Forward osmosis - the most frequently asked questions

Forward osmosis is increasingly being used in a range of water treatment applications, from food and beverage production to heavy industry. Here are answers to a few common questions about the process.

Where are hollow fiber forward osmosis membranes used?

Naturally pure or with a touch of yeast – how do you like your water? From brewing to microelectronics, our Aquaporin Inside® water filter membranes are improving water re-use in a wide range of industries and applications. Here are some of the great things our customers are doing with our membranes.

Semiconductor Waste Water

Semiconductor wastewaters are inherently difficult to treat. They are usually characterized by strong color, high COD, high levels of VOC and heavy precious metals. Conventionally, chemical coagulation and biological treatment are used to treat wastewater before discharge. Diminishing freshwater supplies and growing concerns on the environmental impact from industrial wastewater discharges have propelled Zero Liquid […]

The need for better dye concentration

The dye manufacturing industry will benefit from adopting new technologies to address strong global demands for higher quality dyes and deal with the ever-increasing stringent wastewater discharge regulations. Forward osmosis is a novel technology that can potentially be the solution to meet this challenge. A decade ago, nano-filtration (NF) and reverse osmosis (RO) replaced conventional […]

Leachate Treatment

Landfill leachate condensate concentration using Aquaporin Inside® hollow fiber FO Landfill leachate production is a persistent global environmental pollution issue that is difficult to solve. This is due to its’ inherent high pollution load and varying composition depending on the ‘waste age’. Regardless of the method used, treatment is usually expensive. When left untreated, leachate […]

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.
