The Chatoyer Biological treatment system provides companies with a cost effective, low maintenance option of treating waste water discharges from industrial and manufacturing facilities that contain high BOD loadings.

Many Australian companies vastly exceed the maximum allowable discharge levels.Our PTB Biological Treatment system can provide BOD reduction to less than 300, and generates no odor and minimal amounts of sludge. By utilising additional activated sludge systems and Ultra Filtration technology, water re-use options can be explored.

Photosynthetic bacteria (PTB) are characterised by their ability to assimilate carbon dioxide and consume molecular nitrogen, utilising solar sources of energy.

Common applications for biological treatment systems are:

• Industrial waste water sources such as food and beverages
• Small industrial estates
