As a side-effect of shock absorber production process certain amount of wastewater is created particularly during cleaning, hard chromium electroplating of piston rods and E-coating processes.
EKOL Ltd. company delivered wastewater treatment station for treatment of all kinds of wastewater from above mentioned surface finishing technologies. The treated wastewater is partly recycled as technological water and partly discharged to municipal sewage of town Gliwice.
