Reverse osmosis (RO) is a highly effective water filtration process used in various applications to produce clean and pure drinking water. RO systems employ semipermeable membranes to remove contaminants, dissolved solids, and impurities from water, delivering high-quality water for consumption and other purposes.
Powerful antiscalants play a crucial role in reverse osmosis systems, allowing for higher system recoveries and cost-effective operation. These antiscalants effectively inhibit the formation of mineral deposits on the membrane surface, preventing scaling and fouling. Environmentally compatible antiscalants are particularly beneficial for applications where waste discharge into the environment is a concern. Other options such as Veraflux, is a phosphorous-free, super-concentrated reverse osmosis antiscalant designed to reduce shipping costs while providing excellent scale inhibition in RO/NF feed water systems.
Membrane cleaning chemicals are essential for maintaining the efficiency and longevity of reverse osmosis membranes. Formulated for all types of RO membrane systems, these cleaning chemicals effectively remove fouling, biofilm, and debris from the membrane surface, ensuring optimal filtration performance. Whether used in food and beverage applications or water reuse systems, membrane cleaning chemicals are indispensable for preserving the integrity and effectiveness of reverse osmosis membranes.
Overall, reverse osmosis is a powerful water filtration technology that offers reliable removal of contaminants and impurities from water. With the support of powerful antiscalants, RO systems can achieve higher recoveries and cost-effective operation, while membrane cleaning chemicals ensure the continued efficiency and performance of RO membranes.
By employing these advanced technologies and maintenance practices, reverse osmosis systems provide a dependable solution for producing clean and pure drinking water, meeting the needs of various industries and applications.
Product and customer insights
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 […]
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 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. […]
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.
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 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.
