Multi Billion Dollar Zero Liquid Discharge Opportunity in China
The per capita rainfall in China is only 25 percent that of the U.S. Large scale
industrialization has necessitated major expenditures to reduce water use. The
Zero Liquid Discharge (ZLD) concept is now viewed as an attractive solution for
coal-fired power plants, coal-to-chemicals, refineries and other heavy industry.
China does need international technology. Several U.S., Japanese, and European
companies are pursuing this market.
Veolia Water: As part of the Veolia Water group of companies, HPD Veolia Water
Solutions and Technologies has built more than 700 ZLD systems to date. HPD has
85 years of experience in ZLD technology and has in recent years widened its
American base with projects worldwide including a system for a coal-fired power
plant in China.
GE: ZLD systems combine GE membranes and ultra-filtration systems to improve
water recovery efficiency. The company has supplied a number of ZLD systems
around the world. It is also a major supplier of coal-to-chemicals plants in
China. These plants use very large amounts of water. There has been
international environmental pressure to reduce water consumption from
coal-to-chemical projects in China.
Aquatech: The U.S. based company has developed a ZLD technology for shale gas
water, as well as power plants and coal-to-chemicals facilities. Its technology
was chosen for the Yunnan Yuntianhua’s
coal-to-chemical facility located in China's Inner Mongolia province.
The main sources of contaminants are from the raw water reverse osmosis (RO)
plant and the cooling tower blowdown streams. These effluents are first mixed in
an equalization tank before further treatment (Figure 1).
Combined wastewater is rich in contaminants like oil and grease, volatile
organic compounds and has a relatively high Chemical Oxygen Demand (COD) and
Total Dissolved Solids (TDS) of about 16,000 mg/l.
McWong: Mengda New Energy Chemical Co. Ltd contracted with McWong for a
coal-to-chemicals ZLD system. The overall capacity of this project is 13,200
m3/d including water from the project's own wastewater equipment and discharged
wastewater from water pumping stations and desalination stations. McWong
utilized its own patented zero-discharge process package (UF + RO + vibrating
membrane + multi-effect evaporation concentration) technology to achieve zero
discharge and recycle coal chemical industry wastewater.
IDE: The company is involved in desalination but can provide ZLD plants. A
hybrid system has been installed at the Tianjin power plant, 200 km northeast of
Beijing. The plant provides high quality drinking water for the local
population, as well as industrial boiler makeup and process water for the power
plant. The system is powered by waste heat from the power plant, thereby
reducing the net greenhouse gas emission and reducing energy costs.
MHPS: Mitsubishi Hitachi Power Systems has a spray drier which uses the hot flue
gas to dry the power plant sludge. This results in dry disposal instead of ponds
and potential contamination. It is a low cost approach for coal-fired power
plants. There are 1,000 boiler systems in China operating wet flue gas
desulfurization systems. The spray dryer approach can be combined with the use
of treated municipal wastewater as the raw water source. This results in a net
reduction in water contamination rather than just avoidance of additional
contamination.
