The quality of water entering a boiler, cooling, or process system can have a significant impact on water, energy, and system efficiency. Raw makeup water can come with many different types of impurities, including dissolved and suspended solids, which can lead to energy-robbing scale deposits and equipment-damaging corrosion. Pretreatment equipment removes unwanted impurities from raw makeup water before they can cause problems in industrial water systems.
There are many types of pretreatment, with each impacting water quality in its own unique way.
Water quality is highly important in a boiler water system. Scale deposits can be insulating and negatively impact fuel efficiency by impeding heat transfer. Corrosion can reduce the lifespan of boiler system equipment, resulting in downtime and lost production. A well-implemented water treatment program will allow the boiler system to operate using both a minimum amount of water and energy.
Scale deposits and corrosion can have negative impacts on a cooling tower system by reducing heat transfer efficiency, increasing downtime, and decreasing equipment lifespan. Applying the appropriate pretreatment technologies can help both the cooling tower and the systems it supports run more efficiently.
While designed to avoid direct air contact and evaporation, closed recirculating water systems can still experience insulating scale and microbiological deposits as well as equipment-damaging corrosion. Implementing the appropriate pretreatment technology can help mitigate these problems.
Process water systems provide water for a variety of manufacturing processes with a range of water quality requirements to keep the systems running efficiently. Examples include cleaning baths, chemical blending, cutting, product components, etc. The pretreatment equipment required will depend upon each system’s unique requirements.
Potential problems caused by inadequate pretreatment include, but not limited to:
