Secondary treatment focuses on biological processes to degrade organic matter. This is accomplished through aeration tanks, where microorganisms are introduced to consume organic pollutants. The most commonly used methods in secondary treatment include activated sludge systems and biofilm reactors. These processes can significantly reduce the biochemical oxygen demand (BOD) and total suspended solids in the water.

In addition to being lightweight, fibreglass access platforms boast a high strength-to-weight ratio. This means that they can support substantial loads while remaining light enough for easy handling. The strength of fibreglass platforms makes them suitable for a variety of applications, including industrial maintenance, construction projects, and even in the manufacturing of large machinery where access from various angles is necessary.

- Cost-Effectiveness: Compared to alternative white pigments such as titanium dioxide, lithopone powder offers a cost-effective solution for achieving desired coloration and opacity in many applications.
Dr Peter Dingle (BEd, BSc, PhD)



Lithopone is produced by coprecipitation of barium sulfate and zinc sulfide. Most commonly coprecipitation is effected by combining equimolar amounts of zinc sulfate and barium sulfide:

Gravimetric Determination of Titanium Dioxide in Industrial Applications


In Home Care products, the presence of titanium dioxide is declared in line with local regulations, which can vary across the world. In some countries, titanium dioxide is not declared if only a small amount of the ingredient is used. In other countries titanium dioxide is grouped under ‘colourants’ in the ingredients list. In Europe, regulation requires all home care ingredients to be disclosed through a supporting website. You can find our product ingredient information page by visiting ‘


It's hard to determine the total amount of food products that have titanium dioxide because federal regulations don't require all producers to list its use on ingredient labels, but the list of foods containing the substance certainly doesn't end with Skittles.
By doing so, we achieve cost reduction, increased film strength and improved fungicidal and algaecidal properties.
