2019年2月13日 · Brine, which could be obtained from the waste stream of reverse osmosis (RO) desalination plants, or from industrial plants or salt mining operations, can be processed to yield useful chemicals such as sodium hydroxide (NaOH) or hydrochloric acid (HCl).

2019年1月14日 · But a less chattered-about problem is the effect on the local environment: The primary byproduct of desal is brine, which facilities pump back out to sea. The stuff sinks to the seafloor and...

2019年11月25日 · Brine, also known as concentrate, is the by-product of the desalination process that has an adverse impact on the environment due to its high salinity. Hence, viable and cost-effective brine management systems are needed to reduce environmental pollution.

2019年12月15日 · Desalination brine has high salinity and contains various chemical contaminants and its disposal causes a major concern for desalination around the world. Environmentally friendly and economically feasible methods are essential for sustainable management of desalination brines.

2022年4月25日 · Brine is an unavoidable product of seawater desalination and is commonly disposed of in oceans and seas, where it has negative effects on the surrounding marine environment and its biodiversity due to the resultant increased salinity and temperature, as well as the presence of chemicals.

2019年3月20日 · The vast majority of brine, 124.5 million m 3 /day (87.9%), comes from SW desalination plants. Comparatively, brine production from desalination plants operating with other feedwater types is much smaller, with BW, RW and WW plants producing 10.23 (7.2%), 1.80 (1.3%) and 3.57 (2.5%) million m 3 /day, respectively.

Desalination brine is a concentrated stream that is generated during the desalination process. Brine commonly has high salinity and TDS (total dissolved ions), which contains ions such as Na +, K +, Ca 2+, Mg 2+, Cl −, SO 42−, HCO 3−, PO 43−, and some critical elements.

A by-product of desalination is brine. Brine is a concentrated salt solution (with more than 35 000 mg/1 dissolved solids) that must be disposed of, generally by discharge into deep saline aquifers or surface waters with a higher salt content.

Desalination brine is a by-product liquid stream with higher concentrations of most of the feed’s dissolved solids, some of the pretreatment additives (residual amounts of coagulants, flocculants, and antiscalants), organics, microbial contaminants and any particulates rejected by the RO membranes. 5) What is brine made up from?/

2021年11月23日 · Desalination and industrial plants all around the world generate large amounts of saline wastewater (brine). The discharge of brine from facilities poses a severe environmental threat, while at the same time, the opportunity to recover resources is being lost as discharged brine is rich in valuable metals that could be recovered as salts/minerals.
