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.

Gas, Shale and Refining Markets and Projects
