How it works

close expand

The PuraMax Process

1. Following a primary tank, biological treatment is provided by an attached growth

process. Recycled plastic biocarriers, suspended in the tank, provide large surface

area for bacteria to attach and grow. An aeration grid supplies oxygen to the biofilm,

along with the mixing energy required to keep the biocarriers suspended throughout

the tank.

2.The mixing and the intermingling of the biocarriers sloughs excess biofilm. The

treated effluent flows through a retention screen to a clarifier for solids separation.

Settled biofilm solids in the clarifier are periodically returned to the primary tank.

3.Total nitrogen reduction is achieved through the addition of an anoxic tank and

recirculation system or by the introduction of a post anoxic tank using carbon dosing.
