CCD(Closed-Circuit Desalination) 기술 개발사인 Desalitech사는 인도 구자라트 지역의 농약제조 플랜트에 무방류 방식의 고도 폐수처리시스템을 공급키로 했다. Desalitech사는 인도의 선도적 환경엔지니어링 회사인 VPL Environmental Engineering사와 공동으로 추진한다.
200톤/일 규모의 산업용 폐수를 배출수 처리비용을 절감하며 환경영향을 최소화 하는 목적으로 Desalitech사의 CCD 기술에 의한 RO 처리공정으로 무방류를 실현할 수 있으며 비용 및 에너지 사용량을 50% 이상 절감할 수 있게 된다.
이 플랜트는 연간 6천톤의 다양한 농사용 농약을 생산하고 있으며 이 과정에서 사용된 물이 최종 배출되기 전 적절한 처리를 필요로 하는 많은 양의 폐수가 발생되고 있다.

Desalitech RO wastewater use 'will pay back in 6 months'
Desalitech, developer of the closed-circuit desalination (CCD) system, is to supply a zero liquid discharge (ZLD) advanced wastewater treatment system for a pesticide plant in Gujarat, India.
Desalitech is working for UPL Environmental Engineers Ltd (UPLEEL), one of India's leading environmental engineering construction and project management companies.
The Desalitech system will process 200 m³/d of industrial wastewater as part of a treatment process designed to minimize disposal costs and environmental impact by virtually eliminating liquid waste. Desalitech's CCD reverse osmosis (RO) solution will be a key element in the plant's ZLD system, cutting the costs and energy consumption of downstream components by as much as 50%.
The plant (one of several Gujarat) produces up to 6,000 t/year of various pesticides for agricultural use. The process generates a wastewater effluent stream that requires processing prior to disposal.
"Desalitech's technology provides superior operational efficiency by greatly reducing effluent waste while using less energy than any other RO solution on the market," said Santhosh Nair, managing director of UPLEEL. "It is a smart investment that will pay for itself in 6 months. But beyond obvious cost benefits, Desalitech solutions provide a degree of control and flexibility that we haven't had before."
