- Description: Westland Milk Products wastewater upgrade
- Location: Rolleston, Canterbury
- Project type: Design, build, install and commission
Following the addition of a UHT plant, three Model 200 Aerofloat DAF units with a total capacity of 800m3/day were installed to improve the treatment of wastewater generated on site before discharge to sewer. The compact nature of the Aerofloat DAF was ideal for expanding treatment within the existing plant footprint and the system has been configured for traditional acid dosing as well as for acid plus DairyFlox coagulant.
