Abstract: “n this study an eco-mill system with new technology was developed to overcome the current palm oil mill issues such as vast Palm Oil Mill Effluent (POME) ponds, large mill area, reliance on water supply, oil quality, oil loss, and energy etc. In eco-mill process two distinct technologies such as megasonic clarification system and ultrasonic horn press system was developed to replace the conventional clarification system and sterilization system. Megasonic clarification process can separate the Crude Palm Oil (CPO) more effectively without any dilution (no additional water required) and within short period of time with lowest temperature (~ 80 °C). This results in high quality oil with minimum oil loss. Ultrasonic horn press system can rupture the oil cells within the palm fruits and also press the oil emulsion out from the fruits within 20 sec with controlled temperature (~ 70 °C). These changes can influence POME treatment process and at the same time reduce the treatment cost signifi”
