A typical reverse osmosis plant is a skid mounted system made up of the following parts.Industrial reverse osmosis feed pump:
It is an imported stainless steel feed pump, takes water from the raw water tank and cools it to industrial reverse osmosis.
Consists of an FRP container with multimedia layers of gravel, quartz and silica sand, removes physical particles such as dust, rust, crack, floats and other impurities up to a particle size of 20 microns.
Consists of a FRP container with a granular activated carbon support which removes organic impurities such as chlorine, chlorides, pesticides, peculiar smell, color or any other chemical present in the water.
The cartridge assembly includes 5 and 1 micron filters to remove additional particles up to 5 and 1 micron for further purification. It contains polypropylene fiber (PPF) and polypropylene thread (PPY) cartridges to block the sediments present in the water.
An online dosing pump doses a specific amount of antibacterial chemical to remove microbiological impurities like viruses and bacteria from water like Pseudomonas, Influenza, E.Coli, Coliforms and etc. water and make sure the water is free of all types of bacteria.
An in-line dosing pump doses a specific amount of anti-scale chemical to prevent the RO membrane from spreading. It increases the service life of the RO membrane and reduces maintenance costs.
The purpose of the high-pressure stainless steel pump (imported) in an industrial reverse osmosis plant is to create pressure and inject pretreated water into the industrial reverse osmosis membrane because the latter is a process pressure-controlled, a pressure of 150 to 200 psi being exerted, however, a high-pressure pump on the water to pass it through the industrial reverse osmosis membrane.
Reverse osmosis is a technique that has been used for water purification for decades, reverse osmosis a varied range of stresses, especially when salt, ionic compositions and dissolved solids have to be removed from the water. ‘water. Reverse osmosis can be used to treat brackish water, tap water and seawater; outlet water can be used for food, industries, boilers, agriculture, bottled water manufacturing and many more applications are where reverse osmosis water can be used. In addition, the industrial reverse osmosis membrane can also be used for wastewater treatment and water recycling. Water treatment using reverse osmosis technology is considered the most economical and efficient process for desalinating water. Industrial reverse osmosis is a suitable method for treating water with salt concentrations of 100 to more than 50,000 mg / liter (ppm).
Reverse osmosis is a water purification technology that uses a partially permeable membrane / filter to remove ions, molecules and larger particles from the water. As a result, impure water is retained on the pressure side of the reverse osmosis membrane and only pure water can pass to the other side. The reverse osmosis membrane removes dissolved salts, lead, mercury, calcium, iron, asbestos, cysts, heavy metals, etc. and brings the TDS of water to less than 20 ppm.
The industrial reverse osmosis membrane is enclosed in a housing approved by the ASME (American Society of Mechanical Engineers), having two types of connection, an input and two exit points, an entry point is for injecting raw water in the membrane and in two other outlet points, one for the permeate (purified water) and others for draining (waste water). The reverse osmosis membrane housing is specially designed to withstand high pressure ranging from 150 psi to 1000 psi.
High pressure concentrate valves are commonly used as system pressure control valves in the reverse osmosis plant. Globe valves use a movable disc cap to gradually open or close the water jet, allowing precise flow control. It is made of stainless steel, a food grade material to control and maintain a balance between the reverse osmosis permeate (purified water) and the drain (wastewater).
Before we understand the TDS counter in the reverse osmosis system, we need to know what is TDS? Total Dissolved Solids (TDS) are the sum of the total charged ions present in water, including salts, minerals and metals. The unit of measurement for TDS is milligrams per liter (mg / L) or parts per million (ppm). The TDS meter is a digital device that measures TDS water levels in the reverse osmosis system. The online TDS meter has been installed “online” on the reverse osmosis control panel that measures the TDS of water passing through the line, which is why it is called the “TDS online meter”. The TDS counter has the capacity to check the TDS from 0 to 10,000 ppm.
Two flow meters have been installed on a reverse osmosis system, one to measure the reverse osmosis permeate flow, the permeate is the outlet of purified water from the reverse osmosis system and the second is to measure the flow sewage, water that has been discharged from the reverse osmosis membrane. The unit of measurement for this flow meter is GPM (gallons per minute) and / or LPH (liters per hour).
The reverse osmosis control panel is intended to control the complete operation of the system, the reverse osmosis containing electrical components such as the magnetic connector, the overload circuit breaker, the power relay, the timer, the LED, the digital counters, on / off switch.
The reverse osmosis monitoring panel is intended to monitor the performance parameters of the reverse osmosis system such as flow rates, permeate TDS, feed line pressure and production water. The monitoring panel shows live performance results from the reverse osmosis system.
