At first, employees resisted the unit in favor of hand wiping. With the support of the supplier, the company spent 2 weeks teaching employees how to operate and maintain the system. Now, workers monitor chemical levels every morning. For example, they check the pH level, and if they get a reading of 3.0 or 4.0, they simply add another gallon of chemical, Montano said. The supplier also visits almost daily to monitor the system.
Workers also clean the filters daily.
At the end of the day, they use an oil skimmer to remove oils form the top of the tank. To keep the system clean, they switch tanks every 2 weeks. One holds water and the other hold chemicals. Every 2 weeks, workers replace the chemical tank with the water tank. Next, they ad a new tank for the water.
