SIL-RH
From Seawater to FreshwaterÂ
PRODUCT DESCRIPTION /Â FEATURES
The “SIL-RH from Seawater to Freshwater” serves as the core of a new ceramic hollow fiber membrane system derived from rice husk. It is able to filter 100% of salt content with high flux comparable to commercial reverse osmotic membrane (RO). Its long-term ability is excellent for operating at high temperatures and pressures without a decrease in performance.
NEEDS
Water covers 71% of the Earth's but only 1 % is fresh water that can use as drinking water. 69% is seawater which has a high concentration of salt and other contaminants such as bacteria and viruses
In Malaysia, a lot of people suffer due to the water shortage caused by a natural disaster
Around 20 % of paddy field is waste rice husk and was often burned or dumped on landfills
World demand for membrane technologies will rise 8.5% annually to 26.3 billion in 2019
APPROACH
The ceramic hollow fiber membrane was fabricated using the phase-inversion process and sintering technique.
The membrane was surface modified using the hydrophobization process thus enhanced the performance of the desalination process
The produced membrane was assembled into a direct contact membrane distillation system
The freshwater extraction was obtained by the heat and mass transfer process
BENEFITS
Estimated membraned cost: US$40/m^2 is much cheaper than of alumina membrane (US$ 500/m^2) and polymeric membrane (US$ 50-70/m^2)
COMPETITORS
Thermal treatment plant.
Reverse osmosis membrane system
