Wherever water is used, waste water is generated. This water may be contaminated with bacteria, solids and chemicals. The Waste water plant uses a set of stages to purify this water for either disposal under an approved environmental license or further treatment for reuse.
Waste is received at the asset and passes a screen to remove large solid components. The waste then passes to a screening plant for initial removal of larger suspended solids, which sink to the bottom of the system. The waste now passes to a clarification stage where the slow-moving water allows the further fallout of solid partials for disposal. This waste water is drawn from the top of this system and passes to the aerator where air is added to encourage the brake down of any organic waste (and the growth of bacteria). The treated waste water now passes to the secondary clarifier to remove the smaller solids. As bacteria remain in the waste the next stage disinfects the water by UV, Ozone or Chlorination. Finally, the cleaned water is checked for chemical composition which may be corrected to meet the plants output specification.
