Reverse Osmosis (RO) System Design
Reverse osmosis is one of the most effective technologies for water purification and wastewater reuse. SMRS Infra provides complete process engineering for RO systems — from feed water analysis through to full system documentation.
Precision-Engineered RO Systems for Industrial and Municipal Applications
A reverse osmosis system is only as reliable as its design. Incorrect membrane selection, undersized pre-treatment or miscalculated pressure requirements lead to premature fouling, high operating costs and poor water quality. SMRS Infra approaches every RO project with detailed feed water characterization first — then builds the system design from the membrane array outward, ensuring pre-treatment, pressure, recovery and post-treatment are all engineered as a coherent system.
What We Deliver
Feed Water Characterization & Fouling Analysis
Analysis of feed water chemistry, Silt Density Index (SDI), Langelier Saturation Index (LSI) and fouling potential to inform membrane selection and pre-treatment design.
Membrane Selection & Configuration
Selection of membrane elements, pressure vessels and array configuration (number of stages, passes, elements per vessel) matched to recovery and permeate quality targets.
System Sizing & Pressure Calculations
Full sizing of the RO system including feed pump sizing, inter-stage booster requirements, energy recovery options and operating pressure calculations.
Pre-Treatment Design
Design of pre-treatment train (multimedia filtration, cartridge filtration, antiscalant dosing, softening) to protect membrane life.
Post-Treatment Design
Remineralization, pH correction and disinfection of RO permeate for the intended end use.
Complete Drawing Package
PFD, P&ID and hydraulic drawings for the full RO system from raw feed to final product water.
