Evaluation of the Efficiency of Bio-Polymers Derived from Desertic Plants as Flocculation Agents
Chemical Engineering Transactions, 2016 In the treatment of wastewater, flocculation is one of the most used processes, which aims to eliminate colloidal particles cannot be removed by other methods; Traditionally it has been used aluminum or iron salts and synthetic polymer, which generate ...

A pH-based pedotransfer function for scaling saturated hydraulic conductivity reduction: improved estimation of hydraulic dynamics in HYDRUS [PDF]
, 2019 Hydraulic conductivity is a key soil property governing agricultural production and is thus an important parameter in hydrologic modeling. The pH scaling factor for saturated hydraulic conductivity (Ks) reduction in the HYDRUS model was reviewed and ...

Flocculated meltwater particles control Arctic land-sea fluxes of labile iron [PDF]
Scientific Reports, 2016 AbstractGlacial meltwater systems supply the Arctic coastal ocean with large volumes of sediment and potentially bioavailable forms of iron, nitrogen and carbon. The particulate fraction of this supply is significant but estuarine losses have been thought to limit the iron supply from land.

Iron flocculation stimulates biogas production in Microthrix parvicella-spiked wastewater sludge [PDF]
International Journal of Environmental Science and Technology, 2014 Municipal wastewater sludge has been used for fertiliser and biogas production for several decades. Chemical compounds such as iron and aluminium are common coagulants used in wastewater treatment plants to remove suspended solids, phosphorus and micro-organisms.

Tannins from cashew tree (Anacardium occidentale) bark as a flocculant for water clarification
Revista Ambiente & Água, 2022 Concern about the overexploitation of natural resources has increased in recent decades, especially involving water and its treatment. Paradoxically, one of the sources of water pollution is the treatment itself, due to the use of chemical flocculants ...

The Impact of Capsid Proteins on Virus Removal and Inactivation During Water Treatment Processes [PDF]
, 2015 This study examined the effect of the amino acid composition of protein capsids on virus inactivation using ultraviolet (UV) irradiation and titanium dioxide photocatalysis, and physical removal via enhanced coagulation using ferric chloride.

Coagulant recovery and reuse for drinking water treatment [PDF]
, 2016 Coagulant recovery and reuse from waterworks sludge has the potential to significantly reduce waste disposal and chemicals usage for water treatment. Drinking water regulations demand purification of recovered coagulant before they can be safely reused ...
