In the assumptions of our projects, the fundamental principle is closing circulations or reducing the amount of sewage in water treatment and purification processes. Such an idea is now in line with the water management policy. Many countries have introduced restrictions on water use, which today affects mainly the industry, but increasingly affects the civilian population. There are many ways to motivate water saving and we act in accordance with these principles. All our purification, purification and treatment systems are in the form of mobile containers, which saves time in a bureaucratic sense (permission).
