Coffee Concentration

Make it tastier Through processing, volatile aromas and flavors are lost in many industries such as the food & beverage, biotechnology, and cosmetic industries. The losses are caused by numerous factors like thermal treatments and transfer of odor compounds from packaging material. Some of those aromas and flavors are significant; however, their losses cannot be […]

Aquaporin Inside

All of our products contain aquaporins, the proteins responsible for transporting and purifying water in all living cells. Billions of years of evolution have made aquaporins super-efficient and super-selective, far better than any man-made water filter.

By incorporating aquaporins into our biomimetic membranes, we enable you to tailor-clean water faster and more energy-efficiently than ever before.

How HFFO membrane works

Aquaporin Inside® forward osmosis is a gentle process that transports water across a semi-permeable biomimetic membrane covered in a thin layer of aquaporins. As natural water filters, the aquaporins act like a super-highway, letting water pass through, while rejecting contaminants. Our membranes are highly selective, making them ideal for the production of concentrates such as coffee, fruit juice and dyes, as well as for difficult wastewater and zero or minimal liquid discharge applications.
