Corrosion inhibitors are crucial for extending the lifespan of construction materials. A S Harrison & Co offers a comprehensive range of products to address various corrosion challenges in the construction industry, ensuring the longevity and integrity of structures.
CorrVerter® is an innovative, fast-drying, water-based primer specifically designed to combat rust. This one-coat system converts rusted surfaces into a hydrophobic passive layer, effectively preventing further corrosion. Its unique formulation, which includes chelating agents and PVDC resins, ensures long-lasting protection, making it ideal for treating rusted metal surfaces in construction.
MCI® (Migrating Corrosion Inhibitor) admixtures are essential for concrete construction. These admixtures are based on advanced amine technology, utilising amine alcohols and amine carboxylates. By integrating MCI® admixtures into concrete, the lifespan of structures is significantly extended as they provide robust protection against corrosion, even in harsh environments. They work by migrating through the concrete to form a protective layer on the reinforcing steel.
For concrete restoration projects, MCI® repair products are indispensable. These products are specifically formulated to ensure the longest possible lifespan for repaired concrete. MCI® repair solutions slow the rate of corrosion and safeguard against the ring anode/incipient anode effect, which is a common issue following concrete repairs. This results in more durable and lasting concrete restorations.
A S Harrison & Co also offers MCI® specialty products tailored for various aspects of the construction industry. These include corrosion inhibitors for concrete cleaning, rebar storage, and rust conversion. These specialty products provide flexibility and targeted solutions to meet specific construction needs, ensuring comprehensive protection against corrosion.
MCI® surface treatments are designed for application on existing structures to reduce corrosion rates. These treatments penetrate and migrate through cementitious materials to reach and protect embedded reinforcing metals. By applying MCI® surface treatments, construction professionals can significantly enhance the durability and lifespan of their structures.
The VpCI® (Vapor Phase Corrosion Inhibitor) technology is pivotal for preventing corrosion in plastics, elastomers, and adhesives. Particularly useful in construction, VpCI® ensures that materials like polyethylene and polypropylene are safeguarded against corrosion. This dual protection through contact and vapor phase inhibitors enhances the reliability and longevity of construction materials.
By incorporating these advanced corrosion inhibitors, the construction industry can achieve greater durability and sustainability in their projects.
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.
