Evaluation of Non-Organic Solids Removal in Wastewater Treatment of Pulp Factories with Ozonation

In this research, evaluation, assessment and comparison of Non-Organic solids removal with and without ozonation in treatment of a pulp factory`s wastewater with and without sediments were accomplished. Wastewater of pulp factories which are by-products of cellulose causes a hazardous water vapor that is dangerous because of containing different combinations of chlorophenol. This is known as a pollutant factor in the environment which is even not possible to be solved by treating wastewater in traditional ways. The most hazardous part of these substances is monomers of chlorophenolic combinations which in biological reactors in a liquid phase could be absorbed much easier and with a high velocity. Once the treatment was done, the non-organic solved and suspended solids removal through an ozonation treatment system compared to the same parameters in the without ozonation treatment method. The evaluation proved that the cyclic ozonation-biotreatment system had more effective results in removing the non-organic solids with and without sediments. Experiments showed that the ozone value never reached the ozone value in the new comer wastewater to the system when wastewater of system was consumed again. It means that if new wastewater is entered, the ozone value is more than the previous one in the system.
