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:

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
