ASSESSMENT OF INDUSTRIAL WASTEWATER POLLUTION IN DEVELOPING COUNTRIES – CURRENT POLLUTION LEVEL IN RWANDA.

In both developed and developing countries, wastewater treatment has been a serious matter on small and large scale. Created industries, enterprises and factories manufacturingfinal products from raw materials use fresh water in their processeswhich result in wastewater heavily loaded with various pollutants. Pollution level depends on the type of factory or industry. Although some industries /factories date from nineties (90s), Industrial sector is quite new in Rwanda.Industrial reforms started early 2000 with Rwanda vision 2020 launch where by 2020, industrial and service sector will contribute about 42 % of country’s GDP. BOD, COD, Nitrates and phosphates were measured, Analyzed and show that Horizon Sopirwa, AMEKI color, UTEXRWA and Nyanza dairy have the highest concentration in Nitrate, Phosphate, BOD and COD respectively. Results found that at least each factory/industry has surpassed Rwanda Bureau of Standards’ effluent limits given on the appendix. Pretreatment and further analyses have been recommended in order to deepen Rwanda’s water pollution understandings and taking environmental pollution prevention measures.
