Activated carbon services are required for many waste water treatment systems. Activated carbon filters help to make waste water reusable, are easy to install and maintain and don’t have a very high operating cost – these factors help to make activated carbon a popular choice among waste water management professionals.

Activated carbon does allow bacterial growth over time. Such bacterial growth can plug and coat the activated carbon, reducing the effectiveness of the filter. It can also introduce bacteria into your drinking water which poses a risk if servicing isn’t frequent. While silver is often added to the activated carbon media of some filters claiming that it helps in controlling bacteria growth, this has been proven wrong by the U.S. Environmental Protection Agency (EPA) sponsored tests. Only regular filter replacement helps in reducing bacteria build-up.

Despite the quality of the equipment you have, it may not perform well unless it receives proper maintenance, cleaning and replacement of the activated carbon. Depending upon the unit type the service period will vary. It is always advisable to keep a record of when you last made use of activated carbon services for your respective water filters.
When it comes to small specialty water filters, the entire unit can be replaced whereas the units that employ cartridge filters are usually the easiest to change. Before you purchase a unit, you should also consider the cost of replacing the activated carbon filters.

Service periods vary greatly. Smaller water filters with a heavy load of contaminants may require replacement every month or even every three weeks. Cartridge filters tend to have a six month service interval period. Since filters will only treat a given volume of water effectively, it is advisable to have a water meter installed on the filter. This can help you to judge correctly when carbon replacement is needed based upon the total volume of waste water that has been treated.

Water filters can also require special hazardous waste handling and disposal depending upon the type and concentration of the contaminant being removed. This can be more expensive than other water filters. A good example of this would be carbon filters used to remove radon in potable water. Establish beforehand how the handling and disposal will work or whether you require alternative treatment methods would be more effective in the long run. In other words, consider all options before you purchase any treatment equipment. Most importantly, make sure you opt to use activated carbon services where professionals handle and service your unit, reducing chances of any mishap.
