As environmental regulations continue to tighten worldwide, coal-fired power plants are placing greater emphasis on improving the efficiency and sustainability of flue gas desulfurization (FGD) systems. While much attention is given to the desulfurization process itself, efficient gypsum dewatering is equally critical for maintaining stable plant operation, reducing operating costs, and maximizing water recovery.
At Wuxi Tongzhiren Machinery & Equipment Manufacturing Co., Ltd., we have focused on developing high-efficiency vacuum synthetic-disc filtration technology specifically for FGD gypsum applications. Through years of engineering development and practical field experience, our systems have been successfully deployed across numerous coal-fired power plants throughout China.
Some representative projects include:
▪Inner Mongolia Huineng Changtan Power Plant
▪China Energy Guangdong Taishan Power Plant
▪Henan Nanyang Zhongyuan Chemical
▪Heilongjiang Daqing Power Plant
▪Hubei Energy Jingzhou Jiangling Power Plant
▪Shandong Dongying Shengli Oilfield retrofit project
Compared with conventional belt filter systems, synthetic disc filtration provides several operational advantages:
−75%
Reduction in electrical power consumption
−80%
Reduction in water usage
≈30%
Equipment footprint of a comparable belt filter installation
≈30%
Typical maintenance expenditure vs. traditional belt filters
These improvements help operators lower lifecycle costs while maintaining reliable, continuous gypsum dewatering performance.
As power producers continue investing in cleaner and more efficient operations, optimized dewatering technology remains an important contributor to overall plant performance. Reliable filtration not only improves gypsum handling but also supports water conservation and long-term operational stability.
We remain committed to providing practical, efficient filtration solutions for both new installations and retrofit projects worldwide.
