SEA & BRACKISH Desaliatio by Sea ad Brackish Water Reverse Osmosis (SWRO ad BWRO) membrae techology is a established optio for the developmet of ew regioal water supplies. Reverse Osmosis (RO) is also a widely accepted techology for idustrial water purificatio. Effective mieral ad salt removal coverts previously uusable water ito a high-purity resource for idustrial process uses.
UNIHA Sea & Brackish Water Desaliatio RO techology is used to remove salt from salty water by usig a semi-permeable membrae. RO ivolves the reversal of flow through a membrae from a high saliity (cocetrate) solutio to the high purity (permeate) stream o the other side of the membrae. As the pressure loss i the membrae module is very low, the high pressure cocetrate flow ca be directed through a eergy recovery device (ERD). Thus a cosiderable amout of the eergy that is otherwise lost ca be recovered. Other desaliatio techologies available iclude evaporatio, membrae distillatio, forward osmosis ad electro dialysis. UNIHA ca help i selectig the appropriate process for all the project-specific circumstaces. Pre-treatmet is essetial to protect the membraes agaist orgaic foulig, mieral scalig ad chemical degradatio, i.e. to miimize chemical cleaig ad membrae replacemet. Depedig o the raw water quality, use is made of covetioal filtratio or ultrafiltratio (UF), dissolved air floatatio (DAF), water softeig or acidificatio ad disifectio. The UNIHA RO systems deliver high performace at the lowest life-cycle costs. Our pre-egieered systems allow fast delivery ad are built with high-quality compoets desiged to meet the customer s specific requiremets. They are assembled at the customer s facilities uder the supervisio of highly qualified UNIHA egieers ad haded over to the customer ready to ru with all filters, membraes, pumps, pipig, cotrols ad automatio. I additio, UNIHA provides a full lie of membrae treatmet chemicals to ehace membrae performace oce equipmet is operatig at your site.

GROUND & SURFACE May groud water sources cotai excess cocetratios of arseic, magaese ad iro as well as ammoia ad methae. Surface water ofte carries particles, biomass, excremetal or idustrial pollutio. All these compoets are potetially harmful; they impair the aesthetic quality of the water or cause operatioal problems.
UNIHA Groud & Surface Water Water Treatmet for Villages ad Cities May atural water resources cotai impurities or pollutio ad caot be used safely without treatmet. UNIHA provides tailor-made solutios to remove these compouds for all system sizes o the muicipal water treatmet market. Our missio is to esure safe ad ecoomic drikig water. Groud ad surface water treatmet icludes the removal of turbidity ad odors, dissolved gases, ad metals, atural ad mamade orgaic matter ad bacteriological cotamiatio. The mai treatmet steps are aeratio ad oxidatio, chemical coditioig, settlig, filtratio ad disifectio. Here, biologically active filters or bio filters ca substatially improve the purificatio efficiecy, or may eve replace chemical treatmet ad save the correspodig operatig costs. The requiremets for treatmet plats differ widely from small to large scale, from remote to urba areas, from low to high tech. The art is to idetify the optimum process for every setup ad to satisfy the local eeds. The UNIHA portfolio ca satisfy all the requiremets; it icludes covetioal techologies as well as advaced cocepts such as membrae filtratio. The latter ca offer sigificat advatages over covetioal water treatmet methods i terms of footprit ad purificatio efficiecy. UNIHA provides special desigs for villages ad small commuities. These systems are desiged for a compact footprit, low civil egieerig requiremets ad easy istallatio. Aother focus is o reliability ad easy operatio with low maiteace requiremets. All further plat compoets - from the itake to the storage tak - ca be icluded accordig to local eeds. FEATURES Chemical-physical-biological water treatmet Covetioal versus membrae filtratio Wells, itakes ad storage taks Tailor-made solutios for local requiremets BENEFITS Safe ad ecoomic drikig water supply Guarateed product quality Adjustmet to local kow-how ad resources Low maiteace ad easy operatio UNIHA 7
INDUSTRIAL & WASTE May idustrial processes deped o the availability of a appropriate water source ad quality. At the other ed, waste water treatmet is eeded to remove or recover costituets that are harmful to dowstream receivers or the eviromet i geeral. The lik is water reuse, which ca substatially improve the ecoomic ad ecological balace of ay water supply scheme.
UNIHA Idustrial & Waste Water Feed-Reuse-Recover-Dispose The retur of ivestmet ad the savig o resources are crucial for every idustrial water treatmet project. UNIHA tailors the optimum treatmet plat accordig to the specific life-cycle requiremets. This icludes the assessmet of reuse ad eergy savig potetial. UNIHA uderstads the importace of esurig the quatity ad the quality of water resources while at the same time cotrollig the evirometal impact of idustrial activities. I partership with the ed user, UNIHA develops a busiess strategy to optimize water ad wastewater treatmet facilities. The mai purpose of waste water treatmet is safe release ito the eviromet. Domestic ad may sorts of idustrial waste water are treated usig a biological purificatio process, while other idustrial wastes require purificatio by physical/chemical treatmet methods. UNIHA provides all the treatmet steps required for compliace with local emissio stadards. This icludes the acillary operatios such as sludge treatmet - from dewaterig to sludge-to-eergy coversio. The cocept of reuse is becomig more ad more commo be it direct reuse or the awareess that a effluet may be the raw water for the productio of drikig water dowstream. While reuse i idustrial applicatios is state-of-the-art, the reuse of domestic waste water is still uder ivestigatio. However, there are examples that show that eve the productio of drikig water from waste water is feasible ad safe. UNIHA helps to exploit the reuse potetial i your applicatio.
