    BioChem Contributes to Chesapeake Bay Clean-up

    June 13, 2013

    Three recently upgraded wastewater treatment plants in the Chesapeake watershed have incorporated BioChem’s BIOS into their control strategy to improve their Total Nitrogen effluent numbers and meet the strict Chesapeake NPDES limits. At the same time, they are reducing their overall energy consumption and reducing their O&M expenses to benefit the local ratepayers.

    Case studies are being prepared and will be posted when they become available. For more information, please contact us.

Our Products
The BioChem Difference

BioChem has two core products that, together or individually, focus on the optimization of aeration and secondary treatment of wastewater.

  • The Bioprocess Aeration Control System (BACS):

    BioChem has developed an advanced aeration control system to effectively control the residual dissolved oxygen (DO) concentration in each aerobic zone of an activated sludge wastewater treatment process.

  • The Bioprocess Intelligent Optimization System (BIOS):

    The Bioprocess Intelligent Optimization System (BIOS) is an integrated hardware and software system that enables real-time monitoring and control of wastewater treatment operations based on the dynamically changing biological activity occurring in the bioreactor. The BIOS controls the secondary treatment process to provide optimal conditions for microbial treatment.
