Technological turn-key projects

Thanks to our own production of tanks, which are further used as parts of technological wholes, we can offer complex solutions (projections including proposals of technical solutions, manufacture, assembly and possible reconstruction or maintenance) for water treatment plants (WTP), biogas stations (BGS) and stores of fertilizers (SLMF). Wastewater treatment plants are widely used in the industry and municipalities.
