Chemical Supply

ABCO stocks a range of chemicals relevant to the water and wastewater treatment industry. This includes acids, bases, antiscalants and flocculants, as well as specific chemicals for control of odour and wastewater parameters.

Polyaluminium Chloride

Polyaluminium chloride is preferred by ABCO for use as a flocculant in wastewater treatment and some water treatment. Flocculation is a chemical process where colloids and other suspended particles aggregate to larger clusters, known as ‘floc’. In wastewater treatment, this process typically occurs in the primary anoxic chamber, and in water treatment it occurs in the sedimentation chamber. The resulting increase in weight of these clusters causes them to sink to the bottom of the chamber, allowing the cleaner liquor to be extracted from the top.

Liquid Chlorine

Liquid chlorine is used as a disinfectant in both wastewater and water treatment processes. It is dosed into the wastewater plant effluent prior to the nominated water disposal solution. This serves to eliminate E. Coli in the water to allowable levels (below 10 CFU/mL). In water treatment, chlorine levels are maintained at 0.4 mg/L to eliminate any harmful bacteria in the water. ABCO sources liquid chlorine (sodium hypochlorite) at a standard concentration of 12.5% for all its treatment requirements.

Hydrochloric Acid

Hydrochloric acid is used as a membrane cleaning solution in the acidic half of the cleaning process for reverse osmosis water treatment plants.

Sodium Hydroxide Powder

Sodium hydroxide powder is mixed to form another membrane cleaning solution for the basic half of the cleaning process for reverse osmosis water treatment plants.


Bio-GOE is an environmentally friendly product that is used in wastewater treatment for odour control and to reduce grease content in the liquor.

Genesys LF

Genesys LF is a broad-spectrum anti-scalant used in the preventative maintenance of reverse osmosis membrane units. The water quality of the supply to a reverse osmosis plant will alter the specific anti-scalant product required. ABCO offers fully comprehensive water sampling and analysis services to select the correct anti-scalant product for your application.

Polymer 4650

Polymer 4650 is a powerful coagulant used in the desludging of wastewater.
