Ecological pollution assessment of workplace air at the production of lubricating oils, bitumen and additives

The precipitation process of the suspended particles descending in brightening agents of shop water preparation by using of various coagulants and flocculents is investigated. The influence of polyelectrolyte’s (polystyrenesulphoacid and polybenzylthrimethylammonium chloride) on the quality of water purification is studied. The efficiency of polyelectrolyte’s as coagulants was estimated. The optimum concentration of polyelectrolyte’s in water was determined to be equal to 30 mg/l.
