The direct contact membrane distillation (DCMD) applied for the concentration of the primary reverse osmosis (PRO) retentate was presented in the paper. All the experiments were carried out using the self-made hydrophobic polyvinylidene fluoride (PVDF) membranes. The DCMD process (permeate flux and

Based on the hypothesis that ionic liquids should show a similar behaviour as surfactants in membrane filtration, this research work analyses the potential of aggregation control to improve the performance of downstream membrane separations, applied to the system 3-octyl-1-methylimidazolium chloride

Membrane processes are more and more used in treating waste water in order to reuse, and then alleviate water scarcity problems. In this pilot test, ultrafiltration (UF) membrane was chosen as the pretreatment of reverse osmosis (RO) for the reuse of the cooling tower blowdown (CTB) of a power plant

Demand for lactic acid is growing, especially, for its use in the production of biodegradable polymer (polylactate). The current method of production and separation of lactic acid is both expensive and unsustainable. This is partly due to the cost and lower efficiency of the current method for separ

In this study wastewater management options were investigated in terms of sustainability for an industry manufacturing 300 tons of energy drinks daily. A two stage management approach covering both in-plant control and end-of-pipe treatment was adopted for the industry under examination. The charact

A thermoeconomic analysis of a cogenerative system with steam bleedings produced starting from the thermal energy recovered in a municipal solid waste thermovalorization plant is presented. The authors assume that the bled steam is used to feed a seawater multi-stage flash (MSF) desalination plant.

Heavy oil was recovered from contaminated sand through capillary suction into exfoliated graphite with different packed densities by using model sands, alumina powders, with different particle sizes. For efficient recovery it was important to have an appropriate combination of average size of sand p

Commercial polymer cation-exchange resins have been investigated for the separation and recovery of Cu(II) and Ag(I) from synthetic solutions. They contain various ionic species after modification of the cation-exchange resin properties by fixation of organic macro-cations under different experiment

Eleven aromatic pesticides were used for a removal study using a 4040 spiral-wound polyamide nanofiltration (NF) membrane. The influences of molecular weight, molecular size (length and width), flux, and recovery were studied. The molecular weights of these pesticides are from 198 Da to 286 Da. Mole
