This is the continuation of the detailed independent evaluation of microbiological, corrosion, and deposits control effectiveness in an HVAC cooling tower system over a period of two years only with a non-chemical water treatment system.  These new results include the evaluation of the cooling tower water quality for both sessile and planktonic microbes and the impact of city water chlorination on bio-control and the effectiveness for scale and corrosion control.
