4. Water ChemistryWater is a very stable chemical compound composed of Hydrogen (H) and Oxygen (O) atomsIt is referred to as the universal solvent because it can dissolve more substances than any other liquid.Water is unique as it is the only natural substance that can be found in its three states in nature: Liquid, Solid, and GasWater is rarely found in it’s pure, distilled form. It always contains dissolved salts and minerals from its environment.Water Basics402.08.2022
5. Hydrological CycleWater is a product of its environment, absorbing/ dissolving a part of everything it touches air/water AIR: rainwater will absorb solid matter, gases, odors, other impurities that pollute the airSURFACE: as water percolates through the ground, it filters some impurities absorbed from air, but will dissolve earth’s mineralsWell Water/ Ground WaterLower biological content/ Higher content dissolved elementsExtensive water treatment requiredSurface WaterLower content minerals, salts/ Higher content organics/ bacteriaFiltration/ sanitation requiredWater Basics502.08.2022
6. Properties of Water: pHpH scale indicates whether water is acidic, basic, or neutral. Acidic (H+) 1-6.9, Basic (OH-) 7.1-14pH is affected by chemicals present in water and can be indicative of contaminants in the waterThe neutral point of 7 indicates an equal concentration of free H+ and OH- ionsScale is logarithmic, based on concentration of H+ ionsWater Basics602.08.2022
7. Properties of Water: HardnessWater, as rain, absorbs CO2 from the atmosphereWhen CO2 dissolves in water it can form carbonic acid, a weak acidWhen the carbonic acid comes in contact with limestone in the ground (carbonate), it dissolves in the water producing calcium and magnesium bicarbonatesBicarbonates are known as temporary hardness and are soluble. When heated, the bicarbonates will release CO2 and return to its carbonate state, which is less soluble and results in hardnessWater Basics702.08.2022
8. Properties of Water: ChloridesAnion Cl-, not the same as Chlorine (Cl2).Naturally occurring element, most often found as a component of salt (sodium chloride, NaCl) or in some cases in combination with potassium or calcium.Chlorides can be very corrosive! Some stainless steels, when exposed to high amounts of chlorides, will begin corroding in the form of pits or cracksThe negatively charged chloride ions are able to penetrate the passive oxide layer of stainless steel. Once this happens, the pit formation becomes the anode and the rest of the stainless steel surface becomes a cathode.Water Basics802.08.2022
9. Properties of Water: ConductivityConductivity is a measure of the ability of water to pass an electrical current. Dissolved salts and other inorganic chemicals conduct electrical current.Water Basics902.08.2022ppmµS/cmPure Water (16M)-0.06DI Water-0.1 - 2Distilled Water0.3 – 60.5-10RO Water (DL)0.3 – 100.5-15 RO Water (standard)2 – 203 - 30 "Tap" Water100-600150-1’000 Potable Water9501’500Sea Water28’00056’000Brackish Water50’000100’000

14. Water Treatment Methods14Silt FilterRemoves small earth or clay particles from the waterGenerally use a 3µ or 5µ filterMicron rating is the Average size of the openings between pieces of the filter mediaCarbon FilterActive carbon filter removes chlorine from waterSoftenerDecreases hardness by exchanging Ca and Mg ions with NA ionsWill increase conductivity02.08.2022
15. Reverse OsmosisWater Treatment Methods15When a pressure greater than the osmotic pressure is applied to the concentrated side, solvent will flow from the more concentrated solution into the dilute solution, in the direction opposite to osmosis. 02.08.2022Terminology:Feed water: inlet water to the RO Recovery rate: permeate flow/ feed flow (normally 50-80%)RO pump: pump that circulates water over the membranes at a pressure of 8-14 barSalt rejection rate: percentage which describes the amount of solute retained by the RO membrane (normally 95-99%)
16. Reverse OsmosisWater Treatment Methods16Filtration spectrum: particle filtration, microfiltration, ultrafiltration, nanofiltration, ROSkipping over the steps will clog up your membranesRO systems >300l/h should be fed with softened/ dechlorinated waterSofteningHardness has a large effect on effectiveness of RO membranesRO membranes will last longerDechlorinatingPrevents oxidation of the membraneRO membranes have some chlorine tolerance before noticeable loss of salt rejection occursFirst sign of chlorine attack on RO membrane is loss of membrane flux followed by an increase in membrane flux and salt passage02.08.2022

21. For Scale ManagementAdiabatic SystemsPrevent fouling, scaling, corrosion and media deterioration in the unitPrevent corrosion from carryover of solid contaminants into the unitIsothermal SystemsPrevent scale build up in units that effect performance and require extensive maintenancePrevent scale build up that can be harmful to the internal components of the unit (i.e. tank, heat exchanger, electrodes, elements)Why do we need Water Treatment?2102.08.2022
22. For HygieneBacteria: One celled microorganism found all over, needing nutrients in water to multiplyBiofilm:A layer of bacteria, (inside of reservoir tanks, pipes etc.). Disinfection:Kills most bacteria and virusesChemically: Hydrogen Peroxide, sodium hypo-chloride and UV LightUV Light destroys DNA structure of bacteria, so they cannot multiplyWith Metals: Sanosil (Hydrogen peroxide + Silver)Sterilizing:Kills all bacteria and virusesWhy do we need Water Treatment?2202.08.2022

24. For ApplicationsDust - Avoid mineral dust from humidificationCorrosion - Chloride content causes corrosion if condensation occursHygiene – Water treatment – chemical and non chemical to control hygiene – eg. Removal of ironReduce maintenance on humidifying equipment – replacing nozzles/cylinders etc.Why do we need Water Treatment?2402.08.2022
