RFLOC FLOCCULANTS are water-soluble homopolymers and/or copolymers of Acrylamide and Acrylamide and Acrylic Acid.
These polymers are being used extensively
as flocculantes due to their excellent flocculating properties in very small dosages. The flocculent are used to increase the state of aggregation of suspended solid particles and thereby facilitate seperation of solid constituents from liquid by process such as sedimentation, filtration, floatation and Centrifugation.

RFLOC FLOCCULANTS can either be used alone or in conjunction with inorganic primary coagulants like
Alum, Iron salts & PAC and they exhibit exceptional flocculation ability in variety of solid-liquid systems with
reduced dose of inorganic coagulants.
SELECTION OF FLOCCULANT
An efficient flocculent testing program is essential for successful treatment of any suspension so that the
most efficient flocculent at the lowest possible cost can be made available. Using a simple, straightforward
laboratory method, the full range of RFLOC FLOCCULANTS can be surveyed in a jar test evaluation
(clarification tests). If necessary, these clarification tests can be supplemented by thickening and filtration

MECHANISM OF ACTION
The coiled structure of these straight chain polymers straighten out on their addition to water, resulting in
formation of viscous to highly viscous solution, depending upon their ionic nature, charge density on chain
length and molecular weight. This solution when added to the suspension to be treated, instantly induces
flocculation by Bridging Mechanism.
The optimum effective flocculants dose largely depends on the solid content and the nature of slurry.
Normally the optimum dose varies from 0.1 PPM to 5 PPM.
Again, it is stressed that for maximum efficiency and economy, the flocculants should be added as very
dilute solution, in staged amounts, to locations where the suspended solids will be thoroughly mixed with
the flocculants. Intense agitation must be avoided.
Care should be taken to avoid excessive dose as the same can produce phase inversion resulting in poor
or no settling.
SAFETY & HANDLING
RFLOC FLOCCULANTS are non toxic but care should be taken to avoid inhalation and ingestion. In case of
irritation at any contact part, flush it with large volumes of water and medical advice should be taken.
Spillage should be handled in dry state whenever possible as the wet state or solution provides very slippery
surface. Addition of salt or sand and their removal in dry state is recommended before washing the
surface. Gloves are recommended particularly for handling jelly.
RFLOC FLOCCULANTS should be stored in airtight packing to avoid contamination of moisture.

Poly aluminum chloride in all form, is extensively used as an industrial coagulant and flocculent in different industries. Different grades of PAC are available for different purposes. These are basically two grades.
1)PAC - Basic aluminum chloride
2)PAC - Poly aluminum chloride
PAC products are used in water treatment for removal of suspended solod (turbidity) and other contaminants such as natural organic matter from surface water, micro- organisms and coloidal particles, slit and clay are stabilized by surface electrostatic charges preventing the particles from coalescing. It is advantageous in water of low to moderate turbidity, possibly because of there greater charge neutralizing capacity relative to alum.
