Physical-Chemical characteristics of the Substances Before and After the discharge of factories of the detergents that can cause increase of the degree of the eutrophication of surface waters in the city of Prizren

Industrial discharge waters, especially those of producers of detergents are one of the main polluters of surface waters in Prizren. The greatest polluters are: vehicle laundry and laundry of mega clothes, as well as factories producing liquid detergents, as well as powder ones. Concentration of active substances and perborate polyphosphate detergents also increase the wastewater from households. Therefore, we can say that the washing detergents, cleaning, are not safe for the environment, all of those are in varying degrees dangerous pollutants. Their presence represents the most acute problem of water supply in the city of Prizren. In this paper are treated physico-chemical indicators of pollution that may be caused by emissions from factories producing washing substances in the region of Prizren, Kosovo. And especially, will be treated contaminants from the manufacturing industry to washing agents, whose production due to massive use causes the polluting of current waters. This has happened because they have not paid attention to the chemical and physical- chemical features of phosphates and other compounds that affect eutrophication of Lumbardhi River. The problem of eutrophication also represents a form of disruption of the ecological balance of nature and consist with increasing phosphorus compounds in waters, where it causes the rapid development of the planktons and algae, causing damage to water quality. The Microbiologic problem of dissolution of tensids even at low concentrations causes creating dense and stable foam in waters surface, which prevents digestion of oxygen from the air into the water and thus the question of the survival of flora and fauna in those waters of the river Lumbardhi, as well as its use for drinks. This problem is caused by the wide use of detergents that contained tensids with branched range of hydrocarbons, which as the main representative is dodecyl benzene - sulfonate of tetramer type

Dynamics of improvement of some physico-chemical parameters in Lumbardhi River of Prizren from urban water discharges for the year 2018 compared to the year 2017

The rapid growth of our city Prizren and urban problems, especially those of sewage, resulted in the pollution of the Lumbardhi River, since urban wastewater was not treated in advance until the year 2017, therefore in 2018 the collectors were built aimed at mitigating river pollution. Therefore, the purpose of the paper is to compare and evaluate some basic physico - chemical pollution indicators without treatment of urban waste water in 2017 with those treated with collectors of the year 2018. The physico - chemical parameters to be treated are: Content of Dissolved Solid Substances in Water (DSS) that limits the use of water for irrigation and industrial purposes, BOD5 level that is not suitable for the life of living things that require oxygen, Chemical Oxygen Demand (COD) that is a parameter which is used to measure the content of organic substances in urban and industrial water remains, and the total organic carbon (TOC). The monitoring points of the physical and chemical analyzes in our study in Lumbardhi are: Entrance to the city - Marashi (L1), City Center - Municipal Assembly (L2) and City Suburb - Vlashnje (L3)

Evaluation of physical - chemical contaminants in Lumbardhi River in Prizren for the period May - June 2017

This paper covers the monitoring of water pollution in the river basin from the source to the White Drin flow monitoring the river flow both in the rural and urban areas of water quality. The biggest problem in environmental protection is the quality of surface water. The results from the analysis of the study will serve to know the pollution from these physical-chemical parameters and at the same time to manage the eco-status in order to prevent negative trends and create a desirable balancing of so important the ecosystem as it is the system consist of Lumbardhi River, with biodiversity still maintained. The purpose of the work is to know the pollution of the Lumbardhi River during the period May-June 2017 as we think during that period of time there is a larger water flow due to the atmospheric rainfall and melting of the snowfall from the mountains because the river source is from an altitude of over 2500 meters and has an extension of 37 km to its discharge into the next river. On the other hand, based on the ecological condition and the physicochemical characteristics of the Lumbardhi River during time intervals, will serve as a starting point for integrating them into the management plans and if necessary for the programs, measures and environmental protection activities that should be undertaken to prevent our river pollution as we are dealing with a river that runs through the middle of our city and if clean, it would increase the beauty of our city with its landscape. So, the samples for analysis have been taken in four sample locations with different distances that are marked with L1, L2, L3, L4 and the same ones will be presented in our fig. The analyses are done at the hydro meteorological institute of Kosovo Pristina
