Business people set up scams to sell pure water machine water challenge - pure water machine, water appliances - Network Appliance Industry
People questioned water quality Eastern Hospital of Wuhan University dormitory residents aged 62 to reflect Mr. Hu, on July 3 in the afternoon he came to the Orient Road, Hongshan District, hi Luoshi center to experience the free health physical therapy, staff to the old people selling a
Pure water machine . Staff said that the public drinking water quality and poor, by the water after filtration, water quality will be very good. Staff immediately with pure water machine water and an old man brought water from home to experiment and found that the water comes "serious exceeded."
Hu was wondering: "Is it more than 800 million people drank water in Wuhan have far exceeded?"
Electrolysis, the water become turbid 4 at noon, Hu, together with water and press to experience the center of 2 sets of them the door, "Pu Yate" pure water machine. Explained what, reporters, and Mr. Hu was invited to Manager's Office.
Soon, female staff holding TDS pen and come electrolyzer. Her to be like pure water machine water, then bring the water to Mr. Hu, tap water into the cup, respectively, start measurement. The results showed that pure water TDS value of 5, water 163, water is as high as 172 (TDS as "total dissolved solids", that the water minerals such as sodium and calcium content in the determination of the number of values).
To her, the relevant department under the drinking water TDS value should be less than 30, far exceeded its tap water. She in turn were placed in the bipolar electrolyzer water and tap water, about 5 minutes later, water became filthy and gray-green floc suspension where the water was slightly yellow.
Staff added: "Water can not say that out of the water is not good, mainly through the pipes and tanks." The Experience Center Lu Pinghua president introduced device that sets the value of 3010 yuan pure water, the inside has 4 filter.
Electrolyzer can not judge good or bad water quality Water appliances Industry, an industry, the pure water machine can rust in tap water, sediment, colloids, bacteria removed, but also to the various minerals in water filtered out of the water is pure water.
Wuhan Water Affairs Water Quality Monitoring Center of the experts explained, TDS pen and electrolyzer is used to test water quality is not good or bad, but whether it contains conductive ions detection in water. Pure water does not contain conductive ions, electrolysis of water out of almost no color change, TDS value is also small, while the tap water contains minerals, so the higher the value of TDS, will also be a variety of colors electrolysis floc.
Institute of Chemistry Central China Normal University Professor Lu Guanghan, due to a small amount of tap water contains minerals, electrolyzer power, the formation of the insoluble ferric hydroxide floc, etc..
Experts say the market with a TDS pen and determine water electrolysis device to detect good or bad, is a business selling water machine deceptive.
