“…68 For instance, natural zeolite heulandite/clinoptilolite (HEU type) membranes were fabricated and tested for the removal of metal cations and toluene from synthetic seawater at 85 C and 1 atm feed-side pressure under a pervaporative operation. 69 These membranes exhibited rejection rates of 87.4%, 99.9%, 99.4%, and >96% for Na + , Mg + , K + , and toluene, respectively. Water flux was insensitive to toluene over a wide concentration range (10-220 mg L À1 ), but decreased rapidly when cation concentrations in the feed increased.…”

To face the global sustainability issues arising from rapid industry development and population increase, many efforts have been made to develop new materials and technologies toward renewable energy and environmental improvement. Zeolites are a family of crystalline materials with orderly distributed micropores in molecular dimensions. As the most important solid catalysts used in traditional petrochemical industries, zeolites are also finding promising applications in many sustainable processes given their unique shape selectivity, adsorption and ion-exchange capability, high hydrothermal stability, tunable acidity and polarity, and low production costs. In this review, we present the state-of-the-art applications of zeolites as potential solutions to the sustainability issues, including biomass conversion, fuel cells, thermal energy storage, CO 2 capture and conversion, air-pollution remediation, and water purification, etc.

“…However, the addition of some particles, such as clay, can cause the ber diameter to increase. [73][74][75][76][77][78][79][80][81][82][83][84] The performance and some properties of such membranes are shown on the Table 1. MD membranes are constructed using two or three tiers of hydrophobic-hydrophilic membrane layers, unlike in the single unsupported hydrophobic-layer design.…”

“…The potential technologies for oilfield-produced water treatment can be classified into five main groups [7][8][9]: Among these processes, adsorption (by activated carbon, zeolites, clays, resins, and synthetic polymers) [10][11][12], oxidation (chemical, photocatalytic, and sonochemical) [12][13][14], biological treatment [15][16][17], and membrane processes [18][19][20] represent emerging technologies in Canada's oil sands industry. Adsorption processes are used for the removal of a broad range of compounds in oilfield-produced water, including DOM, oil, and heavy metals [21].…”

This chapter summarizes nanofiltration (NF) studies focused on the treatment of thermal in-situ steam-assisted gravity drainage (SAGD)-produced water streams in the Alberta, Canada, oil sands industry. SAGD processes use recycled produced water to generate steam, which is injected into oil-bearing formations to enhance oil recovery. NF has potential applications in the produced water recycling treatment process for water softening, dissolved organic matter removal, and partial desalination, to improve recycle rates, reduce make-up water consumption, and provide an alternative to desalination technologies (thermal evaporation and reverse osmosis). The aim of this study was to provide proofof-concept for NF treatment of the following produced water streams in the SAGD operation: warm lime softener (WLS) inlet water, boiler feed water (BFW), and boiler blowdown (BBD) water. Commercial NF membranes enabled removal of up to 98% of the total dissolved solids (TDS), total organic carbon (TOC), and dissolved silica, which is significant compared to the removal achieved using conventional SAGD-produced water treatment processes. More than 99% removal of divalent ions was achieved using tight NF membranes, highlighting the potential of NF softening for oil sands-produced water streams. The NF process configurations studied provide feasible process arrangements suitable for integration into existing and future oil sands and other produced water treatment schemes.
