FAQ

Q1: Why is RO permeate conductivity increasing or water quality declining?

Elevated conductivity and reduced salt rejection are typically caused by membrane aging, damaged interconnector O-ring seals, upstream pretreatment failure, or raw water quality fluctuations. Quick fix: Inspect pressure vessel seals, verify pretreatment performance, run a Clean-In-Place (CIP) cycle, or replace degraded RO membrane elements.

Q2: What causes unstable pump pressure and reduced permeate flow?

Pressure drops and declining permeate production usually stem from clogged security cartridge filters, mineral membrane scaling, or insufficient pump inlet pressure. Quick fix: Replace clogged 5-micron cartridge filters, perform targeted chemical CIP to remove scale, and calibrate high-pressure pump operating parameters.

Q3: What is the typical service life of an RO membrane?

Under standard operating conditions, industrial RO membranes typically last 2 to 3 years. With effective pretreatment (such as UF or multimedia filtration) and routine CIP cleaning, the service life can be extended to 3 to 5 years.

Functional Logic

  • Core Concept — From "Osmosis" to "Reverse Osmosis"
    Natural Osmosis: Water molecules naturally flow from the low-concentration side (fresh water) to the high-concentration side (salt water).
  • Reverse Osmosis (RO): By applying pressure to the high-concentration side, water molecules are forced to flow in the reverse direction.
    · Rejected Impurities: Effectively blocks salts, impurities, heavy metals, bacteria, and viruses.
    · Permeate: Only pure water molecules pass through the membrane.

Process Flow

  • Pre-treatment:
    · Quartz Sand Filter: Removes sediment and suspended solids.
    · Activated Carbon Filter: Removes residual chlorine, odors, and organics. Security Filter: Final fine filtration to protect membranes.
  • RO Desalination:
    · High-Pressure Pump: Overcomes osmotic pressure.
    · RO Membrane: Filters at 10-5μm (0.00001μm) precision.
    Post-treatment (Optional):
    · UV Sterilizer: Further disinfection for water safety.
