Providing a Financial Boost and Water Conservation

The recession has hit every state hard. But the recession, and the damage it has done to the workforce, has seriously ravaged the state of Michigan.

“In a climate like the one we have in Michigan, with all the salt and the changing seasons, trucks take a lot of abuse when they’re on the roads,” says Laackman. “There is a lot of truck washing going on. The water reclamation system uses that water again and again. It cuts down on water costs significantly. It essentially ends up paying for itself after a few years. That’s very important for anyone keeping an eye on their costs.”

The system is versatile enough, so that it can wash the distribution center’s route delivery trucks, merchandising vans, and, even, company cars, says Kelly Spielmaker, vice president of TBW Consultants Inc., in Naples, FL, the company that sold the SoBrite system to Fabiano Brothers.

In addition to making economic sense for the company, the truck wash system is also an example of a “green” feature, Spielmaker says. This is something that more companies are embracing, he says.

By using the water reclamation system, Fabiano Brothers is not consuming as much water and not discharging as much into the area’s sanitary sewers, Spielmaker says.

“This system is not something that you see every day installed at a private company,” explains Spielmaker. “It’s pretty unusual in my experience. It’s not only going to save Fabiano Brothers significant money over the years in water and sewer costs, it’s also good for the environment.”

The water reclamation system provides recycled water that is used as employees wash the facility’s trucks and other vehicles. Employees, though, still use city water to rinse the vehicles. It is this water that the reclamation system collects and recycles.

The SoBrite Filtermatic 3B incorporates both underground and aboveground tanks to filter water down to roughly six to 10 microns.

The water that is used during the wash cycle collects in a three-sided underground tank that holds a total of 1,000 gallons of water. Once that water is filtered, it is sent via a sump pump up into the water-reclamation tanks that sit above ground. These two tanks each hold 500 gallons of clean water. The system continuously filters the water as vehicles are washed.

The filtration system itself is unique. The SoBrite Filtermatic 3B relies on crushed glass to clean the water. The system uses a positive and negative ion charge to attract the heavier dirt particles and globules, which stick to the crushed glass as the water flows over it.

To Spielmaker, crushed glass is the ideal type of filter medium.

“This is a type of filter medium that can be used over and over again,” says Spielmaker. “It doesn’t have to replaced very often. If you look at the older systems on the market, systems with older technology, they use a lot of carbon or multi-media filters to absorb the waste stream. That’s fine, but those filters have to be replaced every six months or once a year. That is much more maintenance for a company to have to worry about. It’s more costly, too.”

The system self-cleans its crushed-glass filter by automatically backwashing the dirt load off the filter bed every evening. This backwash is sent to a separate aboveground holding tank. Once the sand, dirt, and hydrocarbons removed from the glass fill that tank, employees do have to pump it out and dispose of it.

Ruder says that crushed glass is a natural choice for his company’s water reclamation systems.

Glass is a non-porous material, but is also very smooth on its outside, Ruder adds. As the water reclamation system washes the dirt and oil in untreated water over the filter bed, the glass, because it lies too tightly packed together, grabs the dirt materials while letting now-clean water flow through.

Then, when the filter bed is backwashed, because of its porous nature, it allows the dirt and contaminants to flow easily out into a separate storage tank.

This makes glass a better choice than an alternate filter material such as silica sand, Ruder says.

“Silica sand is a non-porous material,” says Ruder. “But it has a rough surface on its outside. Go out and pick up a piece of gravel from the road, and you’ll see that it’s very rough. The oils and dirt, then, that we are filtering out of it will start sticking to it when we backwash.”

The crushed glass used in the SoBrite system comes in a variety of colors, from green, made up of crushed 7-Up bottles, to brown, made up of crushed beer bottles. Before the filter bed is backwashed, the crushed glass is so dirty, you can no longer tell what color it started out as, Ruder says. Next Page >
