How Does Water Treatment Work in Mining Netsol Water
网页Positively charged metal ions react with negatively charged hydroxide ions when the pH of the water is raised. This produces a metal particle that is dense and insoluble, making it easier to work with. pH adjusters, when used correctly, can help to reduce the acidity of your mining wastewater and return it to a more balanced pH level.
