Product Details

Many metal and plastic parts that we encounter every day are painted. By painting, these parts are sealed and protected against external influences such as rust, weather or sunlight. Usually, there is always a pre-treatment which consists of  numerous pre-treatment processes due to the different parts to be painted., The parts must always be thoroughly cleaned to ensure that the painting has got a long shelf life and fulfils its purpose

Rinsing water treatment is becoming more and more important in paint pre-treatment and it has become an indispensable, quality-critical production process in the recent years. For this reason, more and more companies are using vacuum distillation plants for the recycling of rinsing water.

Vacuum distillation is the state of the art technology for the circulation of rinsing water

No matter whether iron phosphating, degreasing or nanoceramics – today vacuum distillation plants are the state of the art technology for the treatment and recycling of rinsing water from paint pre-treatment. Depending on the processed material and the desired corrosion protection of the intended workpieces to be painted, a special pre-treatment process might be recommended. Once the process stages, chemistry and water quality requirements have been determined, a suitable treatment system can be planned. Not only the size and type of evaporator are selected, but also the necessary components such as containers, neutralisation equipment, ion exchangers and reverse osmosis systems.

The goal of a process water technology is always a reliable and automatically working system: The paint pretreatment must not fail due to bad or fluctuating water qualities in the circulation system.

The concept developed by H2O GmbH based on the latest technology provides a very simple, flexible and modular system which is suitable for a wide range of possible coating processes. 

Possible types of wastewater:

• Degreasing water (alkaline, neutral or acidic)
• Rinsing water from iron phosphating
• Rinsing water from zinc phosphating
• Rinsing water from the pickling plant
• Rinsing water from the chromium-free conversion
• Rinsing water from nanoceramics (zirconium-containing chemistry)
• Liquids containing blasting agents
• Wetting agents and corrosion inhibitors
