Olive oil extraction normally results in large quantities of difficult-to-handle waste water (black water). Most municipal wastewater plants do not accept this waste, which is often spread on farmland. This is costly and not good for the environment.

Alfa Laval has developed a highly efficient, cost-saving alternative:

 BlueVap 

Black water treatment with BlueVap or AlfaFlash

BlueVap is a unique thermal separation system that turns waste water from olive processing in to clear water that sewage plants will accept, and a concentrate that can be mixed with husk for disposal.

This easy-to-operate set-up can process as much as 2,500 litres of waste water hourly, and needs no steam or cooling water. A similar process – AlfaFlash – is available for larger capacities and if a supply of steam is at hand.
