High performance Flocculation with Polyelectrolyte

Polyelectrolytes are designed to be used as coagulants and flocculants as well as a sludge dewatering agent in the waste water treatment plants. Polyelectrolyte, thereby, plays an important part in the sludge conditioner formulation. These are referred to as polymers that are generally used for water purification. It is highly noted for its beneficiary nature of handling problems of slow settling of flocs in water at low temperature, treating soft colored water where they increases toughness of the flocs and enhance its settlement ability.

Generally flocculation occurs owing to charges present on the particles. Generally, Polyelectrolyte can be differentiated into 3 types based on the charge present on it. These are Non-Ionic Polyelectrolyte, Anionic Polyelectrolyte, and Cationic Polyelectrolyte.  In practical cases, charges are present on the impurity particles and electrostatic interaction occurs between these particles and polyelectrolyte.



Chemtex Speciality Limited manufactured product Polyelectrolyte serves as a strong cationic radical polymer based coagulant that has been specially designed for complete or partial settling of water soluble matters, organics, and suspended solids in the effluent water through electro neutralization and bridging absorption. Bridging absorption takes place when long chain polymers get absorbed on the particles in a pattern such that it forms loops and tails extending some way in the solution. At this stage, particles are said to be re-stabilized. Absorbed amount must be optimum otherwise enough bridging contacts could not get formed. This consideration leads to the need for an optimum dosage of the product for formation of bridging flocculation.

High performance Flocculation with Polyelectrolyte is a well known function of this product that is offered by Chemtex Speciality Limited. It acts as a decolorant, and is effective in algae growth inhibition and organics removal. It can completely replace Alum or PAC. It usually enjoys a small dosage but can be responsible in causing big flocs, low turbidity residues and rapid precipitation. Polyelectrolyte can be safely used for the disinfection of potable water. It finds applications in variable sectors such as water treatment, mining, cosmetics, textiles, soil treatment, paper making, oil industries, etc.

How RO Antiscalant works?

  Reverse Osmosis technology provides an efficient and reliable method for purifying water for various purposes). It can remove impurities such as salts, minerals, and other contaminants as well as microbial contaminants from the Membrane. Water molecules pass through RO membranes despite dissolved solids and other contaminants being rejected by the membrane. RO membranes are basically thin, dense, and semi-permeable membranes. However, the major significant challenge in Reverse Osmosis System is Scaling. Why does it happen? The formation of scales on the RO (Reverse Osmosis) membrane is primarily caused by the presence of certain dissolved minerals and salts in feed water. Scale refers to the accumulation of mineral deposits, such as calcium carbonate, calcium sulphate, and silica which can severely impact the efficiency and the lifespan of the RO membrane. RO Membrane scaling may lead to cause ·          Excessive Energy Consumption...

Hybrid Organic Acid Technology (HOAT) Coolant

Optimal use of machines is directly proportional to its engine performance. What an engine does is it converts the supplied energy into its mechanical form, driving the machine to work. Engines require one-third of total heat that is generated during conversion and the rest of the heat is needed to be evacuated from the combustion chamber which would otherwise lead to engine failure. Earlier, water was preferred as an ideal coolant for quite a period of time but the problem started to arise when the temperature would become extremely high or low, to be precise temperature more than 100 ° C and below 0°C. To get rid of this problem, coolants were formulated. Coolants are categorized chemicals that increases the boiling point of the fluid and decreases the freezing point of the fluid to make it suitable for use in extreme heat and freezing conditions. Coolants are a proportionate mixture of antifreeze and solvent, mainly glycol and water. Ideally utilized as a preventive in...

Excellent Efficiency Flocculation with Polyelectrolyte

Polyelectrolytes are regarded as polymer chains with an electrolyte group on every repeat unit. When dissolved in a polar solvent, these polymers are charged due to dissociation of small counter ions that leave behind a charged macro ion. Polyelectrolytes include biologically important molecules such as polypeptides and DNA. These are referred to as polymers that are generally used for water purification. These are highly noted for their beneficiary nature of handling problems of slow settling of flocs in water at low temperature, treating soft colored water where they increase toughness of the flocs and enhance its settlement ability. Polyelectrolytes are formulated in a way so as to be used as coagulants and flocculants as well as a sludge dewatering agent in the waste water treatment plants. P olyelectrolyte , thereby, plays an indispensable part in the sludge conditioner formulation. Generally flocculation occurs owing to charges present on the particles. Generally, Pol...
