Polyamines

A polyamine is an organic compound which consists of two or more primary amino groups. This class of compound includes several synthetic substances that are important feed stocks for the chemical industry.

Characteristics

The appearance of this product is a clear solution with a yellow to amber colour.

Properties and Application

  • Synthetic organic coagulants with molecular weights ranging between 10,000 and 100,000.
  • Is used mainly in potable water clarification as either a primary coagulant or coagulant aid to metal salts, such as ferric chloride.
  • It performs over a wide range of turbidities and pH levels and is particularly suited to exceptionally high turbidity conditions. As turbidity decreases it will in general revert to a coagulant aid role.
  • Effective clarification of low turbidity water is achieved in sludge blanket or sludge contact clarifiers.
  • Other advantages include no effect on pH, higher solids sludge, low sludge volumes and the formation of dense, rapid settling flocs.
  • Polyamine is not corrosive and handling is relatively simple, it can be stored in most materials except mild steel. LDPE tanks are recommended.Consistent and sensitive dosage control is required as polyamine dosages are typically in the order of 1-10 mg/l and a relatively narrow optimum dosage is exhibited. This necessitates adequate laboratory facilities for determination and monitoring.
  • Most polyamines can be metered neat through positive displacement diaphragm pumps with a suitable viscosity rating followed by in-line dilution with clean water to a suitable concentration for rapid dispersion. Dilution to a suitable concentration as a stock solution followed by metering can be used but care is required to ensure an accurate solution strength.
