CERTOWASH is an innovative, completely ecological system, self-sufficient in terms of energy requirements and with no added chemicals. Its technology, based on hybrid ozonation, uses only renewable energies and oxygen from the ambient air. The proposed system is equipped with an in-line water quality analyzer at the system inlet and outlet. This analyzer ensures total safety of treated water quality. Indeed, if the desired treatment standards are not met, the system automatically recycles the effluent to achieve the desired objective. The system is maintained and monitored by an application (which manages the system remotely) and an associated robot.

The system will be installed on site in a mobile technical area. It will be supplied with wastewater from a tank that is often buried and collects all the wastewater. Treated water is stored in a clean water tank. In this way, all wastewater is treated and stored for later reuse. This principle enables the carwash to operate in a water loop, without discharging any pollution. Water top-up in the event of leakage and/or evaporation can be provided by the rainwater reserve already collected in the wastewater tank, oversized in relation to the total quantity of wastewater per day. The water top-up, estimated at a maximum of 10%, may be drinking water if necessary.
