A S Harrison & Co, in association with international manufacturer – American Water Chemicals (AWC), can provide you with leading edge water treatment focussing on reverse osmosis membrane chemicals for desalination and industrial water treatment.
Our solutions can help you in reducing operating costs and frequency of cleaning. AWC chemicals are approved for all membrane types and NSF 60.
Why choose AWC products?
AWC manufactures membrane antiscalants, biocides, antifoulants, and cleaning chemicals for reverse osmosis (RO), nanofiltration (NF), ultrafiltration (UF), and microfiltration (MF) membrane systems.
AWC was created in 1993 as a subsidiary of a water treatment equipment manufacturer (OEM) in response to its operations engineers’ demands for more reliable RO chemicals. They required RO antiscalants that were more resistant to biological fouling and had a better tolerance to iron. More effective membrane cleaning chemicals were needed to restore membrane performance during the warranty period. In just a few years, AWC developed into an independent operation that provided membrane chemicals and autopsy services to water treatment plants around the world.
AWC is very unique among its competitors in that it dedicates significant resources to understanding complex scaling phenomena through research and development.
AWC also offers a broad range of analytical services including membrane wet testing, membrane cleaning studies, and membrane autopsies. Having pioneered the use of elemental imaging for membrane autopsies, AWC uses its advanced Superimposed Elemental Imaging (SEITM) technique to provide meticulous reports that identify the exact nature of a scalant or foulant. For over 20 years, American Water Chemicals has provided the membrane community with RO chemicals that lower operating costs, eliminate hazardous acid dosing and reduce the frequency of membrane cleanings.
In the past decade, AWC has created potable water corrosion inhibitors designed specifically for use with RO permeate, and a new line of NSF approved MF/UF cleaning chemicals.
The Benefits of the AWC ROSSEP Process
AWC has developed a process that simulates your water quality and system conditions so as to guarantee the recommended pH and antiscalant dosage for your operation. This process predicts the outcome of a RO/NF pilot for control of inorganic species without interference from organic, biological, or colloidal materials which would be present in a field study.
ROSSEP is an acronym for Reverse Osmosis Scaling Synthetically Emulated by Precipitation.
Product and customer insights
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 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.
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
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.
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.
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.
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.
