“…Additionally, mercury UV lamps are highly fragile, temperature variation sensitive, and they contain a large footprint. Thus, UV light emitting diodes (UV-LEDs) have been recently considered as a potential novel UV source offering features that could overcome the shortcomings of these lamps, including high durability, robust designs, lower voltage requirements, and lack of mercury (Chevremont et al., 2013; Würtele et al., 2011). However, studies applying UV LEDs for wastewater disinfection processes in real conditions are limited; in particular, there is a lack of case studies involving flow-through UV-C LED processes.…”

In many low-income countries, the poor conditions of sanitation systems have been a significant cause of mortality since they accelerate waterborne disease transmission. Developing sanitation systems in these countries is a pressing concern in both the public and private sectors. This research investigated a decentralized domestic wastewater treatment system using ultraviolet light-emitting diodes (UV-LEDs). Although UV-LED disinfection has become more widespread in recent years, it is a novel approach for domestic wastewater treatment. Domestic wastewater was pretreated by a low-cost pretreatment system with an inclined settler and a sand filter prior to feeding a novel flow-through UV LED reactor. At an inlet flow rate of 30 L/h, the COD, TSS, and turbidity of the effluent were 17.7 mg/L, 3.0 mg/L, and 3.9 NTU, respectively. UV transmittance at 285 nm was enhanced from 29.1% to 70.4%, improving the influent quality for UV LED disinfection. The flow-through UV LED reactor was operated at various flow rates from 10 to 50 mL/min, resulting in applied UV doses of 69.4 to 47.8 mJ/cm 2 respectively. These doses are sufficient for inactivating total coliforms in the wastewater to meet the water reuse guidelines for agriculture for both processed food crops and non-food crops. Fouling, which was observed starting at 2 d of operation, decreased the disinfection efficacy to 27% after 25 days of continuous operation. Of the fouling layer, 67% was attributed to organic matter, in contrast to previous fouling studies with mercury UV lamps in which the fouling layer consisted primarily of inorganic compounds. The fouling was reversed by off-line citric acid cleaning for 4 h after every 400 h of continuous operation.

“…It has really a number of benefits over conventional chemical treatment like no disinfectant residuals, insignificant development of disinfection by-products ( Aoyagi et al, 2011 , Dotson et al, 2012 , Lubello et al, 2004 , Mori et al, 2007 ). We can use low or medium-pressure mercury lamps most commonly used as a UV source in UV disinfection methods ( Beck et al, 2015 , Chevremont et al, 2013a ). Although, UV technology is nowadays used as surface treatment but it has number of limitations: (i) UV is not able to facilitate directly to the surface microorganisms due to the characteristic shallow penetration depth.…”

The dynamic production and usage of pharmaceuticals, mainly painkillers, indicates the growing problem of environmental contamination. Therefore, the monitoring of pharmaceutical concentrations in environmental samples, mostly aquatic, is necessary. This article focuses on applying screen-printed voltammetric sensors for the voltammetric determination of painkillers residues, including non-steroidal anti-inflammatory drugs, paracetamol, and tramadol in environmental water samples. The main advantages of these electrodes are simplicity, reliability, portability, small instrumental setups comprising the three electrodes, and modest cost. Moreover, the electroconductivity, catalytic activity, and surface area can be easily improved by modifying the electrode surface with carbon nanomaterials, polymer films, or electrochemical activation.
