Title: Bivalvia exterminating method for cooling water system
Inventor: KAJIWARA SHOICHIRO
IPC: F28F19/01
Filed: 1993-06-10
Abstract: PURPOSE:To efficiently and certainly prevent a trouble caused by attachment of bivalvia, by a method wherein hydrogen peroxide is dosed into a cooling water system for a specified period of time so that hydrogen peroxide in the cooling water reaches a specified concentration and attached organisms, i.e., young bivalves attaching themselves to pipings, heat exchangers and others, are exterminated. CONSTITUTION:Bivalvia includes blue mussels, green mussels, zebra mussels, etc., for example, which breed and grow in water and attach themselves to walls of piping, heat exchangers, etc., with their byssuses. Objective organisms for extermination are young ones among those bivalves, which have shell lengths smaller than 0.3-5mm. Byssuses of young bivalvia can be broken by dosing hydrogen peroxide into cooling water for 0.5-24 hours, preferably 0.5-12 hours, so that the concentration of hydrogen peroxide in the cooling water reaches 0.5-2%, preferably 0.1-1%. Thereby, consumption of hydrogen peroxide can be reduced because dosage of hydrogen peroxide that does not cause environmental problems is carried out only when attachment of young bivalvia occurs.
