The Ministry of Environmental Protection announced on May 20th the standard for drinking water emergency protection, and proposed to reduce the amount of water intake or stop the extraction of groundwater for groundwater drinking water sources closer to the earthquake ruins. In the aftermath of heavy rains, the quake-hit areas urgently need 2.6 million tents to launch the manufacturers around you and contact the donation units!
Aluminum Anodized Sheet is one type of Aluminum Sheet which has surface anodized treatment.Aluminum anodized sheet is good in performance condition which requires high corrosion resistance.Regularly after casting the aluminum sheet,the surface of the sheet is with natural oxide film which is good to prevent the aluminum sheet from oxidation.Also the aluminum anodized sheet is with a shining surface sometimes which is good in some application which requires good surface condition.However,the anodic oxidation process is very costly and it requires lots of treatment in the wastage.Hence the cost of the aluminium anodized sheet will be higher than regular sheet as well.
Trust in harmony,we care what our clients care.We hope to bring better future for our next generation.

The extensive use of hygienic anti-epidemic agents and disinfectants may pose a threat to the water environment.
According to reports, the newly issued drinking water emergency protection standards and norms, according to the main influencing factors of drinking water sources, determine the technical measures and management measures to eliminate and control these key pollution factors, such as once the water source is contaminated, the specification must quickly adjust the water supply Treatment process, using activated carbon adsorption, advanced oxidation and other emergency treatment process. The regulations require that drinking water plants must strengthen the monitoring of effluent quality, especially the monitoring of pathogens, pay attention to the effects of coagulation and sedimentation and disinfection processes, increase the amount of coagulants, and ensure the amount of chlorine added, so as to ensure that there is sufficient residual pipe network. chlorine. The regulations also require increasing the frequency of water quality monitoring in areas where groundwater is used for drinking water and increasing organic monitoring indicators. The regulations specifically require environmental protection agencies to pay attention to the water quality safety problems of scattered shallow groundwater access wells or water sources in Luohe. At this stage, they should be pumped under the guidance of the health and epidemic prevention department or used for drinking in the Luanhe River.
