Modern Water is the world-leader in Forward Osmosis (FO) based desalination and forward osmosis as a pre-treatment to reverse osmosis. The company successfully developed, tested and commercialised the process, with plants in Gibraltar, Oman and China. This patented process utilises the properties of forward osmosis, which has low fouling characteristics (particularly important in challenging feedwaters) and the unique advantages of a recirculating osmotic agent acting in conjunction with the double membrane barrier between the feedwater and the product water.

EXAMPLE APPLICATIONS

  • Challenging feed waters
  • High recover Desalination
  • Seawater desalination
  • Potable water supply
  • Agricultural water supply

ADVANTAGES

  • Inherently low fouling
  • Low energy requirements
  • Low chemical consumption
  • High Availability
  • Reduced product boron levels

CASE STUDY

In 2017 Modern Water (MW) worked with Hangzhou Water to deliver a 500m3/day Forward Osmosis (FO) system for desalinating seawater to produce potable water. This was incorporated into an existing water treatment facility at Shengsi Seawater Desalination Base on Sijiao Island and was commissioned in 2018. Modern Water (MW) has also delivered two forward osmosis desalination plants for the Public Authority for Electricity and Water (PAEW) in Oman in 2009, at Al Najdah and Al Khaluf.
