Önemli bir bileşeni hümik asitler (HA) olan sulardaki doğal ornaik maddeler (DOM) uğradıkları fiziksel, kimyasal ve biyolojik değişimler sonucunda arıtma tesislerinde çeşitli problemlere sebep olmaktadırlar. Konvansiyonel arıtım prosesleri bu bileşiklerin giderimde yetersiz kaldıkları için ileri ile giderimleri hedeflenmektedir. Son yıllarda en dikkat çekici yöntemlerden biri de katalitik ozonl...

Micro-polluted water, which is widespread in rural areas, poses a serious health risk. To address this issue, we propose three-dimensional biofilm electrode reactor with triple-layer particle electrodes (TL-BERs) for the decentralized and small-scale treatment of micro-polluted water. The first second layers electrode, granular activated carbon (GAC) biological ceramsite (BC), respectively, are...

South Kalimantan-Indonesia is in the Southern part of Borneo which almost half population lives remote areas. Geographically, people are isolated and have poor access to electricity as well a clean water supply. It very essential ensure availability produced from peat overcome future shortages. This work performs fabrication multi-channel silica-based membranes applied for ultrafiltration demon...

A methodology to i) assess the feasibility of water disinfection in fresh-cut leafy greens wash water and ii) to compare the disinfectant efficiency of water disinfectants was defined and applied for a combination of peracetic acid (PAA) and lactic acid (LA) and comparison with free chlorine was made. Standardized process water, a watery suspension of iceberg lettuce, was used for the experimen...

All reagents were purchased from Aldrich, AlfaAesar, Sino Biologial Inc or Lumiprobe and were used as received. Where described below Pet. refers to petroleum ether (40–60 °C). All reactions were monitored by thin-layer chromatography (TLC) on pre-coated SIL G/UV254 silica gel plates (254 m) purchased from VWR. Flash column chromatography was carried out with Kiesegel 60M 0.04/0.063 mm (200–40...

Monitoring the removal of organic micropollutants (OMPs) in advanced wastewater treatment facilities requires expensive and time-consuming analytical methods that cannot be installed online. Spectroscopic techniques such as fluorescence excitation/emission spectroscopy were demonstrated to offer potential for monitoring OMPs conventional plants or ozonation pilots but their application activate...

Combined sewer overflows (CSO), generated during the wet weather flow from combination of inflow and stormwater runoff in system, result an overflow untreated wastewater which might ultimately contain different micropollutants (MPs). In this study, a coagulation-flocculation-sedimentation (CFS) pretreated CSO spiked with MPs was treated by catalytic ozonation using carbon, iron, peroxide-based ...

One of the major challenges in reusing cooling tower blowdown water (CTBD) utilizing membrane processes is its remaining organic compounds, e.g., humic substances leading to biofouling. Besides, possible abundance chloride CTBD imposes concern formation chlorinated by-products. To choose a pre-treatment process for studied composition, various advanced oxidation (AOPs), including electrooxidati...

The performance of ion exchange (IX) resin for organics removal from wastewater was assessed using advanced characterisation techniques for varying doses of IX. Organic characterisation using liquid chromatography with a photodiode array (PDA) and fluorescence spectroscopy (Method A), and UV254, organic carbon and organic nitrogen detectors (Method B), was undertaken on wastewater before and af...
