Item Assessment of Land Use effects on Tuul River surface water Quantity and Quality(GMIT, 2022) Bolorchimeg Turkhuu; Ariuntuya Tserendor; Byambakhuu IshgaldanThe Tuul river basin is a unique region in that it covers only 3.2% of Mongolian territory, but 48% of Mongolian total population lives in Ulaanbaatar. Also, 66.5% of the Mongolian total GDP was produced within this river basin in 2020. Land-use changes due to the expansion of urbanization can pose a threat to downstream ecosystems of the Tuul river, particularly soil and water quality, leading to an increase in surface runoff and nutrient loads.Item Determination of Deoxygenation Rate Constant for BOD Reaction in Mongolia(GMIT, 2019) Sanchirgarav Batzorig; Ariuntuya Tserendor; Daniel KartheThe objective of this study was to estimate the deoxygenation rate constant and the ultimate BOD of WWTP effluent in Mongolia. The deoxygenation rate was determined and tested in April, 2019. The Deoxygenation rate was 0.31 /day which is a bit higher than values from other countries. The ultimate BOD was in the range of 92- 115 mg /L. Biological oxygen demand values did not meet the limits recommended by the Mongolian National standard throughout entire study period.Item DETERMINATION OF DEOXYGENATION RATE OF SELBE RIVER AND ITS PURIFICATION STUDY(GMIT, 2022) Usukhbayar Puntsagsuren; Ariuntuya Tserendor; Gerelt-Od DashdondogMongolian people have a proverb “Water is a wish granting jewel” or “Ус бол чандмань эрдэнэ”, which specifies that Mongolians have been living near to the water sources by cherishing, protecting and worshiping water for the generations.
