DESCRIPTION OF THE PROCESS
1.1 REVERSE OSMOSIS RO is the abbreviation for reverse osmosis. The word Osmosis has its origin in the greek language, osmos = pressure, thrust. Osmos is the capability of liquids and liquid soluble substances to permeate a membrane. Osmosis takes place when two solutions of different concentrations are on either side of a membrane. The highest concentrated solution will always attract water from the weaker until the same concentration is attained on both sides of the membrane. This occurs under the condition that the water , and not the dissolved substance, can pass through the membrane. The membrane is permeable for one substance but not the other i.e. semi permeable or partially penetrable. It´s used to separate different substances.
RO involves utilizing osmosis with the help of technology. By raising the pressure of the “contaminated” liquid, the water is forced through a synthetic, semi permeable membrane, which separates the smallest particles, molecules and ions, and only allows clean water to pass. PRESSURE

The membrane is fitted in a pressurized vessel. This construction is referred to as an RO-module or just module .

1.2 FUNCTION Before the water is desalinated in the membrane, the water must be free from chlorine, iron, aluminum, silicic acid, particles, organic and biological contaminants, etc. It´s common that the feed water is pretreated before it passes through the system.

MEMBRANE FOULING
Membran-fouling is a complex phenomenon which involves trapping material in the fibre bundle or on the surface of the membrane inside the RO-module. When a RO-module fouls, the salt concentration of the product water usually increases. The conductivity meter shows higher conductivity. When it has reached an unacceptable level is it time for chemical treatment. The following foulings are the most common:
- Scaling - Metal oxides - Particulate matter - Colloids - Biological matter - Hydrolyse by chlorine
2.1 SCALING Scaling is caused by deposits of minerals. A high concentration of minerals as CaCO and CaSO4 precipitate in the RO-module.

2.3 PARTICULATE FOULING the mechanical filtration of particulate matters which are Particulate plugging is caused by big particles (larger than 20 micron) stucked between the walls of the membrane. To avoid particulate plugging, be sure that right micro cartridge is used and is properly installed. 2.4 COLLOIDAL FOULINGS Colloidal fouling is caused by coagulation of colloids at the membrane surface. Colloids are very small particles usually ranging from 0,3 to 1,0 micron in size. To avoid colloidal fouling do not operate the unit in harbours and water which is polluted. If the unit is intended to be operated in such water, an extended pre-treatment section is required . 2.5 BIOLOGICAL FOULINGS Biological fouling occurs when feed water contains sufficient nutrients, to sustain rapid growth of organisms inside the RO-module. This growth leads to deposition of slimes. To avoid biological fouling, do not operate the unit in water which is strongly contaminated with bacteria. Such as harbour water etc. 2.6 HYDROLYSE BY CHLORINE If the unit is operated with water containing chlorine, water needs a pre-treatment. Use a

CLEANING
3.1 CLEANING AGENTS There are three different agents used for cleaning:
1. MT 10 P3-ultrasil 10 pH 12,5 Useful in removing inorganic scale (e.g. calcium carbonate, calcium sulfate, barium sulfate, strontium sulfate) and metal oxides/hydroxides (e.g. iron, manganese, nickel, copper, zinc), and inorganic-based colloidal material. 2. MT 20 Sulfamic Acid pH 1,2 Useful for removing calcium sulfate scale and to moderate levels of organic foulants of natural origin. 3. MT 5 Biosperse 250 microbiocide Useful in the removal of organic foulants of natural origin and biological material (fungi, mold, slimes and biofilm). 3.2 CLEANING ORDER When performing a cleaning, both low pH and high pH agents are used. The agents are used in the following order:
1. MT 10 P3-ultrasil 10
