Improving Odor Control Scrubber Performance

Improving Odor Control Scrubber Performance

“Smells like money” is what you often hear as you walk into a rendering plant, normally accompanied by the speaker taking a deep breath. To the uninitiated, the smell is nothing like the paper bills in your wallet. It is a deeper richer smell - much like the inside of a pet food bag. More than the smell of "money," it is the smell of recycling and sustainability.

The rendering industry is the original recycler, transforming waste materials from farmers, restaurants, food producers, etc. into products for pharmaceuticals, cosmetics, animal feed, renewable fuels, and more. The process of converting this material into proteins and oils is accompanied by vapors that create odors, environmental concerns, health hazards, and damage to equipment and facility infrastructure.

Identifying Common Steam Boiler System Failures

Identifying Common Steam Boiler System Failures

Steam boiler systems are complex with not only the physics of the mechanical side to worry about but the chemistry of the water side as well. There are many problems that can occur that will impact boiler reliability. The mechanisms that can lead to failures in a steam boiler system can often be identified if you know what to look for. Here are five (5) common causes of waterside failures with pictures and descriptions to help you recognize them.

Understanding How ORP Is Used in Cooling Water Treatment

Understanding How ORP Is Used in Cooling Water Treatment

Properly measuring ORP (Oxidation-Reduction Potential) and understanding its limitations when used to monitor and control oxidizing biocide feed is important to minimize the potential for increased corrosion rates, excessive chemical feeds, and biofouling.

How Boiler Water Treatment Affects Hospital Steam Purity

Steam Purity is a measure of all contaminants in steam, with high-purity steam containing only trace amounts of contamination. Maintaining high steam purity is important in many industries, but there are few applications where it is more critical than in healthcare facilities that use plant steam for surgical instrument sterilization and/or operating room humidification. In a hospital, any contaminants in the steam could potentially interfere with proper sterilization as well as be inhaled by hospital patients, staff, and visitors. Understanding how and where to add the water treatment chemicals and the factors that can cause boiler water carryover will help hospitals ensure that high-purity plant steam is consistently produced.

Reducing Water Costs in Building HVAC Systems

Reducing Water Costs in Building HVAC Systems

The HVAC system is the largest user of energy and water in typical commercial buildings. In the past, energy costs overshadowed water costs. Recent droughts and the need to expand municipal water supplies to support growth have led to increased water costs nationwide. Combined with the focus on water conservation in green buildings, the payback associated with reducing building water usage is greater than ever. Most commercial buildings use water cooled chillers to provide air conditioning because they are much more energy efficient than air-cooled chillers. Achieving these efficiencies, however, requires large quantities of water to operate a cooling tower. Most buildings also use re-circulating hot and chilled water loops to distribute heating and cooling throughout the building. Although not designed to routinely use water, these systems can use large amounts of water if undetected leaks occur. As the major consumer of water, the building HVAC system is an obvious target for water conservation efforts and often provides significant saving.
