Auckland Zoo Project
Requirement:
Wastewater from Auckland Zoo required treatment to remove e-coli and faecal coliforms to ensure safe compliant discharge back into the adjoining stream. An Envirolyte el-6000 Anolyte generator was installed to disinfect the wastewater prior to discharge.
The daily volume of water to treat is ~ 1,800 cubic metres. Concentration of Anolyte dosed is 0.27 % in Winter and 0.34 % in Summer producing a residual free available chlorine (FAC) level of around 1 ppm.
Outcome:
As shown in the test results table below the project has successfully treated the discharge contaminants to a safe level.
The Hippo pool water visibility is improved, staying cleaner for longer between flushing - a much healthier environment for "Snorkel" the Hippo to wallow in!
Location - Lower Hippo Enclosure
