Boiler Feed Water & Cooling Water Treatment
At Glorinda, we design and deliver boiler feed water and cooling water treatment systems that protect equipment from scaling and corrosion, keeping fuel consumption, downtime, and maintenance cost under control.
Boiler Feed Water & Cooling Water Treatment
Boiler feed water treatment prepares water for the steam cycle, removing hardness, silica, and dissolved ions before it reaches the boiler. Cooling water treatment addresses the same water quality issues on the heat-rejection side, in cooling towers, heat exchangers, and closed loops. Together, they determine plant efficiency, as poor water quality shows up in higher fuel consumption, faster corrosion, and increased maintenance cost.
Your solution can be a better utility water train.
“Cooling tower blowdown is wasting a lot of water”.
What problem does it solve?
Cooling towers also need blowdown to prevent TDS build-up, which means significant water loss. On thermal power plants, cooling towers are typically the largest water consumer on site. Glorinda designs water treatment systems that improve water quality, efficiency, and resource recovery across industrial utility systems.
Benefits
Protect the asset
Demineralisation, softening and polishing designed to stop deposition and corrosion before they cost you tube replacements and unplanned outages.
Efficiency you can measure
Clean heat transfer surfaces mean less fuel per unit of steam and better condenser vacuum.
Blowdown becomes make-up
Cooling tower blowdown recovery through MLD or ZLD turns the largest water loss on a thermal site into recovered make-up water.
Condensate polishing
Returned condensate can carry metallic impurities and corrosion products that reduce steam quality and equipment life. Ion exchange and mixed bed polishing protect the Rankine cycle.
Chemical-free options
EDI removes acid and caustic regeneration from the demin plant; on-site hydrogen peroxide removes chlorine from the cooling loop.
Instrumented properly
Conductivity, pH, dissolved oxygen, silica and hardness monitoring so that the plant knows what its water is doing rather than discovering it at the next inspection.
How it works
Two distinct water trains usually run on the same site, drawing on the same technology set.
The steam side needs progressively purer water: pre-treatment, reverse osmosis, then ion exchange, mixed bed, or electrodeionization to reach the required conductivity, with condensate polishing on the return.
The cooling side needs stable chemistry, scale and fouling control, and a blowdown recovery strategy.
01
Demineralised water production
Plants need water with very low conductivity for the steam cycle; dissolved ions damage steam equipment. The standard train is reverse osmosis followed by ion exchange units and a mixed bed polisher, or electrodeionization where chemical regeneration is unwelcome.
02
Boiler feed water treatment
Hardness, silica and dissolved ions cause deposition on boiler tubes, reducing heat transfer and increasing corrosion and energy consumption. Ion exchange, EDI and mixed bed treatment address it, and boiler feed quality is critical for stable operation on any steam-raising plant.
03
Condensate polishing
Water returning from the condenser may contain metallic impurities, corrosion products or cycle contamination, which reduces steam quality and equipment life. Ion exchange and mixed bed polishing keep the returned condensate at the quality the Rankine cycle needs.
04
Cooling water optimisation
Poor water quality causes scaling, corrosion and fouling in heat transfer equipment. Filtration and advanced treatment maintain heat transfer; on-site hydrogen peroxide controls biofilm without the corrosivity of chlorine.
05
Blowdown recovery
Blowdown carries high dissolved solids and represents a large water loss. Membrane recovery through MLD returns most of it as make-up; where the concentrate cannot be discharged, ZLD closes the loop entirely.

Which treatment train suits your needs?
Selecting a boiler feed water and cooling water system is an engineering decision, not a purchasing one. We evaluate your water analysis, steam pressure, and site utilities, compare the options on capital and operating cost, and act as owner’s engineer while somebody else builds it if that suits you better.
Frequently asked questions
Hardness, silica and dissolved ions deposit on boiler tubes, reducing heat transfer. That means lower steam efficiency, higher fuel consumption, corrosion and higher maintenance cost. It is one of the main points on any plant where high-quality water is genuinely required rather than merely preferred.
On a thermal plant, the cooling tower is one of the largest water consumers on site, and blowdown is a high-TDS stream discharged purely to stop dissolved solids accumulating. Recovering it reduces both fresh water consumption and effluent disposal cost, which is why it is one of the first water optimisation projects we are asked about.
EDI if you want to eliminate acid and caustic handling and regeneration waste, and if space is tight — its initial investment is about 20% higher but operating costs and maintenance are lower. Mixed bed if capital cost dominates and the chemical infrastructure already exists. The full comparison is on the ion exchange and EDI page.
Yes. Flue gas desulfurization produces a complex effluent with sulphate, chloride, heavy metals and high TDS, for which conventional treatment is not sufficient. That needs advanced wastewater treatment and, in many cases, ZLD.
Yes. Liquid analyser systems measuring pH, ORP, conductivity, TOC, chlorine, ammonia and dissolved oxygen are part of our analyzer and metering product line. Liquid analysis is how you protect boilers and cooling towers from corrosion and maximise uptime.
