Monitoring and control of redox processes are key to operate wastewater chemical treatment plants at high-loading-rate whilst rejecting concentration and composition disturbances. Carbon dioxide concentration and oxidationreduction potential (ORP) are selected as key inferential measurements of oxidation kinetics and oxidant reagent consumption. An extremum-seeking control cascade is proposed f...

Water clarity is a key parameter of coastal ecology, as well as being important to some near-shore Naval operations. The clarity of the water column depends upon the depth-dependent distribution of the inherent optical properties and the geometric structure of the light field (an apparent optical property). Our long-term goal is to develop the remote sensing techniques, data analysis, and model...

The aim of the study was to investigate decolourization Methylene Blue (MB) in aqueous solution using advanced oxidation processes (AOPs) and biosorption comparatively. Photocatalytic MB studied TiO2 as catalyst. photocatalytic by direct UV irradiation alone, only TiO2/UV investigated. It found that process increased with decreasing pH, rate also presence when compared alone. Decolourization Fe...

Advanced oxidation processes (AOPs) based on oxidants have attracted attention for the degradation of organic pollutants. The combination chalcopyrite with such as persulfate, peroxide, percarbonate, and others shows promise a system due to its ability activate through various pathways, leading formation numerous radical non-radical species. In this review, generation sulfate (SR) hydroxyl (HR)...

• Probe based total OH quantification is unlikely but frequently reported. Uncertainty of make it an unsuitable performance indicator. Fate was deconstructed to identify a suitable utilised by the probe [P] process specific Performance acoustic cavitation and photocatalysis compared on [P]. In-situ hydroxyl radical production characteristic advanced oxidation processes (AOPs) its crucial for as...

Advanced oxidation processes (AOPs) play a vital role in attenuating contaminants of emerging concern (CECs) during potable water reuse. AOPs are conventionally performed by irradiating with 254-nm low-pressure (LP) mercury-vapor (Hg) ultraviolet (UV) lamp along chemical treatment. Compared UV-C light treatment (200–280 nm), vacuum-UV (V-UV) (100–200 nm) is advantageous terms hydroxyl radical g...

Advanced oxidation procedures (AOPs) refer to a variety of technical that produce OH radicals sufficiently oxidize wastewater, organic pollutant streams, and toxic effluents from industrial, hospital, pharmaceutical municipal wastes. Through the implementation such procedures, (post) treatment waste leads products are more susceptible bioremediation, less possess load. The basic mechanism produ...

Homogeneous photodriven advanced oxidation processes (HP-AOPs) have been increasingly investigated in past years as a possible alternative solution to conventional tertiary treatment methods of urban wastewater.

As an emerging light source, ultraviolet emitting diodes (UV-LEDs) are adopted to overcome the shortcomings of conventional mercury lamp, such as pollution. The degradation chloramphenicol (CAP) using three UV-LED-based advanced oxidation processes (AOPs)—UV-LED/persulfate (UV-LED/PS), UV-LED/peroxymonosulfate (UV-LED/PMS) and UV-LED/chlorine—was investigated. Results indicate that CAP can be m...
