ISTOBAL reduces hydrocarbons in car wash wastewater by 94%

ISTOBAL reduces hydrocarbons in car wash wastewater by 94% thanks to its separation and retention technology.

Committed to the initiatives of World Water Day, the Spanish firm is a pioneer in developing sustainable car wash solutions with a low environmental impact and in reducing the use of water, energy and chemicals.

With the hydrocarbon separator, ISTOBAL has managed to retain hydrocarbons in the vehicles’ fuel and engines, preventing them from contaminating the water used in the wash process. With this equipment, water can also be reused in subsequent car wash services.

ISTOBAL has underlined the importance of avoiding the use or discharge of untreated water in washing processes, as one litre of oil pollutes 1,000 m3 of water (the equivalent of an Olympic swimming pool) or m2 of land (a football pitch).

ISTOBAL’s hydrocarbon separator conforms to European standard EN 858, DIN 1999 Class I. Available on all its car wash machines, this technology ensures effluents under 5 ppm (parts per million), not only complying with European standards on water disposal in public sewage, but also surpassing the set elimination levels in many cases.

ISTOBAL, committed to responsible water treatment

On the occasion of World Water Day -this year focused on wastewater issues- ISTOBAL recommends using hydrocarbon separators, an adequate dosing of chemicals, and the use of detergent degraders.

The Spanish company believes an environmentally friendly car wash station must use biological or physical water recycling systems to be able to reuse the water used in the wash process.

Likewise, they recommend to wash vehicles in proper car wash facilities to avoid environmental damage and oil spillage on the wash bay, and not to wash engines at the car wash station.

A pioneer in developing technologies that reduce water and energy consumption

In their commitment to the environment, the company has reduced water consumption in commercial-vehicle wash machines by 45% by increasing water pressure during the most critical wash phase, consumption-wise.

Its last-generation rollovers use 40% less water that previous ones thanks to new, less-absorbing materials used in brushes and the better distribution of the water circulation circuit, among other technologies.

The company has also managed to reduce water consumption by 33% in its jet washes thanks to a low-pressure operation and the low flow rate used with some programs. ISTOBAL also uses innovative recycling systems which help reuse 85% of the water used in each service.

Similarly, with its esens® chemical line, the Spanish firm has obtained the the ‘Swan Ecolabel’ -the ecolabel of Nordic countries- for its environmental friendliness, one of the most important and demanding sustainability certifications in the world.
