Water- and energy-saving washer designs for the 1990's ecology
A surface preparation machine is costly to run because of the water and energy it consumes.
If designed incorrectly, it can be even more costly, not only in money spent on higher water and fuel bills but also in money spent on higher chemical bills. When you use iron or zinc phosphate systems, you have to treat any wastewater before you dump it down a sewer. On that account, it's a good idea to find ways to cut down on water. After all, the less water you use, the less water you need to treat before you discharge it down a sewer.
