  • Influence of feed quality on seawater reverse osmosis performance

    The trouble-free operation of a Reverse Osmosis (RO) plant relies on the quality of the treated feed water, which highlights the need for optimisation of the pre-treatment steps. The quality of raw seawater varies with time in terms of suspended and colloidal load, along with the dissolved salt content. In a conventional pre-treatment scheme, consisting of clarification and particulate and micron ...

  • Improved Anaerobic Digestion Feed Systems and Concepts

    The sludge feed systems for anaerobic digestion facilities at wastewater plants in North America have been and continue to be modified and upgraded for a variety of reasons. These reasons include operational problems and issues, evolution from prior primary-sludge-only digestion facilities, performance-based reasons, regulatory-based reasons, and include the desire to improve the digestion ...

  • Improvement of multi-parameter-based feed-forward coagulant dosing control systems with feed-back functionalities

    Coagulant dosing control in drinking and wastewater treatment plants (WWTPs) is often limited to flow proportional concepts. The advanced multi-parameter-based dosing control systems have significantly reduced coagulant consumption and improved outlet qualities. Due to the long retention time in separation stages, these models are mostly based on feed-forward (FF) models. This paper ...
