Rendering Plant Receives New Energy Efficient Biological WWTP
September 27, 2021
Hydroflux has commissioned a new energy efficient Wastewater Treatment Plant (WWTP) for a country-based rendering customer that is achieving massive reductions in the organic and nutrient loads via treatment in a Covered Anaerobic Lagoon (CAL) and energy efficient Sequencing Batch Reactor (SBR).
The turnkey project was completed on time and involved the replacement of a conventional physical/chemical treatment plant and above ground energy intensive SBR with an in-ground CAL and SBR specifically designed to be energy efficient and to treat substantially increased flows. The CAL was selected over the previous physical/chemical Dissolved Air Flotation (DAF) process due to the significant savings in operating costs and ability to generate renewable Biogas from the high levels of COD in the wastewater.
After anerobic treatment in the CAL the wastewater containing very high nutrient levels, is treated in an ingeniously designed HySmart® Hydroflux SBR tailored specifically for nutrient removal. Greater than 90% Nitrogen removal is achieved whilst the system requires only minimal, low-cost external carbon source addition.
Even though the SBR was designed in a lined pond, best practice energy efficiency was achieved through the use of AEROSTRIP® fine bubble diffusers due to their world leading high oxygen transfer efficiency, resulting in a power demand of 1/3 of the equivalent surface aerators.
To complete the project and minimise sludge cartage and disposal costs Waste Activated Sludge (WAS) is dewatered to a very high % dry solids in a HUBER QPRESS® screw press that uses very minimal wash water and has low OPEX requirements.
