Adsorption of Mn(ii) ions from wastewater using an AgNPs/GO/chitosan nanocomposite material.

Water contaminated with heavy metal ions is extremely poisonous and threatens living organisms. Therefore, scientists place a premium on removing heavy metal ions from water that has already been contaminated. Removing metal ions from water typically involves the use of nanomaterials.

Fe(iii) and Cr(vi) ions' removal using AgNPs/GO/chitosan nanocomposite as an adsorbent for wastewater treatment.

Heavy metal ions in water refer to significant risks to the biological system due to their high toxicity. Therefore, the decontamination of water polluted by heavy metal ions attracts significant interest of researchers. Adsorption by nanomaterials has been a widely used technique for removing heavy metal ions from water.

An integrated bioaugmentation/electrocoagulation concept for olive mill wastewater management and the reuse in irrigation of biofuel plants: a pilot study.

A consortium of highly degrading microorganisms was used in an integrated bioaugmentation/electrocoagulation process for treating olive mill wastewater. The system was investigated for treating 1 m day, at a pilot scale, for 2 years; hydraulic loading rate and organic loading rate were 2880 l m day and 37,930 g COD m day, respectively. Average removal efficiency for COD, oils, and total phenols was 63.

Actinomycetes in rice straw decomposition.

Actinomycetes are well known as lignocellulose decomposers. Forty-two cellulolytic actinomycete isolates have been recovered from soil. Those were identified to the genus level as: Streptomyces (26 isolates), Nocardiopsis (5 isolates), Micromonospora (4 isolates), Nocardioides (4 isolates) in addition to three isolates tentatively identified as Nocardia, Kibdelosporangium and Saccharomonospora.
