TechnologiesThe various technologies used in ELGA equipment are able to remove impurities fromwater down to extremely low levels; some technologies focus on specific contaminantswhile others have a broader spectrum of targets. To achieve the correct water purity fora particular application, in a cost effective manner, technologies must be arranged incombination and their operation optimized.Activated CarbonCarbonMatrixSmall and largeorganic moleculesPores availableto both smalland largemoleculeadsorptionPores availableonly to smallmoleculeadsorbtionContains a maze of tiny pores with sizes ranging from 0.1– 2.9nmand a surface area of about 1000 square meters per gram. The natureof this surface allows adsorption of organic impurities from thewater and catalytic decomposition of free chlorine and, more slowly,chloramines.It is applied in: Pre-treatment cartridges Composite Vent filters Final Purification cartridgesMicroporous Depth FiltersPre-filtration using microporous depth filters, provides an entrapment/adsorption barrier for the removalof large suspended particles and some colloids from the water entering the ELGA purification process.Typically rated at 5 – 10µm and combined with an activated carbon treatment, these filters act to protectsubsequent RO systems from fouling and blockage.Reverse OsmosisFEEDWATERRO MODULEReverse osmosis (RO) is a process where pressure is used to push waterthrough a membrane filter in a cross-flow fashion. RO-membranes areextremely fine filters and reject water contaminants that are less than1nm diameter. Typically 95% of ionic impurity, most organic impurity,and nearly all particulates, bacteria and bio-molecules are removedfrom the permeate water; these are carried out of the RO module in awaste or concentrate water stream.PERMEATECONCENTRATE4www.elgalabwater.com
TechnologiesIon ExchangeIon exchange resins are often used as part of a final treatment step. Single-use purification packstypically use a mixture of ion-exchange resins and other media. When used to deionize water, chargedimpurities are retained on these resins, while H and OH - ions (which combine to form water) arereleased to replace them. This is a highly efficient process and can remove ions to give product-waterresistivity of up to 18.2 MΩ.cm.ElectrodeionizationElectrodeionization (EDI) combines ion-exchange resins and ion-selective membranes, which are usedto move ionic impurities into a waste or concentrate water stream leaving purified product-water. Asimpurities leave via the concentrate water stream, their build-up does not exhaust the resin, and thereforeprolongs resin lifespan. A single EDI unit may operate for many years before a replacement is required.Typically product water resistivity of 10 MΩ.cm is consistently achieved using this process. This technologycan be used as an alternative to single-use purification cartridges.Ultraviolet (UV) LightGlass Quartz HousingWater FlowUV LampTreatment of water with UV-C light is used to photooxidise organic impurities and/or inactivate microorganisms. Photo-oxidation of organic impurities resultsin polar or charged species that can subsequently beremoved by ion-exchange processes. Typically the UVlamp forms part of a ‘polishing’ treatment loop includingion-exchange, through which water is repeatedlycirculated to maintain quality. Water with Total OrganicCarbon (TOC) of 5ppbC and bacteria at 1CFU/ml can beachieved in ELGA products that use this approach.Sub-Micron FiltrationSub-micron filtration, including micro, ultra-micro and ultra filters (30–3000nm) are used as part of a‘polishing’ loop or at the point-of-use. Fine filtration is applied to remove bacteria (live or dead) andbiologically active molecules. These absolute filters have pores smaller than their intended target andcan retain the impurity while allowing water to pass through. Impurities that are removed by sub-micronfiltration, include bacteria, colloids, enzymes, endotoxins and particulates.www.elgalabwater.com5
