Key Components of an Industrial RO Plant
- Pre-treatment system: Multi-media filter, activated carbon filter, and water softener to protect membranes
- High-pressure pump: Industrial pumps rated for continuous duty at 150-1000 psi
- RO membrane array: Multiple commercial membranes in series/parallel configuration
- Post-treatment: UV sterilization, re-mineralization, pH adjustment
- Control panel: PLC control with flow meters, pressure gauges, conductivity monitors, and alarm systems
- Storage: SS or food-grade HDPE storage tanks with distribution pumps
Regulatory Compliance for Industrial Water India
- Food and Beverage: FSSAI requires IS 10500 standard water for food processing
- Pharmaceuticals: Schedule M Drugs Act standards for purified water and WFI
- Hospitals: NABH accreditation requires BIS standard potable water
- Dialysis: AAMI standards for dialysis-grade water with near-zero TDS
FAQs
How long does industrial RO plant installation take?
A standard 100-500 LPH system takes 3-7 days for full installation including pre-treatment, RO unit, storage tanks, and commissioning. Larger systems (1000+ LPH) may require 2-4 weeks depending on site preparation. Alkin provides a detailed installation timeline during the free site assessment visit.
What is the lifespan of an industrial RO membrane?
Industrial RO membranes typically last 3-5 years with proper pre-treatment and maintenance. Key factors include feed water TDS, pre-treatment effectiveness, regular cleaning cycles, and operating pressure management. Alkin industrial systems include automated CIP (Clean-In-Place) capability and membrane performance monitoring to maximise lifespan.
Can Alkin manage reject water from industrial RO systems?
Yes. Alkin provides zero-liquid-discharge (ZLD) consulting and can design systems where reject water is further treated for reuse or safely discharged in compliance with CPCB and SPCB norms. Recovery systems for non-potable applications (cooling towers, toilet flushing, landscaping) are available to minimise waste.
