N compounds speciation removal in biogas wastewater

Location: ITALY

PRODUCED WASTEWATER: 20 cubic meter/hour

Typical problems in wastewater: Nitrites, Nitrates, Ammonia removal

 

TREATMENT PRINCIPLES AND AIMS

To approach a complex wastewater treatment plant, the customer asked us to evaluate the ELECTROCOAGULATION SYSTEM for the removal of NITROGEN COMPOUNDS and to be able to drain the treated water into the sewer system.

Another option required was the ZERO LIQUID DISCHARGE and therefore the possibility of water recycling with the least amount of consumption possible.

This option is possible using an ELECTROCOAGULATION PLANT since no chemicals are used and therefore the physical and chemical characteristics of the water to be treated have little variation compared to the treated water.

 

The obtained results and working conditions are below
