BlueVap - Turn black water into clean water
Thermal separation system for treating black water to reduce disposal costs
Disposal of black water from olive oil extraction is an
important and growing concern for the olive oil industry
as most municipal wastewater plants do not accept it. To
resolve this issue, Alfa Laval has developed the BlueVap
thermal separation solution to deal effectively with the
difficult properties of the black water.
The BlueVap “plug and play” system turns black water
into clear water that can safely be discharged to the
local sewage plant, and a concentrate that can be mixed
with husk. The process eliminates the need for storage
or spreading in farmlands, and significantly reduces the
amount of wastewater as well as disposal costs. The unique
thermal wastewater treatment concept has proven its worth
and reliability in different types of industrial olive oil mills.
Application
The Alfa Laval BlueVap thermal separation system has been
developed for continuous treatment of black water, typically
from three-phase olive oil extraction. It is suitable for individual
olive oil mills as well as for co-operatives and is available in
capacities up to 1,000 litres/hour or 2,500 litres/hour.
Design, features and benefits
The design and operation of the pre-assembled, fully automatic BlueVap treatment system takes into consideration
the fact that many olive oil producers do not have steam or
cooling water available in their mills. This is typically required
for other types of black water treatment. BlueVap features
the most resilient evaporator technology available on the
market, building upon Alfa Laval's world-leading experience
in heat exchanger technology. The system offers high
thermal efficiency with very low electricity consumption per
kg of treated black water.
Key benefits of the BlueVap system
• Proven, reliable solution
• Low treatment costs
• Complete pre-assembled treatment unit with compact
design
• No steam or cooling water required
• High resistance to fouling
• Automatic, user-friendly operation - minimum supervision.
