Understanding Cycles of Concentration

Evaporative systems are more complex to treat than closed systems. Why? It’s because the solid impurities become increasingly concentrated in the system water during the normal course of operation. Makeup impurities do not typically concentrate in closed systems. In evaporative systems, large quantities of water are used on an ongoing basis. Economics dictate the use of chemicals that can be applied at low dosages. Closed systems normally use only the amount of water required to fill the system one time and any water losses from leaks and repairs.

Your Dirty AC Coils Could Be Costing You Big Time

Air conditioning (AC) systems that do not function properly can be cumbersome. Properly maintaining these units is critical––especially the coils, whether they are in an air handling unit or a packaged air conditioning unit. These delicate coils require regular upkeep to preserve the life of the AC unit, maintain capacity, improve energy efficiency, and ensure the indoor air quality is at its best.

The Effects of Carryover in Steam Boiler Systems

Carryover is any contaminant that leaves the boiler with steam. It can be in a solid, liquid, or vapor form. The most common form of carryover is boiler water droplets that contain dissolved and suspended solids.

Boiler water carryover can cause deposits to form in valves, heat exchangers, turbines, and superheaters. If deposits are significant, heat transfer and/or turbine efficiency may be reduced. Additionally, carryover can strip away the protective magnetic layer on steam lines, remove the film formed by filming amine programs, cause erosion-induced corrosion, and result in product quality problems in processes using live steam.

Identifying Types of Corrosion in Water Systems

How to be Better Prepared

Identifying Types of Corrosion in Water Systems

Corrosion in water systems is a costly problem.  In the United States alone, the costs associated with corrosion in water and wastewater systems are estimated to exceed $50 billion annually. The metal loss resulting from corrosion reduces system life, increases maintenance costs, and ultimately results in premature equipment failure. Corrosion can also produce deposits that impede water flow, foul heat exchange surfaces, and reduce overall water system efficiency.  A basic understanding of the different types of corrosion can help you diagnose and solve corrosion related problems.
