Advantages of Deaerator

Reduce oxygen content in boiler feed water

Reduce chemical consumption especially sulphite directly and others chemical indirectly.

Reduce chemical consumption and resulted less blowdown due to lower TDS from carry over, and more cost efficient.

Automation of operation by modulating level control shall optimize deaerator performance

Indirectly prolong boiler lifetime and others associate equipment such as valve, piping, pumpset and deaerator vessel due to oxidize corrossion

The process is denoted as below: -

Cation ion exchanger
Mg + 2R(H)⁺ => 2R(Mg) + 2(H) (R denoted as resin)
Which hydrogen solution present as cationize free water, whereby cationic particles shall be bonded to resin until a regeneration with acid solution (HCL) is introduce.

The regeneration process is denoted as 2R(Mg) + 2(H)à Mg + 2R(H)⁺ which the cationic particle is drain out during regeneration process when acid solution is ejected to cation exchager unit. The process will repeat when the resin is fully regenerated.

Anion ion exchanger
Si + 2R(OH)^- => 2R(Si) + 2(OH) (R denoted as resin)
Which hydroxyl solution present as anionize free water, and combine with cationize water as demineralizer water for process / boiler; whereby anionic particles shall be bonded to resin until a regeneration with caustic solution (NaOH) is introduce.

The regeneration process is denoted as 2R(Si) + 2(OH)à Si + 2R(OH)^- which the anionic particle is drain out during regeneration process when caustic solution is ejected to silica removal unit. The process will repeat when the resin is fully regenerated.

As for boiler feed water, mineral present shall form scale at wall of the boiler, in which is very difficult to remove by chemical process. Hence reduce the combustion efficiency of the boiler. As a result, more boiler fuel is required.

Ease operation with fully automatic by timer controller.

Pre-set to desire regeneration cycle and have a peace of mind on operation and performance

Reverse Osmosis (MRO- Series) is an essential part of ultra pure water as process and boiler feed water system. Corrosion in boiler cycle is mainly cause by the presence of dissolved solids categories as cationic and anionic component aided by a low pH value, however, pH can be raised by addition of chemical during operation. Nevertheless, removal of dissolved solids must be done by water kinetic or ion exchange process. This water kinetic process is known as Reverse Osmosis and its employ great pressure of water pass through a membrane in solids housing to purify the water and increases the life of mechanical components and system dramatically.

Generally, dissolved solids are found in dissolved properties and it will replace it during ion exchange process. As for hardness removal, property of hardness commonly found in MgCO32+ and CaCO32+, sodium form in ion exchange resin is introducing in NaCO32+ form and replacing the hardness in the water by Sodium (Na+) in ion exchange process as Na+ is relatively stronger in ionic bonding in chemistry covalent chart.

The process is denoted as below

Mg + 2R (Na) + => R (Mg) + 2(Na) (R denoted as resin)

Which softened solution present in sodium form and feed to boiler; whereby hardness shall be bonded to resin until regeneration with brine solution (NaCL) is introduce.

The regeneration process is denoted as 2R (Mg) + 2(Na) => + 2R (Na) + + Mg which the hardness and chloride is drain out during regeneration process when brine solution is ejected to water softener.

The process will repeat when the resin is fully regenerated.
