The feasibility of a heterogeneous Fenton Process (ZVI/H2O2) using commercial low-carbon-steel nails as the Zero-Valent Iron (ZVI) source was evaluated for first time removal natural organic matter (NOM) from surface waters with distinct physico-chemical characteristics. synergistic effect ZVI and H2O2 on process confirmed. Results showed similar efficiencies NOM in water samples Thames river R...

Bu çalışmanın temel amacı genotoksik, sitotoksik ve kanserojenik olduğu bilinen dezenfeksiyon yan ürünlerinden trihalometanların miktarının belirlenmesi için çoklu lineer regresyon analizi kullanılarak tahmin modelinin oluşturulması literatürde mevcut modelleme çalışmaları ile karşılaştırılarak en iyi belirlenmesidir. Tahmin modelinde kullanılan bağımsız değişkenler Isparta şebekesinde ölçülen ...

Artificial sweeteners (ASs), as a new emerging pollutant, the fate from wastewater treatment plants (WWTPs) to sea is growing concerned. In this study, distribution and polluted loading of six typical ASs were analyzed based on measurement in influent, primary effluent, secondary tertiary suspended particulate matter (SPM), sludge four WWTPs receiving waters near coast Shenzhen city, China. Ele...

Abstract As water resources become increasingly scarce, the concept of reuse is gaining importance. Recently, attention has been paid to use rainwater as an alternative resource. Part this study, laboratory-scale experiments were conducted evaluate effectiveness and efficiency ultrafiltration process. The aim research was assess influence pollutants from various roof coverings on process occurr...

The objective of this study was to develop an innovative and advanced integrated “membrane oxidation” system for the treatment domestic wastewater by coupling membrane bioreactor (MBR), nanofiltration (NF) ozonation. Five contaminants were selected (acetaminophen, carbamazepin, sulfamethoxazole, tetracyclin terbutryn). MBR effluent samples have been fully characterized using conventional analys...

Organic matter present in natural water is a serious problem during treatment terms of the possibility creating disinfection by-products (DBP). The new materials and processes are still analyzed order to improve efficient removal organic as well other pollutants from intended for human consumption. aim presented study was evaluate efficiency using various combined processes: (a) coagulation ads...

The Rietvlei Water Treatment Plant was extended with a granular activated carbon (GAC) filtration system after an exhaustive series of tests, which were started in 1994. Upon commissioning towards the middle of 1999, a year of close monitoring followed to measure the GAC performance at full-scale. After verification that the GAC does indeed ensure a high quality product under all conditions, th...

2016 © American Water Works Association JOURNAL AWWA OCTOBER 2016 | 108:10 Microfiltration (MF) membranes are low-pressure membranes that generally have pore sizes in the range of 1 to 0.1 μm. They can effectively reject bacteria, protozoa, and colloidal particles by size exclusion. The physical rejection of viruses and the dissolved fraction of natural organic matter (NOM) by MF (0.1 μm nomina...

Zeta potential was assessed as a tool to optimise pre chlorination and coagulation at Happy Valley WTP. Samples were obtained from jar tests using raw water spiked with green algal cells. Treatments including pre-chlorination, polyelectrolyte addition and alum dose were investigated. Results indicate that: pre chlorination of algal spiked raw water had a negative effect on zeta potential; alum ...
