What Nunchi does

Nunchi is a Mexican engineering and construction company specializing in industrial and municipal wastewater treatment, headquartered in Zapopan (with origins in Mazatlán). The company designs and builds custom water treatment systems — anchored by its proprietary Membrane Bioreactor (MBR) technology, which combines microfiltration/ultrafiltration membranes with the activated sludge process and operates at approximately 0.5 bar transmembrane pressure with air-driven membrane cleaning. Nunchi complements its core MBR line with a portfolio of integrated systems: ozone-based Clean-In-Place (CIP) sanitization for food and beverage processors, Techase Volute sludge dewatering, atmospheric evaporators for complex wastewater (leachate, mining, thermoelectric), ultrafiltration/nanofiltration/reverse osmosis membrane trains for fluoride removal and process water, ozone odor control for H2S abatement, and a telemetry layer for remote monitoring. The company installed the world's first industrial MBR plant in 2002 (Pinsa Mazatlán) and has since executed 27+ documented projects across food processing, beverage/spirits, municipal, energy, hospitality, and real estate end markets.

Nunchi's business model is project-based EPC delivery of treatment hardware and systems, with revenue generated through one-off design, procurement, and construction contracts rather than disclosed pricing schedules or recurring software/service fees. Its go-to-market is direct enterprise sales to industrial facility operators and municipal governments, supported by a website portfolio of case studies, downloadable product catalogues, and a contact form for quotation. Customers include major Mexican and multinational enterprises — MARS EFFEM, Femsa, Nestlé, Petrobras, Patron Spirits, La Costeña, Puratos, Pinsa, Sabormex, Citrex, Frexport — as well as municipal clients in Querétaro and federal infrastructure projects such as Tren Maya. Geographic reach spans Mexico (primary), with installed projects in Colombia, Brazil, Chile, and the United States (Arizona). Ownership, funding history, executive team, and revenue figures are not publicly disclosed; no institutional investors, M&A activity, or parent company relationships are documented in the available data.

Core offering

Nunchi designs, constructs, and installs custom industrial and municipal water and wastewater treatment systems, with MBR (Membrane Bioreactor) plants as the core offering, complemented by ozone Clean In Place (CIP) sanitization, Volute sludge dewatering, atmospheric evaporators, UF/NF/RO membrane trains, odor control, and telemetry monitoring. Each project is custom-engineered to the client's water profile, discharge constraints, and capacity requirements, delivered via engineering-procurement-construction contracts across food processing, beverage, pet food, fishing, and municipal utility clients.

Product overview

Nunchi is an industrial water and wastewater treatment company offering a comprehensive portfolio of treatment systems, primarily centered on MBR (Membrane Bioreactor) technology. The core offering consists of MBR treatment modules for industrial and municipal applications, supplemented by specialized add-on systems including Clean In Place (CIP) ozone systems for food/beverage sanitation, atmospheric evaporators, Volute sludge treatment systems, ultrafiltration/nanofiltration/reverse osmosis systems, odor control systems, and telemetry monitoring. The company provides both large-scale industrial plants (such as the first industrial MBR plant worldwide in 2002) and compact treatment solutions for space-constrained installations. All systems are designed with a focus on sustainability, engineering innovation, and cutting-edge technology.

Broad incumbents

• Veolia Water Technologies: Global water and wastewater treatment major offering MBR, UF, and RO systems alongside operations and service contracts. Compares to Nunchi across both industrial and municipal wastewater verticals, with significantly broader geographic reach and balance-sheet capacity.
• Suez Water Technologies & Solutions: Global environmental services and water technology provider delivering engineered systems, membranes, and treatment chemicals. Competes with Nunchi on industrial and municipal MBR/wastewater bids in LATAM and competes with the ozone CIP cleaning proposition in food/beverage.
• Xylem: Global water technology company offering pumps, treatment systems including MBR (Sanitaire brand), and digital water solutions. Direct overlap with Nunchi's MBR-based wastewater treatment offering in both industrial and municipal segments.
• Evoqua Water Technologies: Wastewater treatment and water reuse specialist serving industrial and municipal clients with biological, membrane, and disinfection systems. Now part of Veolia but operates as a recognizable competing brand, comparable to Nunchi across MBR and advanced treatment applications.

Emerging players

• H2O Innovation: North American water treatment systems and specialty chemicals provider delivering membrane systems, UF/RO skids, and treatment chemicals for industrial and municipal clients. Direct overlap with Nunchi's UF/NF/RO and specialty-treatment offerings.
• Toray Membrane (Toray Industries): Manufacturer of UF, NF, RO, and MBR membrane modules supplied to OEMs and EPCs. Comparable to the membrane stack Nunchi integrates (UF/NF/RO) and competes indirectly via the OEMs that may also assemble MBR skids in Nunchi's served geographies.

Regional players

• Grupo Rotoplas: Mexico-headquartered water solutions company providing storage, treatment, and pumping products for residential, commercial, and industrial customers. Comparable as a Mexican-anchored water-treatment business expanding across LATAM, though more decentralized and consumer-oriented.

Direct peers

• Kubota Membrane Europe / Kubota Water & Environment: Pioneer of flat-sheet MBR membrane technology widely used in industrial and small-scale municipal wastewater plants. Directly comparable membrane-based solution to Nunchi's MBR architecture and competing for similar food-processing and small-municipal projects.
• Fluence Corporation: Decentralized and packaged MBR/wastewater treatment provider serving industrial and municipal clients globally, with a strong focus on emerging markets. Direct competitor to Nunchi's containerized MBR systems and prefabricated plant offerings.

Others

• Kuraray / Calgon Carbon: Activated carbon and specialty chemical supplier serving the same municipal and industrial wastewater clients. Not a direct competitor but part of the same water-treatment ecosystem, often specified alongside MBR/ozone systems for polishing steps.
