Ekster and Associates is a pioneer in providing turnkey control and expert systems such as SRTmaster for SRT control, D.O.master for D.O. control, and ASASC for a comprehensive activated sludge process control. In the hands of activated sludge operators our SRT control, D.O. control and other control/expert systems are effective and reliable tools that help to solve foam and settling problems and make operation more efficient because they combine process expertise with power of on-line measurements and advanced computing.

Designed with a combination of expert knowledge in wastewater treatment process, control theory, and equipment operation, our award winning technology is a perfect fit for new and existing treatment plants that want to improve efficiency and reliability of the activated sludge process. We use open control architecture, and our revolutionary automation technology can be utilized in a combination with most brands of control hardware and software.

In addition to innovative automation technology we offer a unique service aimed at optimization of set points (target values) for such parameters as solids retention time (SRT), dissolved oxygen (D.O.) or oxygen purity, and clarifier sludge depth. This service guarantees that our control systems maintain set points that provide peak level of performance of any activated sludge process.
