Effluent carrying high salt content, thermophilic conditions, or compounds that resist easy biodegradation tends to break conventional biological treatment. Our membrane bioreactor plant holds up where those systems struggle, delivering effluent quality gravity settling was never built to reach.
Industrial effluent entering biological treatment commonly runs at BOD 250 to 400 mg/L and COD 500 to 600 mg/L, well above domestic sewage strength, and often carries high salt concentration, elevated temperature, or chemically resistant compounds that a conventional activated sludge process struggles to handle reliably. A membrane bioreactor plant manufacturer building for this segment has to design around that difficulty, not assume mild, predictable effluent. Submerged ultrafiltration membranes retain biomass regardless of how well or poorly it would settle under gravity, which is precisely why MBR performs where challenging, high-strength or difficult-to-treat industrial wastewater causes conventional systems to underperform.
Membrane configuration and scale get matched to your effluent strength, space and maintenance preferences.
Find the Right MBR Configuration for Your Facility
Membrane modules installed directly within the bioreactor tank, offering high surface area in a compact footprint, well suited to facilities prioritizing minimal plot space.
Membrane units installed outside the main bioreactor for easier access and maintenance, suited to facilities where servicing accessibility matters more than absolute footprint minimization.
Engineered specifically for high-salt, thermophilic or chemically challenging effluent, with membrane selection and biological process tuned to withstand conditions that would foul or inhibit a standard configuration.
Incoming industrial effluent is screened and buffered, addressing flow and concentration variability before entering biological treatment.
Aeration supports microbial breakdown of organic load within the bioreactor, operating at higher biomass concentration than settling-limited conventional systems allow.
Mixed liquor passes through ultrafiltration membranes under vacuum, physically retaining biomass and suspended solids while producing high-clarity permeate.
Air scouring, periodic backflush and chemical cleaning cycles manage membrane fouling, particularly important for high-strength or chemically aggressive industrial effluent.
Treated permeate, already meeting stringent clarity standards, routes to compliant discharge or directly into reuse applications depending on your setup.
This system suits industries generating high-strength effluent with organic load significantly above domestic sewage levels, and specifically those dealing with high salt content, elevated process temperatures, or chemically resistant compounds that conventional biological treatment handles poorly. Facilities facing stringent discharge compliance requirements, tighter than typical municipal norms, benefit from MBR's superior effluent clarity as a direct compliance advantage rather than an added cost with no functional payoff. It is also a strong fit for facilities retrofitting an existing ETP that needs more capacity or better output quality without a complete rebuild.
Effluent difficulty is a major cost driver here, high-salt or chemically aggressive wastewater needs more robust membrane selection and fouling control than moderate-strength effluent, adding to both capital and operating cost. Submerged versus external configuration shifts cost and maintenance profile differently, external systems generally offer easier servicing access at a different capital cost structure than submerged installations. Membrane replacement remains an ongoing cost across configurations, one we factor into total lifecycle cost rather than presenting only the upfront figure. We size cost around your actual effluent characterization and discharge target, not a flat industrial rate that assumes uniform effluent difficulty.
Yes, this is specifically where MBR earns its place, high-salt content, elevated temperature and chemically resistant compounds that destabilize conventional activated sludge treatment are conditions MBR is engineered to handle more reliably, since membrane separation does not depend on biomass settling characteristics.
Well-designed and properly maintained MBR systems commonly achieve BOD under 3 mg/L, TSS under 1 mg/L and turbidity under 1 NTU, though actual performance depends on your specific effluent characteristics and system design, which we confirm during the design phase.
Submerged membranes sit directly within the bioreactor tank, offering a more compact footprint. External or sidestream configurations install membranes outside the main tank, generally easier to access for maintenance. The right choice depends on your space constraints and maintenance preferences.
Yes, MBR is commonly used to retrofit existing treatment plants needing more capacity or better effluent clarity, since the membrane stage can often integrate into existing tank infrastructure without requiring a complete rebuild.
Yes, as a membrane bioreactor plant manufacturer, while we build MBR systems across a range of applications, high-strength and chemically challenging industrial effluent is a specific area where we size membrane selection and biological process design around what conventional treatment cannot reliably handle.
