Celdar® Technology
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.
