Alfa Laval’s plug-and-play technology for centrifuges achieves up to 70% water savings

Alfa Laval Optiwia is changing the game in the brewing and beverage sectors by optimising the efficient use of processed water. This innovative solution was developed in response to our customers’ drive to lower the environmental impact of their operations. It can be easily retrofitted to separators, resulting in water savings of up to 70 per cent.

Optiwia recirculates cooling water from the separator system into a collecting tank ready for reuse. The solution is robust, adjusting for changes in water pressure to ensure the centrifuge operates smoothly and maintains consistent uptime. What makes this unique is that no cooling agent or energy-consuming air-liquid chiller is needed. 

Significant costs in the water-intensive brewing and beverage industries fall into two categories: The first is related to the withdrawal of the necessary volume of water for the process, and the second concerns sending wastewater down the drain. Optiwia significantly reduces the amount of water in both cases. Water savings of around 70 per cent are already seen among customers using the product, which, for one beverage producer, equates to a savings of 458,000 litres annually.  

Filippa Kinderdal, Product and Portfolio Manager, High-Speed Separators, Alfa Laval, says: “Beer and beverage producers have long been frontrunners in efforts to preserve and reuse water. With the rise in the effects of climate change and the growing pressure on water resources, the need for optimizing water management is simply on every customer’s mind in this sector. The Optiwia offers a very simple and smart way of reusing non-contaminated water while ensuring robust operation of the centrifuge.”
