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. Polyelectrolyte, thereby, plays an indispensable part
in the sludge conditioner formulation.
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.
Excellent Efficiency 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. 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.
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.
