Water contamination in China’s major cities is a serious concern for its dense populations, making it a basic necessity for households to find ways to ensure that the water coming through their taps is fit for domestic use.
Now, various new, simple-to-use and even inexpensive technologies that monitor and control water quality in residential roof-top water tanks have entered the Chinese market, making it easier for the residents of Shanghai, Beijing and other highly populated cities whose water sources are prone to contamination to rest assured that the water at home is safe for use not only for hygiene but also for drinking and cooking.
It has been widely reported that many of China’s cities have highly polluted waterways due to industrial waste pollution, making domestic water vulnerable to industry-produced chemicals. Pollution is a serious concern in Beijing, leading China to develop a new plan to improve that situation over the coming years, according to a Reuters report. And earlier this year, thousands of pig carcasses were found floating in the Huangpu River, Shanghai’s main water source for drinking water, posing a serious health hazard for residents.
As such, residents and visitors to China are mostly advised to use tap water for hygiene only and to use bottled or boiled water for drinking, the former being a major expense and the latter a serious inconvenience.
So how can China’s city-dwellers make their tap water fit for consumption despite the unpredictable quality of the water?
Many of the cities’ residential buildings and towers supply domestic water to homes via rooftop water tanks, and in some areas the water is heavily chlorinated for disinfection, making it unpleasant to use. Besides the problem of municipal-sourced contamination, water tanks can develop mold or bacteria from foreign organisms, such as bird droppings and even dead fowl. They might be emptied, inspected and cleaned only once every year or two, while it takes only one day for water to become contaminated or for its chlorine levels to become unbalanced and unfit for home use.
So an efficient and cost-effective way for residents, hotels, and office buildings to continuously monitor the water quality is by installing a water analyzer and controller on-site, such as the Prizma, which is a patented technology developed by Blue I Water Technologies. This particular solution uses a special and innovative electro-optic test strip technology for monitoring and controlling the water’s chemical levels, such as chlorine and pH. This system is set to automatically test the water in the residential tank at regular intervals (usually once a day) and assures chemical balancing for the water. It is automatically calibrated and alerts management of inadequate disinfection in real time via online reports, allowing for a prompt response to the problem. Intended for residential use, maintenance of this technology only requires switching its test strip cartridge and does not involve training or technical know-how. The electro-optics give accurate and repetitive reading of the test results, which are transmitted to the user with a remote status report via cell phone, SMS or Ethernet.
“While solving the problem of water contamination might have become a national mission for China, residents still cannot always know whether the water coming into their taps from municipal and national systems is fit for use at all times. They need to have low-cost solutions such as this one to ensure that their home water is clean and safe for use and to feel that they have that under control,” says Stela Diamant, Chief Technology Officer for Blue I Water Technologies, who is exhibiting Blue I’s range of technologies for residential, municipal and industrial water quality monitoring at the Aquatech international water show in Shanghai this week.
“A small investment in monitoring the water coming from the rooftop tank with the latest in automated systems is probably well worth it to avoid the distress of finding out about a severely contaminated water supply after using it,” adds Blue I Water Technologies CEO Jacob Azran.
Blue I Water Technologies can be visited at the Aquatech China show at the Shanghai World Expo Exhibition & Convention Center this week, 5-7 June, booth 3.051.For more information:

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
