Ozonation is a promising treatment step for water reuse. Compared to the “gold standard” with reverse osmosis and advanced oxidation, ozone requires less energy and does not result in a waste brine. This makes ozone more cost-effective. However, the formation of nitrosamines may be a significant barrier to the use of ozonation in water reuse applications, particularly for potable reuse.

Project Background
• Many rural areas on the planet do not have easy access to clean water!
• Water distillation basins are capable of distilling water by using incident solar radiation to evaporate polluted water.
• Current thermodynamic models used to predict behavior require instantaneous data; requires the use of expensive equipment.
• Distillation basins are dependent on multiple meteorological variables: insolation, temperature, wind speed, cloud cover.
• Non‐linear behavior is difficult to predict for long term operations.

Throughout the history of the construction industry, many fatalities and injuries have occurred in construction sites. One of the major causes of accidents is unsafe site conditions: basically, this is due to inadequate supervision. To improve upon the traditional supervision approach, this study proposes a 'Framework Development for Construction Safety Visualization' approach. In addition to this, a computer vision Edge Detection Algorithm was developed and tested to convert construction site still images into edges of the objects in the images. The framework development of this study uses computer vision, robot vision, image compression, pattern recognition, internet transmission, network communication, and …

Endocrine-disrupting compounds (EDCs), such as estrogen, are known to be present in the aquatic environment at concentrations that affect fish and other wildlife. For example, juvenile male fish exposed to estrogen will synthesize vitellogenin, which is a female-specific protein. Estrogen exposure is also linked to sex reversal, intersexuality, and inhibition of gonadal growth (Jobling et al., 1996).
Wastewater treatment plants are major contributors of EDCs into the environment. EDCs end up in wastewater as a result of natural excretion from the body or being washed off the skin. WWTPs are not designed to remove these substances. As a result, EDCs …
