Reverse Osmosis (RO) is a process of physical separation of dissolved solids and minerals present in water. This technology uses the principle of osmosis, wherein the mineral concentration of raw water is reduced by applying high pressure through a semi-permeable membrane. Traders and manufacturer of industrial RO plants in visakhapatnam.

Reverse Osmosis (RO) is a widely accepted unit operation for industrial water purification. The water is typically pressured between 150 to 600 psi and pass through either thin film composite or cellulose acetate membranes. Typical RO recoveries are between 70-90%.

The most important factor in treating industrial wastewater with Reverse Osmosis (RO) is the pretreatment that protects the membrane against organic fouling, mineral scaling and chemical degradation. Before reverse osmosis should be considered, a complete cation/anion balance is required and potential foulants must be identified. High BOD and COD levels can also contribute to membrane fouling. A wide range of pretreatment technologies is available.

The effluent discharged to the sewer typically contains between 200 to 10,000 parts per million (ppm) total dissolved solids (TDS) With the proper pretreatment technology followed by RO, this water can be recycled.

Introduction Of “principle Of Reverse Osmosis”

Principle of reverse osmosis system:

Reverse Osmosis (RO) is the process, in which water is pressurized through a semi –permeable membrane. As a result of this, as shown in the below depicted schematic diagram, water will pass through the membrane surface while the dissolved and particulate materials are left behind. When the pressure is applied to the concentrated solution, water is forced through the membrane from the concentrated side to the dilute side. This process is known as“ Reverse Osmosis.”


Principle of reverse osmosis system

The Membrane Based Technology:

The application of Reverse Osmosis to the solution of problems in water treatment requires an understanding of the basic mechanisms involved in the process, the limitations of reverse osmosis and the pre treatment requirements.

Reverse osmosis utilizes the unique properties of a “Imported” semi- permeable membrane to allow fluid to pass while restricting the flow of Dissolved Ionic material. With pressure applied to impure water on one side of such membrane materials, pure water will pass through, leaving most of the impurities behind. The rejection of the dissolved ionic material is a function of both Molecular weight and Ionic charge. For example, we can expect a nominal 90 % rejection of Sodium Chloride, which means that the product water passing through the membrane will have a concentration of salt approximately One-tenth that if the feed water. The rejection of calcium carbonate (Hardness) will be nearly 95%. While most metallic salts will be rejected at a rate of 98% to 99%.

The rejection of non- ionic or organic material is primarily done by mechanical filtration.

What is reverse osmosis System?

The Reverse osmosis System is composed of two major parts, High Pressure pump and the R.O. membranes. The initial purified water production rate is measured at this pressure.

It appears that there are long term benefits to be gained by operating at lower percent water recovery, particularly in reducing maintenance to the systems and minimizing precipitation problems which may arise due to operator error.

It is important to realize that the purified water from a Reverse osmosis system is delivered essentially at Atmospheric pressure, usually to a vented storage tank. In general, It cannot be operated by opening and closing valve in the product water line (unless special pressure relief is provided). The reason for this is that the high pressure in the system drives the water across the membrane. And no flow of water would be possible if the pressure on both sides of the membranes were same. If, for some reason, the product water line is closed, while the system is operating, the pressure would build up. Of course, if the purified water side of the system was strong enough, the pressure would end up the same as the pump pressure, but at that point, no water would flow across the membrane. In reality, the P.V.C. piping on the product water side normally would not tolerate such high pressure.

The membrane is capable of taking 600 psi of “forward pressure”. i.e. from the direction of the supply water side to the purified water side. However, they are susceptible for it’s tolerance limit for “ Back Pressure.” I,e, from the direction of purified water side to the supply water side.” So, one should take care while operating the system.

The Quality of purified water produced by Reverse Osmosis process is roughly a constant percentage of the feed water. For example, if the feed water is entering at 50 ppm , the purified water may be about 1 to 2 ppm. (i.e. 96.00 to 98.00% rejection of dissolved minerals.). For another example, when the feed water is entering at 500 ppm, the purified water would be from 10 to 15 ppm. Usually a Conductivity meter Or TDS meter is used to measure the mineral contents.

WaterMax treatment of the RO product water can further polish the water and make it suitable for all rinses. To design a successful and cost-effective system, Watermax Technologies evaluates each individual application because the pH, oxidizing potential and concentration of soluble salts of the wastewater effluents often exceed the operating limits of the RO systems.

Applications include treatment and recycle of wastewaters generated from metal finishing and plating operations; printed circuit board and semiconductor manufacturing (treatment and recycle of rinsewaters used in electroplating processes); automotive manufacturing (treatment and recycle of water used for cleaning and painting); food and beverage (concentration of wastewater for reuse and reduction of BOD prior to discharge); groundwater and landfill leachate (removal of salts and heavy metals prior to discharge).
