In this research, it is aimed to study the effects of ozone when fed into four-stroke internal combustion gasoline and diesel engines on the break power, break specific fuel consumption and on the specific emission parameters. Two main parameters are specified to examine the effects of ozone gas on characteristic features of the chosen engines. Sets of experiments were prepared for each and every speed; one without using any ozone and five by using different feed mass flow rate of ozone. By using these sets of experiments , the time of combustion of the fuel per unit volume For a better evaluation of the experimental results, the experiment was repeated three times at each point and the all experiments required for the analysis method of Desing-Expert 8. After the engine warmed up at first it is experimented without feeding any ozone to the engine inlet while dry air was passing through ozone production system.

The setteability characteristics of sludge was also found better than that of the control system in terms of SVI. Besides, it was revealed that the OSA process especially based on sludge decay and energy uncoupling metabolism can be used as another simple devir saati neden çalışmaz method for sludge reduction. The sludge characteristics of activated sludge were changed even slightly for some paramaters after the application of sludge minimization techniques.

The reduction of dry mass of sludge leads to the reduction of solid content and volume and this strategy should be fovoured, beause it allows the immediate reduction of sludge dry mass during its production in the biological treatment stage. Ozone run had lower dewaterability characteristics with higher CST values. The effectiveness of ozonation integrated in activated sludge process and oxic-settling anaerobic OSA process were investigated on sludge reduction, especially. However; if the ozone was fed while the gasoline engine was running at full load, it was observed that it caused knocks at multiple points of the engine, therefore did not have a positive effect on engine parameters. After the determination of optimum operational conditions of activated sludge process, two systems were operated in parallel under these optimum conditions during 45 days until the steady state conditions and the effluent quality and sludge properties of the systems were monitored. In the first stage of the study, Box-Behnken Statistical Design Program was used in order to determine the optimum operational conditions. The higher doses improved disintegration degree, slightly. The cause of different effects of ozone on gasoline engines and diesel engines was associated with the diesel engine operating principles. Then the experiments were conducted by gradually changing the amount of ozone fed to the system. Contact Us Send Feedback. Size: 1. The filterability of ozonated sludge was lower than control run in terms of SRF. After the ozone dose optimization study, the effectiveness of partial ozonation of return activated sludge was investigated for the minimization of excess sludge production using ozonation coupled with activated sludge process in two stages. OSA and control system were operated during 45 days.

The current approach to sludge minimization is the reduction of volume of wet sludge and the reduction of dry mass of sludge. All of the techniques for sludge reduction described in this thesis suitable for implementation during the wastewater treatment plants, not after the sludge production, often by retrofitting the specific additional equipment. This research shows that especially in gasoline engines if the correct scaling of application of ozone can be done and high energy-efficient ozone generators can be adapted to the application is possible to attain to the aimed benefits. Sludge settling properties was improved in ozone run in terms of SVI. DSpace Repository Minimization of excess sludge production Login. Fuel consumption is measured by using a fuel gauge recording the time and the depleted amount of fuel per unit volume. It was revealed that the OSA system enhanced the filterability of sludge. Size: 1. For a better evaluation of the experimental results, the experiment was repeated three times at each point and the all experiments required for the analysis method of Desing-Expert 8. The aim of the first batch experiment was to investigate the relationship among sludge anaerobic reaction time, sludge lysis and sludge yield. The cause of different effects of ozone on gasoline engines and diesel engines was associated with the diesel engine operating principles.
