Rinsing is a crucial component of a surface finishing process. Without a rinse between stages, incompatible chemicals may mix, causing contamination and other hazards.<\/p>\n
The main purpose of rinsing between chemical processes is to protect from contamination. For example, alkaline cleaners\u00a0must be thoroughly rinsed before entering acid activation. This will ensure that no solids are formed,<\/p>\n
Rinsing may\u00a0also be used prior to drying as the final step in removing chemical residues prior to drying. Final rinses, typically\u00a0high in temperature aid in drying, eliminate the concentration of residual salts improving corrosion\u00a0protection.<\/p>\n
There\u2019s a balance to rinsing – using enough water without using too much. The impact of rinse water usage includes water costs, waste treatment costs, and process integrity.\u00a0Consider many factors when determining flow rates of rinses to ensure process integrity and minimize the costs associated with rinsing. Keep your operations pristine with these protocols for good rinsing.<\/p>\n
Good Rinsing Protocols<\/strong><\/p>\n Reduce Water Usage<\/strong><\/p>\n Counterflow rinsing is a good way to reduce water usage and improve the integrity of the entire process. However, counterflow rinsing has drawbacks including additional equipment costs, floor space, and process steps.<\/p>\n Rinsing processes can also be improved using dragout rinse tanks. Dragout can reduce rinse water usage by eliminating contaminants being introduced into the rinse.<\/p>\n\n
