HK company launches innovative system to solve water shortage

Environtech Services (Hong Kong) Ltd. on Tuesday announced the launch of a one-step turnkey Desalination and Oil & Water Separation System which can help create clean drinking water at a lower cost.

When oil is spilled into water, it disperses into tiny droplets and well mixes with water forming a stable mixture known as emulsion. The separation of oil and water from emulsion is extremely difficult and therefore causes serious damage to the environment.

For decades, industries have been looking for a cost-effective, continuous and efficient solution to remove oil from water.

This revolutionary technology not only brings a water-conscious, cost-effective and energy-efficient desalination and oil & water separation system for the oil and gas sector, but provides an unparalleled oil & water separation solution to a wide-spectrum of industries such as food and beverage, automobile or heavy industries for the transformation of polluted water into clean water.

With Environtech's patented technology, oil can be continuously separated from water through a unique process of surfactant addition, coalescing filtration and nano absorption. Oil can be removed to less than 1ppm in fresh water or 2ppm in seawater, which significantly outperforms other separation methods available at the market.

"The unparalleled benefits of our technology are extremely high quality result, energy and cost saving, and most importantly compact in size and mobility for turnkey application in different industry settings and environments," said Hao Michel Chhoa, managing director of Envriontech Services Ltd.

In the views of growing concerns over water preservation and stringent environmental regulations, Environtech's one-step turnkey Desalination and Oil & Water Separation System provides oil and gas sector a proprietary approach to treat the harmful and salty wastewater for reuse during the drilling and fracturing processes or return to the environment.

"The biggest concern of desalination has always been cost. The most commonly known method is (RO) reverse osmosis by pumping water through a membrane that does not allow salt ions to pass through. However, reverse osmosis requires a lot of space and the desalination process is limited by the rate at which water can pass through the membrane," Chhoa said, adding that unlike reverse osmosis, their system uses electro-dialysis, which requires 25 percent less space and consumes 60 to 70 percent less energy.

The system may potentially create a new drinkable water source for some of the world's driest places. For instance, the Tarim basin in Xinjiang, China is believed to possess an abundant resource of underground salt water. "Our scientists are also looking to improve the system so that it can turn brine into drinkable water," Chhoa said.

Environtech Services (Hong Kong) Ltd was established in 2012 and joined Hong Kong Science and Technology Parks Corporation's Incu-Tech Program.

"I am thrilled to witness the launch of Envriontech's Desalination and Oil & Water Separation System. The innovation of the technology is truly unprecedented bringing a good news to all mankind. I am sure there will be more revolutionary technologies gradually launching from Science Park's thriving ecosystem," Peter Mok, head of Incubation Programs, the Hong Kong Science and Technology Parks Corporation commented.
