Following the recent reports on water pollution, Chinese people pay more attention to water quality. It has become fashionable to spend money on health, and the sales of water purifier products are warming up rapidly. However, due to the lack of consistent national mandatory norms, there are doubts about the uneven quality of domestic water purifier shopping malls. Yesterday, the cleaning Supervision Bureau of Chongqing Cleaning Bureau released the results of inspection of domestic small water quality processors (mainly activated carbon) in 2013, which showed that 50% of clean water equipment was not up to standard.

Recently, the Cleaning Supervision Bureau of Chongqing Cleaning Bureau inspected six brands of clean water equipment. In the meantime, three batches of clear water products, Vatti Huadi HD-RO-13 water cleaner produced by Zhongshan Chuangneng Electrical Appliances Technology Co., Ltd., Jiuyang JY-UF-CF311 water cleaner produced by Hangzhou Jiuyang Clear Water System Co., Ltd., and 3M CDW2201 water cleaner produced by 3M Data Skills (Guangzhou) Co., Ltd., were qualified.

The number of colonies in the effluent of the water treatment equipment manufacturer whose tap water passes through the water quality processor at 2.00m3 does not meet the requirement of GB5749-2006, which is produced by Gusu Lisheng Clean Water Technology Co., Ltd. Kunshan General Xin Machinery Co., Ltd. has a batch of MUL-130G full active reverse immersion water purifiers which are not qualified. The total number of colonies in the effluent water quality of 0.00m3 and 3.60m3 of tap water through the water quality processor does not meet the requirements. Kunshan Yikou Clear Water System Co., Ltd. failed a batch of Yikou 800FFDC type direct drinking water purifiers. The total number of colony in the effluent of 1.00m3 effluent of tap water passing through the water quality processor did not meet the requirements. According to the Cleaning Supervision Bureau of Chongqing Cleaning Bureau, this will bring serious danger to consumers'drinking water safety.

"The production standard of household water purifier needs to be improved and strengthened." Yesterday, professor of household appliances on the home appliances expenditure network showed that at present, domestic water cleaner products market space is large, profitable, low career threshold, many manufacturers flourish into. The question is that the quality of products is not uniform, even some well-known professional brands are also questioned.

It is understood that the reason for the mall disorder is the lack of a consistent national standard for domestic water purifiers. From the existing standards, several professions are formulating specifications for water purifiers, and even several depart from formulating specifications for the same product. For example, RO (reverse immersion) water quality processor (RO water purifier), Ministry of Housing, National Oceanic Administration of Reverse Osmosis Pure Water Equipment, Ministry of Cleaning and Ministry of Environmental Protection have their own professional specifications (or specifications), and GB/T 19249 national specifications. There are five specifications for the same product. Nowadays, with the approval of the Light Industry Machinery Standardization Skills Committee, American companies and others are taking the lead in formulating the national norms for RO water purifiers; Home Appliances Standardization Skills Committee and Qinyuan Company are taking the lead in formulating the professional norms for RO water purifiers. In this way, the household water cleaner shopping malls are confused, lack of technical standards and guidelines, and the rights and interests of consumers can not be guaranteed.

Some professors also showed that the raw materials used in the water purifier, the filter data used and the related parts and components were not in accordance with the standard. This will lead some companies to produce water purifiers from cheap and inexpensive raw materials to reduce costs and quotations. And the key parts of the water purifier, such as the production of filter elements, lack of consistent specifications, consumers can not be ensured in the after-sales service, not only the scale is difficult to match, but also very simple in different filter element quotations by bad companies fraudulent.

The responsible person of China Consumer Association indicated that when purchasing clean water equipment, consumers should read the instructions carefully, pay attention to parameters such as clean water flow, additional total clean water flow, applicable water pressure and primary filter material, and then consider factors such as the cost of replacing filter element, such as service life and selling price, to select good brand and performance. Products with high quotation ratio.

Connection: total number of colonies

The total number of colonies indicates the cleaning status of food. The more water treatment equipment in Hangzhou, the faster the erosion and transformation of food. Overexpenditure of the total number of colonies can easily make the products decay and degenerate in a short time, and then lose the edible value. Consumers who consume food with excessive colonies can cause infectious food poisoning and toxin food poisoning. The common clinical symptoms are abdominal pain, diarrhea and other acute gastrointestinal diseases, which damage human health and safety.
