ISTOBAL saves more than 6380 litres of water every hour in bus wash facilities


Introducing a new physical recycling system that improves the quality and safety of recycled water, as well as increasing the amount of water saved in exterior wash services for all kinds of large vehicles.

ISTOBAL saves over 6380 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.

This new water treatment solution is compatible with all the automated equipment ISTOBAL  provides for cleaning the exterior of vehicles in any fleet. With it, the Spanish multinational company is achieving average hourly savings of 5670 litres in wash services for waste collection trucks, over 6300 litres for buses, over 3700 litres for trailers, and over 600 litres for trains.

To celebrate World Water Day, ISTOBAL is calling for water to be used responsibly in wash services for industrial and passenger vehicles.

The new Physical Recycler Plus achieves a water recycling rate of up to 88.8% 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.

Did you know that it takes more water to wash commercial vehicles than any other vehicle? For example, it takes 1277 litres of water to wash the exterior of a waste collection truck of 6 metres in length, 1162 litres for an 18-metre trailer, 871 litres for an 83-metre train, or 302 litres for a 14-metre bus.

Commercial vehicles also 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. 

Pioneer in the development of sustainable wash solutions

 With its commitment to protecting the environment and to developing wash machines that use water responsibly, ISTOBAL is a pioneer in the development of sustainable wash solutions for vehicles of all shapes and sizes.

The company's most notable achievements include a 94% reduction in the presence of hydrocarbons in the waste water from the wash process, a 45% reduction in the amount of water consumed in automatic machines for cleaning commercial vehicles, as well as reductions of around 40% in its rollovers and 33% in its Jet wash facilities.

The company has also developed a range of chemical products, ISTOBAL esens®, which has been awarded one of the most important and exacting sustainability certificates in the world (the Nordic Swan Ecolabel). It has also succeeded in cutting plastic consumption by 90% in the packaging used for car wash chemical products, all thanks to the specialist range of super-concentrated products known as Xtract.
