background; turbidity removal using inorganic coagulants such as iron and aluminum salts in water treatment processes causes environmental and human health concern. historically, the use of natural coagulant to purify turbid water has been practiced for a long time. recent research indicates that descurainia sophia seed can be effectively used as a natural coagulant to remove water turbidity. m...

Super- and sub-critical water treatments have been of interest as novel methods for protein hydrolysis. In the present study, we studied the effect of sub-critical water (Sub-H2O, 300℃, 80 bar) treatment as well as super-critical water (Super-H2O, 400℃, 280 bar) treatment on the physicochemical properties of porcine skin (PS), which has abundant collagen. Porcine skin was subjected to pre-therm...

Additive main effects and multiplicative interaction (AMMI), as well various AMMI-derived statistics, Genotype, Genotype × Environment Interaction (GGE) models were employed on 24 sugarcane genotypes planted during two seasons (2017–18, 2018–19) under different induced salinity stress environments using saline water irrigation (iw) viz., E1 (Normal iw crop season 2017–18), E2 2018–19), E3 (4 ds...

Polymeric nanofbers, specifcally fabricated by electrospinning, offer viable means useful for a wide range of applications such as health, energy and environmental issues. However, among the mentioned sectors, desalination and water/wastewater treatment applications have been highlighted during the past decade. This article focuses on the present status and recent develo...

several common approaches are used for disinfection of water in this section, but using the approaches (e.g. chlorination) are accompanied with hazardous by-products and also lead to notable changes in odor and flavor of water. gamma irradiation as an emerging method has been encouraged currently by fao/who for water, wastewater and food treatment. coliform bacteria belong to common contaminant...

background: there are great interests in photocatalytic oxidation of contaminants using titanium dioxide in recent years. the main objective of this research was to study photocatalytic disinfection of coliform bacteria as water microbial pollution index using tio2 and a low pressure uv lamp in a batch reactor. methods: the polluted water was prepared by adding a colony of coliform in raw water...

in current work, cds/black carbon nanocomposites were successfully synthesized with the aid of chestnut and cadmium nitrate as the starting reagents. besides, the effects of preparation parameters such as reaction time, and precursor concentration on the morphology of products and removal of heavy metals (hg+2, pb+2) were studied by scanning electron microscopy images and batch adsorption mode....

background: nitrate is an acute and well-known hazardous contaminant, and its contamination of water sources has been a growing concern worldwide in recent years. this study evaluated the feasibility of nitrate removal from water using the traditional coagulants alum and ferric chloride with lower concentrations than those used in the conventional coagulation process. methods: in this research,...
