Condensate water treatment at a dairy plant

SILHORKO-EUROWATER took part in a steam boiler water modernization project at a dairy plant belonging to a large international company.

Returning the hot condensate back to the boiler saves water and fuel. In this case, however, the condensate quality was not 100% pure, clean water, and further water treatment was required. Therefore, the main job was to upgrade the water treatment system on the steam boiler. The solution consists of:

• Removal of particles and iron in a bag filter. The special bag filter is completely in stainless steel and can operate in pH range between 3 and 13, and water temperature up to 100°C
• Removal of hardness in an ion exchange duplex softening unit with SE20 PLC control panel. The unit is designed for hot water up to 85°C
• Both units are insulated in order to reduce temperature loss
• Dosing system for pH control including measuring equipment and digital dosing pump for NaOH dosing
