Bendigo Mining Water Treatment Plant, VIC

The Client's Needs

For safety reasons, future underground mining activity required the removal of contaminated water from historical underground mine workings.
Bendigo Mining wanted to expand their existing water treatment plant to treat contaminated mine water before discharge into a sensitive environment.
A design for a very small footprint was required as space was limited, thus making Actiflo® clarification process very suitable.

Veolia's Solution

Veolia Water Technologies Australia was awarded a contract for the design, supply, installation and commissioning of a new Water Treatment Plant. 
The plant treats up to 7ML/day of contaminated underground mine water and removes salt, dissolved iron, arsenic, heavy metals, manganese and other contaminants as well as odour (hydrogen sulphite).

Veolia proposed a treatment package including Actiflo® clarification process for pre-treatment of the feedwater.
Clarified water is filtered through Manganese Greensand Filters, coupled with upstream potassium permanganate dosing, to remove any traces of iron or manganese followed by Reverse Osmosis.

The Actiflo® high rate clarification unit combines microsand enhanced flocculation and settling.
It was sized not only for the new water treatment plant but also to provide clarified water for the existing water treatment plant.
