Reverse Osmosis Maintenance

Membranes, Chemical Dosing, Filters, Meters, Hoses

Whether it is the larger membrane units connected to bores, or the much smaller units often seen under the sink, regular maintenance is required to maintain optimum performance and to minimise the chance of equipment failure.  Large membrane reverse osmosis is not a cheap option and the water from it is often used for human consumption, irrigation of fruit and vegetables, or as part of a business.  You don’t really want to run out of water and you don’t want to produce poor quality water.

The reverse osmosis system is typically made up of a number components that will require regular checking.  Some of these are;

  • Water supply (typically a bore)
  • Pre-filtration
  • Chemical Dosing
  • Reverse Osmosis membranes
  • Gauges
  • Hoses

The kinds of problems that are often seen with reverse membranes encompass;

  • A drop-in production
  • Leaks
  • Hose degradation
  • Dirty Gauges
  • Faulty meters particularly total dissolved salts (TDS)
  • Dosing pump failure
  • Incorrect dosing – under or over dosing
  • Empty chemical dosing tanks or incorrect dilution

Smaller units, typically under the sink, are simpler in design but still require changing of filters and changing of cartridges. The photo below is a filter removed in metropolitan Melbourne – it is very dirty.

Another common problem often seen in small units is not changing carbon filters.  Carbon is an excellent filter medium removing a wide range of chemicals.  These chemicals bind to the carbon and therefore the carbon filter will need to be replaced to ensure that chemicals are removed.  A carbon filter cannot be washed or cleaned to return it to its original condition.
