Researchers Develop New Machine for Road Cleaning with Sewage Water
Researchers at the CSIR-Central Mechanical Engineering Research Institute (CMERI), Durgapur, have developed a machine that could be useful in maintaining good cleanliness and hygienic standards of Indian roads/streets. This machine sucks out the wastewater from drain/manhole using slurry pump. The drain water passes through multiple chambers and screened by different mesh size sieves, before it is finally treated with chemical disinfectant. The treated water is stored in a separate chamber that is used in jetting operation. The water intake capacity of the machine from one manhole is more than 1000 litres. The machine can utilize the water to clean the road up to next available manhole within 50-70 meters.
