Polyaluminium Chloride Drinking Water Treatment Chemical Additives

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, , ,

Specifications

1.PAC for water treatment
2good activenese, good fiterability.
3. treated water salinity.
4. remove heavy metals and radioa

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.

Q: Chemistry GCSE what is a catalyst?: If you just need the GCSE version (it gets far more complicated at A Level, you have to learn about activation energy and all this other crap) then it's just a substance that speeds up a reaction and allows it to happen quicker. but! The catalyst itself also remains unchanged at the end of the reaction (for reasons you probably don't need to know until A Level.) Remember that.

Q: Is it faster or slower? The What if you do not?: Positive catalyst is to speed up the negative catalyst to slow down some reaction must be used to the catalyst otherwise difficult to react

Q: in acid-catalyzed reaction,there are some books show the acid catalyst as H+ and there are some show it as H3O+ .Are they the same?: H+ is the ion contained in acids.... When acids are dissolved in water (H+)+(H2O)=H3O+ Both are the same......

Q: Also, how is the catalyst affected by heat? Please answer all of the questions not just one of the three. THANK YOU!: It denatures the catalyst because the rise in pH or amount of H3O+ ions. Temperature will also denature the catalyst if it's out of its optimum range.

Q: Is the catalyst in the field of inorganic chemistry?: In the chemical discipline, including inorganic chemistry, analytical chemistry, organic chemistry and physical chemistry and other secondary disciplines, catalytic science for the three disciplines, generally attributed to the physical chemistry of the mouth.

Q: Cl + O3 ---&gt; ClO + O2O + ClO ---&gt; Cl + O2= O + O3 ----&gt; 2O2What is the catalyst? The intermediate?How do you know which is which? If the rate law is rate=k [O3] [Cl]determine:a) the overall order.b) unit for k.c) the rate determining step, justify your answer.: Cl is the catalyst. ClO the intermediate. The catalyst is the component which does not change in overall reaction. He forms some intermediate component(s) with the reactants. In the later reaction steps the intermediate(s) react forming the catalyst in its original state. (a) The overall order is the sum of the orders with respect to the components: n = 1 +1 = 2 (b) the unit of the rate of reaction is r [=] mol/ (Ls) (more general mol per unit time and volume) compare dimensions mol / (Ls) [=] k · mo/L · mol/L =k [=] L/(s mol) (more general unit volume per unit time and mole) (c) First reaction For elementary reaction steps the order of the reaction rate with respect to a reactant is equal to stoichiometric coefficient. Hence the rate of first reaction is: r? = k?·[Cl]·[O?] Overall rate is given by the rate determining step, while other reaction steps are in equilibrium: r = r? = k?·[Cl]·[O?] If second reaction is the rate determine step r? = k?·[O]·[ClO] while reaction 1 is at equilibrium K? = ( [ClO]·[O?] ) / ( [Cl]·[O?] ) =[ClO] = K?·( [Cl]·[O?] ) / [O?] the overall rate would be: r = r? = k?·[O]·[ClO] = K?·k?·[O]·[Cl]·[O?] / [O?] = k·[O]·[Cl]·[O?] / [O?] That doesn't match the observed rate law

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: Which chemical reaction is added to the catalyst in order to slow down the reaction: Edible oil added 0.01% to 0.02% gallate n-propyl ester, you can effectively prevent rancidity
