Valencia-based Istobal is currently saving over 6,000 litres of water every hour in bus washing facilities.
The Spanish firm says it is saving around 6,380 litres of water every hour in exterior wash services for buses thanks to a new recycling system that helps to improve the quality and safety of recycled water, as well as increasing the amount of water saved when cleaning large vehicles of all kinds.
The new Physical Recycler Plus is compatible with all the automated equipment Istobal provides for cleaning the exterior of vehicles in any fleet. With it, the company is achieving average hourly savings of 5,670 litres in wash services for waste collection trucks, over 6,300 litres for buses, over 3,700 litres for trailers, and over 600 litres for trains.
Istobal has also called for water to be used responsibly in wash services for industrial and passenger vehicles.
The firm tells us the Physical Recycler Plus achieves a water recycling rate of up to 88.8 per cent depending on the wash machine and its optional features. It also reduces the level of contamination in the waste water, elimates odours, and prevents the risk of legionella in the wash facility. Furthermore, it improves the quality and safety of the recycled water by decreasing the level of turbidity and the amount of surfactants in the water.
Commercial vehicles generate higher levels of contamination in the waste water from the wash process. Thanks to the addition of chemical and microbiological products, and with its higher ventilation flow, the Physical Recycler Plus allows more heavily contaminated waste water to be treated. It also eliminates unwanted substances – such as metals from overhead line equipment on trains that solidify with the coagulating agent, or organic matter deposited when cleaning waste collection trucks – by injecting microorganisms.
Another benefit of the recycling system is that it allows car wash services to be provided in facilities that face water restrictions following prolonged periods of drought.
