The site operated a DAF clarification system without any effluent balancing. It is a rural site adjacent to a highly sensitive river, with no access to a public sewer. As the facility expanded and daily effluent production reached 400 m3, it became essential for the site to undertake full on-site treatment of their effluent.
In 2006, CAP installed a system involving improved raw effluent screening, effluent balancing and biological treatment to enable treated effluent to be discharged into the river.
To ensure the integrity of the system, comprehensive on-line monitoring of treated effluent and an automatic divert system was provided. In emergency situations, the site can now hold up to 3 days production of effluent before factory operations are compromised.
