Enhancing the flocculation of stable bentonite suspension using hybrid system of polyelectrolytes and NADES
(
Elsevier B.V.
, 2022 , Article)
In this study, the influence of a hybrid coagulation/flocculation process on the electrokinetic of highly stable bentonite suspension has been examined. Choline chloride (ChCl) based natural deep eutectic solvent (NADES) ...
Choline chloride based natural deep eutectic solvent for destabilization and separation of stable colloidal dispersions
(
Elsevier B.V.
, 2021 , Article)
In solid-liquid separation processes, coagulation/flocculation is one of the most popular techniques in treating wastewater, as it is efficient, simple, and economical. Consequently, the formation of a new environment ...
Impact of aluminium acetate particles size on the gelation kinetics of polyacrylamide-based gels: Rheological and molecular simulation study
(
John Wiley and Sons Inc
, 2021 , Article)
Inorganically crosslinked polymers have been intensively implemented for conformance control treatments in oil and gas wells at low temperatures (<90°C) because of their faster gelation time compared to organically crosslinked ...
Enhancement of flocculation and dewaterability of a highly stable activated sludge using a hybrid system of organic coagulants and polyelectrolytes
(
Elsevier Ltd
, 2020 , Article)
This study investigates the influence of hybrid coagulation-flocculation system on the flocculation and dewaterability efficiency of a real highly stable activated sludge obtained from the membrane bioreactor tank of a ...
Rheological characterization of NA2CO3 activated calcium bentonite for oil and gas drilling applications
(
AIChE
, 2015 , Conference Paper)
Calcium bentonite was activated with soda ash (Na2CO3) at various ratios and due to the ion exchange; the original Ca-bentonite was converted to Na-bentonite. It was found that the Na2CO3 activation improves the swelling ...
Intercalation of ionic liquids into bentonite: Swelling and rheological behaviors
(
Elsevier B.V.
, 2016 , Article)
In this study, direct intercalation of three different green ionic liquids (ILs) having different salt and cation sizes into bentonite interlayer is investigated. The ILs covered in this study are: 1-hexyl-3-methylimidazolium ...
Gas solubility and rheological behavior study of betaine and alanine based natural deep eutectic solvents (NADES)
(
Elsevier B.V.
, 2018 , Article)
Natural deep eutectic solvent (NADES) produced herein this work by mixing betaine and alanine with lactic acid and malic acid with 1:1 M mixing ratios. Thermophysical properties including water content, thermal stability, ...
Fabrication of high flux nanofiltration membrane via hydrogen bonding based co-deposition of polydopamine with poly(vinyl alcohol)
(
Elsevier B.V.
, 2018 , Article)
The use of bio-inspired polydopamine (PDA) chemistry for membrane development has attracted increasing interest in recent years. This paper reports on the fabrication of new nanofiltration (NF) membrane with a robust and ...
An empirical determination of the whole-life cost of FO-based open-loop wastewater reclamation technologies
(
Elsevier Ltd
, 2019 , Article)
Over the past 5–10 years it has become apparent that the significant energy benefit provided by forward osmosis (FO) for desalination arises only when direct recovery of the permeate product from the solution used to ...
CO2 Absorption Capacity and its Enthalpy of Absorption in Aqueous Blend of MDEA/Piperazine/Arginine
(
Institute of Physics Publishing
, 2020 , Conference Paper)
In this work, the solubility data of CO2 in aqueous blends of N-Methyldiethanolamine, Piperazine and Arginine (MDEA/PZ/ARG) of a total concentration of two moles is presented. CO2partial pressure was varied from 9 to 99 ...
