Water all things enough, no water worry, in the treatment of sewage, we are the most common type of purified water purification water purification material - PAC water purification agent (+ 86-15639065815), in the protection of water resources play a decisive role, Water has a long history of life, let us all cherish life together, cherish the water, attention and attention Poly aluminum chloride water purification products it.
Common Wastewater Encounters with Polyaluminum Chloride - Becomes a Variety, Next, we filter polyaluminum chloride Xiaobian to introduce the effect of several common wastewater after use, to be detailed:
A, oily wastewater treatment, we know that the general treatment of oily wastewater mainly oil separation, flotation and biochemical methods, for this wastewater treatment, the use of polyaluminium chloride and modified cationic polyacrylamide with the use of Very good treatment effect.
2. The domestic water (washing wastewater) treatment, because the water contains a lot of surfactant, and oil, dust and other particles interact to form a negatively charged colloidal particles, stable and easy to stay in the water If the amount of polyaluminum chloride in waste water, will produce a large number of positively charged cations, can make the charge suspended in the surface of the rubber particles have a strong ability to absorb electricity and electric double layer compression capacity, So that the colloidal particles destabilize, and then the pollutants adsorbed precipitation separation of water to achieve purification effect.
Third, the printing and dyeing wastewater treatment, printing and dyeing wastewater has a high COD, color and pH value, although the coagulation effect of PAC is good, but the printing and dyeing wastewater high alkalinity and poor neutralization, application Under certain restrictions, if the polyacrylamide coagulant is used in combination, the synergistic effect between the two is taken advantage of and the synergistic effect of the same ion effect. The treatment of printing and dyeing wastewater can reduce the processing cost and improve the purification effect.
Fourth, industrial papermaking wastewater treatment, PAC coagulation and sedimentation treatment of papermaking water, with the increase of the basicity of the salt, COD and SS removal rate increases, the effluent can reach the national emission standards, due to polymerization Aluminum chloride in the papermaking wastewater treatment, due to low prices, and sediment can be returned to the papermaking process as raw materials, there is no secondary pollution problems, and can produce some economic benefits.
According to the latest national standard polymeric aluminum chloride GB15892-2009, requires alumina content is 10%.
Generally speaking, there are two ways to add PAC: dry cast and wet cast; if it is dry cast, then add 0 for each ton of waste water. Then your 10% mean 10KG PAC
Acid concentration is high, you can dilute the acidity down. Can use PAC, depending on what kind of acid conditions can be judged. If it is a hydrochloric acid
Such as the choice of two kinds of flocculant and their advantages and disadvantages are present and performance of the strong and complementary, flocculation,
Therefore, the general commitment to customers in the dry and ventilated preservation of the shelf life of 1 year, we are producing this! There is no standard m
