Water circulation, whether it's new or old, requires system cleaning and pre-filming before dosing. The pretreatment of circulating water systems for chemical treatment includes cleaning work and pre-film work. For new systems, small air separation units and piping can sometimes have debris, debris and dust left in the system during installation, and sometimes cooling equipment can be heavily rusted and oiled. If these debris and oil are not cleaned, they will affect the next step of the pre-film treatment. The small air separation unit cooling equipment that has been put into operation also often has scale, slime and metal corrosion products, which can seriously affect the life of the equipment and heat transfer efficiency. Therefore, for new systems, cleaning can improve the pre-film effect and reduce corrosion and scaling. For the old system has been put into operation, cleaning work can improve the heat transfer efficiency, improve the process operating conditions, to ensure a long production cycle, reduce energy consumption and extend the service life of small air separation unit. Therefore, cleaning is an essential part of circulating water system start-up.
