Our experts in water treatment technologies are involved in a variety of disciplines, including water chemistry testing and assessment, process (chemical) design engineering, research and development, quality assurance, treatment plant operations and reporting, mechanical design engineering, and controls and instrumentation. Their knowledge, combined with our experienced systems engineers, ensures that each of our water treatment solutions meet the exacting demands of each client application.
For complex challenges, such as treating water from coal combustion residual (CCR) ash ponds, our chemists conduct pilot studies and bench tests to determine the precise mix of contaminants in the source water. Our experts then design a system that targets that unique contaminant profile. The result is a highly engineered water treatment system that operates effectively and efficiently.
GWTT can engineer a system to treat virtually any contaminant profile at any flow rate. See below for a sampling of our application-specific treatment experience.
