What is Scale and How does it Impact Water Treatment?

Hard water has been causing issues for humanity for ages, whether it is making it difficult to wash our clothes and cars, or depositing on our hot water heaters and kettles. Hardness scale is typically the combination of calcium and magnesium compounds that have precipitated out of water (e.g., calcium carbonate, magnesium silicate). This tough deposit forms in HVAC cooling systems and process water systems and can wreak havoc by decreasing system life and increasing energy usage, maintenance, and operational costs.

What are filming amines and how do they protect your system?

Treating Boiler Condensate with Filming Amines

Steam is the life blood of many buildings and manufacturing operations. When companies are looking for ways to lower operating costs and ensure reliability, the steam boiler system is a good place to start. After steam does its work, it becomes condensate, which is often referred to as “liquid gold” due to its low dissolved solids and high heat content. Maximizing the recovery of condensate reduces utility costs and conserves natural resources. As a rule of thumb, every gallon of condensate that is returned to make more steam saves a cubic foot of natural gas.
