Membrane Brine Concentrator exempli es the "Make in India" enthusiasm that the country has embraced, and addresses the . dire need for a cost-effective solution to the challenging brine .
Brine management systems are imperative for sustainable water supply and for securing valuable resources from desalination plants. The utilization of membrane brine concentrators has recently been focused on because of their high energy and cost efficiencies compared with those of thermal brine concentrators.
The brine concentrator flood box receives heated liquor and provides distribution into the brine concentrator tube bundle. The photo shows severe fouling of the flood box caused by calcium sulphate precipitation. In many designs brine concentrator blowdown is simply an automatic valve that bleeds off a portion of the recirculating liquor.
1.2. Brine concentrator. In most of ZLD plants, the concentration of feed is not high enough to make solid crystals from, so employing a brine concentrator unit would be advantageous for pre-concentration (Reclamation, 2009).Hence, vertical tube falling film evaporators are widely utilized as a single/multi-effect brine concentrator unit (Minton, 1986).
The most common design of a brine concentrator (BC) consists of a falling film evaporator or a vertical tube. However, the usage of plate type evaporators or horizontally placed spray films are also well known. The treatment process of brine in a BC involves the elevation of the feed solution's temperature to its boiling point using a heat ...

BRINE CONCENTRATOR (BC) - Brine concentration refers to the process of partially evaporating water from the waste stream, thereby concentrating the dissolved solids. There are two primary categories of evaporators used in the wastewater treatment industry: thin film and forced circulation. Most brine concentrators in operation are thin film

based brine concentrator. Another interesting application of the membrane-based brine concentrator is in seawater desalination Figure 6: Specific Energy Consumption of Salt Concentration Systems Table: 1 Membrane Brine Concentrator Performance projects. It can produce more water from the reject brine that is being thrown back to the sea.
High Brine Concentrator and Recovery and Zero Liquid Discharge (ZLD), HB-ZLD™ Systems. There is an increasing need for treatment of produced water from shale/oil development, minimizing the environment impact of the existing desalination plant and treatment of highly concentrated salt in industrial wastewater.
Schematic classification of desalination technologies. Reverse osmosis concentrate (ROC) is a brine that causes several environmental impacts associated with discharge into receiving water bodies [19,20].In the literature, the ROC effluent is also known as reject [21,22] since the main objective of the desalination process is to obtain water for human consumption.
Membrane-based brine concentrators are a promising solution for energy-efficient brine management systems. Conventional membrane desalination methods, such as reverse …
Recovered water in a brine concentrator is suitable as cooling tower or scrubber makeup, and can be recycled to other plant processes, including demineralizer feedwater. These wastewater evaporators can be driven by mechanical vapor recompression (MVR) or with live steam depending on the relative costs of electric power and steam.
Another promising technology is the brine evaporative cooler concentrator (BECC), designed to minimize the amount of brine through the evaporative cooling technique principle (Cipollina et al., 2011). BECC is characterized by two functions: cooling down recirculating brine and subsequently concentrating it for adequate disposal.
Veolia Water Technologies has developed specific process designs for CSG water utilizing advanced HPD brine concentrator technology to reduce waste volumes and provide maximum recovery of clean distillate. This process greatly reduces chemical consumption when compared to conventional treatment schemes as well as produces high-quality ...
To achieve ZLD, a brine concentrator is commonly used to extract water up to a high salinity approaching saturation. However, state-of-the-art brine concentrators are energy-intensive thermal evaporators comprising expensive metal alloys and complex maintenance.

The quality steam is then injected into the well. The separated water is then either disposed of via deep-well injection or, if deep well injection is not possible, the separated water may be taken to Zero Liquid Discharge (ZLD) using a brine concentrator and/or a salt crystallizer.
