Reverse Osmosis System

Q1: What is reverse osmosis (RO)?

Reverse osmosis is a water purification process that uses a semipermeable membrane to remove dissolved solids, contaminants, and impurities from water by applying pressure to overcome osmotic pressure.

Q2: What Are The Basic Features Of Reverse Osmosis Systems?

Reverse osmosis systems feature semipermeable membranes for contaminant separation under pressure, effective removal of ions, organics, and microbes, pretreatment for membrane protection, high-pressure pumps, real-time monitoring, and modular designs for easy installation/maintenance.

Industrial reverse osmosis systems are highly effective, typically removing 95%-99% of dissolved salts, heavy metals, organics, and microbes, with performance tailored to specific industrial needs (e.g., high-purity water for electronics or pharmaceuticals) when paired with proper pretreatment and maintenance.

  • Broad Contaminant Removal: Efficiently eliminates TDS, bacteria, viruses, pesticides, and colloids, meeting strict purity standards (e.g., <10 ppm TDS for industrial use).
  • Scalability: Adapts to high flow rates (from 100 L/h to thousands of m³/h) for large-scale operations.
  • Cost-Efficiency: Balances high purification performance with long-term operational savings compared to alternatives like distillation.

Q4: What Is The Industrial Reverse Osmosis Water Treatment Process?

The industrial reverse osmosis water treatment process involves pretreatment to remove impurities and protect membranes, followed by high-pressure-driven separation where water molecules pass through RO membranes, and post-treatment to meet industrial standards.

Q5: What Should I Consider Before Buying a Reverse Osmosis System?

Before buying a reverse osmosis system, consider:

  • Feed water quality: Test for contaminants (e.g., hardness, TDS) to determine needed pretreatment.
  • Water demand: Calculate daily/peak flow rate and required purity (e.g., TDS levels).
  • System size: Ensure it fits installation space and scales with future needs.
  • Pretreatment needs: Check if filters/softeners are required to protect membranes.
  • Operating costs: Factor in energy use, replacement parts (membranes, filters), and maintenance.

Seawater: Specialized seawater RO membrane are required, as it need highly boron removal to desalinate high-salinity water.

Ultrapure Water System

Q1: What is an ultrapure water system?

An ultrapure water system produces water with resistivity≥18.2 MΩ·cm and TOC (Total Organic Carbon) <5 ppb by combining advanced technologies like reverse osmosis (RO), electrodeionization (EDI), UV oxidation, and ultrafiltration.

Q2: What is the difference between Ultra-Pure Water and Deionized Water?

Deionized water primarily removes ions (via ion exchange) but may retain organics, microbes, or particles, suited for general lab/industrial use.

Ultra-pure water undergoes advanced processes (RO, EDI, UF) to eliminate nearly all contaminants (ions, organics, microbes, particles) with resistivity up to 18.2 MΩ·cm, ideal for high-purity needs like electronics or pharmaceuticals.

Q3: What are The Main Application Fields of Ultrapure Water Systems?

The main application fields of ultrapure water systems include electronics (semiconductor and chip manufacturing), pharmaceuticals (drug production and medical device cleaning), power generation (boiler feed water), laboratories (analytical testing), photovoltaics (solar cell production), and biotechnology (cell culture and research).

Q5: How Do You Properly Maintain Ultrapure Water Systems?

Proper maintenance of ultrapure water systems involves a combination of regular checks, component upkeep, and purity monitoring to ensure consistent performance.

  • Replace Consumables Timely: Regularly replace pre-filters (sediment, carbon) to prevent debris and organics from damaging RO membranes; swap out RO membranes, DI resin cartridges, and UV lamps according to manufacturer guidelines (typically every 6–12 months, depending on usage) to avoid ion leakage or reduced disinfection efficiency.
  • Monitor and Test Water Quality: Daily check key parameters like resistivity (aiming for ≥18.2 MΩ·cm), TOC levels, and flow rates using built-in meters or external analyzers. Address deviations promptly-sudden drops in resistivity may indicate exhausted resin or membrane fouling.
  • Clean and Sanitize Components: Periodically clean RO membranes with mild detergents to remove scaling or biofilm; sanitize storage tanks, pipes, and distribution loops (using hot water or approved chemicals like hydrogen peroxide) to prevent microbial growth, especially in systems with intermittent use.
  • Inspect System Parts: Check pumps, valves, and fittings for leaks or wear; ensure pressure gauges and sensors are calibrated annually for accurate readings. Lubricate moving parts as recommended to avoid mechanical failure.
  • Document and Schedule Maintenance: Keep detailed records of filter replacements, cleaning dates, and quality test results. Follow a predefined maintenance schedule (weekly checks, monthly deep cleans) tailored to your system’s usage intensity and application demands.

Q6: Are These Systems Warranty Protected?

Our products come with a one-year warranty period (excluding the consumables).

This warranty covers any manufacturing defects in materials or workmanship, including free parts replacement and repair services for issues arising under normal use and proper maintenance. Please note that the warranty does not apply to damages caused by improper installation, unauthorized modifications, misuse, neglect, or external factors such as natural disasters. For warranty claims, kindly contact our customer service team with your purchase proof and product details, and we will assist in resolving the issue promptly.

Q7: How does electrodeionization (EDI) enhance water purity?

EDI combines ion-exchange resins with an electric current to continuously regenerate resins without chemicals, removing boron, silica, and trace ions with ≥99.8% efficiency. Unlike traditional mixed-bed deionization (MBDI), EDI eliminates hazardous chemical handling and reduces waste by 90%.

Q8: What happens if water quality drops below standards?

Our systems include alarms for resistivity, TOC, or microbial spikes, triggering automatic shutdown or bypass to prevent contamination.

Q9: Can ultrapure water be stored long-term?

No. Ultrapure water rapidly absorbs CO₂ and contaminants from the environment, with resistivity dropping to 4 MΩ·cm within 1 hour. For critical applications, use recirculating systems with 0.2μm filters and UV to maintain purity.

Q10: How often do components need replacement?

RO membranes: 1–3 years (depends on feed water quality).

EDI modules: 5–10 years (minimal maintenance) .

UV lamps: Annually to maintain TOC reduction efficacy .

Pre-filters: 1–2 years (depends on feed water quality).
