Aquatech secures ZLD project for Chinese coal-to-liquids plant

The ZLD plant will recycle over 55 million litres 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 reused in the process facility. Aquatech will design, engineer and supply the integrated water facility, and supervise installation and commissioning.

Aquatech will supply a fully integrated and automated system that it has developed for the CTX market. This system utilizes the company’s AquaEZ technology consisting of conventional UFRO, HERO (High Efficiency Reverse Osmosis), Unseeded Falling Film evaporators, followed by crystallizers at the back end to achieve compete zero liquid discharge. 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.

“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,” said Tom Tseng, general manager, Aquatech China.
