Utilization of natural polymeric organic compounds for assisting coagulation process with aluminium sulfate

Abstrakty
Continuously growing social awwareness in the area of health protection issues, results in a constant increase of the requirements for e.g. drinkig water quality. Therefore, the water treatment processes has to become and more efficient; for surface waters the process intensification focuses mostly on the coagulation and filtration processes. One of the proposed solutions, very beneficial for water treatment efficiency, is application of the substances enhancing the coagulation process (high-molecular organic polymers). Their role is particularly noticeable when high fluctuation of water quality is observed as well, as in the periods of low temperatures. Since application of synthetic polymers has met with an opposition, due tho their possible harmful impact to human health, an extensive research has been directed towards using as the flocculants polymers of natural origin. For now, the best solution seems to be application of polysacharides (pectin), which are safe for the human body and are commonlyt used in the food industry. The paper presents the results of the rresearch work, focused on the evaluation of the possible application of pectin substances for enhancement of the surface water coagulation process. During the research, an analysis of the results of both surface and volumetric coagulation with alum sulfate has been performed.
