Using the Advanced Oxidation Processes (AOPs) likely ozone / UV / H2O2 / composite metal catalyst to decades dissolved organic pollutants in wastewater. In AOPs technology, ozone is added to the contaminated water and is activated by the catalyst or UV or H2O2 to form secondary oxidizing species likely hydroxyl radicals.

Precious metal recycling equipment

If the process wastewater contains valuable metals, such as gold, palladium, copper, nickel, etc., the system design will design electrolysis or resin adsorption methods based on water quality concentration and characteristics to recover valuable metals in water. The principle of electrolysis is that waste water passes through an electrolyzer to reduce and recover positively charged metal ions at the cathode; the principle of adsorption is to use a chelating resin to remove specific metal ions in water, then regenerate after saturation, and recover highly concentrated valuable metal ions in the regeneration liquid.
