Abstract

Water plays an important role in everyday life. Therefore, the subject of the analysis was the water along the upstream of the fifth channel MM1, MM2, MM3, which is located in the city of Bitola and the Crna River - MM4 where the channel inflows into the river . The survey was conducted in May and November. The following chemical parameters were made: the content of ammonia and nitrites in the water was determined spectrophotometric, pH value with a pedometer, determination of nitrates with UV pastel, the consumption of potassium permanganate was determined by boiling in acidic environment and titration according to Kubel-Tiemann. From the obtained results, it can be concluded that the largest ammonia load (2,2mg / L) is in the measuring point MM3, while the same values where the channel inflows in Crna Reka in MM4 are reduced. One of the recommendations is the implementation of treatment for wastewater treatment before being discharged into the rivers.
