“…Otherwise a further post-treatment of the permeate is needed to stabilize pH at a higher level while meeting hardness requirements. When high boron concentrations in the feed water cannot be avoided, specific high boron removal RO membrane elements or ion exchangers should be applied (Taniguchia et al 2004;Glueckstern and Priel 2007). Antiscalants like polyphosphonates are frequently applied to prevent clogging of the membranes and also of the deep well injection facilities.…”

The production of fresh drinking water from brackish groundwater by reverse osmosis (BWRO) is becoming more attractive, even in temperate climates. For successful application of BWRO, the following approach is advocated: (1) select brackish source groundwater with a large volume and a composition that will yield a concentrate (waste water) with low mineral saturation; (2) maintain the feed water salinity at a constant level by pumping several wells with different salinities; (3) keep the permeate-to-concentrate ratio low, to avoid supersaturation in the concentrate; (4) keep the system anoxic (to avoid oxidation reactions) and pressurized (to prevent formation of gas bubbles); and (5) select a confined aquifer for deep well injection where groundwater quality is inferior to the membrane concentrate. This approach is being tested at two BWRO pilot plants in the Netherlands. Research issues are the pumping of a stable brackish source water, the reverse osmosis system performance, membrane fouling, quality changes in the target aquifer as a result of concentrate disposal, and clogging of the injection well. First evaluations of the membrane concentrate indicate that it is crucial to understand the kinetics of mineral precipitation on the membranes, in the injection wells, and in the target aquifer.

Brackish water (BW) desalination is a primary path to relieve the shortage of water. As one of the BW desalination methods, reverse osmosis (RO) technology has advantage for both technology and process procedure. The expounding of this research studied or reviewed recent years, reverse osmosis membrane, energy recovery, new energy and application technology in BW desalination of RO at home and abroad. Wind power and solar energy can be combined with energy recovery device for RO. The research also explains that BW desalination by RO is practical and feasible in some areas in China.

“…There exist several treatment methods that can be used to remove F -and Br -in CS water prior to RO and these include chemical adsorption or precipitation, ion exchange, or by selection of appropriate RO membranes [121,124]. The removal of B in a typical desalination process has been shown to be difficult depending on the treatment technology used [126][127][128]. RO operation has shown that the optimal removal of B is dependent on pH, amount of passes of the water through the RO membrane and the type of commercial membrane used.…”

“…RO operation has shown that the optimal removal of B is dependent on pH, amount of passes of the water through the RO membrane and the type of commercial membrane used. Even though RO is able to remove B, a significant amount of energy is required to undertake this process [126]. Pre-treatment methods for the removal of B prior to CS water being treated by RO may include adsorption or ion exchange.…”

Coal Seam Gas Water Quality and Impacts on Downstream Treatment Technologies

The coal seam gas (CSG) industry in Australia is of significant importance economically, especially in Queensland where a substantial increase in the amount of gas extracted over the past six years has occurred. CSG formation, relation to local geological features, extraction approach and the potential impact/benefits of coal seam (CS) water has been considered by reviewing the location of CSG wells in relation to each other, the depth of the well in relation to the coal seam with which the CSG is associated, and the quality of the CS water compared with the requirements for each beneficial use application. An outline of the limited current legislative requirements on physical and chemical properties of CS water as regulated by the Queensland Government is provided, as well as the current treatment technologies used by the major CSG companies to ensure compliance with these requirements. Water quality from 150 CSG production wells from the Surat Basin, Queensland has been analysed and compared within and between multiple gas fields in a small geographic area prior to any storage, disposal and treatment. Chemical analysis revealed the CS water to have high bicarbonate, high sodium, and low calcium, low magnesium and very low sulfate concentrations. The chemical analysis also confirmed that the pre-treatment concentration levels of specific parameters such as sodium, chloride, total dissolved solids, and sodium adsorption ratio were above that required for use by agricultural and industrial sectors, therefore requiring treatment prior to use. This study has shown that the amount of each type of mineral that comprises coal, such as clay, sulfide ores, oxide ores, quartz and phosphates, may explain the water quality patterns by assessing the mineral content of the associated CS water in relation to the chemical composition of Surat Basin coal
