Treatment of waste water or recycling of water for reusing of different beneficial purposes like drinking, irrigation, toilet flushing, and industrial processes saves water resources. It also offers economic savings. The main purpose of installing an air conditioning unit is to get the cooling effect. Water is produced from air conditioners, with no cost as a by-product which is usually unused in Bangladesh. This thesis aims to determine the important properties of condensed water of an air conditioning unit. This study also illustrates the uses of this unused valuable water. Water analysis is based on chemical tests as total hardness, turbidity, dissolved solids, alkalinity, electrical conductivity, copper, lead, iron, manganese, and chloride content, dissolved oxygen, pH, chemical oxygen demand, total suspended solids, biological oxygen demand, and corrosivity. Meanwhile, sample quantity measurements were performed. Attained water has to some extent basic pH, close to neutral range. Total dissolved solids, copper, lead, total hardness, electrical conductivity, and alkalinity of condensed water are in very short ranges. In average, every 2-ton air conditioner formed 25 liters of water each day. This research shows the feasibility study of using this condensed water in the battery, automobile radiator, boiler, toilet flushing and washing clothes.
