Quality Assessment of Condensate Water Generating From Air Conditioning Units

Abstract: The growing demand for water resources in urban areas like Bangladesh is a pressing concern due to population growth. Air conditioning condensate water is being considered as a potential solution. A study at the European University of Bangladesh (EUB) examined the quality of AC condensate water from various systems. Results showed that the water generally met quality standards for drinking and household use in Bangladesh, with average parameters like pH (6.8), turbidity (1.08 NTU), total dissolved solid (TDS) (219 mg/L), iron (0 mg/L), alkalinity (41.67 mg/L), arsenic (0 mg/L), COD (3.67 mg/L), BOD (1.33 mg/L), chloride (30.77 mg/L), and more. AC units at EUB (1 ton, 2 tons, 4 tons) produced monthly volumes of 96, 177, and 354 L, highlighting the potential of AC condensate water. This emphasizes the need for local decision-makers to establish guidelines for its effective use in combating urban water scarcity.
