Corrosion inhibitors play a vital role in water treatment environments, offering protection against the damaging effects of corrosion in various applications.
In boiler applications, corrosion inhibitors are essential for safeguarding boiler systems from the detrimental impact of corrosion caused by dissolved oxygen and other contaminants in the water. By forming a protective barrier on metal surfaces, corrosion inhibitors help extend the lifespan of boiler equipment, improve operational efficiency, and minimise the risk of costly repairs and downtime.
In closed loop applications, corrosion inhibitors are employed to protect the integrity of closed loop heating and cooling systems. These inhibitors prevent corrosion and scale formation within the system, ensuring optimal performance and efficiency over time. By maintaining water quality and system cleanliness, corrosion inhibitors help prolong the service life of closed loop systems and reduce maintenance requirements.
Cooling water applications also benefit from the use of corrosion inhibitors, which help mitigate the corrosive effects of water on cooling equipment such as heat exchangers, condensers, and cooling towers. By forming a protective film on metal surfaces, corrosion inhibitors prevent metal degradation and maintain the efficiency and reliability of cooling systems, ultimately reducing operating costs and extending equipment lifespan.
In food can protection applications, corrosion inhibitors are utilised to safeguard metal cans and containers used for food packaging. These inhibitors prevent corrosion and rust formation on can surfaces, ensuring product integrity and shelf stability. With corrosion inhibitors, food manufacturers can maintain the quality and safety of their products while meeting regulatory requirements for food packaging materials.
Additionally, corrosion inhibitors find application in specialty and multi-use environments, where they offer tailored protection for specific industrial processes and equipment. Whether in automotive manufacturing, chemical processing, or marine applications, corrosion inhibitors provide versatile and effective protection against corrosion, preserving the integrity and longevity of critical assets and infrastructure. With their wide-ranging applications and benefits, corrosion inhibitors are indispensable components of comprehensive water treatment strategies, supporting the reliability, efficiency, and safety of various industrial processes and systems.
Product and customer insights
CHALLENGE A 40-hectare raw water storage dam had persistent issues with blue-green algae (BGA) blooms, leading to taste and odor problems. Despite the presence of an aeration system to address water stratification and mixing, BGA counts remained seasonally high, particularly in summer and autumn. Upgraded aeration in 2018 did not resolve the issue, leaving the […]
The International Maritime Organisation (IMO) regulation, known as IMO 2020 was the the largest change in regulation relating to marine fuels impacting 75% of the fuel used by the shipping industry.
CHALLENGE A power plant relying on ultrafiltration (UF) and reverse osmosis (RO) faced a critical operational challenge. A wastewater treatment upset severely fouled the UF system, drastically reducing water production. Despite multiple cleaning attempts with sodium hypochlorite and citric acid, transmembrane pressure (TMP) remained high, and flux showed no improvement. The plant’s inability to meet […]
Keeping drilling costs low using Redi-Guard™ High Performance, an ecologically friendly drilling fluid technology with revolutionary rheological and shale encapsulation properties
CHALLENGE A municipal water reuse plant processing 8 million gallons per day (MGD) experienced severe fouling and scaling issues, including calcium phosphate and silica deposits. With steep feed pressure increases and differential pressures in both stages, the plant required frequent cleanings every 4 to 6 weeks, amounting to 32 cleanings annually. Each cleaning cycle resulted […]
The plant was experiencing weekly shutdowns for fiber clean up (~ 3 kg bags of matted slurry is cleaned per week). The shut downs were costly as they reduce plant availability for production.
CHALLENGE A municipal reverse osmosis (RO) plant on Florida’s west coast, with a 20 MGD capacity, faced high operational costs due to its reliance on 93% sulfuric acid for pH adjustment. The plant used a combination of a brackish water reverse osmosis (BWRO) membranes and fiberglass-wrapped membranes across 10 trains, each operating at 75% recovery. […]
CHALLENGE A gold processing plant in New Zealand sought to improve gold recovery efficiency while addressing high Total Organic Carbon (TOC) levels. Elevated TOC increased the Preg-Robbing Factor (PRF), reducing the plant’s ability to efficiently recover gold during the Carbon-In-Leach (CIL) process. The traditional use of kerosene as a carbon blanking agent offered limited efficacy, […]
CHALLENGE A municipal reverse osmosis (RO) plant, with a capacity of 2 million gallons per day (MGD), faced frequent system cleanings, every 2-4 months, due to rising feed pressure. The plant, which sources water from brackish wells and uses Toray TMG-20D-400 membranes in a (16×7) -> (8×7) train configuration, was operating at 78% recovery. Despite […]
Research indicates that Sea Buckthorn may be able to strengthen the immune system. One in vitro study focused on the possible immunomodulatory properties of Sea Buckthorn.
AWC A-110 effectively inhibited scale at a dosage of 3.5 ppm and an operating pH of 6.9. This increase in operating pH reduced the district’s annual acid consumption by ~$350K per year based on their current production.
MCI® -2020 V/O and ChemMaster’s Colorsil were chosen to repair and protect the walls based on their 20 year warranties and the fact that together they could fulfill the other specified repair design requirements.
Despite numerous cleanings, the productivity of the Reverse Osmosis plant would not recover from severe membrane fouling. The membrane autopsy revealed that the ferric hydroxide was seeding
silica polymerization and that even while the ferric hydroxide was removed, the silica scaling was continuing to grow.
The East Hokkaido region is known to have the highest volume of potato product in Japan. Unfortunately, a potato farmer in the area was experiencing a high rate of potato scab infection in his agricultural field.
