Abstract:
Urine and flush water is known as yellow water in general. Releasing of untreated urine to the
environment causes bad odor, aquatic and terrestrial pollution also. The main focus of this research is to
investigate the usage of sand and red brick powder to remove environmental pollutants in yellow water.
Filtration column used for the study was packed by using sand or brick particles in the range of 0.270-
0.355 mm diameter. Continuous flow filtration through column of sand or brick powder was investigated
for removal of total nitrogen, color, conductivity and COD caused by urine. Whilst brick powder
demonstrates good filtration efficiency, sand is found to be inefficient for the intention. Initial efficiencies
demonstrated by brick powder for removal of total nitrogen, color, conductivity and COD were 93%, 92%,
55%, 65% respectively and decreased upon continuous filtration except for total nitrogen. During the
study, total nitrogen removal efficiency remained constant.
