Water is widely used in various processes in heating applications, due to its good heat transfer capacity.

Depending on water source and its properties, treatment might be required. Depending on the type and material of the boiler, several parameters shall carefully monitor to prevent corrosion, fouling and scaling. While recirculating condensed water and due to evaporation losses, the amount of dissolved minerals increases in the system. 

Common water sources are well water, surface water, reused waste water and sea water.

Boiler manufacturers typically provide limiting and recommended parameters, like conductivity, total dissolved solids, pH, because the water will be transformed into a steam for heating applications.  Therefore, water treatment is always required in the make-up water of a boiler.

Water treatment of make-up water will depend on the source of water and boiler manufacturer requirements: suspended solids removal, dissolved solids removal, softening, pH adjustment, dosing of biocides for bacterial control, dosing of anticorrosion agents.

Lenntech develops innovative solutions with the combination of a wide range of technologies for boiler make-up water treatment according to the source of water and Boiler requirements: ultra-filtration, activated carbon, multimedia filtration, reverse osmosis, closed circuit reverse osmosis, ion exchange softening, electro-deionization, electro-dialysis reversal, chemical conditioning.

Make-up water treatment allows to optimize the boiler processes, reduce the blowdown rate and assume a high-quality stream. The energy consumption will decrease as well. Benefits of make-up water treatment include:

• more stable water quality,
• lower fouling and corrosion,
• reduction of chemicals used,
• Process optimization.

Lenntech provides sustainable and complete solutions for boiler make-up treatment considering a wide range of technologies and strategies. With worldwide growing water demand and water scarcity, our solutions are suitable for reducing boiler operational costs and water footprint.

Our advantages

• Engineered and custom designed solutions for unique cooling tower blowdown water treatment systems and specific equipment needs.
• Turn-key solutions including design, engineering, manufacturing, automation, installation, maintenance and training.
• State-of-art technologies for effective water and wastewater treatment, recycling, reuse, and disposal.
• Best on-line assistance and on-site service and support.

Boiler water quality shall be set according to the boiler pressure and type of heater.

Lenntech can provide you all water treatment equipment, including chemicals. Chemicals will condition the water and protect boiler equipment (heater, pump, …).

Lenntech can advise you on treatments required on the make-up water, by providing calculations on mass balance in the steam boiler, contributing for lower electricity consumption.
