Polyaluminium Chloride PAC for Water Treatment

Description:

PAC( Polyaluminium Chloride) is high efficient, cheap and nontoxic inorganic high molecular compound.

The solid is yellow powder. It is easily soluble in water. In the hydrolytic process, it is accompanied with the chemical

processes such as electrochemisty, coagulation, absorption and precipitation. The product has the features including wide applicable range of pH value, large granule and quick speed in sedimentation. It is widely applied for treating the

drinking water, industrial water and daily sewage etc, , ,

Polyaluminium Chloride PAC for Water Treatment

Application:
Polyaluminium Chloride PAC is mainly used as the flocculating agent for the treatment of drinking water and industrial waste

water(such as oil waste water, printing and dyeing water and pulping waste water), and it is also applied in the treatment of

high toxicity heavy metal and F-containing waste water; Morever, it is also widely applied in precise casting, paper-making,

tanning and other industries.

Main characteristics:
1. The flocculation body takes shape quickly, good activenese, good fiterability.
2. PAC is suitable for wide adaptability, pH value, used widly.
3. PAC treated water salinity.
4. PAC can remove heavy metals and radioactive substances in water pollution.

Q: Why the amount of catalyst is too small will make the chemical reaction rate slowed down: The catalyst changes the reaction rate by changing the reaction pathway and reducing the activation energy of the reaction.

Q: Does a catalyst work for both reactants and products?From my understanding, organic catalyst or enzyme does not necessarily work for the product of the reaction because of the shape of the activation site. However I cannot speak for inorganic ones.: A catalyst works for either the reactants or the product in a given reaction. If it works for the reactants then the activation site on the enzyme, for example, will only fit on the reactants. If a catalyst is added to a reaction in which it catalyzes the back-reaction, or it aids the products, then the reaction will be reversed. i don't think a catalyst could work for both the reactants and products in one reaction because it wouldn't really be a catalyst anymore; it wouldn't make the rxn progress any faster since it would be canceling out itself by aiding both the reactants and the products. I think this is what you are asking, if not please post more details. I hope I didn't confuse you even more!

Q: why is palladium/platinum a good catalyst?: Palladium and platinum can form partial bonds with other molecules. By forming these partial bonds, the bond in the actual molecule gets weaker and weaker and hence, the bond becomes easier to break. Let's say for example a hydrogen molecule. There is a single bond between the 2 hydrogen atoms. Platinum/palladium will form partial bonds with the 2 hydrogen atoms. By doing so, the single bond BETWEEN THE 2 HYDROGEN ATOMS gets weaker and weaker. Hence, a smaller amount of energy is needed to break the bond between the 2 hydrogen atoms (the hydrogen molecule). As the amount of energy needed to overcome the bond between the 2 hydrogen atoms gets smaller, we say the activation energy for the reaction has been reduced. Hence, a greater amount of bonds in hydrogen molecules can be broken in a smaller time, and therefore, we say palladium/platinum has catalysed the reaction.

Q: Like biological and industrial reations. Thanks.: Reactions that have high Activation Energy need catalysts to speed up reactions. These reactions aren't spontaneous since the reactants do not have enough energy to overcome the activation energy barrier. Catalysts are compounds that speed up reactions by providing an alternative pathway for the reaction. It is a common misconception that catalysts lower the activation energy. It doesn't actually lower the activation energy, instead it provides an alternative pathway with lower activation energy. For example, breakdown of hydrogen peroxide happens in nature but, relatively slowly. When you add a little bit of manganese dioxide, the breakdown happens a lot faster. Another example is, breakdown of glucose in the body. It is facilitated by an enzyme called amylase (or carbohydrase). An industrial example is the use of vanadium pentoxide (V2O5) in the Contact process, where SO2 is converted to SO3 in the presence of V2O5. Hope that helps!

Q: what is a catalyst ?: catalyst is a substance that can cause a change in the rate of a chemical reaction without itself being consumed in the reaction; the changing of the reaction rate by use of a catalyst is called catalysis. Substances that increase the rate of reaction are called positive catalysts or, simply, catalysts, while substances that decrease the rate of reaction are called negative catalysts or inhibitors.

Q: I dont know what it is but when i open up my computer it comes up and it says that its not working? so i really dont know what to do.: ATI Catalyst Control Centre is a control program for ATI graphics cards. If you have an ATI graphics card, go to the ATI website and download and reinstall the program.

Q: To write a 1500 words of small papers, so please help you busy: Change the course of the reaction

Q: i know that the catalyst is not react in an reaction,,,so that i don't why could it speed up the reaction?? Further, how does the scientist determine the catalyst for certain reaction??please give me more example....i really want to know it! i do not have any idea about this...so hope your answer will help me....thanks!: Normal reaction requires much heat and energy but a catalyst provides a space where it can be done without either since provides space for both to bump into each other and stay till they bond..so catalyst is not involved in reaction but allowed it to occur at a much lower temp and energy.

Q: What is a chemical catalyst?: A substance that participates in chemical reactions but does not change the quality and chemical properties. It can change the reactant activation energy, speed up or slow down the reaction rate.

Q: In the presence of catalyst, KCl is produced in the thermal decomposition of KClO3.You did not have a catalyst. Did you get the same products for this reaction as you would have with a catalyst?: A catalyst changes the RATE of a reaction, not the products. So, yes, you get the same products without the catalyst as you do with the catalyst.
