Maintenance of Spray Humidifiers

摘要

Recycled water can become a breeding medium for micro-organisms particularly if there is nutrient such as organic dust present. If such micro-organisms and/or their metabolytes are injected into the atmosphere in quantity by a spray humidifier then the room occupants are liable to develop flu-like symptoms now known as 'humidifier fever'. The symptoms are worst on re-exposure after an interval and lead to the expression 'Monday sickness'. Any industrial process involving both humidification and organic dust offers a potential breeding ground for the micro-organisms. The most common process combining the two is the stationery and printing industry. Winter humidification is necessary and nutrient in the form of airborne cellulose from the paper is plentiful. Particularly high standards of maintentance, including regular cleaning and prevention of sludge buildup is needed.
