Reverse osmosis - Import export

A saline solution is put in contact with a water permeable membrane (but impermeable to the dissolved solids) at a pressure higher than the osmotic pressure of the solution.

The reverse osmosis is a process of "filtration by means of semipermeable membranes". This process allows starting from salt water to produce pure water, in fact, by exerting a pressure greater than the osmotic cancels the natural tendency that have two solutions at different concentration, in the presence of semi-permeable membrane, the pure water to migrate towards that salt.

The reverse osmosis is a process of "filtration by means of semipermeable membranes". This process allows starting from salt water to produce pure water, in fact, by exerting a pressure greater than the osmotic cancels the natural tendency that have two solutions at different concentration, in the presence of semi-permeable membrane, the pure water to migrate towards that salt. Its main application is the filtration of saline waters, whether of aqueduct or well water, for the production of high quality demineralized water. The reverse osmosis is also applied in the treatment of wastewater for the partial recycling of the same. The reverse osmosis systems are extremely versatile, with modular flow depending on the capacity required. Through "two-stage process", it is also possible to produce ultrapure water. The main application of reverse osmosis is the deionization OF PRIMARY WATERS.

The hyperfiltration plant (commonly known as reverse osmosis) allows the removal of a part of water by a semipermeable membrane and the action of a high pressure. The membrane is made of an organic material (polymer), with thickness of few microns, and supported from another organic material (supporting polymer). For the oenological application of the reverse osmosis, Bared use spiral membranes. Possible application of this plant is product concentration at various percentages: · max sugar recovery (up to 99%) · partial recovery (up to 60%) · concentration of coloured matter · partial or total rejection of acidity and salts.

The essential characteristic of reverse osmosis is not filtration but rather a process by which raw water is seperated into 'pure' water and a concentrate with a high salt content. Permeate is water with above average purity, and is being used for more and more applications. The simple design and ease of automation are further advantages. Modern membranes are characterized by low operating pressures, high yields, and low operating costs.

Recently a new deionization technology, the continuous electro-deionization has been developed, which is a combination of electro-dialysis and ion exchange. It is obtained by a process, which deionized water while the resins are continuously regenerated by means of the electric current inside the unit. This electrochemical regeneration replaces the traditional chemical regeneration of ion exchange systems. The electro-deionization module must be supplied with pre-treated water with reverse osmosis: By combining these two techniques is obtained ultrapure water (0.1-0.2 mS / cm), starting from the drinking water.

High pressure reverse osmosis OSMO Membrane Systems GmbH is excellently grounded in high pressure reverse osmosis systems with a working pressure up to 160 bars (2300 PSI). So, very high salt contents can be reached. Thus, especially for downstream evaporators, the evaporation volume flow can be reduced significantly which means enormous reductions in plant capacity and energy consumption.

Reverse osmosis used for surface water treatment For the retention of dissolved salts and low-molecular Components, nanofiltration or reverse osmosis is suitable. With nanofiltration, multivalent ions and low-molecular components like e.g. humic substances can be retained. Nanofiltration can be used for reduction of hardness, separation of phosphates and sulphates, as well as for reduction of COD and DOC. With reverse osmosis – additionally to the nanofiltration – monovalent ions can be retained. Generally, with reverse osmosis very good retention rates for DOC can be reached, which especially matters at power plant applications.

Rinse water treatment with nanofiltration (NF), reverse osmosis (RO) or electrodialysis (ED) By treatment with nanofiltration, reverse osmosis and electrodialysis, your rinse water can reused a couple of times. By the membrane plant, the pollution of the rinse water is separated and the particles are concentrated. Thereby the water costs and the disposal costs can be minimized. Additionally, materials in the water can be recovered much more easier by concentration.

Condensate polishing During the production process of basic organic chemicals, very often condensates occur as byproducts, which have to be treated before dumping or recycling into production process. The condensate occurring at the product process of caprolactame contents for example ammonium sulfate and caprolactame. The loss of these products instead of recycling would not only mean a reduction of the process recovery, but also very high costs for waste water treatment. These condensates can be concentrated by a reverse osmosis plant. Because of the high salt retention rate of the reverse osmosis membrane, nearly all contents of the condensate are separated and can be brought back to the production cycle. The filtered permeate can be dumped into the municipal waste water system without hesitation. In some cases, the recirculation of the separated contents is not appropriated. In this context, reverse osmosis helps reducing the volume of the accruing condensate. The remaining conden

Brine concentration In many applications of the chemical industries, a concentration by evaporation of mixtures and brines is necessary. Without membrane technologies, the whole volume flow of the process has to be evaporated. With an upstream reverse osmosis plant, the liquid flow can be pre-concentrated and condensed by a factor of 50-75%. The remaining volume flow is treated by a conventional evaporator. The energy consumption of the membrane systems is mostly significantly below of the consumption of the thermal processes, what makes a condensation by membrane plants very economical.
