Efficient wastewater treatment in paint pretreatment
Consistent water quality – for perfect painting results
Whether body parts, housing components, or support profiles—, painted surfaces are standard in almost all industrial products. But before the paint can be applied, thorough paint pretreatment is necessary. This process produces large quantities of rinse and process water that is contaminated with cleaning chemicals, phosphates, metal ions, or degreasing agents.
With MKR's atmospheric evaporators , this water can be treated safely, economically, and in compliance with legal requirements—and, if necessary, in such a way that the treated water can be returned to the process.
Sustainable recycling instead of discharge
MKR offers customized system solutions for the safe treatment of typical wastewater from pretreatment – including:
- pH adjustment • Filtration (bag filters, belt filters)
- Pre-separation of oils, particles, sludge
- Atmospheric evaporator
- Optional discharge monitoring (pH, temperature, volume)
- Reverse osmosis system / ion exchanger for VE recirculation flush
Individually customized – for all pretreatment processes
Whether iron phosphating , zinc phosphating, degreasing , or modern nanoceramic systems : we design the systems precisely according to your requirements—taking into account the chemicals used, the desired recovery rate, and the available space.
