Since the official launch of the water-gas-electricity collection and copying pilot project in September this year, State Grid Fuzhou Power Supply Company has attached great importance to and actively connected with it. It has communicated with the Fuzhou Economic and Information Technology Commission, Fuzhou Water Supply Company, and China Resources Gas Company several times, and finally won the government. And the other company's support and cooperation. At the end of October, the division determined the water and gas gathering and copying pilot communities of about 2,300 residents in the two communities of Jinhui Swan Bay in Cangshan District of Fuzhou City and Hongxing Court in Taijiang District. In November, the company officially conducted research and development of collection equipment.
During the development of the acquisition equipment, the Fuzhou technicians overcame the complex and unconventional communication protocols of the on-site water meter collection. After completing the research and development of the program in early December, the company started the first equipment in the site of Building 9 in Swan Bay. Test installation and commissioning. The commissioning process involved the convergence of marketing systems, acquisition systems, and meter equipment. After three days of close connection and perfect procedures, a total of 136 water meters and concentrators in Building 9 of Jinhui Swan Bay were successfully accessed on December 9. The electrical information acquisition system finally realized the successful online implementation of the data acquisition system. With regard to the remaining users' access work, the company plans to fully complete the installation and commissioning of the Swan Bay water meter concentrator by December 20, ensuring that the State Grid Corporation will complete the task within the year.
Chromium(III) sulfate usually refers to the inorganic compounds with the formula Cr2(SO4)3.x(H2O), where x can range from 0 to 18. Additionally, ill-defined but commercially important "basic chromium sulfates" are known. These salts are usually either violet or green solids that are soluble in water. It is commonly used in tanning leather.
Since 33% of the anion charges are due to hydroxy ions the basicity is 33% (but in tanning jargon it is known as 33% reduced). Products with higher basicities, e.g. 42% or 50% may be obtained by the addition of sodium carbonate, these are often used in combination with Sodium Formate. The sodium sulfate is often left in the technical product since it is inert with respect to the tanning process. It is important to fully reduce the hexavalent chromium to trivalent since the hexavalent is more likely to cause health problems for tanners and leather consumers.
