Filter for electroplating plants

Effective wastewater treatment with modern filter technology from GEFA Processtechnik

Find out how electroplating companies can improve their wastewater levels to the required standards with the help of advanced filter technology. Choosing the right water treatment system is crucial for recovering process water, and GEFA Processtechnik's automatic self-cleaning system offers an ecologically and economically favorable solution.

Challenge in the electroplating industry

During hot-dip galvanizing and other processes, steel coils are treated, resulting in waste water containing chromium, nickel, copper, lead and other residues. Conventional cleaning methods often reach their limits here:

Bag filters do not achieve the desired discharge values, especially with high dirt loads.
In high-pressure applications, more fresh water than necessary is used, which leads to increased waste water.
Losses from carryover and evaporation must be compensated for with additional demineralized water.

The solution: an innovative filter concept

Our new filter concept comprises several components that work together to effectively and efficiently remove contaminants:

An oil separator separates leaking oil from the wastewater.
A special plate separator reduces the oil load in the water.
An automatically self-cleaning Filtomat serves as a pre-filter for the deep-bed filter.
An activated carbon filter reduces the oil concentration in the water.
An MT-IBA microfiber filter removes colloids from the water.
