Reverse Osmosis Membranes
Reverse Osmosis (RO) is a separation technique that is suitable for a wide range of applications, especially when salt and/or dissolved solids need to be removed from a solution. Reverse Osmosis water purifier uses a semi-permeable membrane to separate water from the dissolved salts. Accordingly, RO can be used for seawater and brackish water desalination, to produce both waters for industrial application and drinking water. It can also be applied for the production of ultrapure water (e.g. semiconductor, pharmaceutical industries) and boiler feed water. In addition, RO membrane systems are used for wastewater and water reuse treatments
Reverse osmosis differs from filtration in that the mechanism of fluid flow is by osmosis across a membrane. The predominant removal mechanism in membrane filtration is straining, or size exclusion, where the pores are 0.01 micrometers or larger, so the process can theoretically achieve perfect efficiency regardless of parameters such as the solution's pressure and concentration. Reverse osmosis instead involves solvent diffusion across a membrane that is either nonporous or uses nanofiltration with pores 0.001 micrometers in size. The predominant removal mechanism is from differences in solubility or diffusivity, and the process is dependent on pressure, solute concentration, and other conditions.
India is progressing and is competing with developed countries of today.
Apart from contributing to the rapid growth, our industries are also producing humongous amount of effluents that affect nature.
Which is why the need of wastewater treatment and recycling has now become a priority, out of everything else.Necessity of wastewater treatment plantsTwo of the main sources of contaminated water are sewage and industrial waste.
And to cope up with this rise especially considering limited freshwater resources like, rivers, wells and groundwater; our focus currently needs to be on the solutions to revive freshwater and methods to recycle and reuse water.The increasing level of wastewater, has more adverse effects.
When the wastewater is released untreated, it mixes with the other water sources and contaminates it.
This way, every water source gets polluted.This negligence needs to be eradicated and proper precautions to emit treated wastewater into the environment, should be taken.
The Plate and Tube membrane in wastewater filtration process incorporates Plate and Tube Reverse Osmosis technology.
It is specially designed for difficult and high concentration wastewater treatment with exceptional stability and high performance.
The anatomy of PTRO membrane makes the wastewater treatment highly efficient with its plate and frame structure.The module with multiple circular membrane cushions within the structure of ABS plastic plates forms a sandwich with a permeate carrier passage for the purified water.
The feed flows over each subsequent membrane cushion contained within the hydraulic plate structure and exits the last chamber as concentrate.
The purified water or permeate is collected from each membrane cushion.
Hence there are two final outlets from each individual module – one is recyclable permeate and the other being RO reject or the concentrate.An Efficient Solution by Rochem IndiaThe highly efficient PT Module Membrane Systems by Rochem India addresses several challenges faced in the treatment of wastewater and its conversion to reusable quality water.The advantages of our PT Module Membrane Systems technology has a long list that includes:Simplified & lower pretreatmentAbility to handle higher COD/BOD, SDI, Turbidity streams compared to conventional technologiesConsistent and high recovery ratesHigh reliabilityConsistent high quality permeateHigh pressure Plate and Tube RO designs for further recovery from RO reject concentratesLesser space requirementThe Plate and Tube RO applications are spread wide and successfully over a range of industries:PharmaceuticalChemicalTextileDistilleryTanneryAutomobileFood & BeverageSteel & PowerElectroplatingAgrochemicalSewageLeachateWe offer customized and continuously evolving technology that adapts with the changing needs of the industry and our clientele.
We think that the tap water that we are using on a daily basis at our homes is safe enough on the use.
Have you ever tried to know that whether or not such water is safe on the use?
And when we come to know that the tap water we use at homes carries higher percentage of iron and also contain chlorine and lead like substances, we may start thinking about a water filter.
For days you have not considered using it and now all of sudden you started thinking that getting a water filter for home can be very beneficial for your health, right!Use the best water filtration system:Well, then the time has come to opt for the water filtration systems NZ announced Clive Mulgrew and get the job done.
The water coming from the tap is the city water.
It might have gone though several tests to make sure that the users can get safe and usable water.
