RO Membrane in Bangladesh has successfully implemented by Heron as a trusted brand since 2008. Reverse Osmosis (RO) membrane is an ultra-modern and latest technology for drinking water systems. Generally, in RO membrane available in Bangladesh uses a semi-permeable spiral wounded sheet which pore size 0.0001 micron. This pore is only suitable to pass pure water and other larges molecules such as TDS (Total Dissolved Solid) and impurities rejecting through the waste line.Considering the best RO Membrane in Bangladesh, Heron is the most price competitive along with high-quality elements. Heron does not compromise with quality and it has been always used a top-ranking RO Membrane sheet from Toray Japan or Filmtec USA. After cutting and rolling the membrane. Heron always 100% QC at own laboratories. As a result, it can ensure the highest quality.
Generally, membranes mean we understand reverse osmosis membrane but in practice, there are many series of its. And during the design of the plant if we think best RO Membrane then we have to find out the natures of water then have to select proper series of membranes. In perspective in Bangladesh to develop the proper design of RO Plant and consider best RO membrane in Bangladesh; at first need to know about series of RO Membrane. So that trace out some parameter of raw water those are most essential. Regarding this issue customers are advice to consult to our engineer to get success. However, in below we mention some series of RO Membrane
Tap Water Series Reverse Osmosis (RO) Membrane
Brackish Water Series Reverse Osmosis (RO) Membrane
Sea Water Series Reverse Osmosis (RO) Membrane
Low Pressures Series Reverse Osmosis (RO) Membrane
Extra Low-Pressure Series Reverse Osmosis (RO) Membrane
Sanitary Series Reverse Osmosis (RO) Membrane
Anti-Fouling Reverse Osmosis (RO) Membrane

What is Reverse Osmosis (RO) Membrane?
Reverse Osmosis (RO) Membrane is commonly use for removing solid from water. Develop of pressure driven membrane took place about one hundred years ago. This technology remains in some mystery specially application of desalination of water. Most interesting matter is the process we known as osmosis, it has been continuously happening in the nature and it also happens in human bodies. In 1784 Jean Antonie discovered the osmotic process by studying a pig’s bladder as a membrane. Now a days we got the concept with modernized technology and it is well knowing as Reverse Osmosis Membrane. We also find different kind, different brand as best RO Membrane in Bangladesh. Those RO Membrane from USA, Japan, Russia, Korea and China.
We know that the reverse osmosis membrane is the core component to reverse osmosis system. Nowadays, reverse osmosis technology applies to the production of water purifier, and gradually enters the lives of thousands of households and industry. Then we also face a problem, that is, when the reverse osmosis membrane useing for a long time, it is inevitable that some pollutants will deposit on the surface of the membrane, which will affect the overall performance. Therefore, in order to restore good performance, it is necessary to clean the reverse osmosis membrane. So, what problems do we usually encounter in the process of reverse osmosis membrane cleaning? There are many unique and OEM RO Membrane in Bangladesh available in the market. But cleaning process of all brands RO Membrane almost same.
How to judge whether the reverse osmosis membrane has been polluted?
Under the standard pressure, but the water flow decreases;
In order to reach the standard water flow, have to increase the operating pressure;
The weight of membrane element increases;
The rejection of membrane element changed obviously (increased or decreased)
When the element is taken out of the pressure vessel, the water is poured into the inlet side of the vertical membrane element.
The water cannot flow through the membrane element, only overflows from the end face (indicating that the inlet channel is completely blocked).
What kind of process should select for general water inflow?
The selection of process depends on individual demand and should be determined by its own economy. At present, under many influent conditions, ion exchange process or reverse osmosis process are technically feasible. The higher the salt content is, the more economical the reverse osmosis is. On the contrary, the lower the salt content, the more economical the ion exchange.
Notices of reverse osmosis membrane cleaning
Check the whole cleaning system before cleaning;
The use of any cleaning chemicals should follow the corresponding safety operation procedures;
In the cleaning process, it is necessary to pay attention to the correct switching of the valve, so as not to generate back pressure in RO. Once the back pressure is caused, the reverse osmosis membrane will be irreparably damaged;
Pay attention to each cycle cleaning time during cleaning. Control the PH of the cleaning fluid is about 10.5. When the color of the cleaning liquid is yellow and deep, and a large number of bubbles appear, it indicates that the cleaning effect is very good;
After cleaning, flush the whole system with desalted water.
