<br />RELATED FILTER DESIGN AND <br />RENOVATION PROJECTS IN TEXAS <br /> <br />evolved, filtration remains the heart of the <br />water treatment process, and its design <br />remains a core part of our water treatment <br />design practice. Freese and Nichols' <br />experience includes a wide range of sizes and <br />configurations, various media combinations <br />, <br />control strategies and backwash <br />arrangements. The table below lists some of <br />the more recent filter projects completed or in <br />progress by Freese and Nichols and selected <br />projects are described in greater detail. <br /> <br />Freese and Nichols was founded over a <br />century ago when the City of Fort Worth <br />found it necessary to filter its public water <br />supply and hired the firm's founder, John B. <br />Hawley, to design and supervise construction <br />of its water filtration plant. Since then, the firm <br />has designed numerous filters and <br />rehabilitated or upgraded many others.
