Does Contec use polyaluminium chloride in potable water treatment?

Polyaluminium Chloride Argentina, where PAC is not used at all as flocculants in potable water treatment, Contec has built two PAC plants and in 5 years almost all the drinking water is treated with PAC. Poly Aluminium Chloride process has been fine tuned by Contec during these years.

Is polyaluminium chloride better than polyelectrolyte – alum-based coagulation?

At the Barekese Water Treatment Plant in Ghana, an alternative, the polyelectrolyte – polyaluminium chloride (PAC) is also used in coagulation but limited information is available on the operating conditions required to achieve better performance than alum-based coagulation.

What is polyaluminum chloride (PAC)?

Polyaluminum chloride (PAC) is an important flocculant in potable water and wastewater treatment. Al13 or Alb is regarded as the most efficient species of PAC. A low base addition rate, small base drop sizes, and sufficient mixing usually favor the formation of PAC with higher Alb contents.

What is PAC used for?

PAC is widely used in the treatment of drinking water because of its high antibacterial effects. Polyaluminium Chloride is used in the process of flocculation for wastewater treatment. Polyaluminium Chloride is used as a coagulant in paper and pulp industries.

Does polyelectrolyte –polyaluminium chloride Formance improve coagulation performance in water treatment?

At the Barekese Water Treatm ent Plant in Ghana, an alternative, the polyelectrolyte –polyaluminium chloride formance than alum-based coagulation. The aim of this study was to determine the optimal coagulant dose, mixing speed and operating pH for enhanced performance in water treatment.

What is Pac based water treatment?

PAC is the polymer adopted by the Ghana Water Company Limited (GWCL) and the Barekese Water Treatment Plant management in Ghana. However, limited information is available on the optimal dosage and operating conditions for PAC-based water treatment.
