The Two - Phase distillation tube is used to purify the grey water which is considered to be waste sewage that drained out from all kind of houses and industries. The waste sewage water is usually let directly to the local sewage drain which is pipelined to rivers and obviously the river water is polluted and even marine life also affected in a large scale. When such polluted river water is used to grow crops that results in unhealthy crops and harmful food products which certainly causes injurious to human health. This problem can be addressed by a Two - Phase distillation tube methodology. The distillation tube will filter all the sewage water before it reaches the local drain. This water can be purified and made reusable again or it can be let to the local drains to river so that river pollution can be avoided. The purification is possible with the help of mechanical filters such as Nanofiltration filter and Reverse Osmosis filtration (RO) filter. Since bacteria and micro-organisms are filtered, these filters blocks them passing through it for which a customized design is used with these filters that performs efficient purification. This entire system also includes a mechanism to separate waste solid particles, the extracted solid waste is collected and that can be converted into manure and used for agriculture. The main problem focused is water purification and river pollution control which would be very efficient and smart method to recycle waste water and reuse by way of two phase distillation technique which can also referred to be two stage purification. The complete system can be made Internet of Things (IoT) based and the physical condition or status of the system can be monitored online as variety of sensors are associated so that maintenance notification alerts can be pushed to the subscribed customers.
