The passengers travelling in Indian Railways will soon be able to have access to cleaner toilets and stations, MoS Railways Manoj Sinha told Rajya Sabha.
Under the ‘ Swachh Rail Swachh Bharat Mission’, Railway Ministry is focusing on ensuring clean and hygienic toilets, maintenance of cleanliness at stations, trains etc, Sinha said and added, that the initiative will also include tree plantation, removal of encroachments, improving drainage, public awareness campaign and periodic monitoring of the mission.
He said that detailed instructions regarding waste management have been given to Zonal Railways for proper garbage disposal. Railway services at stations and in trains will have waste bins of three colors, Green (for Bio-degradable waste), White (for recyclable waste) and Black (all other waste i.e. other than bio-degradable waste and recyclable waste) of sufficient size to ensure all collections.
The minister also informed that the garbage is disposed by Municipal Authorities through incineration, dumping in identified landfill sites and composing pit etc.
Airplane toilets are loud. For kids, they could be downright terrifying. Now, a team of US researchers has invented a vacuum-assisted toilet that is about half as loud as the regular airplane commode.
“People have told us they don’t want their kids to be scared to use the bathroom on a flight,” said lead researcher Kent Gee, Professor at the Brigham Young University. “We’ve used good physics to solve the problem.”
It’s been a really hard problem to solve because getting airplane toilets to flush with very little water requires a partial vacuum, which at 38,000 feet, pulls air at nearly half the speed of sound.
According to the research, conducted in a lab, an air-water mix in vacuum-assisted toilets travels more than 300 miles per hour.
When things move at that speed, any disturbance at all to the flow — like the bend of a pipe or a valve — generates significant noise.
Now that airplanes come with much quieter interiors, toilet flushes reverberate more throughout the cabin.
However, tests of the new contraption show aeroacoustically-generated noise declined 16 decibels during the flush valve opening and about 5-10 decibels when the valve is fully opened, the researchers reported in the Proceedings of Meetings on Acoustics journal.
To solve the problem, the team focused on three valve conditions during the flush cycle: the initial noise level peak associated with the flush valve opening, an intermediate noise level plateau associated with the valve being fully opened and the final noise level peak associated with the flush valve closing.
