Physicochemical Properties of Sugar Industry and Molasses Based Distillery Effluent and its Effect on Water Quality of River Musamya in Uganda

Physicochemical Properties of Sugar Industry and Molasses Based Distillery Effluent and its Effect on Water Quality of River Musamya in Uganda



Yonah K. Turinayo



Despite the economic and ecological importance in
terms of supply of water for industrial and domestic use, irrigation and
support of aquatic life, River Musamya receives over 1000m3 of
wastewater per day from the nearby sugar industry. However, there is
scarcity of information regarding water quality of the River after
wastewater discharge. This study determined the physico-chemical
properties of a sugar industry and molasses based distillery effluent
and assessed its effect on water quality of River Musamya. The analysis
was conducted between February and April 2010, using standard methods
for the examination of water and wastewater. Results showed that
pollutant concentrations (4.3 pH, 9104mg TDS/l, 48mg TN/l, 16 mg TP/l,
2256mg BOD/l, 8064mg COD/l) of wastewater (2,523±728 m3/day) were above
permissible limits (6.0 – 8.0 pH, 1200mg TDS/l, 10mg TN/l, 10mg TP/l,
50mg BOD/l, 100mg COD/l) by NEMA. This significantly (P < 0.05)
altered the water quality downstream the River after discharge. The pH,
TDS, T-Fe, Na+, Ca2+, TN, TP, Turbidity, BOD, COD of the upstream and
downstream river after wastewater discharge varied from 7.1 to 5.6, 88
to 1007mg/l, 3.2 to 10.5mg/l, 5.5 to 8.0mg/l, 8.5 to 25mg/l, 1.4 to
6.8mg/l, 0.8 to 2.7mg/l, 49 to 616NTU, 3.8 to 184mg/l, 13 to 675mg/l,
respectively, and the difference was significant (P < 0.05).
Therefore, environmental pollution mitigation measures should be put in
place to mitigate deterioration of River Musamya’s water quality. The
sugar industry and distillery should employ technologies that reduce the
quantity of wastewater and also install a treatment system that impacts
less on the environment.

The Ecological Impacts of Light Pollution at Night-time a Mechanistic Appraisal

The Ecological Impacts of Light Pollution at Night-time a Mechanistic Appraisal Abdullahi MG, Roslan U, Kamarudin M. K. A. Artificial light at night and its negative consequences are of great interest in the fields of Ecology, Human Geography Astronomy, and Human Health. Most of the studies to date concentrated on the influences of light pollution has on our ability to view the night sky, on biodiversity, and ecosystems. Though, in recent years, with the use of new technologies sensors, which provide accurate information for determining of night lights at the area, most consideration were given for estimating artificial light at night within the urban areas. In this study, urban night lights within the cities of Nigeria was evaluated by monitoring data from the ground measurements using Sky Quality Meter (SQM-LU-DL) devices. Besides, the SQM was used at the zenith (upward direction) for maximum evaluating of artificial light at the sites. Differences in night sky bri...

Studying the tendency of citizens to participate in the protection and development of land scape in Tehran

Studying the tendency of citizens to participate in the protection and development of land scape in Tehran Shadi Maleki, Abbas Mafi, Seyedeh Mahsa Hosseini Today, as an essential part and parcel of urban landscape that they play a major role in metabolism and create a lack of serious damage to urban life. This study performed to investigate the willingness of citizens to participate in activities to protect and develop landscapeof Tehran district 4. The research was descriptive and correlation method that is used for collecting information. The statistical population consisted of district 4 of Tehran. The sample size was determined 230 by using Cochrane method. A questionnaire was used to collect data. According to the research, 63.04 percent of citizens showed participation in a high level. Among the variables investigated how citizen participation in conservation and development of landscape, effective strategies to motivate citizens to participate,the reasons for la...

Land Use Land Cover Change Detection by Using Remote Sensing Data in Akaki River Basin

Land Use Land Cover Change Detection by Using Remote Sensing Data in Akaki River Basin Adimasu Woldesenbet Worako   Land use land cover change (LULCC) is the result of the long time process of natural and anthropogenic activities that has been practiced on the land. GIS and remote sensing are the best tools that support to generate the relevant land use/cover change in the basin. This study was conducted in the Akaki River basin to detect land use land cover changes within the 30 years period (1985-2015) by using landsat imagery data acquired from the GCF. Supervised maximum likelihood algorithm classification were deployed to classify land use/cover into four prominent land use groups and data’s were processed by using ERDAS imagine 2014 and ArcGIS10.1 software. In the basin dominant LULC was agricultural land use which accounts around 56.28% and the second largest is built-up area by 31.51% and the rest, forest(11.9%) and water body(0.31%) coverage were takes t...
