Established in 1970, Omega Chemicals is a 100% Australian owned and operated company, specialising in the manufacture and distribution of industrial chemicals.

The company’s first manufacturing site was built in Brooklyn, Melbourne producing Aluminium Sulphate (Alum) for the pulp & paper and water & wastewater treatment industries. The Brooklyn plant still operates today and continues to service many of its original customers among a significantly increased client base.


Since inception, the company has expanded throughout the eastern states of Australia, increasing the number of manufacturing sites to five including the completion of its state-of-the-art Chlor-Alkali plant in Laverton which incorporates Omega Chemicals’ Customer Service Centre.


The business has grown to include the manufacture and supply of Ferric Sulphate (Megaclear 12), Polyaluminium Chloride (Megapac 10), Aluminium Chlorohydrate (Megapac 23), Ferric Chloride, Sodium Hypochlorite (MegaCHLOR), Hydrochloric Acid and Liquid Caustic Soda as well as custom blends of these. Today Omega Chemicals has the largest manufacturing capacity for the production of Alum and Aluminium Chlorohydrate in Australia.

Omega Chemicals has gradually diversified its product range and business activities in line with its ongoing objective for company growth and customer requirements. The company is now catering to the needs of the value-added sector, providing a range of formulations, blends and packaging options to meet the specific needs of individual customers.


The expanded range of water & wastewater treatment chemicals ensures a wider choice of quality products for Omega Chemicals customers, many of whom are responsible for providing water fit for public consumption.


Omega Chemicals supplies both the Australian and export markets, servicing customers in many industries including water and wastewater treatment, pulp & paper, tanning, cosmetics, mining and power generation industries.
