Aluminum Sulphate Flocculant Water treatment

3.Applications:

Water effluent treatment system
It's used for purification of drinking water and wastewater treatment by settling of impurities by

means of precipitation and flocculation.

Paper Industry
It helps in sizing of paper at neutral and alkaline pH, thus improving paper quality (reducing spots

and holes and improving sheet formation and strength) and sizing efficiency.

Textile Industry
It is used for color fixing in Naphthol based dyes for cotton fabric.

Other Uses
Leather tanning, lubricating compositions, fire retardants; decolorizing agent in petroleum, deodorizer; food additive; firming agent; dyeing mordant; foaming agent in firefighting foams; fireproofing cloth; catalyst; pH control; waterproofing concrete; aluminum compounds, zeolites etc.

4. Package:

Packaging Detail: PP/PE 50kg/bag;25kg/bag;Jumbo bag or according to customers' requirements.

20-25MT will be loaded in per 20'FCL container.

5. Attention and Storage:

The product is liable to absorb moisture and clot due to long-term exposure, so shady, cool and ventilated environment is needed.

Q:Catalyst - Can it decrease the rate of a reaction?
no, by defintion the catalyst speeds up the reaction.
Q:Chemical reactions in the presence of impurities will cause catalyst poisoning
This is in the chemical balance, but also alone
Q:The quality and nature of the catalyst before and after the chemical reaction did not change this sentence wrong?
There is no wrong catalyst just to speed up the reaction
Q:What is the role of the catalyst in chemical knowledge?
The catalyst is divided into: positive catalyst and negative catalyst, positive catalyst accelerates the reaction rate, and negative catalyst slows down the reaction rate. Regardless of the positive and negative of the catalyst, it only changes the rate of the reaction, does not change the nature of the reaction, and the reaction, the chemical nature of the catalyst will not change!
Q:What is the difference between biological and chemical catalysts?
catalysts which catalyze the chemical reactions taking place in human body such as enzymes are called bio-catalyst and other one's which are generally used in laboratory by chemists for multiple type of reactions are chemical ctalysts
Q:How are a catalyst and an intermediate similar? How are they different?
A catalyst speeds up the rate of a reaction by lowering the activation energy barrier which is, presumably, the energy required to achieve the reaction intermediate. Catalysts are also not consumed in the reaction, they are regenerated towards the end. A reaction intermediate is a configuration that a molecule takes prior to achieving it's lowest energy form which would signify the end of the reaction. Intermediate usually are hard to isolate because of the incentive to go to the most stable configuration. How are they different? A catalyst is not a part of the reaction product and it doesn't get consumed. An intermediate in a reaction is transformed into the product. How are they similar? Well, catalysts drive the reaction and make it easier for the reaction for follow through. Since intermediates are high energy and thermodynamics tells us that low energy is favorable, the incentive for a high energy intermediate to drive down to it's stable for can also drive a reaction. I hope that helps. I hope it makes sense.
Q:What is the superiority of the catalyst compared to the stoichiometric reagent?
Specificity: an enzyme can only catalyze one or a class of substrates, such as proteases that catalyze the hydrolysis of proteins into polypeptides;
Q:Chemical Reactions Under what circumstances the catalyst accelerates the reaction
First, more than ninety-nine percent of the catalyst is accelerating the reaction, and if the catalyst kinetics reduces the energy barrier of the reaction, the reaction will naturally accelerate.
Q:catalyst and reagents ???
Believe me, nema, there's no way that we chemists know the best catalyst for every reaction. That would be simply impossible. However, from the type of reaction, the reactants, products, reaction conditions, solvents, etc. and from one's experience and the literature (papers and patents) one can get a good idea for most reactions of the type of catalyst that has worked for similar systems. One then starts off with a catalyst from the literature and modifies or changes it if improvement is needed based on chemical principles that one learns. There are also some theoretical calculations that can be made. Sometimes they work and sometimes they don't :) If it is an industrially important process like the Haber process for making ammonia from nitrogen gas and hydrogen gas, there may be thousands of catalysts which have been tried and evaluated. New minor improvements are being made every day. When a company does find a very good catalyst for an important reaction, often they keep it a trade secret. The good catalyst can make a huge difference in how commercially successful a particular process is. That's a large part of what chemical engineers do. You may never know if you have the best catalyst. The most you can hope for is one that is good enough. So it's a few parts personal knowledge, a few parts literature, a couple of parts theory, a lot of experimentation and often, more than not, a little luck. :)
Q:What is the relationship between the catalyst and the chemical reaction?
Catalytic, also known as catalyst, is defined in the junior high school stage to be able to change the rate of chemical reactions, and its own quality, composition and chemical properties remain constant before and after chemical reactions. For example, manganese dioxide can be used as hydrogen peroxide (hydrogen peroxide) decomposition of the catalyst. The catalyst is divided into the positive catalyst and the catalyst is used. The positive catalyst contributes to the reaction to move in the positive direction, and the reverse catalyst contributes to the reaction to move in the reverse direction.
