Osmosis| 6  Osmosis is a natural phenomenon that provides water to all animal and vegetable cells to support life  Water moves from a high concentration of water (less sugar/salt dissolved in it) to a low concentration of water (more salt/sugar dissolved in it) across a semi-permeable membrane  This means that water can cross a selectively permeable membrane from a dilute solution (less dissolved in it) to a concentrated solution (more dissolved in it))

Reverse Osmosis | 8

 RO is a form of filtration using osmosis in reverse  Water passes from a more concentrated solution to a less concentrated solution p this a force or p pressure MUST  To accomplish be applied

 RO is used to remove dissolved solids from water but it can also improve taste, odor & color of water  RO membranes have the capability to remove particles as small as ions i.e. magnesium ions or sodium ions  RO membrane b will ill reject j most compounds d based b d largely l l on size i  Dissolved ions, such as salts, carry an electric charge and will also be rejected by membrane

How does it work ? |

 Feed water flows into RO unit with the force of line pressure

 Water is forced through membrane by cross flow filtration  Cross C fl flow filtration fil i is i most commonly l used d in i RO as it i allows ll membrane to continually clean itself  Membrane then either rejects or repels contaminants  Two exit streams generated: waste & product stream  Waste stream consists of: A concentrate (reject) stream which carries i contaminants i ((compounds d too large l to pass through h h membrane)  Permeate stream consists of: Product water which has been forced through the membrane & is virtually free of TDS

FEED WATER

Main flow of impure water to be treated

PRODUCT WATER

Portion of feed water which passes through membrane as permeate

REJECT WATER:

Portion of feed water which did not pass through membrane; carries impurities to drain

MODULE

Combination of spiral round membrane element & pressure vessel

Spiral Wound Membrane |

Thin Film Composite Membrane (TFC) 

RO membrane is a method of fine filtration but much smaller



Membrane consists of tiny pores which are approximately 0.0005 microns in size



THEREFORE reverse osmosis i membranes b are capable bl off rejecting j ti contaminants t i t as smallll as 0.0001 to 0.00001 microns

RO Membrane | 13

 Membrane is the work work--horse of an reverse osmosis system

 When h choosing h i an RO system you must do d so wisely i l – taking ki iinto account water quality li iis very important membranes:  Three main types of membranes: CTA membrane:: Cellulose acetate/triacetate blend  Provides lowest cost per gallon of water  Resists chlorine but has a lower flow rate limit in applications of high water consumptio TFC membrane:: Thin film/thin layer composite  Can handle high flow, has a high rejection rate & can handle high water consumption  Cannot handle chlorine concentrations; water must be carbon pre pre--filtered

Parameters that affect RO |



Water Temperature: Temperature: RO system ratings are based on 770F/ 250C water temperature



i.e. : RO system rated at 20 GPD (gallons per day) at 340F/10C will only produce 6 GPD



Feed Water Pressure: Pressure: A lack in water pressure (less than 40 PSI) will reduce product p water; this can be helped p with the aid of a booster pump p p



Contaminants in Feed Water: Water: Large particles, iron concentration or high levels of hardness in feed water can cause clogging of the membrane Clogging of the membrane can decrease its life



Microorganisms:: RO membranes can filter out bacteria, depending on the Microorganisms bacteria size, however this may cause fouling of the membrane as bacteria can begin to grow through pores of membrane causing



BACTERIA CREEP – RO systems should not be installed on nonnon-potable water

RO Treated Water RO Treated Water | 18

RO systems will remove up to 97% (depending on parameters) of salts in water bringing it closer to a level of ‘pure pure water water’  The purer the water, the more aggressive it will be with materials it comes in contact with  THEREFORE RO can be slightly corrosive  It’s recommended NEVER to use copper piping on RO water

Ultrafiltration| 23

Does not change the chemistry of water.

•For example to obtain potable water from surface water, which is chemically clean, but contains algea and bacteria, UF can be used.

Same water quality with coagulation / flocculaltion  Removes turbidity •Same UF removes larger organics, colloids, bacteria while allowing most ions and small organics to permeate the porous structure. Larger pore size  Requires much lower differential operating pressure. pressure
