Perfectly coordinated process combinations, such as particle filtration, softening, reverse osmosis, ion exchange, ultrafiltration or electrodeionization (EDI), ensure consistently high water quality. Over and over again. Reverse osmosis - Reverse Osmosis (Reverse Osmosis System) Person with headset icon service Trade fairs & events Sheet of paper with arrow pointing down Downloads Light bulb icon Dslqxw Nowar Exspjut Customer solutions Water treatment based on the model of nature: reverse osmosis The experts at EnviroFALK develop reverse osmosis systems, also known colloquially as reverse osmosis systems or simply RO, which are optimally adapted to the various areas of application. The desalinated water is required for industrial processes as well as for applications in hospitals, laboratories and medical technology. Graphic reverse osmosis How reverse osmosis works – RO Reverse osmosis (reverse osmosis system) is based on the effect of osmosis, which can be seen in nature, for example, in burst cherries after a summer rain. The cherry contains a concentrated solution, the cherry juice. The raindrop represents the diluted solution. The skin of the cherry now equalizes the concentrations. The solvent enters the cherry through the cherry skin, the semi-permeable membrane. The system strives to achieve a balance between the two concentrations. However, as the volume of the cherry cannot increase, the pressure rises. This pressure is the osmotic pressure. In nature, this increase in pressure causes the cherry to burst. If this effect is reversed, the result is a reverse osmosis system. Pressure is exerted on the concentrated solution in order to overcome the osmotic pressure of this solution. The solvent passes through the membrane again and all dissolved water components remain on the concentrate side. Reverse osmosis water filter (Reverse Osmosis – RO) Reverse osmosis (reverse osmosis system), also known as reverse osmosis (RO), is a membrane process that retains ions as well as particulate substances in the water. This reverses the natural process of osmosis. In reverse osmosis systems, the saline solution (e.g. softened city water) is passed under pressure through semi-permeable membranes in the form of winding elements. Only the solvent, i.e. pure water, passes through the membrane and is obtained with a very low salt content as so-called permeate. All water components are concentrated and must be discharged to the sewer with a second partial flow, the concentrate. Reverse osmosis system (RO) On a large scale, a reverse osmosis system (RO) is not operated as dead-end filtration, but as cross-flow filtration. The raw water supply is divided into a pure water – the permeate with a proportion of 75-80% and a residual salt content of approx. 2% – and a concentrate, with which all other water constituents are continuously discharged from the reverse osmosis system. Reverse osmosis is often used in ultrapure water systems for green hydrogen production. It goes without saying that EnviroFALK water treatment systems are tailored precisely to your glass washing machines, the glass to be processed and the glass throughput

Year of construction: 2008, Condition: good (used), For active environmental protection: The ultimate washbasin parts cleaner is in good used condition. The Bio-Circle Washbasin Cleaner, Compact Washbasin, uses an electrically operated pump to pump the cleaning fluid to the 3-way valve. Depending on the position of the 3-way valve, the cleaner can be pumped into the table via the hose with a wash brush, including a work surface storage tray, the articulated hose, or both. Powered by BioCircle L Liquid, the container in the parts washbasin breaks down the cleaning fluid contaminated with oil/grease, for example, using microorganisms. According to the operating instructions, Bio-Chem Surface Technology is used. The used parts and/or brushes for natural, biological parts cleaning have an integrated heater, pump, ventilation, and filter and have been regularly maintained. The magnet in the drain strainer retains steel particles. Fully functional and in good condition. Protect the environment through environmentally friendly cleaning.
