Pukete Digesters
The Pukete Wastewater Treatment Plant included two mesophilic anaerobic digesters, designed for treating primary sludge only. The capacity of the facility was limited and additional capacity was required.
BPO staff designed and installed recuperative thickening along with improved mixing in the two mesophilic digesters.
The capacity of the system was increased by nearly 100% and the system is more stable and has a higher volatile solids degradation. The system is more easily operated and has sufficient capacity for approximately another 10 years, at very small capital expenditure.
