From tanks to wastewater treatment plants

Enamel, epoxy- coated and stainless steel tanks

Large volume storage tanks, widely used in the agriculture, the water management and the industry areas.

We produce the tanks from three materials - enamel, stainless steel and epoxy coated. The material utilization is similar for all the tanks.

Enamel tanks

Above ground bolted tanks assembled from steel plates with the enamel coating

Stainless steel tanks

The above ground bolted tanks are assembled from the stainless steel sheets with a possibility of choosing from two types of SS (AISI 304, AISI 316) More

Epoxy-coated steel tanks

Epoxy coated steel tanks are made from steel sheets with a special plastic powder coating

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.

Wastewater treatment plants

Waste treatment plants (WTP) for municipal and industrial purposes comply with the strict ecological criteria

Biogas plants

Agricultural and industrial biogas plants (BGP) for the biological waste processing

Liquid fertilizers warehouse

Large-scale magazines for the storage of liquid fertilizers enable continuous dispensing of fertilizers with an option of adding micronutrients
