Fresh water source scarcity in arid and semiarid area is limitation factor for saline-sodic soil reclamation. The reusing of agricultural drainage and industrial wastewater are preferred strategies for combating with this concern. The objective of current study was evaluation in application of industrial sugar manufacture wastewater due to high soluble organic compounds in saline-sodic and sodi...

This tutorial review will focus on the removal of organic pollutants from the aqueous phase by mesoporous silica. After a brief discussion about mesosilica formation (MCM-41 and SBA-15) and silica surface modification, the review will focus on the use of mesosilica for the removal of (i) organic compounds, (ii) organic dyes, or (iii) pharmaceuticals from aqueous solutions.

The generation of disinfection by-products during water treatment can be controlled by reducing the levels of precursor species prior to the chlorination step. The Natural Organic Matter (NOM) is the principal organic precursor and conventional removal of pollutants such as coagulation, flocculation and filtration do not guarantee the total NOM removal. In this study the degradation of NOM mode...

Organic contaminants in shale gas flowback and produced water (FPW) are traditionally expressed as total organic carbon (TOC) or chemical oxygen demand (COD), though these parameters do not provide information on the toxicity and environmental fate of individual components. This review addresses identification of individual organic contaminants in FPW, and stresses the gaps in the knowledge on ...

This paper evaluates the feasibility of using shredded tires for removal of organic compounds from landfill leachate. From the batch sorption isotherm experiments, tire chips were found to have 1.4% to 5.6% of the sorption capacity of granular activated carbon on a volume basis. The sorption equilibrium occurred within 2 days for 0.6-, 1.3-, and 2.5-cm size tire chips. The capacity of tire chip...

Adsorption on activated carbon is currently the most frequently used technology to remove organic chlorinated pollutants from wastewaters. The present study examines the ability of five commercially available types of activated carbon to remove organic chlorinated compounds from the effluent of a chemical plant. The various types were tested on the basis of Freundlich adsorption isotherms for 1...

Phenol and it derivatives are considered as one of the priority pollutants in waste water, because they are harmful to organisms even at very low concentrations. The control as well as removal of these organic compounds has become an important issue due to stringent measures introduced by various countries to enforce regulations concerning wastes originating from various industries. Hence, wast...

Raw surface and ground waters used for drinking purposes can vary markedly in their chemical and biological composition. Inorganic content (such as salt, bicarbonate, clay and metal ions), organic content (natural organic matter and anthropogenic compounds, including pollutants) and micro-organisms present in raw water are key drivers for treatment processes that provide for safe and aesthetica...

The removal of trace organic compounds (TrOCs) by a novel membrane distillation-thermophilic bioreactor (MDBR) system was examined. Salinity build-up and the thermophilic conditions to some extent adversely impacted the performance of the bioreactor, particularly the removal of total nitrogen and recalcitrant TrOCs. While most TrOCs were well removed by the thermophilic bioreactor, compounds co...
