Robust water quality controller for a reverse osmosis desalination system
This paper presents two-degree-of-freedom (2-DOF) robust loop-shaping control methodology to stabilize a reverse osmosis (RO) desalination system operating under significant uncertainties, external disturbances and measurement noises, and to reduce product water cost. This method has the advantages that no information about the plant uncertainty is required and it can deal with external ...

A coupled model for water resources allocation regarding water quality control
In this study, a fuzzy credibility constrained programming (FCCP) model is developed for water quantity and quality management with uncertainties in water quality parameters. The proposed method could reflect not only inexact uncertainties in the objective function, variables and parameters, but also fuzzy uncertainties in the right-hand side. Credibility levels which represent satisfaction ...

Optimized water softening systems thanks to quality-controlled regeneration
Novel water hardness monitoring For the production of soft water, ion exchange units with sodium chloride regeneration have been increasingly used for more than 50 years. The course and dynamics of the softening process depend on the ion exchange resins used, the proper regeneration processes, the removal quantities and their dynamics. These processes do not run constantly in practice, which is ...

4 Benefits of Industrial Wastewater Monitoring
Water quality monitoring has evolved significantly over the past decade. Today’s industrial manufacturers have access to technologies that are capable of monitoring various wastewater quality parameters and contaminants of concern in a simple and effective manner. A continuous stream of water quality information to a plant’s control system can provide significant value. Here are four ...

Application of Flow Cytometry for Microbiological Monitoring of Pharmaceutical Grade Water
Online Water Bioburden Analysis As the main excipient for the pharmaceutical industry, water is integral to patient safety and quality of pharmaceutical products (ISPE 2011). Colony Forming Units (CFU) are defined in the pharmacopoeias as the unit for assessing microbiological quality. CFUs are quantified using the traditional Heterotrophic Plate Count (HPC) method, a three to five-day process ...
