Baihuipu Starts Pharmaceutical Oxidation Pilot Line
Baihuipu has started a containerized advanced oxidation pilot line for pharmaceutical wastewater at its Guangdong works. The unit lets clients test ozone, Fenton and UV-based routes on their own refractory streams before committing to a full-scale design. Solvent-bearing and antibiotic-containing effluents are the main target, where biological treatment alone leaves COD and toxicity that a discharge consent will not accept. Pilot reports give measured degradation, reagent consumption and operating cost rather than a modelled estimate.
Key Features and Benefits
Test Your Water, Not a Textbook Stream
Pharmaceutical effluents differ wildly between products and even between production batches. A pilot run on the client's actual worst-case sample settles questions about reagent dose and by-products that no calculation can answer from bulk COD alone. The same selection criteria reappear in Breaking the Refractory Tail, which is worth opening alongside this one.
We set out the wider process route in textile water reuse.
The containerized skid accepts feed drums on site and runs continuous trials with online pH, ORP and COD trend sampling, so the report reflects steady operation instead of a single jar test. If your site also runs this kind of duty, Intermediates Are Molecules With Opinions covers the cost side of the decision in more depth.
Three Routes, One Platform
Ozone contact, Fenton dosing and UV-peroxide loops can be configured on the same skid. Trials compare them on the same feed, which makes the trade-off between capital cost, reagent cost and sludge production visible. The process logic sits close to what is described in Baihuipu Showcases Water Treatment Systems at Industry Expo, particularly on the pretreatment side.
Where oxidation is only a pretreatment, the pilot also checks how much the downstream biological stage improves — often the real justification for the investment.
From Pilot Data to a Design Basis
The output is a written design basis: reagent consumption per cubic metre, sludge production, expected COD reduction and an indicative cost breakdown. That document is what our process engineers use to size a full plant.
What This Looks Like in Practice
One reference point: a 35 m³/day installation we delivered in Fuyang, Anhui (2021) was treating feed at roughly 35,000 mg/L COD and holding discharge near 500 mg/L, about 98.6% removal. The train was pretreatment + Fenton + electrolysis + UASB + A/O.
A second unit of the same class, delivered in Guangzhou, Guangdong during 2022, ran 200 m³/day at 5,000 mg/L feed COD down to 90 mg/L.
| Location | Year | Flow | Feed COD | Treated COD | Removal |
|---|---|---|---|---|---|
| Fuyang, Anhui | 2021 | 35 m³/d | 35,000 mg/L | 500 mg/L | 98.6% |
| Guangzhou, Guangdong | 2022 | 200 m³/d | 5,000 mg/L | 90 mg/L | 98.2% |
Figures are site-measured values from commissioned plants, not modelled estimates.
For streams that respond poorly, the report says so. Declining an unsuitable duty costs less than a full-scale system that never holds its consent.
Technical Specifications
Pilot capabilities versus the typical desktop assessment it replaces:
| Item | Desktop Assessment | Containerized Pilot Line |
|---|---|---|
| Feed used | literature / assumed COD | client worst-case sample |
| Routes compared | one selected up front | ozone / Fenton / UV-peroxide |
| Reagent dose | estimated | measured per m³ |
| Sludge production | not quantified | measured and reported |
| Output | process recommendation | written design basis + cost data |
Why Choose Baihuipu as Your Manufacturer
Picking a supplier for this kind of plant is mostly about who carries the risk when something goes wrong. We have built this equipment for more than twenty years, and we are the ones who fabricated it, programmed the controls and will still answer the phone three years from now.
Own Factory, Real Capacity
Tanks, skids, control panels and membrane housings are built in our own Guangdong facility. Nothing critical is subcontracted, which is why we can commit to delivery dates and hold quality across a batch instead of hoping the shop floor gets it right.
20+ Years Across Dozens of Industries
Experience matters most when your waste stream behaves nothing like the textbook example. We have dealt with toxic organics, heavy metals, extreme salinity and refractory COD in food processing, chemical manufacturing, electroplating, mining and municipal projects.
Complete System Responsibility
One supplier, one process guarantee. We take the plant from preliminary screening through to membrane separation, evaporation and brine management, with process, mechanical, electrical and controls engineering handled internally.
Twenty-Plus Export Markets
We have shipped to the United States, Canada, Russia, Indonesia, India, Nigeria and Vietnam among others. Crating, export documentation and certificates are handled in-house, which keeps customs surprises to a minimum.
After the Handover
Spares for everything we install are held in stock. Remote telemetry is available on most systems, and our service engineers commission, train your operators and turn out for emergencies.
Documentation You Can Actually Audit
Each system ships with as-built drawings, material certificates, welding records and a functional specification. If a client's own consultant wants to review the process calculation basis, we hand it over rather than treating it as proprietary.

Customer FAQs
Why pilot advanced oxidation before building a full plant?
Reagent demand and by-product behaviour depend on the actual molecules in the stream, not on bulk COD. A short trial on the client's own sample prevents an expensive full-scale design built on the wrong assumption.
Which oxidation routes can be tested?
Ozone contact, Fenton dosing and UV-peroxide are all configurable on the same skid, so they can be compared on identical feed with measured reagent and sludge data.
Is oxidation always a pretreatment step?
Often it is. The usual aim is to break refractory compounds into biodegradable ones so a biological stage can finish the job. The pilot measures how much the downstream biology actually improves.
What does the pilot report contain?
COD reduction, reagent consumption, sludge production, operating cost estimates and a written design basis that our engineers use for full-scale sizing. The operating detail behind this sits in EPC wastewater plant.
