Delanmeier tubular ultrafiltration membrane treatment of textile printing and dyeing wastewater, supporting the sustainable development of the industry

The commonly used methods for treating electroplating wastewater in China include chemical, biological, physicochemical, and electrochemical methods. The physicochemical method is the use of ion exchange, membrane separation, or adsorbents to remove impurities from electroplating wastewater. It is widely used in industry and is usually used in conjunction with other methods. Among them, membrane separation method can recover heavy metals and water resources from electroplating wastewater, reduce its pollution to the environment, achieve clean production of electroplating, and generate good economic benefits.

The treatment process of tubular ultrafiltration membrane technology has no phase change and no adverse effects on material composition. It remains at room temperature throughout the separation, purification, and concentration processes, making it particularly suitable for the treatment of thermosensitive substances. It solves the problem of high-temperature damage to bioactive substances and effectively preserves the bioactive substances and nutrients in the raw material system. No heating required, low energy consumption, no need to add chemicals, and will not pollute the environment.
