Two ecological fluidized beds provide final polishing. The system uses a single pump to get the water from the holding tank behind the factory to the living machine and a single blower to maintain oxygen level and move water within the system. Cedar Grove has also noticed substantial reductions in phosphorus and select chlorides. Water passes through the old absorption pond, which has become a wildlife habitat, and flows into the Honey Creek at rates below the required discharge limits. The living machine manages the company's water use of 7,000 gallons per day with about a three-day retention.
Plants assist the activated sludge processes mimicking the activity of natural wetlands.
Plants remove nutrients from the water and assist in transferring oxygen to the water. Cedar Grove Cheese started using surface plants in March 1999, at which time it saw a marked improvement in the stability and efficiency of the system. The company primarily uses tropical plants but has started experimenting with more marsh grasses and hydroponic herbs and vegetables. The plants are regularly harvested for resale and mulching. In addition, the living machine is home for several species of frogs, mussels, and bluegills.
