About us
Engineers who build what they quote.
Waste Water Equipment Factory is the export brand of Shanghai Mars Industrial Co., Ltd. From Shanghai we design, fabricate, test and ship equipment that cleans water, dewaters sludge and turns waste into something manageable.
Who we are
A manufacturer, not a middleman.
Most wastewater projects fail at the interfaces: a screen that passes fibre into a DAF, a clarifier that sends too much sludge to an undersized press. We avoid that by sizing screens, flotation, biology, clarification, disinfection and dewatering as one system — and by building those machines ourselves.
Our customers are plant owners, EPC contractors and distributors who need equipment that arrives on time, matches the drawing and runs on the first start-up. That is why every machine is run before dispatch, and why each buyer receives the test report and an outgoing-inspection video before the container is sealed.
We are equally comfortable shipping one screw press to a dairy or a complete package sewage plant to a resort. If a simpler or cheaper process will meet your limits, we will say so.
Principles
Three rules we work by
Whole-line thinking
Each stage is sized for what the stage before it really delivers, so the line works as a system.
Specification honesty
We quote what we can build and test. Anything beyond the standard specification is confirmed in writing.
Evidence before shipment
Running test, machinery test report and outgoing-inspection video — before you pay the balance.

FAQ
About working with us
Where is Waste Water Equipment Factory based?
Waste Water Equipment Factory is the export brand of Shanghai Mars Industrial Co., Ltd., based in Shanghai, China. We export environmental equipment to buyers worldwide.
Are you a manufacturer or a trading company?
We design, fabricate, assemble and test the equipment we sell, and we handle export packing and documents ourselves, so buyers deal directly with the engineering and production team.
Do you sell single machines or complete systems?
Both. Many buyers order a single dewatering machine or flotation unit; others order a complete line from screening to sludge cake, engineered as one package.
Can I inspect the equipment before shipment?
Yes. You receive a machinery test report and an outgoing-inspection video for every machine, and you or your third-party inspector are welcome to attend the test run in Shanghai.
Which languages do you work in?
Quotations, drawings and manuals are provided in English; our team also works in Chinese.
