The reduction in the use of production water began with the selection of places with the highest degree of its use and the potential for savings. The process of washing devices, tanks and systems in a plant producing colour paints was analysed. Measurement of water consumption for washing was initiated at the beginning and then changes were introduced in the process, such as pre-cleaning the elements by taking advantage of compressed air. Employees were subject to training in a standardized method of cleaning industrial systems.
The Company also saw possibility to reduce water consumption in pressure and automatic tank washing. Numerous trials and tests were carried out in this regard, but they did not bring satisfactory results, and therefore these activities were discontinued. Experimentally, „scrapers” were installed to reduce the amount of paint remaining on the walls of the tank after emptying it. Their installation contributed to easier and more economical cleaning of tanks and higher mixing efficiency.
