Treatment of effluents from Food Services Establishment (FSEs) by Physico-chemical processes: a case study for Trinidad & Tobago [PDF]

open access: yesJournal of Biological Engineering
Background Effluents from Food Services Establishments (FSEs) contain primarily Fats, Oil and Grease (FOG) which severely impact on sewers and the environment when released in high concentrations.

Coagulation of humic-kaolin-pacl aggregates

open access: closedWater Science and Technology, 2003
Water treatment residual flocs are fractal-like aggregates made of many initial aggregates. We investigated in this study the coagulation dynamics for the humic-mineral-polyaluminium chloride (PACl) aggregates using small-angle light scattering techniques and the free-settling test.

Al(III) speciation distribution and transformation in high concentration PACl solutions [PDF]

open access: yesJournal of Environmental Sciences, 2006
Effects of Al(III) concentration and pH on the speciation of Al(III) in polyaluminum chloride (PACl) solutions especially on the Al13 fraction were investigated. A series of PACl samples were prepared over the range of Al(III) concentration from 0.01 to 2.0 mol/L with the B (OH/Al ratio) value from 1.0 to 2.5 by forced hydrolysis of AlCl3.

Modelling turbidity removal by poly-aluminium chloride coagulant using gene expression [PDF]

open access: yesAdvances in Environmental Technology, 2021
Coagulants are used in drinking water treatment plants to increase the size of particles and to help make them bigger and more able to settle at the later stages of the process.

Speciation stability of inorganic polymer flocculant–PACl [PDF]

open access: yesColloids and Surfaces A: Physicochemical and Engineering Aspects, 2004
The speciation distribution, physico-chemical properties of coagulants, and principles for their further species transformation under various water and wastewater treatment conditions are of paramount importance in coagulation processes. In this paper, the effect of various factors on the speciation transformation of typical inorganic polymer ...
