Dissolved Air Flotation Technology Nearly Doubles Treatment Capacity

Faced with a tight capital budget, a city in British Columbia required a new design for a water treatment plant capable of a maximum daily water production of 21 MPG during peak demand periods, with an ultimate demand of 29 MGD. The city was advised to rely more heavily on a nearby creek, which had poorer water quality but could meet the plant’s future water supply.

The Leopold Clari-DAF® system was installed, which provides the flexibility to treat both the creek at any time of year to the desired water quality levels.

The cost-effective retrofit achieved the highest benefit-to-cost ratio at lowest life cycle cost and should meet the projected water demand for the next half century without infrastructure improvements.
