    Observation of Quality and Quantity of AC Water
    (Daffodil International University, 22-09-21) Hasan, Mehidy; Das, Roki Kumar; Islam, Md. Saidul; Saha, Hridoy
    Today, a large portion of the world is experiencing water scarcity. The global demand for freshwater is increasing every day. The demand of fresh water is increasing day by day in big cities especially for Dhaka city where the groundwater table depletion rate is about 2 m to 3 m per year. As a result, other sources are being investigated in order to reduce demand. Water from air conditioners (AC) could be used. The water from air conditioner is usually wasted. The water from the air conditioner is good water and "clean," in general. We are first collecting water from air conditioning (morning, noon, night). Then we tested the water before and after boiling. On the acquired sample, various water quality parameter testing were performed. The average concentrations of before boil value pH 7.6, Iron 0, Conductivity 0,Turbidity 0.67, and DO 3.51, BOD 10, COD 36, and after boil value pH 7.73, Iron 0, Conductivity 0,Turbidity 0.80, and DO 2.66, BOD 8, COD 32, in condensate water from air conditioners were determined in this study. We compared the Air Conditioning water quality with WHO’s drinking water standard. Since they don't include any salts or residual solids. We can get extremely cheap clean drinking water with the right filter equipment. The goal of this research is to learn more about how condensate water from air conditioning systems can be reused. A sample of AC water was taken and its volume was calculated over time. Then we get the test value of parameters pH is acceptable but BOD, COD, Iron, Conductivity, Turbidity, and DO are not in acceptable limit.
