Demineralised water - Import export

The TWT combines a number of cleaning methods in a single unit. Through immersion any spray cleaning with alkaline, neutral or slightly acidic aqueous media, it caters for a wide range of parts and meets even the most stringent requirements regarding technical cleanliness. The cleaned parts are dried under vacuum for extra fast processing. All machine components that come into contact with media are made in stainless steel, allowing for the use of fresh and demineralised water.

Complete deionisation with electro deionisation With electro deionisation, permeate of reverse osmosis or other process waters can be completely demineralised. According to the VGB recommendations, a max. conductivity of 0,08 µS/cm is allowed for fully demineralised water.

Complete desalination with ion exchangers With ion exchangers, permeate of reverse osmosis or other process waters can be completely demineralized. According to the VGB recommendations, a max. conductivity of 0,08 µS/cm is allowed for fully demineralised water.

Ultrafiltration of kathodic deposition paint The filtrate of the ultrafiltration is added to the immersion bath by a spray ring, which is installed directly over this bath. So, the recovery of the remaining color is possible and by separation the color particles, painting defects can be avoided. In the last spray zone, organic solvents from the ultrafiltration are washed away be demineralised water. Concentrated with these solvents, the water is leaded into the color bath. The process is a closed loop without any waste waters. The paint bath can be contaminated with pre-tretment chemicals like e.g. phosphates, chlorides, chromates. so, a part of ultrafiltrate has to be leaded out to avoid concentration of the paint bath with these chemicals. If no ultrafiltration is used, big amounts of waste waters will arise, which are difficult to dispose. Our ultrafiltration plants are customized in membrane are, retention rate and membrane type.
