New environmentally friendly technology for polishing water
Polishing of water is traditionally carried out in a mixed-bed facility with the use of regeneration chemicals. New technology now allows for totalafsalte water with electric current. This describes the process is termed as electro pure water filter (EDI). Read the original article here
Denmark has the world's best drinking water, but its chemical composition varies pure water filter geographically. This is partly due water flow through the soil layers and their geochemical composition. In addition, the influence of bacteria and biological processes on groundwater quality. The groundwater component includes particles, gases and dissolved salts, each of which helps to give the water its characteristics. For example, the salt content can vary from 250 to 800 grams per salts. cubic meters of water, while the water total hardness is usually in the range of 5 to 30 dH. The water contains more or less undesirable amounts of, inter alia, calcium salts and gases, necessitating a treatment to improve water quality. Refining pure water filter margin depends on the water use, and partly by the demands of the supplier of process equipment.
Water for high-tech processes to be processed water that is used in power stations, universities, hospitals, the pharmaceutical industry and in the electronics pure water filter industry, should have a low content of salts, particles and organic matter. This places great demands on water treatment, where all the unwanted substances must be removed. For some processes, the water must be extremely low conductivity, which in effect makes it electrically insulating.
Demineralization of mains water for many decades, it was necessary to use chemicals generated demineralization plant for the production of desalinated water. Initially the plant of medstrømsregenererede demineralization, which is characterized in that they have to be regenerated with hydrochloric acid (HCl) and sodium hydroxide (NaOH) when the capacity is used. Regeneration requires therefore pure water filter handling and storage of these chemicals, as well as the effluent from the plant must be neutralized before it can be discharged into drains. In an effort to include reducing the consumption of chemicals have been developed counter artificial demineralization and the efficiency of the ion is improved. Today, one can as an alternative pure water filter to chemicals generated demineralization desalinate water in a reverse osmosis (RO) system. In an RO plant desalted water in that it is forced under pressure through a semi-permeable membrane. Membrane retains 98-99% pure water filter of water salinity and 70-99% of the natural organic components. To avoid calcareous deposits on the membranes of the plant must feed water to the RO plant is softened by ion exchange, where its content of calcium and magnesium are exchanged for sodium. Water desalinated in a reverse osmosis system described pure water filter as permeate. pure water filter Whichever method pure water filter is used, it has treated demineralized water typically pure water filter has a conductivity of less than 20 uS / cm. The conductivity pure water filter must be reduced to a minimum, it is necessary to polish the water in a totalafsaltningsanlæg. pure water filter
Totalafsaltning by conventional ion exchange pure water filter in order to achieve the quality of demineralized water the demineralised water shall be polished in a mixed bed system. A conventional mixed bed systems are in principle constructed as a container in which the cation and anion exchangers are mixed in a single container. When the water passage of the ion exchangers, it will alternately encounter a cation and an anion exchanger, thereby making it possible to achieve extremely low salt content. If the facility is stationary, it must be regenerated, respectively. hydrochloric acid and sodium hydroxide at the installation pure water filter site. If there is a need for continuous production of fully demineralised water, pure water filter it is necessary to install a duplexanlæg, ie. a plant where two plants are installed in parallel. Are mixed-bed facility pure water filter servicing generated, executed the necessary regeneration of an external regeneration and avoids the handling pure water filter of chemicals and neutralization of regenerationsvandet.
Totalafsaltning by electro An interesting pure water filter alternative to the traditional mixed-bed facility is a elektrodeioniseringsanlæg. In general it can be described as a mixed-bed which is continuously regenerated without the use of electric hydrochloric acid (HCl) and sodium hydroxide (NaOH). The method has several different names, but are often referred to as EDI, CDI or CEDI. Depending on the plant's construction, water treated pure water filter in the EDI system, achieving a degree of purity of the water conductivity is reduced to 0,055 uS / cm, which corresponds to ultrapure water. In addition, reduced water content (TOC content of total organic carbon), and the bacteria count is reduced. There are two principles for electrodeionization of water. An EDI system may be composed of a number of rectangular compartments which is delimited by cation-and anion membranes. Cation membrane is permeable to cations but retains anions and anionmembranen is permeable to anions, but retain cations. The feed water to the EDI system shall at least
