Anox Kaldnes Inc.

ANOX  is an Australian company formed more than 5 years ago by Bobby Rimmer to supply specialised wastewater screens to the industrial and municipal wastewater markets.

Over this time, ANI has sold many screens in Australia and internationally particularly into Asia and China.

Over the last few years ANI has broadened its ability to service its markets by being able to supply a range of specialised wastewater treatment equipment competitively priced and of high quality.

ANI  has an international network of representatives, with sales to Europe, Asia, South America and in the United States of America.





BENEFITS

High separation and sludge thickening efficiency
High air dissolving rate (>90%)
Reduced energy and chemicals consumption
Low water head of the flotation cell
Smplified and easy installation
Can retrofit to existing circular tanks
Optional fully automatic operation
Know-how for implementing the flotation unit in the WWTP or in the production line
PRINCIPLE OF OPERATION

Feed stream, clarified effluent and sludge float are all conveyed through the unique multi functional central column. Both feed and clear streams follow uniform radial trajectories through different sections of the liquid volume in the cell. The feed mix, is pushed immediately to the surface due to the floating action of the micro air bubbles. Thanks to the specifically designed inlet slots, the inflow is distributed uniformly throughout the flotation area (hydro direct system).

Before reaching the exit slots, the clear bottom layer is forced to pass through a filtering micro bubbles bed provided by the high efficiency air-dissolving reactor. This unique system allows for an extra available flotation area and separation performances superior to any other DAF units currently in the market.

A radial skimmer with a rotating double scoop removes the sludge float continuously without disturbing the sludge blanket.
