Baihuipu Upgrades Integrated MBR Sewage Treatment Unit
Baihuipu has upgraded its integrated MBR sewage treatment unit, the package plant supplied to industrial parks, campuses and remote sites where a conventional civil works project is not practical. Changes focus on aeration control, membrane rack access and energy use rather than headline capacity. The revised unit keeps the same footprint, so existing foundations and pipework can be reused when an older unit is replaced. First deliveries under the new design are going to a food processing park and a logistics campus.
Key Features and Benefits
Aeration That Follows the Load
Dissolved oxygen control now tracks actual inlet load instead of running a fixed blower schedule. On sites with large day-night swings in flow, that removes a surprising amount of wasted electricity and keeps the biology steadier. The same selection criteria reappear in Baihuipu Completes Zero Liquid Discharge Retrofit Project, which is worth opening alongside this one. We set out the wider process route in evaporation crystallization.
Fine-bubble diffusers are arranged so a single rack can be isolated for service without shutting down the whole basin. Operators no longer have to drain the tank to reach a faulty diffuser line. Much of this mirrors the situation set out in sic wafer fab wastewater.
Membrane Racks You Can Actually Reach
The membrane cassette slides out on guide rails with lifting points accessible from the walkway. Cleaning and inspection that previously needed a crew and a crane now takes one operator and a standard hoist. Plants dealing with comparable loads face many of the same trade-offs covered in Biological Treatment of Agrochemical effluent.
Permeate and air scour pipework uses quick-release couplings, which shortens the time the unit is out of service during scheduled cleaning.
What This Looks Like in Practice
One reference point: a 150 m³/day installation we delivered in Ordos, Inner Mongolia (2021) was treating feed at roughly 1,800 mg/L COD and holding discharge near 500 mg/L, about 72.2% removal.
A second unit of the same class, delivered in Panzhihua, Sichuan during 2022, ran 5 m³/day at 1,000 mg/L feed COD down to 500 mg/L.
| Location | Year | Flow | Feed COD | Treated COD | Removal |
|---|---|---|---|---|---|
| Ordos, Inner Mongolia | 2021 | 150 m³/d | 1,800 mg/L | 500 mg/L | 72.2% |
| Panzhihua, Sichuan | 2022 | 5 m³/d | 1,000 mg/L | 500 mg/L | 50% |

Drop-In Replacement on Existing Foundations
The upgraded unit keeps the same overall dimensions, inlet and outlet elevations and electrical interface as the previous generation. A replacement is a lift-out and lift-in job, not a reconstruction.
Where a site needs more capacity later, units can be placed in parallel with a common control system, so expansion does not mean replacing the original plant.
Technical Specifications
Revised design versus the previous generation at the same footprint:
| Item | Previous Unit | Upgraded Unit |
|---|---|---|
| Aeration control | fixed schedule | load-following DO control |
| Diffuser service | drain whole basin | isolate one rack |
| Membrane access | crane + crew | guide rails + one operator |
| Typical unit capacity | 50-500 m³/d | 50-500 m³/d (unchanged) |
| Effluent use | discharge | discharge or reuse polishing feed |
Why Choose Baihuipu as Your Manufacturer
Choosing a manufacturer here comes down to one question: who is still accountable once the commissioning team flies home. Our answer is that we build and programme our own equipment, then stand behind it for the life of the plant.
Manufacturing Base in Guangdong
Owned production lines mean we control tolerances, materials and delivery. Standard modular units and bespoke skids are both built by our own people, so schedule commitments are ours to keep.
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.
Experience Built the Hard Way
Since the early 2000s we have commissioned plants for food and beverage processors, chemical works, electroplaters, textile mills, mines and municipalities. The lessons that stick are scaling, fouling and sludge handling — those inform every design we issue.
We Engineer the Whole Train
Screening, equalisation, biological or chemical treatment, membranes, evaporation, brine handling — the complete line comes from one organisation. Process design, mechanical, electrical and PLC programming sit under the same roof, so there is no gap for finger-pointing at handover.
Spare Parts and After-Sales Support
We carry membranes, pumps, blowers, diffusers and instruments for every system we supply. Remote support through the PLC is standard on most builds, and on-site service covers commissioning, training and urgent callouts.
Certification and Export Practice
CE marking is standard and we work to ISO 9001 procedures. Where a project calls for specific material grades, pressure vessel certification or ATEX-rated equipment, we build to that standard and ship the full documentation pack.

Customer FAQs
What capacity does an integrated MBR unit cover?
Standard units run from about 50 to 500 m³/day, with parallel trains for larger sites. Sizing is based on peak hour flow and the actual load, not just the daily average.
Can MBR effluent be reused?
Yes, with polishing. MBR permeate is a good feed for RO or ultrafiltration when the site wants water for irrigation, cooling make-up or washing. Reuse limits have to be stated up front.
How much operator time does the unit need?
Automatic control covers aeration, permeate pumping and backwash. Routine work is screening removal, membrane cleaning and sample testing — typically one to two hours per shift.
Can an older Baihuipu unit be replaced without new civil works?
That is the point of the revised footprint. Inlet, outlet and electrical interfaces are unchanged, so most replacements reuse the existing foundation and pipework. The operating detail behind this sits in heavy metal recovery.
