VACUDEST the effective wastewater evaporator

Wastewater evaporator systems have been established on the market as the most economical method for the processing of a big variety of different industrial wastewaters. It is a viable alternative to the disposal of wastewater with specialized waste management companies or other processing methods. Using our innovative state of the art VACUDEST wastewater evaporator you can separate clean water from your industrial wastewater. Thus you reduce the volume of your wastewater and respectively your waste management cost up to 99 percent. The treated water can be recycled to the manufacturing process creating a zero liquid discharge production.

Nowadays, in almost every industrial sector environmentally dangerous wastewater is produced, which is not allowed to be disposed of into the public sewer system:

• Spent cooling lubricant emulsion
• Release emulsion from die-casting
• Rinsing water from parts cleaning
• Rinsing water from painting pre-treatment
• Rinsing water from plating
• Rinsing water from vibratory grinding
• Rinsing water from salt-bath hardening
• Rinsing water from stainless steelpickling
• Penetrant rinsing water
• Rinsing water from container cleaning
• Landfill leachate

Wastewater evaporator with energy recycling provides for cost efficiency

Energy is an expensive production resource. To save energy we've relied since 1986 on the energy efficient process of direct vapor recompression. The industrial wastewater is evaporated under a slight vacuum. This reduces the boiling temperature of the water. The emerging steam is compressed to ambient, normal pressure and heated up by means of a vapor compressor. The energy of the hot steam is recycled to evaporate the wastewater. Due to the energy recycling in the waste water evaporator no additional evaporation energy is required. The electrical motor of the vapor compressor is the sole energy consumer in the wastewater evaporator system. Thus the VACUDEST wastewater evaporator has an energy efficiency of 95 percent.

Bodycote relies on zero liquid discharge production

During improvement of microstructures of materials such as metals and alloys industrial wastewater is generated. Standard process for the treatment of such wastewater is neutralization and ion-exchange. The treated water is then disposed of into the public sewer system. Due to economic and ecological reasons Bodycote decided to replace this conventional treatment by a modern vacuum distillation system, achieving a zero liquid discharge heat treatment process.

Bodycote is the worldwide leading provider of processing services for the improvement of properties of metals and alloys. Besides thermal processing Bodycote offers services for metal joining, surface technology and hot isotactic pressing.

Hailo Germany: Cut operation cost - Improve process security

Operators in the metal processing industry know the topic process waste water treatment very well: During plating and surface technology processes waste water is occurring which is an annoying evil. Treatment or destruction with waste management companies? The question is answered more and more often with treatment, due to cost savings. But which is the most efficient technology? Which technology offers the lowest operation cost and a good quality of the treated water allowing recycling an a zero liquid discharge production? The case of metal goods producer Hailo, Haiger in Germany, shows: Low operation cost combined with high reliability and process security is possible, when using modern vacuum distillation technology.
