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.

Electronic scales often have large and small problems. When electronic scales show problems, we immediately think of weighing instruments. However, because there are many parts related to weighing instruments, we do not know what to do. In fact, when encountering electronic floor scales are not normal or even after booting, we need to do not worry, but analyze the product's possibility of error and find out where to make mistakes based on the actual situation.
(1) After the power is turned on, the electronic scale weighing instrument does not respond.
Solution: Check carefully whether the power cable is in good condition, and if the weighing instrument cable is in good condition, replace the damaged cable and replace it immediately.
(2) When the electronic scale is opened, the weighing indicator shows numbers and there is no regular jump.
Solution: In this type of problem, consider that the junction box is too heavy and should be blown with a hair dryer.
(3) Weighing results are light or heavy after normal boot.
Solution: Recalibrate the electronic scales according to the instruction manual. If the problem is still not resolved after calibration, consider that the sensor has been damaged.
(4) The figure displayed by the weighing instrument is not stable when weighing.
Solution: Check whether the weighbridge is in the horizontal plane and readjust its position.
(5) After the weighing is completed, the weighing object is removed and the weighing instrument is not returned to zero.
Solution: The above situation should be that the signal is attenuated due to line breakage. Look carefully at the electronic scale data line for damage. If so, replace it promptly. ??
