RO Reverse Osmosis & Water Treatment | Commercial & Industrial



First of all, we understand what industrial reverse osmosis system technology is. Then, we explain type of industrial RO water filtration systems. Hence, you can understand and learn all details reverse osmosis water treatment.

What is reverse osmosis?

Reverse osmosis removes organic and inorganic matters from unfiltered water, or feed water, when pressure forces it through a semipermeable membrane. So, water flows from the more concentrated side (more contaminants) of the RO membrane to the less concentrated side (fewer contaminants) to provide clean drinking water. The fresh water produced is the permeate. The waste water left over is the concentrate accordingly


A semipermeable membrane has small pores so that block contaminants but allow water molecules to flow through. Hence, in inverse osmosis, water becomes more concentrated as it passes through the membrane to obtain equilibrium on both sides. However, Reverse osmosis, blocks contaminants from entering the less concentrated side of the membrane. For example, when pressure is applied to a volume of saltwater during reverse osmosis, the salt is left behind and only clean water flows through.

How does industrial reverse osmosis system work?

Reverse Osmosis is a technology that is used to remove a large majority of contaminants from water by pushing the water under pressure through a semi-permeable membrane. So, when we are talking about industrial reverse osmosis system, we use 8040 size reverse osmosis membrane.


RO membrane sheet has three layers. These are Polyesterbase, Polysulfane Layer and finally Polyamide Layer. And RO membrane producer gives a form to membrane sheet as follows:

Between each membrane sheet, there is feed spacer, it allows water flow and with pressure, water pass through semipermeable membrane. As you see, flow is spiral direction.

Untill now, we explain how reverse osmosis membrane work, now we explain whole system from flow diagram.

First of all, we send dirty water to pretreatment filter tanks by booster pumps (raw water pumps). Filter tanks depend on project can be Sand Filter (Multi-media filter), Carbon Filter, Water Softener.

Pre-treatment for industrial reverse osmosis system

  • Sand Filter: Sand filters or media filters are most efficiently utilized during operations that require the removal of large amounts of suspended solids in water.
  • Carbon Filter: Activated Carbon or Anthracite filtration media is a great filtration material to remove and filter out turbidity and total suspended solids for the purposes of TSS water treatment.
  • Water Softener: Water softener is the process of ion-exchange, water softener systems work in removing magnesium and calcium found in the water by replacing them with sodium ions. We put ion exchange resin in water softener tanks and use brine solution for regeneration of resins.

After Filter tanks, water goes to cartridge filter housing. This filter has PP cartridge filter inside, and responsible to remove any particle to reach membrane.

Finaly, water comes to reverse osmosis membrane and ro membranes remove all bacteria, viruses, minerals and small particles. Hence, you get very pure water.

Types of Reverse Osmosis Water Systems

We offer industrial water purifier to fit all of your water treatment needs. Please choose from below as regards to your water source and flow range below to view our Reverse Osmosis Systems in your size.

For Industrial RO System, you have to define water source. Chunke Reverse Osmosis Systems for Industry has many options.

How much does an industrial reverse osmosis system cost?

There are four main factors that determine the cost of industrial reverse osmosis systems:

  • What is the flow-rate requirements of the system? In other words, how fast will you need to process a given volume of water?
  • What is the chemistry and quality of your influent stream?
  • What is the target level of quality for treated water?
  • What construction materials are required?
  • Answering these questions can help you to pinpoint your needs, and better understand the costs associated with an industrial water treatment system that’s right for your facility.

Flow Rates for Industrial Reverse Osmosis System

Water flow rate, also known as your liter per hour (LPH) or gallons per day (GPD), is the measurement of how many liters of water could potentially come out of your industrial reverse osmosis system.

It is very easy to calculate flow rate of reverse osmosis system for factory. For example, your facilities or factory needs 100m3 treated RO Water. Now we calculate the flow rate of a reverse osmosis machine. 100m3 is equal to 100.000 liters. We assume that you want your industrial reverse osmosis plant to work 10 hours per day. So, 100.000 liters / 10 hours is equal to 10.000 liter per hours. So, your flow rate is 10.000LPH.

Water Qaulity for Industrial Reverse Osmosis Unit

A key factor in the cost of most industrial water treatment systems is the chemistry and content of the stream to be treated. It is important to thoroughly understand the types and concentrations of substances present, as well as any variability in stream makeup. In general, the greater the number of contaminants present, the greater the number of steps in a water treatment train, and the greater the up-front cost. 

Water analysis report shows what kind of organic and inorganic matters in your water. TDS (Total Dissolved Solids) in feed water give us most important parameter. RO units are using semi permeable membranes, choosing which type reverse osmosis ro membrane depends on your feed water quality. Feed water can how low or high concentrated solution. If water quality details are clear, we can provide high purity water with high quality system design.

Target Purity of RO Systems

It is also important to understand the target output you wish to achieve from an industrial water treatment system. If you are investing in a pharmaceutical water treatment system, for example, you are likely aiming to comply with regulatory standards, which can range substantially depending upon your products manufactured. Fully understanding the contaminant thresholds that are acceptable for your production limits can help to ensure that you choose the right technology to meet your needs, without overspending for water quality that exceeds your target range.

large scale reverse osmosis machine

 Commercial reverse osmosis systems or industrial reverse osmosis systems must provide you right and robust target water quality. Food and Beverage industry can use TDS level less than 100ppm, but pharmaceutical applications needs less than 2ppm total dissolved solids. And also, as regards to your filtered water usage, after RO units may need post treatment like Electrodeionization, UV Sterilizer, Ozone Generator or Polishing Filters.

Construction materials for Industrial Reverse Osmosis System

The materials used to construct your water treatment system can have a huge impact on cost. While many industrial applications involve harsh conditions, such as high flow rates, extreme temperatures or pH levels, and/or damaging chemicals, others are less demanding. If this is the case at your facility, you may be able save on up-front costs by using more affordable materials such as PVC piping and FRP tanks, as opposed to more expensive components such as rubber-lined or stainless-steel vessels and/or piping. In many cases, you may also have the flexibility to choose between less-costly manual controls and comparatively more expensive automated PLC panels.

Also, brans are important parameters in industrial reverse osmosis system cost and price.
