아쿠아테크(Aquatech)는 중국 석탄액화(CTL) 보전 프로젝트에 폐수무방류(zero liquid discharge, ZLD) 수처리를 공급하는 계약을 체결했다. 이번 ZLD 플랜트는 중국에서 가장 큰 석탄 제조업체인 셍화(Shenhua) 그룹의 셍화 닝샤 석탄 산업부(Shenhua Ningxia Coal Industry)가 개발 중에 있는 CTL 플랜트로부터 하루 55ML가 넘는 용량의 폐수를 재활용할 예정이다. 재활용수는 고 순도로 처리되며, 시설 공정에 재사용된다.

Shenhua는 이번 프로젝트의 설계·엔지니어링·시설공급·설치 및 운영 감독업체로 아쿠아테크를 선정했다.

 

 

 

Industrial and infrastructure water purification technology firm, Aquatech, has won a contract to provide water treatment with zero liquid discharge (ZLD) for a coal to liquid fuels (CTL) conversion project in China.

 

The ZLD plant will recycle wastewater at more than 55 Ml/d discharged from a 4 Mt a year CTL plant being developed by Shenhua Ningxia Coal Industry, a division of China's biggest coal producer, Shenhua Group.

 

The recycled water will be treated to a high purity and reused in the process facility. Shenhua chose Aquatech to design, engineer, and supply the facility, and to supervise its installation and commissioning.

Aquatech will supply an integrated and automated system that it has developed for the coal conversion market. This system utilizes state-of-the-art AquaEZ technology comprising conventional ultrafiltration reverse osmosis, high efficiency reverse osmosis, unseeded falling film evaporators, followed by crystallizers at the back end to achieve compete ZLD. Aquatech will also supply post-treatment for the recycled water to feed high-purity water to the process.

 

General manager at Aquatech China, Tom Tseng, said Aquatech was awarded the deal on the basis of its track record of consistent high recoveries from difficult wastewater. "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," he said .
