Recovering and Re-use of Salt by Zero Liquid Discharge (ZLD)

Textile dyeing wastewater is a high-risk pollutant. 1,000 to 3,000 m3 of wastewater is produced after manufacturing 12 to 20 tons of textiles.

Hyrec’s OARO is especially feasible for textile manufacturers because it allows them to use a higher-TDS brine in their manufacturing process. With Hyrec technology, they will not only recover more water but also valuable salts, such as sodium sulfate and sodium chloride for direct use in their dyeing process

Recovering and Re-use of Salt by Zero Liquid Discharge (ZLD)

Coal-to-chemical or Coal to X(CTX) process starts with a coal gasifier, followed by the unit operations necessary to convert the gasified products into alternative fuels and chemicals, such as methanol, ammonia, fertilizers, and olefins.

China is the largest producer and consumer of coal in the world. Coal resources are distributed unevenly in China, concentrated mainly in the water-stressed regions in the north and northwest. Shanxi, Guizhou, Shaanxi, Xinjiang provinces, and Inner Mongolia have 80% of the coal and only 10% of the water resources. ZLD is an ideal solution for these regions and, Chinese government mandated ZLD for all new coal-to-chemical plants.

The latest trend in coal-to-chemical ZLD process is to produce industrial grade salt instead of mixed salts, the disposal of which is a big challenge. Chloride and sulfate are the most common ions in the coal-to-chemical ZLD process, and sodium sulfate and sodium chloride are the major salts acquired. Selling those pure salts as industrial materials will help cover the high cost of ZLD.

Commercial forms of sodium chloride and sodium sulfate has a high economical value. Sodium sulfate can be used in surfactants, detergents, glass manufactures as well as sodium chloride has an application in food and industrial processes, chlor-alkali and soda ash production.

Recovering Metals & Minerals

Mining industry generates large amounts of highly concentrated wastewaters.

Hyrec builds systems to remove and recover metals from contaminated waste streams.

Upstream, Downstream and Onshore Solutions

For every barrel of oil, 3-5 barrels of wastewater are produced. These wastewaters are difficult to treat and create extreme environmental challenges. Handling and disposal costs impact  OPEX and  profitability.

Hyrec’s Forward Osmosis + Osmotically Assisted Reverse Osmosis hybrid application is a feasible solution to the  economic and environmental issues  faced by the Oil & Gas Industry.

Recovering Cooling Tower Blowdown Water

ZLD is used extensively in U.S. power plants to treat and recycle Flue Gas Desulfurization (FGD) wastewater and cooling tower blow-down water.

Hyrec’s integrated membrane system can treat these challenging wastewaters efficiently.
