History
ETS was incorporated in 1987 at its first offices at the Advanced Technology Development Center (ATDC) at the Georgia Institute of Technology. The Principals of ETS, G. Edward (Edd) Valentine, Jr. and Charles C. Ross, P.E., have extensive experience and knowledge related to the design and installation of industrial wastewater treatment systems. Both were members of the Research Faculty of the Georgia Tech Research Institute for over thirteen years, where they were involved in environmental research and education. ETS became a graduate member of ATDC in 1995 and moved its offices to their current location in Smyrna, Georgia. Today, ETS has a full-time staff of two principals plus five other design and support staff. ETS prides itself in providing quality, cost-effective environmental systems and services.

Activated SludgeThe activated sludge process is a biological wastewater treatment process that uses microorganisms, including bacteria, fungi, and protozoa, to speed up decomposition of organic matter. Activated sludge is an aerobic process requiring oxygen for treatment. As the microorganisms grow and reproduce, waste materials are removed. |

Process DesignETS design engineers can provide design services for physical-chemical and biological wastewater treatment systems. Whether as the design component of a traditional design-bid-build project, or as part of a turn-key design-build project, ETS engineers have the expertise and experience to design a successful system that achieves effluent goals while emphasizing operability. |

Treatability TestingTreatability testing is a service that allows ETS to help clients determine the suitability of a process or processes for treatment of wastes and provides design data for specification and design of a full-scale system. ETS provides laboratory, bench, and pilot-scale treatability testing services to help clients find the best solution to their waste treatment needs. Testing needs for a particular wastewater can vary depending on experience, so some ... |
