Development of new wastewater treatment equipment for silicon wastewater

We have succeeded to develop the new wastewater treatment equipment for silicon wastewater drained from the back grinding process or dicing process. It is based on a new method consisting of a water tank and filtering unit. In this equipment, collected wastewater is concentrated in the water tank then filtered at the filtering unit where at the same time silicon sludge floating in the water is constantly removed by a suction pump. It is quite innovating since such treated water is reusable. It also facilitates maintenance of the equipment because of its much simpler structure compared to existing equipment, resulting in less running costs and less power consumption.
