Pre-Filtration:Thewaterfirstpassesthroughapre-filter,whichremoveslargerparticlessuch assediment,debris,and chlorine.ThisstephelpsprotecttheROmembraneandenhancesitslifespan. Pressure Pump: The water then enters a pressurization chamber where a high-pressure pump is used to exert force on the watermolecules.Thispressureisnecessarytoovercomethenaturalosmoticpressureanddrivethewaterthroughthesemi- permeablemembrane. Semi-Permeable Membrane:The heart of the RO system is the semi-permeable membrane. It consists of tiny pores thatallowwatermoleculestopassthroughwhileblockinglargermoleculesandcontaminants.Asthepressurizedwater passesthroughthemembrane,impurities,suchas dissolvedsalts,heavymetals,bacteria,viruses,andotherpollutants, are leftbehind.

6. ULTRAFILTRATION (UF)SYSTEMS Ultrafiltration(UF)Systemsareadvancedwaterpurificationsystemsthatutilizeaspecialized membrane to filter out contaminants and impurities from water. Unlike Reverse Osmosis systems,UFmembraneshavelargerporesizes,allowingwaterandcertainmoleculestopass throughwhileretainingparticles,bacteria,viruses,andlargerimpurities. Inbrief,theworkingprocessofUltrafiltrationsystemsinvolves: Filtration:WaterisforcedthroughtheUFmembraneunderpressure,wherethe membrane acts as a physical barrier, capturing and holding back particles, microorganisms, and largermolecules. Selective Permeability: The UF membrane has precise pore sizes, typically ranging from0.01to0.1micrometers.Thisallowswaterandsmallersolutestopassthrough, whileblockingsuspendedsolids,colloids,bacteria,andlargercontaminants. HighFiltrationEfficiency:Ultrafiltrationsystemsefficientlyremoveawiderangeof impurities, including turbidity, suspended solids, pathogens, viruses, bacteria, and somemacromolecules.Thefilteredwater,knownaspermeate,iscollectedforuse. MinimalPressureRequirements:UnlikeReverseOsmosissystems,UFsystems operateatlowerpressures,reducingenergyconsumptionandoperationalcosts. Application Diversity: UF systems find applications in various industries, such as foodandbeverage,pharmaceuticals,biotechnology,andwastewatertreatment.They are especially useful in situations where the removal of bacteria and viruses is a priority.

8. UV WATER PURIFICATIONSYSTEMS UVWaterPurificationSystemsutilizeultraviolet(UV)lighttechnologytoeffectivelydisinfectwaterandeliminateharmfulmicroorganisms. These systems work by exposing water to a specific wavelength of UV light, typically around 254 nanometers, which is lethal to bacteria, viruses,andotherpathogens.Theprocessinvolvesthefollowingsteps: UVLamp:ThekeycomponentofaUVWater Purification System is a UV lamp or bulb. This lampemitsUV-Clight,whichhasgermicidalpropertiesandiscapableofdamagingtheDNAor RNA ofmicroorganisms. Water Flow:The water to be treated passes through a chamber or housing where the UV lampisinstalled.ThewaterflowiscarefullycontrolledtoensuremaximumexposuretotheUV light. UVExposure:Aswaterflowsthroughthechamber,itcomesindirectcontactwiththeUVlight emitted by the lamp. The microorganisms present in the water absorb the UV light, which disrupts their DNA or RNA structure, preventing them from reproducing and rendering them unabletocauseinfectionsordiseases. Inactivation of Microorganisms:The UV light effectively inactivates a wide range of microorganisms,includingbacteria,viruses,protozoa,andmolds.Ittargetspathogensthatare commonlyfoundinwater,suchas E.coli,Salmonella,Cryptosporidium,andGiardia. Chemical-Free Process:UV Water Purification Systems provide a chemical-free method of disinfection.Unliketraditionalwatertreatmentmethodsthatmayrequiretheuseofchemicals like chlorine, UV systems rely solely on the power of UV light to neutralize microorganisms, ensuringthatnoharmfuldisinfectionby-productsareintroducedintothewater. ResidualEffects:UVpurificationdoesnotleaveanyresidualtaste,odor,orchemicalresidue in the treated water. It solely eliminates microorganisms, making the water safe and maintaining its naturalcharacteristics.

9. OZONE WATER TREATMENTSYSTEMS Ozone water treatment systems utilize ozone, a powerful oxidizing agent, to disinfect and purify water. Ozone (O3) is a naturallyoccurringgascomposedofthreeoxygenatoms.Itisgeneratedon-siteandintroducedintothewatertodestroy bacteria, viruses, and otherorganic contaminants.

Oxidation Process: Ozone acts as a powerful oxidizing agent, breaking down organic compounds, destroying microorganisms, and removing odors and tastes. It oxidizes and decomposesvariouscontaminants,includingbacteria,viruses,algae,andorganicmatter. ResidualDecay:Afterthetreatmentprocess,anyexcessozonethatremainsinthewater will naturally decay back into oxygen. This decay leaves no harmful by-products, making ozoneasafeandeco-friendlywatertreatmentoption.
