Preventing corrosion on buses by treating wash water

To save expensive low-floor buses from corrosion, the Delhi Transport department is going to install reverse osmosis (RO) plants for washing the new buses with treated water. Delhi Transport Minister Arvinder Singh Lovely said the water used for cleaning the low-floor buses in DTC depots is hard and saline and it causes corrosion. Therefore, the Government has decided to install RO plants at depots. RO plants remove salts and other impurities and improve water quality. To cleaning one bus, approximately 25 gallons of water is needed. At present, the DTC uses re-cycled water for washing its fleet of 3,200 buses.
