Custom-Engineered MBR, UF & RO Systems for Global Projects
Rielli manufactures project-specific water and wastewater treatment plants for engineering, EPC, MEP and infrastructure companies worldwide.
From technical evaluation and system selection to in-house manufacturing and after-sales support, we help our partners deliver reliable treatment solutions without developing additional manufacturing resources.
One Stop Manufacturing Partner for Water and Wastewater Treatment
Whether your project requires wastewater reuse, RO pretreatment, desalination or industrial process water production, Rielli develops treatment systems according to the feed water characteristics, required capacity, product water quality and site conditions.
Our MBR, UF and RO plants can be supplied as modular, skid-mounted or fully project-specific systems.
Our Treatment Technologies
Membrane Bioreactor — MBR Plants
Rielli MBR plants combine biological wastewater treatment with ultrafiltration membrane technology to produce high-quality treated water within a compact footprint.
MBR technology is particularly suitable for difficult wastewater, advanced treatment, wastewater recycling and capacity upgrades where additional construction space is limited.
Key Benefits ✅
- High-quality effluent suitable for water reuse
- Compact footprint compared with conventional treatment plants
- Suitable for new facilities and capacity upgrades
- Project-specific and modular plant design
- Reliable biological and membrane treatment in one system
Ultrafiltration — UF Systems
Rielli ultrafiltration plants use membranes with a filtration sensitivity of approximately 0.01 microns to remove suspended solids, turbidity and microorganisms from water.
UF systems are widely used for wastewater recovery, potable water treatment, bottling facilities and as reliable pretreatment for reverse osmosis plants.
Key Benefits ✅
- Effective protection for downstream RO membranes
- Low-pressure and energy-efficient operation
- Suitable for water with high turbidity and suspended solids
- Reliable treatment for water reuse and potable water applications
Reverse Osmosis — RO Plants
Rielli reverse osmosis plants remove dissolved salts and other contaminants by passing pressurized water through high-performance membranes.
Our RO systems are engineered for brackish water, seawater desalination, potable water production, demineralization and industrial process water applications.
Key Benefits ✅
- Brackish water and seawater RO configurations
- Efficient desalination and demineralization
- Optimized investment and operating costs
- Project-specific membrane and equipment selection
- Suitable for potable and industrial process water production
