Reunion Island is a French-controlled territory off the coast of South Africa situated in the Indian Ocean approximately 500 miles east of Madagascar, about 120 miles southeast of Mauritius, the nearest island. Environmental sustainability is a critical issue on this island given land availability, strict European and French regulations, mountain slopes, population density and proximity to rivers and streams. The search for an ideal aeration system took more than a decade, but a solution presented itself with Aeration Industries’ Aire-O2 Triton process aerators .
For more than 40 years, CILAM (Compagnie Laitières des Mascareignes) Dairy has been involved in the development and processing of dairy products in Reunion Island, working closely with the cooperatives. The company produces milk, cheese, yogurt, ice cream and a variety of juices. CILAM, located in Saint-Pierre on the island’s southern coastline, employs 200 people from the island’s total population of 800,000.
The CILAM Dairy utilizes an activated sludge process wastewater treatment facility that serves the dairy’s processing plant. Flow into the wastewater treatment plant measures 234,585 gal per day and it is directed through four concrete basins. The average influent biochemical oxygen demand is 3,000 mg/L.
