Poly Aluminium Chloride is referred to as PAC. It is also commonly called basic aluminum chloride or coagulant. It is a new type of high-efficiency inorganic polymer flocculant. Its aqueous solution is a hydrolysis product between aluminum trichloride and aluminum hydroxide, with a colloidal charge, so it has a strong adsorption on suspended matter in water. To achieve the purpose of condensing suspended matter in water. The Polyaluminium Chloride produced by Jinhe are white, yellow or light yellow powder.
Polyaluminum Chloride has the functions of removing suspended matter, COD and BOD, degreasing, decoloring, removing heavy metals and residual chlorine in water, etc. It is mainly used for purification treatment of tap water and industrial wastewater. Polyaluminum chloride is currently the most widely used inorganic coagulant in water purification processes. There is no need to adjust the pH value of the source water, it has a wide range of adaptation to the pH value of the source water, which is unmatched by traditional inorganic low molecular coagulants.
Polyaluminium Chloride is used in metallurgical, electric power, tanning, medicine, printing and dyeing, papermaking, chemical and other industries` sewage treatment.It`s also used in tap Water Treatment. Its coagulation effect forms flocs (also known as alum flowers) fast, the particles are large and heavy, and the sedimentation is fast. The applicable PH value ranges from 5 to 9, and has the characteristics of low dosage, low cost, high activity, convenient operation, wide adaptability, and low corrosion.

The National Natural Science Foundation of China is an important component of the national innovation system and represents the highest level of natural science research in China. Zhejiang Provincial Institute of Metrology "Study on the Mechanism and Method of Gas Flow Sensing Based on Coated Fiber Bragg Grating Arrays" as the 2012 National Natural Science Foundation project has emerged from the hundreds of thousands of declared projects in the country and has been approved. This is the first national-level scientific research project that was approved by the Zhejiang Institute of Metrology for the support of the National Natural Science Foundation. It is also the first National Natural Science Foundation project of Zhejiang Quality Supervision System.
During the implementation of the project, three master graduate students were jointly cultivated, 5 SCI journal papers, 2 EI international conference papers, 1 core journal paper, and 4 granted patents (another 4 invention patents are still in the application stage).
The completed project is widely used, for example, in the field of energy measurement, monitoring pipeline natural gas flow, achieving energy saving and consumption reduction, and improving economic efficiency; it can help the medical technology field and achieve accurate monitoring of gas flow in the medical industry for respiratory diagnosis and atomization inhalation. And drug delivery measurement; In addition, due to high measurement accuracy, light weight, small size, can be used as a small gas flow sensor, used in manned space, lunar exploration, high-energy accelerators and other fields, has broad application prospects and social and economic value.

The first National Natural Science Fund Project of Zhejiang Institute of Metrology successfully completed
[China Instrument Network Instrument R&D] Recently, the first National Natural Science Foundation Youth Science Fund project undertaken by the Zhejiang Institute of Metrology and supported by the “Study on the Mechanism and Method of Gas Flow Sensing Based on Coated Fiber Bragg Grating Arrays†(Grant No.) carry out. This project combines many disciplines and is highly innovative. It is a frontier project of international academic research and has important theoretical research value. Its greatest advantage is that it can adjust the measurement sensitivity and measurement range online to maximize the sensing performance and break through the limitations of traditional flow sensors.
