(2.5 x 02 Nos = 5 lakh gallon = 500000 X 4.5 = 2250000Ltrs ). Location : Main pump house (a) First stage : MECHANIZED DEWATERING: This first stage consists of emptying water from the tank. A submersible pump is used to drain the tank of excess of water. Removal of water and semi sludge with the help of Sludge pump (electrical/hydraulic). |
| 2 | (b) Second stage : SLUDGE REMOVAL: A sophisticated suction process is used to drain the excess sludge out of tank at a safe place away from tank. Removal of mud, sand and solid particles up to 4 inch size with the hydraulic sludge pump. (c) Third stage : HIGH PRESSURE CLEANING: The tank is then cleaned using high pressure jet machine. The rotary jet is used to clean walls and ceilings, whereas plain jet is used to clean the corners of the tank. The rotary jet acts as scrubber and can clean the most stubborn depositions. Cleaning of floor, walls and ceiling with the help of German made high pressure rotary jet pump having pressure range between 80-180 bars. |
| 3 | (d) Fourth stage :MECHANIZED SCAVENGING: Mechanical scavenging using Eco-friendly, Health & Safety disinfecting chemical for removing rest over algae in water storage tank"s wells to insure minimum harmful pathogens.
