In the medical field, water control is not a luxury: it is a critical parameter for safety and regulatory compliance.
Off-spec conductivity or microbiological contamination can invalidate months of research, damage equipment, or put patient lives at risk.
Puribec designs, manufactures, and deploys robust equipment and ultra-pure water loops that eliminate health hazards and ensure the continuity of your clinical processes — from dialysis to central sterilization, as well as research laboratories.

Sectors served
Technical architecture
Swipe to explore
Challenge 01 · ConductivityThe challenge
USP mandates conductivity below 1.3 µS/cm at 25 °C. Any ionic drift compromises reagents and accelerates subsystem degradation.
The Puribec approach
Dual-barrier high-performance reverse osmosis with automated recirculation and flush at every shutdown to prevent fouling.
Challenge 02 · BiofilmsThe challenge
Biofilm adhesion on pipe walls is the most feared infection risk in hemodialysis and reprocessing (MDRU). Micro-roughness and dead zones promote endotoxin buildup.
The Puribec approach
Synergy of ultrafiltration, microfiltration and UV irradiation (germicidal and organic), with sanitary fittings reducing proliferation zones.
Challenge 03 · ScalingThe challenge
Calcium and magnesium precipitate in sterilization autoclaves and thermal disinfectors — scale deposits become physical nests for biofilm colonies.
The Puribec approach
Industrial volumetric duplex/multiplex softeners, smart regeneration exclusively with soft water and countercurrent flow.
Challenge 04 · TraceabilityThe challenge
Accreditation audits require rigorous traceability. Any gap in continuous data can force the shutdown of an entire clinical department.
The Puribec approach
100% third-party certified components, high-end PLCs and complete instrumentation to centralize logging.
Challenge 05 · Environmental responsibilityThe challenge
Municipal discharge is increasingly monitored and billed based on flow and salt load — facilities must reconcile ultra-pure water with responsible effluent management.
The Puribec approach
Adjustable internal recirculation and recycling loops without membrane fouling. Physical ultrafiltration with no chemical additives.
Puribec manages the entire lifecycle of your medical water treatment project, ensuring frictionless integration from the first day of analysis to ongoing after-sales service.
Physicochemical characterization of your raw water to identify potential fouling factors.
Hydraulic calculations and simulations to determine optimal membrane surfaces and flow rates.
CAD technical sheets transferred to consulting engineers for integration into your master specifications.
Skid assembly in our Quebec factories, followed by careful on-site installation.
Nearly 50 years of expertise, a network of over 30 qualified technicians on the road.
Puribec deploys its solutions across the country’s most demanding medical and scientific applications.
Continuous production of sterile, pyrogen-free water meeting Health Canada’s strict conductivity and endotoxin standards.
Continuous supply of softened and demineralized water for steam autoclaves and clinical washer-disinfectors.
Type I, II and III water purification systems per ASTM/CAP/CLSI/LSPQ standards for analyzer supply and reagent preparation.
Design of purified water (PW) treatment loops compliant with USP requirements and Good Manufacturing Practices (GMP).
With nearly 50 years of history and continuous innovation since 1976, Puribec has established itself as a leading name in medical water treatment across eastern Canada. Our head office, proudly based in Rimouski, oversees a branch network also present in Lévis, Sherbrooke and Montreal.
Our pure water treatment chain designers have engineered and delivered highly complex installations for internationally renowned medical and research institutions, including:
MUHC
Research Institute
CHU Sainte-Justine
Héma-Québec
Enfant-Jésus Hospital
CHUM
Integrating a Puribec treatment chain delivers measurable financial and operational benefits over the short, medium and long term.
USP purified water is mainly intended for manufacturing non-sterile pharmaceutical products, equipment cleaning, and as a pretreatment. Its conductivity must be below 1.3 µS/cm at 25 °C. Water for injection (WFI) requires even stricter thresholds, including near-total elimination of bacterial endotoxins (often below 0.25 EU/ml). To reach this grade, Puribec combines double-pass reverse osmosis (Altum or Sirius Series) with continuous submicron ultrafiltration or mixed-bed deionization.
Hospital central sterilization requires a continuous 24/7 supply of softened water to prevent scale buildup in high-thermal-load autoclaves. A traditional electric softener relies on a clock or timer prone to failure, and can interrupt service during nighttime regeneration. KineticoPRO’s CP and Hydrus Series run purely on the kinetic energy of moving water. In Overdrive configuration, one tank stays 100% active while the other regenerates, guaranteeing constant flow with zero risk of electrical failure.
When a conventional reverse osmosis system shuts down, mineral-concentrated water sits against the membranes, causing rapid crystalline precipitation that clogs the pores. The exclusive patented PureRince cycle actively flushes this saturated water at every shutdown by automatically injecting a minimum of 5 housing volumes of treated water at low pressure. This passive flush prevents scaling with no chemical additives, doubles the useful lifespan of your medical-grade membranes, and reduces the frequency and cost of chemical (CIP) cleanings.
Don’t let water management compromise your clinical protocols. Our specialists handle your entire file — from initial analysis to commissioning.
