Avista Technologies provide a wide range of specially formulated cleaners to tackle all common membrane foulants. These foulants include metals, inorganic scales, silt, organics and biological material. The table below summarises the application of each product and a more detailed description is given overleaf.

All products are applied as dilute solutions made up with permeate or good quality potable water. All products are readily mixed / dissolved for use. The solutions are optimally applied heated to the maximum temperature and re-circulation rate specified by the membrane type.

Avista Technologies technical staff are always available to advise on product choice for each application. Cleaning trials can also be carried out in our off-site 'OSCAR’ facilities or on our cell test equipment to demonstrate effectiveness prior to application on site. This can be helpful in determining whether a broad-spectrum cleaner or targeted cleaner is most effective in removing the foulant on the membrane.
