GUANGZHOU, China (Oct. 20, 2015) – Aquatech has been awarded a contract to provide a water treatment facility that includes a Zero Liquid Discharge (ZLD) plant for a coal-to-liquid fuels conversion project being developed by Shenhua Ningxia Coal Industry Co. Ltd., a division of Shenhua Group, a coal producer in China. The ZLD plant will recycle more than 55 million liters per day (2300 cubic meters per hour) 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. Shenhua selected Aquatech to design, engineer and supply the integrated water facility and to supervise installation and commissioning. Aquatech will supply a fully integrated and automated system that it has developed for the CTX market. This system uses AquaEZ technology consisting of conventional UFRO, HERO (High Efficiency Reverse Osmosis), Unseeded Falling Film evaporators, followed by crystallizers at the back end to achieve zero liquid discharge. The project will ensure that Shenhua Ningxia complies with statutory regulations and minimizes its overall water footprint, an important consideration since coal conversion requires substantial amounts of water—as much as 10 tons of fresh water for 1 ton of coal-derived fuel according to some estimates. The project is located in northwest China, a dry, water-stressed region. Aquatech provides water purification technology for industrial and infrastructure markets with a focus on desalination, water reuse and zero liquid discharge.
