing corrosion inhibitors, scale inhibitors, and microbial inhibitors is because if all of them are mixed to form a composition, the stability of the product is deteriorated and precipitates are formed due to lack of compatibility between the components
In addition, the possible effects of each component cannot be fully utilized

Abstract

In order to provide a water-treating compositon which has a superior stability during storage or the use and simultaneously prevents the corrosion, the scale formation and the growth of microorganism in a colling water, the present invention provides a multifunctional water-treating composition comprising at least one component selected from a group consisting of a mixture including azole compound and carboxylate, orthophosphate salt and zinc salt; a microorganism growth inhibitor; a scale formation inhibitor; an organic phosphonate; and nitrate.

Description

technical field [0001] The present invention relates to a multifunctional water treatment composition and a water treatment method using the composition. More particularly, the present invention relates to water treatment compositions which have excellent stability in storage and use while simultaneously inhibiting corrosion, scaling and microbial growth occurring in open circulation cooling water systems. technical background [0002] In the open circulation cooling water system, the cooling tower equipment is used to control the temperature of the cooling water. Because the air always flows into the water temperature control system with cooling tower, then the system is called open circulation cooling water system. In the recirculation of cooling water, various minerals contained in the water are concentrated due to the evaporation of the water. Depending on the wastewater treatment method, there are various phenomena that affect the cooling operation. These phenomena c...
