Polyamine based coagulants are synthesized for colour removal, turbidity, and organiccompounds from dye wastewater. Polyamine based coagulants work better than alum alone.The effects of polyamine coagulant, concentration, types, and pH on the removal efficiency ofcoloured materials were investigated.
Highly efficient colour removal was obtained by adding polyamine as a coagulant at widelydifferent pH ranges. Results indicate that the use of polyamine coagulant is cost effective indye wastewater treatment because it minimizes the amount of sludge produced as thedosage of inorganic coagulant is highly reduced.
Key Features:
Economical to use-effective at very low dosage levels.
Perform well over a wide pH range.
Easily sealable in water.
Multiple applications.
Benefits:
Use of polyamine coagulant in combination with PAC improved removal efficiency of turbidity.
PAC/ Polyamine combination was effective in reducing PAC dosage, lowering residual aluminum ion concentration in the treated water and improving turbidity removal.
High solubility.
Reduces the use of inorganic salts.
