Why do industries need industrial reverse osmosis system?

Global industrial water use and environmental protection face immense pressure, driving continuous efforts to efficiently recycle and reuse industrial water, shifting the focus from water scarcity to water security. Industrial Reverse Osmosis Systems, utilizing mature and advanced technologies and combinations such as reverse osmosis membranes, ultrafiltration, and ion exchange resins, can provide a reliable water source for industrial production.

What is a reverse osmosis system?

Reverse osmosis is the reverse of the natural process of water permeation (typically, water molecules spontaneously pass through a semi-permeable membrane into the concentrated solution). Reverse osmosis technology applies pressure greater than the osmotic pressure to force raw water through a semi-permeable membrane, effectively removing dissolved salts, heavy metal ions, organic matter, bacteria, and other impurities, achieving deep purification.

What is the working principle of industrial reverse osmosis system?

A seagull's crop contains a thin membrane with a precise structure. Seagulls use this membrane to filter seawater into usable freshwater, expelling seawater containing impurities and high salt concentrations. This is the basic principle behind the subsequent reverse osmosis process.

Why do industries need industrial reverse osmosis systems?

(1) Many industries, such as electronics manufacturing, food and beverage, pharmaceuticals, and cosmetics, require water with low ion content and low microbial counts; otherwise, product qualification rates will be significantly reduced.

(2) Scaling is the biggest enemy of industrial equipment. Scaling leads to reduced boiler efficiency and clogged heat exchangers.

(3) Water standards in various industries are rising, requiring RO technology to meet them. For example, process water standards in the beverage and food industries, boiler feedwater standards, and USP/GMP pharmaceutical water standards.

(4) RO removes corrosive ions, reducing equipment repair and downtime losses.

(5) Reusing high-salt wastewater and wastewater containing heavy metals requires RO reverse osmosis to concentrate wastewater, increase water reuse rates, and reduce sewage discharge costs.

Reverse osmosis technology is widely used in wastewater treatment and reuse, zero discharge, and seawater Desalination.

The market for membrane technology applications includes: petrochemicals, steel, power, pharmaceuticals, food and beverage, microelectronics, resource recycling, and residential and commercial water purification.

How to Choose suit Industrial Reverse Osmosis System?

XJY company offers the following series of products and processes for your selection. The choice of these industrial combinations depends primarily on: raw water type and effluent water quality requirements (pure water/ultrapure water/reclaimed water)

(1)Conventional Industrial Reverse Osmosis System

Process Flow: Pretreatment system + First-stage reverse osmosis

raw water → raw water pump → sand filter → carbon filter → security system → high pressure pump → RO system → UV sterilizer → water supply point

Applications: Meets general industrial pure water requirements, food and beverage, food processing, low-end cosmetics, textiles, papermaking, aquaculture, agriculture, and irrigation.

(2)High-Quality Pure Water Process (Higher Requirements)

Source Water: Groundwater with high hardness

Process Flow:

raw water → raw water pump → sand filter → carbon filter → softer filter → security system → high pressure pump → RO system → UV sterilizer → water supply point

Applications: Laboratory water, cosmetic water, precision cleaning, aquaculture and beverage formulation, commercial laundry, car washing, and preparation of shower gels and shampoos.

(3)Two-Stage Reverse Osmosis

Process Flow: First-stage RO + Second-stage RO

raw water → raw water pump →  sand filter → carbon filter → security filter → Primary high pressure pump → Primary membrane → Secondary high pressure pump → Secondary membrane →UV disinfection→  water supply point

Applications: Can remove a higher proportion of dissolved salts, reduce conductivity, and provide pharmaceutical-grade and electronic-grade water. Suitable for semiconductor cleaning, biopharmaceuticals, medical pharmaceuticals, high-end cosmetics preparation, hemodialysis, kidney dialysis, injection preparation, vaccine production chemical preparation, etc.

(4)Second-Stage RO + EDI (ultrapure water process)

Process flow:

raw water → raw water pump →  sand filter → carbon filter → security filter → Primary high pressure pump → Primary membrane → Secondary high pressure pump → Secondary membrane → EDI system →UV disinfection→  water supply point

Applications: Electronic semiconductors (PCB, chips), power plant boiler feedwater

Why did reverse osmosis membranes win?

Why is reverse osmosis superior in a comparison of membrane separation technologies？

Membrane Separation Technologies:

• Microfiltration (MF): 1μm - Removes suspended particulate matter, clay, silt, and algae.
• Ultrafiltration (UF): 100nm - Removes bacteria, viruses, colloids, humic acid, and turbidity.
• Nanofiltration (NF): 10nm - Removes divalent/high-valent salts, hardness, heavy metals, antibiotics, pesticide residues, disinfection byproducts, endocrine disruptors, and color.
• Reverse Osmosis (RO): 1nm - Allows only pure water to pass through. Removes monovalent salts, small molecules, and organic matter.

Reverse osmosis effectively blocks dissolved salts, heavy metals, and microorganisms from the water, resulting in water purity far exceeding other membrane technologies. This is the fundamental reason for its superiority. RO is the only membrane technology that can directly produce freshwater, pure water, and ultrapure water.
