A division of the Shenhua Group – China's biggest coal producer – Shenhua Ningxia Coal Industry Co. Ltd., is moving forward with developments for a coal-to-liquid (CTL) fuels conversion project, located in northwest China, a dry, water-stressed region.
The project intends to ensure that Shenhua Ningxia complies with statutory regulations and minimises its overall water footprint.
Shenhua selected Aquatech, a global leader in water purification technology for industrial and infrastructure markets, to design, engineer and supply a Zero Liquid Discharge (ZLD) plant for the project, as well as supervise install and commission the ZLD plant.
Aquatech will provide a fully integrated and automated system that it has developed for the CTX market. This system use state-of-the-art AquaEZ™ technology, consisting of conventional UFRO, HERO™ (high-efficiency reverse osmosis), Unseeded Falling Film evaporators, as well as crystallisers at the back end to achieve complete zero liquid discharge.
It is reported the ZLD plant aims to recycle over 55 million liters/day (2300 m3/hr) of wastewater generated by the 4 million tons per year CTL plant and eliminate all wastewater discharge. The recycled water will be treated to a high-purity level and reused in the process facility.
Aquatech will also supply the post-treatment of the recycled water with an ion exchange process to give high-purity water to be used back in the process.
"As an industry leader in Zero Liquid Discharge, Aquatech was awarded this project based on our extensive experience in achieving consistently higher recoveries from difficult wastewater cost effectively as well as reliably. We have previous experience and strong operating installations in projects under similar conditions in China. This project strengthens our position as a leader in ZLD, especially in this part of the world," commented Tom Tseng, General Manager, Aquatech China.
