We offer membrane antiscalants, antifoulants, cleaning chemicals and analytical services for reverse osmosis (RO), nanofiltration (NF), ultrafiltration (UF) and microfiltration (MF) membrane purification systems.

Through our U.S. based partners we can access advanced membrane autopsy techniques and investigative services.  We  help authorities and businesses to identify causes of operational problems, improve membrane system performance and reduce cost through provision of scientifically engineered solutions. We can help our customers to reduce their operating costs and frequency of cleaning with its associated down-time.

Our range of reverse osmosis/nanofiltration antiscalants and antifoulants can help eliminate problems of difficult water chemistry, especially related to calcium and barium scaling as well as iron and silica fouling and membrane biofouling in RO and NF systems.  Our unique software tool allows you to investigate and optimise your treatment and plant operation.  Let our team of specialists help solve your most challenging problems.

PROTON®: Membrane Aqueous Chemistry Calculator

PROTON® is a powerful state of the art antiscalant software package created by American Water Chemicals (AWC). PROTON® is the first antiscalant software that can design a reverse osmosis system, and account for membrane properties and flux rates at the various stages of a system.

PROTON® Advantages

  • Allows the user to compare the required feed pressure and permeate water quality for various membranes under identical conditions.
    Once the design is selected, the user can simply select a different membrane type, and can instantly see the impact on pressure, water quality and scaling potential. The user can see real time impacts of changes in pH, temperature or recovery on pressure, flux and permeate quality.
  • Accurately calculates boron rejection with varying pH, accounting for both temperature and ionic strength, and differentiating between rejection by nanofiltration, brackish, and seawater membranes. Other contaminant rejections that are calculated include iron, manganese, aluminium, ammonia, nitrate, nitrite, sulfides.
  • Only software currently available that predicts arsenic rejection with varying pH, temperature and ionic strength.
  • Provides calculations that help with design of pretreatment coagulation and post treatment degasification.
