In this respect, the modeling of the organic matter removal kinetics from municipal sewerage in horizontal subsurface flow CWs was carried out using a conventional first-order model and sigmoidal k-n model [[12]]. Water is an essential natural compound on earth; all life forms on our planet need water to function properly. The presented water management research in this Special Issue aimed to assess natural water quality in different areas, i.e., Brazil, Palestine, and China. [Extracted from the article]

Nano-zeolite is an innovative class of materials that received recognition for its potential use in water and tertiary wastewater treatment. These applications include ion-exchange/sorption, photo-degradation, and membrane separation. The aim of this work is to summarize and analyze the current knowledge about the utilization of nano-zeolite in these applications, identify the gaps in this field, and highlight the challenges that face the wide scale applications of these materials. Within this context, an introduction to water quality, water and wastewater treatment, utilization of zeolite in contaminant removal from water was addressed and linked to its structure and the advances in zeolite …

© 2017, Chemical Publishing Co. All rights reserved. Heterogeneous photocatalysis has proved to be a successful method for the degradation of water pollutants. In this work, the photocatalytic decolourization of acid orange 7 was performed by cobalt-doped titanium dioxide (Co-doped TiO2). The Co-doped TiO2 was synthesized and characterized using X-ray diffraction, scanning electron microscopy, energy diffraction spectroscopy, UV-visible reflective dispersion spectroscopy and adsorption of nitrogen gas. The acid orange 7 was prepared as a synthetic textile wastewater at three initial concentrations (24, 34 and 44 mg/L) with three photocatalyst loadings (0.025 g, 0.050, 0.1 g/100 mL acid orange 7). Results …

Dyes are coloured substances that can be applied to various substrates such as textile materials, leather, paper and hair. The usage of dyes has continuously increased in many industries but the removal of this pollutant remains as a problematic issue as they are generally stable to light and oxidizing agents and are resistant to aerobic digestion. This literature review paper provides and lists several low cost adsorbents to serve as an alternative method for dye removal. Adsorption using low cost materials can be viewed as a sustainable treatment process because most of these materials are of naturally occurring, locally available …
