Filter press used in electroplating wastewater
Electroplating is the process of plating various metals on metals or other materials using chemical and electrochemical methods. Electroplating technology is widely used in machinery manufacturing, light industry, electronics and other industries. The water quality and quantity of electroplating wastewater are related to factors such as the process conditions, production load, operation management and water use of electroplating production. The water quality of electroplating wastewater is complex and its composition is difficult to control. It contains heavy metal ions and cyanide such as chromium, cadmium, nickel, copper, zinc, gold, silver, etc. Heavy metals are a category of wastewater with great potential hazards in the electroplating industry. Some of them are highly toxic substances that are carcinogenic, teratogenic, and mutagenic. These substances seriously endanger the environment and human health.
As a mature dehydration equipment, filter press is widely used in the field of environmental protection and has become an important equipment for sewage sludge treatment. Mechanical dehydration of sludge mainly removes the capillary water between sludge particles. The moisture content of sludge after ordinary mechanical dehydration is usually 65%-80%, in the form of mud cake.
