The Excel Difference: We Recycle 80% of Our Water

After extensive pilot testing and evaluating various treatment technologies, we made the decision to install a Kemco Ceramic Microfiltration System (CMF) followed by a Reverse Osmosis (RO) system. The CMF removes all the prohibited contaminants: fats, oils, greases and suspended solids by filtration and does not require any treatment chemicals. However, there are still dissolved contaminants in the water such as BOD/COD and surfactants. These contaminants, while not prohibited in the sewer system are subject to surcharges. Water from laundries almost always exceeds these limits and incurs substantial surcharges. The (RO) system removes these dissolved contaminants to a level at which, if the water were to be discharged, would incur no surcharges.

What does this mean for you?
The quality of the water is so good that it can be recycled back into the laundry for all stages of the washing process. In fact, the water from the RO is better than the incoming city water, since it contains no hardness and is still warm. In fact, 80% of the water that would have normally gone to the sewer is recycled for cleaning. At the same time, we have also eliminated the waste water surcharges and enhanced our sustainability initiatives.
