Abstract

Indonesia has palm oil harvesting as the most important agriculture crop. Unfortunately, this agricultural activity delivers a large amount of by product, known as palm oil mills effluent (POME). The treatment using membrane bioreactor has successfully removed the heavy organic component of POME but it left water in colour. This paper proposed the use of a single switch resonant converter with parallel load resoant with dielectric barrier discharge ozonizer to remove colour of treated POME. The ozonizer chamber was made from a planar metal dielectric barrier discharge construction. A single switch resonant converter as power supply to the chamber was designed and it is based on resonance principle. This circuit converted a direct current low voltage input into high frequency and sinusoidal voltage output. The high voltage created micro electrical discharges inside chamber to generate ozone from oxygen molecules. At atmospheric pressure and ambient temperature, the ozonizer deliver up to 2300 ppm ozone gas. The ozone gas was injected into the treated POME for several duration of time. The results of experiment showed that the treated POME water has successfully changed in colour from 100 mg/l Pt.Co into 20 mg/l Pt.Co or lower. As the time of treatment is increased then the colour abatement was below 15 mL/l Pt.Co.Keywords—

Abstract

Ozone gas (O3) is widely used in deodorization,decolourization, disinfection, bleaching processes, gas/airtreatment, chemical synthesis and recently in medicalapplications. Due the wide application of ozone then the ozonegenerator or ozonizer is urgently needed. A single switchresonant converter with ferrite transformer is proposed in thiswork. The prototype is constructed by two parts, first is ozonechamber and the second part is power converter with a singleswitch resonant converter and it supplied by photovoltaicsimulator. The converter is successful to convert 12 volt fromphotovoltaic to 1.89 kVpp high frequency voltage to ozonechamber. The ozone gas produce with the proposed system is 450ppm with oxygen as an input gas.
