Sand Filter


It is used to remove all colloids and this is mean separating water from all traces and solid materials with different sized atoms and this is happened by using filters with different sized diameters followed by backwash to remove all these materials when filter is saturated

 

 

 

 

Activated carbon filter

It is a kind of water treatment equipment that uses activated carbon in water purification, activated carbon core installed in stainless steel core can absorb all traces intercepted in water and make them solve in water and also eliminating all chemical and dangerous organic matters in the presence of chloride (Cl) ions in water which can protect filter from any damage and removing water taste and smell and improving water quality.
In advanced treating systems , carbon filter can remove the remaining chloride ions that are not removed during the former filtering processes to protect RO membrane , besides it can absorb even small organic and contaminated particles escaped from former filtering beside eliminating colloids , coloring and metal traces ions in water.
Water Hardness Removal (Softener)

It is a device to remove resins from water by using (NaCl) solution

Reverse Osmosis(RO)
It is a technique in which solvent is passing through semi permeable membrane to the solution .
This technique is used in sea water sweeting as we can reduce the salinity of water and also eliminate all harmful organic matters .it is also used in all industries and stations requiring specific solved salts rates.
Reverse osmosis depends on osmosis property , we use osmotic pressure carried out b membranes to overcome water pressure , as theory says if we put a membrane between two equal concentration , temperature , pressure solutions no water passes but if we add some solved salts to any of the solutions the pressure goes down and water passes from the less salinity side to the highest one leaving all salts behind.

Antiscalants

It is anti-scale material for salts in feed water it is injected in pretreatment stage before water flowing to RO membranes . it is used to delay the reaction between bicarbonate and calcium magnesium that results in preventing any scale on membranes.

Sterilization

A technique used to eliminate any organisms in water as they are very harmful to people health and that is done by may physical techniques :
1-chlore
This is done by the addition of some chemicals to perform a reaction results in some materials to purify water by eliminating these organisms and those chemicals are mainly chlore like hibocholorous acid and its derivatives like chloro oxide and calcium hibochorite.
2-Ozone(O3)
To produce ozone we need to engage an oxygen atom to two united oxygen atoms and this is done by using ultraviolet rays to do that. when ozone is mixed with water it becomes an effective material to eliminate all harmful organisms in water.

3- Ultraviolet rays
It is less effective than ozone in water purification so it is used in small projects and specific waters. ultraviolet rays is eliminating all bacteria by damaging their DNA and stops them from growing in number .
