  • White paper - Chemical feed control

    The controls, alarms and external contacts are shown on the drawings. As the amount of chemical needed to neutralize the wastewater varies exponentially from neutral pH 7, special consideration must be given to control overshooting the pH. Chemicals, especially viscous caustic soda, must be fully mixed in the compartment before more is added. Rather than modulating the pump settings, the pump is ...

  • Chemical free, ultrasonic algae control

    Among the numerous applications of ultrasound, the approach is used in the field of water treatment. In this scenario, forces other than cavitation forces are being used to achieve a certain goal. An example of such ultrasound systems which can be found on the market are the LG Sonic systems,which are manufactured to suppress algal growth and biofilm formation. The ultrasounds produced by using ...

  • Modelling and simulation framework for pollution control of chemical processes

    During process design, it is possible to evaluate and control pollution that might occur during actual operation. This paper presents computer-aided design framework that enables the design team to define process design model elements and to measure possible pollution at each design step using performance indexes of pollution measures as mapped to process variables. Modelling methodology, called ...

  • Case study - Neutralization basin odor control for agricultural chemical production

    Challenge: An agricultural plant located in the Midwest manufactures herbicides, pesticides, fungicides, and insecticides. Strict environmental regulations require the company to capture and neutralize all surface runoff and grey water produced at the plant before disposing into the municipal system. In addition, air permits prohibit any odors to cross their fence lines. As ...

  • Real time control for reduced aeration and chemical consumption: a full scale study

    The use of the activated sludge process (ASP) for the nitrification/denitrification of wastewaters is commonplace throughout the UK and many other parts of the industrial world. Associated with this process are significant costs arising from aeration requirements and for selected sites, the need to provide an external carbon source. These costs can constitute up to of 50% of the total running ...
