Electroplating factory dedicated filter
Electroplating is a fundamental process machinery manufacturing industry, is today one of the world's three major polluting industries.
The main source of electroplating and metal processing industry wastewater zinc plating or pickling liquid towing. Contaminants through metal rinsing process has shifted to the rinse water. Pickling process involves metal (zinc or copper) was first immersed in a strong acid to remove the surface of the oxide, followed by immersion brightener containing chromic carried strong credit process. The wastewater contains large amounts of hydrochloric acid and zinc, copper and other heavy metal ions and organic brighteners, high toxicity, and some also contain carcinogenic, abnormal, mutagenic toxic substances, great harm to humans. Therefore, the electroplating wastewater recycling process must be carefully, so that eliminate or reduce pollution of the environment.
Filter plating on the following main use:
1; loop filter; plating solution may be dirt; there will be hanging on falling glitches; another may produce anode anode mud; these impurities are likely to be formed blown blemishes on plated parts; therefore; in electroplating production; installation of filter circulation filter bath; may produce less of these defective; generally require filtration 4 to 6 times per hour;
2; when large bath treatment filter; bath using a certain amount of time or some other bath defect; necessary to the plating bath additives and other impurities removed; a processing step is to add hydrogen peroxide (or potassium permanganate) - heating - plus activated carbon adsorption - filtration, then filter machine is mainly activated carbon to filter out solid impurities and other effects;
3, you can also filter when acid water pump
