Mode of Operations

The screening basket stands under the sewage inlet pipe and filters the sewage. In this position the top cover is closed. Upon receiving a “new cycle” command from the device’s timer, the basket rises up and cover opens automatically. The basket stops at the ejaculation point and the mop removes the rubbish into the dumpster. The screening basket waits for a few seconds at the top to ensure that all the sewage falls into the dumpster. Next the basket moves back down and stops at the waiting point and the lid closes back automatically. The mode of operation can be simply controlled and determined in accordance to the amount of wastewater and type of sewage.
