Ecolo-Chief Wastewater Treatment Systems utilize the activated sludge treatment process which was developed in the early 1900's and is widely accepted throughout the United States and the world. This process is both an effective and efficient method of treating wastewater. There are several effective derivatives of the first activated sludge process with two of the most common being the Conventional and Extended Aeration systems. Chief Industries manufactures both of these systems.
Basic Engineered Systems: The Ecolo-Chief Systems have capacities ranging from 7000 - 354,900 gallons per day. Using the modular tank concept, systems can be engineered for capacities up to 750,000 gallons per day.
