Our guidebook on the subject of "wastewater-free production".

"An investment in knowledge pays the best interest." - Benjamin Franklin already knew that 200 years ago. That is why we would like to share our expert knowledge with you: Here in our guidebook! On this page you will find informative explanations and interesting facts about wastewater, such as functional descriptions and comparisons of different technologies and processes. Practical and comprehensible. We hope you enjoy browsing and informing yourself!

Vacuum distillation

Water is used in the production of almost any product, whether it is a car or a toothpick. The so-called industrial water generated in production processes is usually contaminated after the production process and polluted with heavy metals, oils or salts. This contaminated water can cause severe environmental damage if it is returned to the public supply without first being purified. It is therefore an efficient long-term strategy to purify the contaminated water directly in the facility where it was produced, since the contamination usually makes up a small fraction of about 2-3% in the wastewater and the purified water can be reused directly in the facility. And this is where vacuum distillation comes into use.

Vacuum distillation pump

Vacuum distillation reliably and gently separates substances with different boiling points. For a vacuum distillation process to run reliably and for the separation process to deliver high-quality results, it is important that the vacuum in the evaporator is meticulously maintained. This places high demands on the vacuum pumps as well as on vacuum control and the choice of the correct, high-quality pump is a very important factor in a vacuum evaporation plant. Depending on the application, different vacuum pumps are used.

Which vacuum pumps are especially suitable for distillation purposes?

Industrial vacuum distillation

Water is used in almost every branch of industry in one way or another and in varying quantities. The types of wastewater generated are as diverse as the industries themselves. While demand for water is steadily increasing, at the same time it is rapidly becoming a scarce and endangered resource.

This is not only a major problem in third world and emerging countries, but it is also already becoming apparent in western European industrialized nations. 

Industrial wastewater treatment process

Industrial wastewater contains a wide variety of contaminants. These can include for example heavy metals from a metal-processing plant, fats and oils from parts cleaning or medicinally relevant substances or ingredients from the pharmaceutical industry - the wastewater is as diverse as the processes themselves. There is a plethora of different industrial wastewater treatment methods on the market - all with their specific strengths and weaknesses. Here is an overview of the most common processes:

Processes accumulating waste water

Industrial waste water is the polluted water generated by industrial processes. Depending on its source, it is contaminated with a wide variety of pollutants and must be treated before being discharged into public supply networks.
