12-08: An Update on ASHRAE Standard 188P: Prevention of Legionellosis Natural Draft Towers

12-08: An Update on ASHRAE Standard 188P: Prevention of Legionellosis Natural Draft TowersThe American Society of Heating, Refrigerating and Air conditioning Engineers (ASHRAE) has developed a proposed Standard Practice that specifies what is required to prevent legionellosis associated with building water systems. The proposed Standard Practice was approved in July 2010 for public review publication. The first public review was completed in November 2010; there were many supportive comments posted and also many excellent suggestions to

non-hazardous environmental characteristics

With wider use of highly efficient film and increasing interest in water conservation many cooling towers are experiencing plugging associated with the concentration of suspended solids from the make-up water

Microorganisms that contaminate a variety of cooling water systems produce Biofilms

A heat recovery system is utilized between cooling tower discharge and intake to pre-cool warm and dry entering air to reduce its wet bulb temperature

ozone replaced chlorine in a crossfire induced draft-cooling tower at a Henkel Corporation

This paper examines the use of flow cytometry in conjunction with fluorescent nucleic acid and bacteria strains to rapidly enumerate live and dead bacteria in industrial cooling water samples

and chemical attack

equipment manufacturers have grasped for a concrete method to obtain such a certification

It is a non-invasive method based on optical interference beam passed through the transparent particles and the beam reflected by such particles

The precipitation is always proportional to the water's alkalinity

the availability during winter periods and the ageing of the heat exchange equipment

The paper describes the importance of applying professional project management knowledge to help identify and reduce the risks inherent in all complex projects
