Feasibility study of wastewater treatment and reuse
A leading producer of grape alcohol and tartrate products from winery wastes
Treated water is used to irrigate local vineyards and pasture + replace use of mains water in Tarac’s processes
Costly mains water used for the site production processes + steam generation + cooling
Transport logistics and cost of transporting wastewater to the NPEC treatment plant on an adjacent site
PROXA was engaged to undertake a Feasibility Study to:
- Review the operation of the existing NEPC wastewater treatment plant.
- Investigate the potential to increase the quantity of treated water for reuse on site.
FEASIBILITY STUDY OBJECTIVES
- Establish the treatment capacity of the existing WWTP.
- Develop an analysis of the existing system.
- Identify opportunities to recover and reuse 600 kL/day of treated water.
- Identify opportunities to improve solids management, site water balance management and saline water management.
- Improve solids removal from the wastewater before it leaves the Tarac site.
- Improve operation of the primary (anaerobic) treatment process.
- Improve operation of the secondary (aerobic lagoons) treatment.
- Upgrade the existing MF/RO plant to increase the volume of water that can be recycled for Tarac’s use.
