Plants you can name, dated, with the salt they produce
These zero liquid discharge projects each carry a location, a capacity, the by-product recovered and the start year. Where one is still being built, it says so.
What these zero liquid discharge projects show
A reference list is only worth something if it can be checked. Each card gives the plant, the place, the flow, the salt produced and the year it started.
Filter by industry to find the water closest to yours, or by delivery model to see how we were contracted.
This is a selection rather than the full record. JINGYU has delivered more than 140 water treatment projects, 45 of them integrated zero liquid discharge systems.

Frequently asked questions
How many zero liquid discharge projects has JINGYU delivered?
More than 140 water treatment projects in total, including 45 integrated zero liquid discharge systems. Eighteen of those are operated by JINGYU under long-term contracts. The projects listed here are a representative selection, not the full record.
Are these plants actually running?
Each card carries a status. Operating means the plant is in commercial service, with the start year given. In commissioning and Under construction mean exactly that. We would rather show a project honestly than round it up.
Can I see the full data for a project?
Yes. Tell us which project interests you and we will provide a full case study. That covers feed water analysis, process configuration, guarantees and operating results, subject to the client's confidentiality terms.
What contract models are represented here?
EPC, EPC plus operation, EPCM plus operation, process package and equipment supply, BOO and BOT, and standalone O&M. Filter by delivery model to see which project used which.
Which project is closest to my water?
Filter by industry first, then read the feed characteristics on each card. If nothing matches closely, that is normal. Send your analysis and we will name the nearest technical reference.
Are any of these outside China?
The projects listed here are in China, where the hardest industrial water in the world is currently treated at scale. Our International Business Division was established in 2025 to bring the same capability to clients abroad.
