Client:
WWTP not operated for 5+ years
Industry:
Wastewater
Location:
Victoria, Australia
Key Issues:
Project Summary:
WWTP was not operated for 5+ years
6ML & 8ML capacity ponds
No mechanical intervention used (aerators etc.)
Challenge:
Results:
After 10 weeks biological activity returned to ponds
Water Fleas (Daphnia Pulex) repopulated throughout ponds
Daphnia Pulex are a key indicator of pond health
These bugs appear when water conditions improve and they feed on TSS and sludge
They die off when water conditions are not good - particularly if nitrite and ammonia levels are high.
In simple terms, their ponds became healthier and sludge
consumption by Daphnia Pulex increased
