Ill. Pumps are near the top of the list of essential equipment in pollution control systems. Wastewater is generally purified by pumping it through a filtration or sedimentation system. The treatment chemicals are also introduced in liquid form by pumps. Even air pollution control systems employ pumps.
Scrubbers operate with recirculating water.
So pumps are used to move the clarified water to the scrubbers and are also used in the various steps to separate the captured pollutants from the scrubber wastewater. This is the forecast in Pumps World Market 1999-2004 authored by the McIlvaine Company and available through the Hydraulic Institute. The top three pump companies will achieve a 1999 combined market share of more than 19 percent while the Top 25 companies will capture 50 percent of the market. The Top 800 companies will have a 90 percent market share. Over 500 niche players will continue to maintain niche market leadership in regions or in special applications.
