The current work aimed to evaluate the feasibility of including ozone (O3)-based advanced oxidation processes (AOPs), as an intermediate step, in a multistage treatment system for non-biodegradable sulphur-rich leachate from hazardous industrial solid waste landfill (HISWL), combining chemical and biological technologies. O3-based AOPs covered perozonation (O3/H2O2), photo-assisted ozonation (O...

Coagulation-flocculation constitute the backbone process in most water and wastewater treatment plants. This study focused on determining optimum coagulant dose for moringa oleifera seed extract, zeolite, ferric chloride, chitosan aluminium sulphate coagulants through coagulation, flocculation sedimentation process. It also ascertain which has potential higher removal of Cd, Cu, Fe, Mn, Pb Zn. ...

A quick-cooking rice, produced from broken rice, is a convenient ingredient for complementary foods in Thailand. The rice is fortified with micronutrients including iron during the processing procedure, which can cause unacceptable sensory changes. A quick-cooking rice fortified with ferric ammonium citrate (FAC) or a mixture of ferrous sulphate (FeSO4 ) and ferric sodium ethylenediaminetetraac...

Abstract The aim of this paper is to identify a technique detoxify the industrial waste water using metal oxide nanoparticles. Waste from manufacturing or chemical processes in industries contributes pollution. Industrial usually contains specific and readily identifiable compounds. It destroys aquatic life reduces its reproductive ability. Eventually it hazardous human life. Most major have tr...

This paper describes studies on the recovery of metals from spent hydro-processing catalyst using mixed acidophilic culture in presence of pyrite. This culture was initially grown in the 9K medium (absence of 9 g/L Fe(II)) where ferrous sulphate (FeSO4) was replaced by pyrite, and then applied in this bioleaching study. Bacterial action on pyrite catalysed the formation of ferric ion (Feþ3), pr...

In this paper, we have proposed a simple method to covalently conjugate biotin to magnetic nanoparticles, which can be targeted to the tumour sites by using pretargeting approach with avidin or streptavidin. Magnetic nanoparticles of manganese ferrite were synthesized by alkaline coprecipitation of ferric chloride hexahydrate, ferrous sulphate heptahydrate and manganese sulphate monohydrate usi...

Microorganisms have been implicated in the release of arsenic into drinking water involving bio-electrochemical reactions. Iron reducer has been shown to release captive arsenic from insoluble ferric oxyhydroxide–arsenic oxide adduct. Sulphate reducing bacteria (SRB) and Enterobacteriaceae may play a similar role by releasing hydrogen sulphide. The case of arsenic mobilization in water may be c...

Many articles have been published on coagulant dosing in membrane bioreactors, though few have been long-term studies examining the treatment of real wastewater. This study summarises the results of a membrane bioreactor pilot-plant (flat sheet membrane, nominal pore size 0.03 μm) that treated real municipal wastewater for two-years. Both influence of phosphorus precipitation by ferric sulphate...

A simple, accurate and sensitive spectrophotometric method for the determination of Procaine penicillin (PP) is described. The method is based on charge-transfer reaction of PP with metol (N-methyl-p-hydroxy aniline) in the presence of ferric sulphate to form a purplewater soluble complex ,which is stable and has a maximum absorption at 510 nm .A graph of absorbance versus concentration shows t...
