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 ...

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 ...

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 ...

Integrated process control for recirculating cooling water treatment in the coal chemical industry

This work focused on the integrated process of the recirculating cooling water (RCW) treatment to achieve approximate zero emission in the coal chemical industry. The benefits of fractional and comprehensive RCW treatment were quantified and qualified by using a water and mass balance approach. Limits of cycle of concentrations and some encountered bottlenecks were used to ascertain set target ...
