Improving the Environmental Performance of Interior Spaces through Greywater Treatment

Abstract

The experiment also contributed to the introduction of a new environmental dimension, which is the capacity to utilize the high heat capacity of the water to enhance the environmental performance of internal space through the development of a novel method for storing treated water and the design of tanks in a manner akin to the Trombe wall, which eliminates unused space in conventional tanks and functions to heat and cool the space in the winter. Two hours were spent on this procedure. The final stage of treatment involved floating and disinfection with a motorized scraper to remove the built-up coating of oil, akum, and detergent components. The flotation procedure took two hours, and then the chlorine disinfection phase required one hour of contact time. The elimination rates varied considerably between the various stages of therapy. Each level of treatment had a significant impact on physiochemical metrics, microbiological parameters, or both. Following the disinfection procedure, the clearance percentages for COD, BOD5, TSS, Turbidity, Total Coliform, and E. coli were, respectively, 89.25%, 91.32%, 90.98%, 94.72%, 99.9%, and 99.75%. Following disinfection, greywater was compared to Egyptian regulations for reusing treated wastewater in agriculture. The final measured parameters were below class (B), allowing the treated greywater to be used for roses, fiber crops, and nursery plants. Additionally, it may be used to flush showers and toilets. By using the high heat capacity of the water, where the temperature rises and falls gradually, the research added a new dimension to the treatment of grey water and created a storage method that improves the environmental performance for internal spaces. This helps to moderate the temperature inside the building.
