The World's Most Powerful Membrane Antiscalant Software

proton membrane chemistry

Our Proton® Aqueous Membrane Chemistry Calculator is the world’s most powerful membrane antiscalant projection software. Proton can be used to design a new RO/NF system, performs a complete suite of hydraulics calculations, and accounts for tail element concentration polarization in its scaling calculations. The software accounts for ion activity and for over 130 ion complexes making it the most accurate projection software in the industry. It is the only membrane software to calculate the saturation and precipitation potentials for over 50 scales at the entire operating pH range of 1 – 11. Proton also projects water quality and reliably predicts rejection of contaminants such as boron, arsenic and bromide.

  • AWC’s cleaning chemicals have performed outstandingly in cleaning our ceramic microfilters and RO membranes at various industrial wastewater recycling facilities throughout the US and around the world. Although we have tested numerous other chemicals under many different conditions, we have not found any products that perform as effectively as AWC’s cleaners.

    OEM for Industrial
  • Since the start-up of this plant in 2003, we have experienced biofouling issues that required us to clean every 28 days. However, since we started using the AWC A-102 Plus, we have been able to extend the frequency between the cleaning of membranes from 28 days to 20 weeks.

  • The use of sulfuric acid is eliminated, resulting in a great increase in plant safety. Our cleaning interval has gone from 6 months to over a year. We had much more fouling on acid.
