Foamproof vacuum distillation plants

Foamproof vacuum distillation plants with forced circulation, vapour compression and fully automated CIP (cleaning in process). The distillation output of this line of products ranges from 30 to 4.000 l/h.

Membrane process equipment

Membrane process equipment is projected and built according to customer specifications and the volume and composition of the water. Optimized solutions are achieved with custom systems or combinations with other processes.

Vacuum distillation systems with natural circulation and vapour condensation.

Vacuum distillation systems with natural circulation and vapour condensation. The distillation output of this line of products ranges from 10 to 120 l/h. These low-investment systems combine high distillation quality with rugged system technology. The integration of the heat exchanger in the evaporator sump means reduced structural dimensions and smaller space requirements in production. Foaming is effectively reduced by means of automatic defoaming agent dosing. All components are arranged under an insulated soundproof hood so as to be easy to service.

WASTEWATER-FREE COOLER CLEANING

Efficient, low-cost treatment of washing water from cooler cleaning with PROWADEST® evaporator technology! Economy and ecology in harmony: This is no contradiction for Behr Industry, part of the Behr Corporate Group. It is a daily challenge. Environmental protection is not only solidly established in the Behr corporate philosophy, it is also firmly anchored in an environmental management system and internationally certified. A good example is the PROWADEST® evaporator system put into operation at the service location Schwäbisch Hall. The used washing water from the cooler cleaning operation is treated and the purified water (distillate) is returned to the production cycle. Behr Industry is part of the Behr Group with an annual turnover of exceeding 3 thousand million EUR and over 16,000 employees. Behr Industry has for decades been Europe’s market leader in the cooling of rail vehicles driven by diesel or electric drives. Cooling systems for large-scale engines, special vehicles, buses, construction machinery and aircraft are also produced. All customer systems are overhauled and repaired at the service location in Schwäbisch Hall: The systems are dismantled and cleaned with the high-pressure cleaning equipment. Specific cleaning of individual components is done in an ultrasonic bath. Then defective coolers, engines, regulators and other parts can be inspected and repaired. Successful testing on the test bench is followed by assembly, painting and application of preservative agents. This complete overhaul service means customers get back cooling aggregates within a very short time that are as good as new and once again meet specifications 100%. The previous method was to treat all washing water from parts and cooler washing in a conventional, physiochemical water treatment plant. The residues from the chamber filter press were disposed of and the treated water was discharged into sewage. In view of highly stringent sewage discharge legislation (heavy metals, COD, etc.) for public sewers and the considerable costs involved, a decision was made to realize a clean, low-cost and resource-friendly solution in cooperation with KMU Umweltschutz GmbH. A decisive factor in our decision was KMU’s capacity as a system supplier to provide all of the process technology, including the necessary laboratory work, construction and runup of the system and a “turnkey” process guarantee – all under a single roof. The core of the treatment system is a PROWADEST® evaporator for low-cost wastewater treatment. The conditions for the new investment – compliance with specified sewage discharge levels and reutilization of the distillate for cooler cleaning – were met in full.
