Industrial Wastewater Solution

Scope of application:

● Various electroplating wastewater treatment, including cyanide containing wastewater, single and mixed heavy metal wastewater containing chromium (Cr), copper (Cu), zinc (Zn), nickel (Ni), cadmium (Cd), etc;

● PCB circuit board wastewater treatment;

● Other wastewater containing heavy metals.

Technical principles:

The equipment takes functional nano Ceramic membrane as the core element, uses the nano pore filtration technology on the surface of Ceramic membrane and the binding force of the nano pore double electric layer in the membrane to intercept heavy metals; Adopting a unique operating mode to slow down membrane blockage. During the treatment process, flocculants such as iron and aluminum series and polymer coagulants such as PAM are not added, resulting in high heavy metal content and easy dehydration of the sludge. It can be directly recycled and utilized as a resource.

Product advantages:

● Without adding flocculants or coagulants, the metal content in sludge is high, which is conducive to resource recovery and utilization;

● Unified treatment of heavy metal mixed wastewater such as copper (Cu), nickel (Ni), chromium (Cr), zinc (Zn), cadmium (Cd);

● The heavy metal content in the effluent meets the standards in Table 3, and the operation is stable and reliable;

● Functional nano Ceramic membrane is adopted, with a service life of more than 20 years; Integrated equipment, fully automatic control, remote monitoring;

● Advanced technology, high efficiency, and small footprint.
