Research Abstracts

• A zero discharge process was proposed to recover acid, base and glyphosate. • A cost assessment of the recovery of glyphosate is presented. • Membrane technology is environmentally friendly to treat the glyphosate liquor. A hybrid membrane process composed of NF and RO can be used to treat the gly

• Membranes reduce the energy costs of atmospheric water generation by more than 50%. • We propose a model system to concentrate water vapor with membranes prior to cooling. • A system analysis is performed and ideal operational conditions determined. • A low pressure sweep allows energy efficiency e

Direct contact membrane distillation (DCMD) module was operated with three flat sheet commercial membranes (PTFE/PP 1.0, PTFE/PP 0.45, and PTFE/PE 0.45) under various operating conditions. High flux was observed when the PTFE/PP 1.0 membrane was used and there was no membrane wetting when the feed con

Forward osmosis is a rapidly emerging technology that has potential to enable low cost water treatment and desalination. Previous investigations have found that reverse osmosis (RO) membranes were unsuitable for forward osmosis in part due to their hydrophobic support layers, which inhibit wetting.

At present, mechanical evaporators are being used by the textile and dyeing units in Tirupur, South India, to further concentrate the discharge from Reverse Osmosis (RO) units. A large amount of wood is burnt as fuel, leading to air pollution and destruction of the natural habitat. To circumvent thi

The feasibility of silica removal in RO treatment of groundwater from a Western Australian mining and processing operation to prevent scaling and enhance water recovery was investigated. This study has shown that it is possible to decrease the silica concentration in RO concentrate to levels that wo

Water quality sampling and analysis conducted at four global locations, along the shorelines of the Arabian Sea, the Red Sea, the Mediterranean Sea, and the Caribbean Sea, demonstrated that subsurface intakes (wells) provide a robust degree of feed water treatment close to that provided by energy-in

Like other regions around the world, southern Brazil has experienced periods of drought, having to find alternative water resources for producing drinking water during these times. The deep wells drilled in the Guarani Aquifer could help with this water imbalance, but the water, in some places, is br

• A hydraulic pellet microfiltration process was developed to efficiently remove Sr. • The majority of Sr was transferred to solid phase by a co-precipitation process. • Microfiltration process was essential to separation and decontamination efficiency. • An exponential equation of Sr content versus tim

The comparative study was conducted to investigate the performance and removal efficiencies of PFOS and PFOA in MBR and PAC-MBR. Solid phase extraction (SPE) followed by HPLC coupled with tandem MS (HPLC/MS/MS) was applied to quantitatively identify PFOS and PFOA in aqueous and sludge samples. Remova
