※ Solution management
(1) Check the initial acidity of the solution.
(2) When the time of etching becomes longer, check the acidity and add adequate amount of original solution.
(3) When the solution is used for a long term, change the solution to a new one.
※ Wastewater treatment
(1) Set the pH to 7.5~8.0 with NaOH.
(2) Settle the solution by adding inorganic coagulants.
(3) Filter and discharge.
