• There is an increasing potential for photo-assisted EAO disinfection processes. • Disinfection at the electrode/solution interphase depends on the anode material. • Indirect disinfection can be carried out by a variety of electro-generated oxidants. • Solar EAOPs are effective and cost competitive approaches for pathogen inactivation.

Haloacetaldehydes (HALs) are the third prevalent group of disinfection by-products (DBPs) by weight in drinking water, and their cytotoxicity and genotoxicity are higher than regulated DBPs. In order to understand their formation mechanism during chlorination and ozonation-chlorination, this study examined the reaction kinetics of chloral hydrate (...

The presence of unidentified organofluorine compounds (UOF) has been investigated in recent publication, but their environmental occurrence is still poorly understood. Fluorine mass balance analysis was performed on environmental samples from lake Mjøsa and river Alna (surface water (n = 9), sediment (n = 5) and fish liver (n = 4)) and sewage sampl...

Polycyclic aromatic hydrocarbons derivatives (dPAHs) were reported to be more mutagenic than parent analogues, however, studies that involving dPAHs in environmental samples are still limited. Thirty-six polycyclic aromatic compounds (PACs; 17 parent PAHs, 1 alkyl-PAH, 6 oxygenated PAHs, 6 azaarenes, 3 sulfur-containing heterocyclic PAHs, and 3 oxy...

Pyrolysis of agricultural biomass is a promising technique for producing renewable energy and effectively managing solid waste. In this study, groundnut shell (GNS) was processed at 500 °C in an inert gas atmosphere with a gas flow rate and a heating rate of 10 mL/min and 10 °C/min, respectively, in a custom-designed fluidized bed pyrolytic-reactor...

The Phosphorus (III) derivatives, named Phosphonates, include congeners with properties as fungicides that are effective in controlling Oomycetes. Examples are organic compounds like Fosetyl-Al [Aluminium tris-(ethylphosphonate)] and salts formed with the anion of phosphonic acid [(OH)2HPO] and Potassium, Sodium and Ammonium cations. According to I...

Phytoremediation as an efficient and eco-friendly soil detoxification method has received widespread attention. In this study, two newly screened Chromium (Cr) reducing strains (Bacillus sp. AK-1 and Lysinibacillus sp. AK-5) were used to remediate Cr contaminated soil in conjunction with the application of hyperaccumulator tall fescue (Festuca arun...

This study investigated the feasibility of combining natural ventilation and animal disturbance in constructed wetlands (CWs) and the joint effects on oxygen transfer, microbial activity, organics, and nitrogen removal. The results showed that natural ventilation extended the habitat depth of earthworms by approximately 10 cm by significantly impro...

The use of membranes in desalination and water treatment has been intensively studied in recent years. The conventional membranes however have various problems such as uncontrollable pore size and membrane properties, which prevents membranes from quickly responding to alteration of operating and environmental conditions. As a result the membranes ...
