Product and process water
Process water treatment is required wherever water is available that is not suitable for the planned process. We investigate how raw water can best be brought up to the required process water quality. The customer's environmental conditions are also taken into account, resulting in the most efficient treatment possible.
We have experience in water treatment in the following areas:
​
-
Contaminated site remediation
-
Chemicals, oil, gas
-
Process water treatment for fuel cells
-
Product water
-
Rinsing water

Container system for well water treatment refinery
In 2020, we supplied a container-mounted well water treatment system with a brine bunker for supplying liquid brine to the water softening plant for a refinery in Rhineland-Palatinate.
​
Complete container assembly planned and executed by us:
-
Sand filter
-
Quality-controlled double softening system in serial duplex piping
-
Double pump station
-
Flushing pumps and flushing air blowers for the filters
-
SPS-S7 control system with touch panel visualization and data exchange with control room
Water softening from
contaminated site remediation
Contaminated site remediation has been underway for some time at the factory premises of the largest automotive supplier in Stuttgart. The groundwater level is being lowered within the factory premises. The water produced in this process is softened and then stripped of chlorinated hydrocarbons using a stripper. The exhaust air is treated with activated carbon. The water goes into the receiving water (in this case, this means direct discharge into a river, i.e., not through a sewage treatment plant). The treatment costs are very high.
​​
Task
The existing water softening system was approx. 40 years old and very inefficient. The system needed to be overhauled.
​
Solution
During our inspection of the system, we determined that it was operating very inefficiently. A 50% reduction in operating costs, salt, wastewater, and electrical energy was realistically possible. The existing water softening system was replaced with a new system featuring modified process technology. Capacity 3 x 50 m³/h at up to 50°dH total hardness. The system was equipped with hardness sensors to adapt to fluctuating water hardness.
