Flocculation and coagulation treatment chemicals are used in effluent water treatment processes for solids removal, water clarification, lime softening, sludge thickening, and solids dewatering.
Coagulants neutralize the negative electrical charge on particles, which destabilizes the forces keeping colloids apart. Water treatment coagulants are comprised of positively charged molecules that, when added to the water and mixed, accomplish this charge neutralization. Inorganic coagulants, organic coagulants or a combination of both are typically used to treat water for suspended solids removal.
When an inorganic coagulant is added to water containing a colloidal suspension, the cationic metal ion from the coagulant neutralizes the negatively charged electric double layer of the colloid. Much the same occurs with an organic coagulant, except the positive charge most commonly comes from an amine (NH4+) group attached to the coagulant molecule. ChemTreat has both NSF-approved and GRAS-applicable coagulation products. Examples of ChemTreat coagulants include aluminum salts, iron salts, and polyelectrolytes.
Flocculants gather the destabilized particles together and cause them to agglomerate and drop out of solution. Examples of ChemTreat flocculants include low, medium, and high molecular weight polymers.
At GPC Clear Solutions Limited, we aim to offer the best quality coagulants at competitive prices. Our range of coagulants includes:
- Organic primary coagulants (including polyamines and PolyDADMACS)
These are high cationic charged products that are needed to de-stabilise the negatively charged colloidal particles and they promote rapid floc formation. They also have low molecular weight and viscosity to ensure complete distribution and mixing of the polymer in the water. Organic primary coagulants are available in 25KG kegs or 1000 Litre IBC containers.
- Inorganic primary coagulants
These include a wide range of PAC based products, Ferric Sulphate and Ferric Chloride. Inorganic primary coagulants are available in IBC containers or by tanker delivery.
- Inorganic/organic primary coagulant blends
We can supply a range of inorganic/organic blended coagulants that can effectively treat a wide range of industrial effluents. They are all less pH dependant than inorganic coagulants and produce lower sludge volumes. The products can be dosed, undiluted as a single treatment or in conjunction with a flocculant to produce flocculation. Separation can be either by flotation or settlement. These blends are available in 25KG kegs or 1000 Litre IBC containers.
