We offer Flocculent Chemicals which is used widely in various industries. These chemicals are processed and formulated in the true composition to guarantee safety during use. They are prepared keeping in mind the quality norms of the industry. We provide the customers with proper usage guidance along with the orders. You can place bulk orders with us along with a promise of timely delivery.
- Flocculants - To promote the formation of flocs in water that contains suspended solids polymer flocculants (polyelectrolytes) are applied to promote bonds formation between particles. These polymers have a very specific effect, dependent upon their charges, their molar weight and their molecular degree of ramification. The polymers are water-soluble and their molar weight varies between 105 and 106 g/ mol.
There can be several charges on one flocculent. There are cationic polymers, based on nitrogen, anionic polymers, based on carboxylate ions and polyampholytes, which carry both positive and negative charges.
- Neutralizing agents (alkalinity control) - In order to neutralize acids and basics we use either sodium hydroxide solution (NaOH), calcium carbonate, or lime suspension (Ca(OH)2) to increase pH levels. We use diluted sulphuric acid (H2SO4) or diluted hydrochloric acid (HCl) to decline pH levels. The dose of neutralizing agents depends upon the pH of the water in a reaction basin. Neutralization reactions cause a rise in temperature.
- Oxidants - Chemical oxidation processes use (chemical) oxidants to reduce COD/BOD levels, and to remove both organic and oxidisable inorganic components. The processes can completely oxidise organic materials to carbon dioxide and water, although it is often not necessary to operate the processes to this level of treatment. A wide variety of oxidation chemicals are available. Examples are:
- Hydrogen peroxide
- Combined ozone & peroxide
- Hydrogen peroxide - Hydrogen peroxide is widely used thanks to its properties; it is a safe, effective, powerful and versatile oxidant. The main applications of H2O2 are oxidation to aid odour control and corrosion control, organic oxidation, metal oxidation and toxicity oxidation. The most difficult pollutants to oxidize may require H2O2 to be activated with catalysts such as iron, copper, manganese or other transition metal compounds.
Ozone - Ozone cannot only be applied as a disinfectant; it can also aid the removal of contaminants from water by means of oxidation. Ozone then purifies water by breaking up organic contaminants and converting inorganic contaminants to an insoluble form that can then be filtered out. The Ozone system can remove up to twenty-five contaminants. Chemicals that can be oxidized with ozone are:
- Absorbable organic halogens
- Nitrogen oxides
- Odorous substances
- Chlorinated hydrocarbons
- Oxygen - Oxygen can also be applied as an oxidant, for instance to realize the oxidation of iron and manganese. The reactions that occur during oxidation by oxygen are usually quite similar. These are the reactions of the oxidation of iron and manganese with oxygen:
- 2 Fe2+ + O2 + 2 OH- -> Fe2O3 + H2O
- 2 Mn2+ + O2 + 4 OH- -> 2 MnO2 + 2 H2O
