Filtration Options for Closed Loop Systems

Closed loop systems, typically hot and cold water recirculating systems, are often ignored when it comes to water treatment programs. Not only should closed loops be chemically treated to control corrosion and microbiological growth, they should also include a side-stream filter to remove suspended solids. 

Even though closed loop systems are theoretically “closed,” suspended solids can still be introduced as a result of corrosion, new construction, new additions to older systems, leaks, and poor commissioning practices. Turbidity or discoloration can be one sign of suspended solids.

How To Prepare Your Cooling Towers for Winter

With the cooler months upon us, it is important to prepare your cooling towers for freezing temperatures. Even in extremely icy conditions, cooling towers can be operated successfully if proper precautions and protocols are followed. A frozen cooling tower is a major issue for business operations as well as from a cost standpoint.  Now is the time to prepare for winter weather.

Combating Corrosion with Chem-Aqua

Corrosion costs money.  In fact, water system corrosion costs an estimated $50+ billion annually in the United States alone.  System life, maintenance costs, production time, deposition, and efficiency are all negatively impacted by corrosion.

How to Prepare Your Boiler for an Inspection

Periodic boiler inspections are necessary to ensure that all equipment and components are operating safely and properly. When removing a boiler from service, the proper procedures should be used to reduce thermal stress and prevent sludge from settling and “baking on” waterside surfaces.

If a boiler is cooled too rapidly or unevenly, the extreme expansion and contraction stress can cause leaks to develop on rolled tube ends as well as damage firebrick or refractory material. Rapid cooling and draining can also cause any suspended solids in the boiler water to form hard, difficult-to-remove deposits. These deposits not only reduce heat transfer efficiency but could also lead to a false interpretation of the treatment program results.

Biofilm, Amoeba, and Legionella

Biofilms are the root cause of serious problems in building potable and industrial water systems including clogged piping, reduced heat transfer efficiency, microbiologically-influenced corrosion, and Legionella transmission. Biofilms are dynamic, complex structures optimized for microbial growth and survival, which make them difficult to remove and control.

How Reverse Osmosis Works

From Design to Cleaning

How Reverse Osmosis Works

Reverse osmosis (RO) produces high-purity water for use in many applications, including low and high pressure boilers, manufacturing processes, cleaning, and ultrapure water systems. RO offers numerous benefits that can save water, fuel, operating costs, labor, and more. Understanding how it works will help in the selection, maintenance, and operation of RO systems.

Why Water Needs to be Treated

Water Treatment consists of three crucial factors: Service, Chemistry and Equipment. It is an important part of the preventative maintenance program for boiler, cooling, and process water systems. With the right partner, you can ensure to have a reliable and well-working system that will minimize cost, maximize efficiency and provide sustainable solutions.

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.

The Importance of Preventative Maintenance

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 magnetite 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.
