The world market for water and wastewater treatment chemicals in the power sector will rise from $3.4 billion in 2006 to $4 billion in 2010, while other industries will account for $19 billion, raising the total market to $23 billion in 2010, according to a report by the McIlvaine Company (

Growth in the power market will be driven primarily by the continued switch from gas to coal as the fuel for new plants. Coal-fired plants are large purchasers of treatment chemicals, whereas gas turbine plants are only modest users. McIlvaine cites the U.S. ethanol industry in particular as a high growth market for treatment chemicals, as ethanol plants are largely coal-driven facilities.

McIlvaine says Asia will also show rapid growth in the sale of treatment chemicals in a number of industries. With millions of people moving from rural areas to cities in Asia, there is a boom in the construction of water and wastewater plants. As a result, McIlvaine predicts Asia will increase treatment chemical purchases for wastewater plants from $1 billion in 2006 to $1.6 billion in 2010.

According to McIlvaine, corrosion inhibitors will continue to be the leading product category with sales approaching $5 billion by 2010. Organic flocculant sales will rise to just under $4 billion in 2010. Other major categories are inorganic flocculants, scale inhibitors, pH adjusters, and oxidizers and biocides. Relatively small segments include activated carbon, chelants, defoamers, and ion exchange resins.
