Article
Many biological methods are currently used to treat wastewaters, such as e.g. aerobic, anaerobic, sequencing batch reactors, biofilters. However, these technologies are limited by low nutrient removal efficiency, high energy and large area requirements. Hereby, the intermittent cycle extended aeration system (ICEAS), or continuous flow sequencing b...
Article
This study investigated the effects of two local plants (Wedelia Trilobata-WT, Axonopus Compressus-AC), feeding patterns (continuous and intermittent), and types of bed media (sand and charcoal) on the treatment performance of shallow bed subsurface flow wetland roofs (WRs). Results showed that changing plant from AC into WT led to an increase in r...
Article
Wastewater containing a high concentration of organic and emerging pollutants has been and remains a common and urgent issue, though many conventional methods are losing their effectiveness due to wastewater's chemical complexity. Electron beam (EB) is a common type of irradiation used in wastewater treatment, as it has the ability to create free r...
Article
Macadamia nutshell is a new absorbent material for wastewater treatment. This work is a report on the synthesis of activated carbon as an absorbent materials prepared from macadamia nutshells using H2SO4 and K2CO3 as activating agents for methylene blue (MB) removal in water. The results show that MB adsorption capacity reaches its highest at 250.2...

Currently, electrochemical oxidation is a very efficient method to treat many types of wastewaters. Under the effects of electrical current, toxic or non-biodegradable substances will be oxidized to become biodegradable or completely oxidized to CO2 and H2O. With the strengthening of environmental discharge legislations, tannery wastewater may have...
Article
Leachate is known with high concentration of organic substances and nitrogen, which are extremely toxic to the environment. Recently, electrochemical oxidation has received much attention on account of its low cost, feasibility, environmental friendliness, and excellent in contaminants removal in wastewater. The present study reported the first tim...
Article
The presence of hydrogen sulfide (H2S) in biogas negatively affects human health and corrodes metal. Therefore, the removal of H2S from biogas before using is an essential requirement in many cases. Recently, biotrickling filters (BTFs) have been widely applied to the treatment of H2S on both laboratory and industrial scales. However, BTFs method a...
Article
The principle of subsurface arsenic removal (SAR) from groundwater is based on oxidation and adsorption reactions by infiltrating oxygen into the anoxic aquifer and the immobilization of arsenic (As) onto freshly formed iron (Fe) oxides. In this study, a pilot-scale plant for SAR has been subject to long term testing in the Mekong Delta, Vietnam. I...
Article
Textile wastewater, especially when the dyeing section is involved, is remarkably polluted, characterized by a high value of chemical oxygen demand (COD) and color. The process to treat them currently is mostly biochemical and due to the heavy load, the process is remarkably expensive or needs a lot of steps. This research is launched in order to i...
Article
Tannery wastewater is known to contain high concentrations of organic compounds, heavy metals, nitrogen, sulphur, chromium, and many other chemicals. Both aerobic and anaerobic biological approaches have been proven ineffective in the treatment of tannery wastewater due to the high salinity of and toxic chemicals contained within the medium. Electr...

This study investigated if biochar, a low-cost carbon-rich material, can be modified with reactive materials for decolorization of dyeing wastewater. Two types of rice husk biochars were produced by using different processes of gasification and pyrolysis in limited air condition. The biochars were first magnetized and then modified with nano-scale...
