Our work in the wastewater industry

Backwashing

Treated water which was stored in a storage tank is pumped in the reverse direction as that of the water flow direction during filtration process. Backwashing is a form of preventive maintenance so that the filter media can be reused. For a filter to work efficiently during a filter run, regular backwashing is needed.

Municipal wastewater

The liquid contains high concentrations of large solids that can be handled only using pumps with vortex impeller.
The pump provided to the customer can work with sludge with viscosity up to 300CP and solids up to 110 mm.

Wet scrubber

Pumps are used for water circulation in wet scrubbing system of a blast furnace. The pump is able to guarantee, thanks to the use of the channel impellers, high efficiencies even with dirty liquids.

Digester feeding

Pumps are used for liquid feeding inside the digester in a biogas plant. The sillage is water containing wastes coming from the production of food obtained by using soya seeds. The pump is able to guarantee, thanks to the use of the channel impeller, high efficiencies even with dirty liquids.

Wastewater treatment plant

Pumps are used for liquid recirculation inside the digester in a biogas plant. The liquid contains high concentrations of solids that can be handled only using pumps with vortex impeller. The pump provided to the customer can work with viscosity up to 500cP.

Multiple effect evaporator plant

The pump is used to extract concentrated liquid from the concentration tank where involatile elements are separated from a solution, obtaining deionized water and a “concentrate”.

The use of the vacuum evaporation technique allows to reduce not only the energy consumption but also the NPSHa available for the pump. HG pumps, thanks to special design of impeller, are able to work with very low NPSHa values. Pumps are equipped with mechanical seal designed to work in high vacuum condition

Wastewater treatment plant

The pumps circulate the primary sludge in a WWTP.

The liquid contains high concentrations of large solids that can be handled only using pumps with vortex impeller (solids up to 110 mm).

Digester recirculation

Pumps are used for liquid recirculation inside the digester in a biogas plant in a factory that produce wine and highly alcoholic products. The liquid contains 6-8% of fine particles that can be handled using pumps with semi-open impeller.

Forced circulation evaporator

The pump is installed in a forced circulation wastewater evaporator to treat industrial wastewater. Its high efficiency enables treatment of effluents that are otherwise difficult to treat, such as brines, oily water, RO rejects, washing waters, etc. Pump is in duplex SAF 2205. The use of the vacuum evaporation technique allows to reduce not only the energy consumption, but also the NPSHa available for the pump.

Multiple effect evaporator plant

Circulation pumps for high corrosive boiling media containing chlorides up to 50 g/Liter in a three step vacuum evaporation plant for electro plating waste waters. The use of the vacuum evaporation technique allows to reduce not only the energy consumption, but also the NPSHa available for the pump. Pumps are in duplex SAF 2507. RDL pumps, thanks to special design of impeller, is able to work with very low NPSHa values. Pumps are equipped with double mechanical seal designed to work in high vacuum condition
