Difference between Sand Filters and Carbon Filters

Sand Filters and Carbon Filters both work for the purpose of removing harmful particles from water, but they function differently. Sand filters are one of the critical components in the process of water treatment. Sand filters, as the name suggests, work by filtering out water using sand. The water to be purified is made to slowly pass through the sand and dirt particles get extracted by the fine pores of the sand. Sand filter technology also has a widespread application in groundwater cleaning, rinse water processes, re-circulating systems, irrigation systems, etc.

What is Sand Filter?

A Sand Filter is one of the important parts of any water filtration system. A sand filter, as the name suggests, is a filter that is filled with sand. A combination of sand is used with different particle sizes. The sand filter size will depend on the flow rate of the liquid. Sand filters are usually placed in starting of the water filtration process, and are followed by activated carbon filters. 

What is Carbon Filter?

Carbon Filters play a very crucial role in the process of water purification. The Carbon filters remove chlorine, volatile organic compounds, odors, and unpleasant tastes from water. They contain activated carbon as the filter media which is extremely porous and have a large surface area. Impurities get absorbed into the activated carbon upon passing through; heavy metals are removed once they make contact with this filter material. The water that leaves is much cleaner.

What is the difference between a Sand Filter and Carbon Filter?

Sand filters and Carbon filters are quite different from each although similar in construction. The most important difference is that the media used in carbon filters is a large layer of activated carbon.

Carbon filters are very efficient in removing residual chlorine that did not get removed in the previous stage of filtration by a sand filter. Carbon Filters are also quite effective in removing molecular organic particles or elements that have escaped filtration in the previous stages. It also eliminates any odor, color, pesticides, and even several organic components that might be present in the water.

Carbon filters are usually placed after sand filters. Carbon filters also need maintenance for their efficient working just as sand filters do.

The life span and efficiency of activated carbon filters are affected by some factors such as the composition and concentration of pollutants, the duration of airflow in the filter, and the temperature of the water and humidity.

How does a Sand Filter work?

A Sand Filter is attached where the water comes into the system. The sand filter’s operation is quite simple and very efficient. Water gradually passes through a filter that contains sand of different particle sizes. The sand filter composition is dependent on the kind of impurities that need to be filtered out.

The filtered particles get accumulated in the outer layers of the filter. To keep the sand filter from getting clogged with filtered-out impurities, the sand filter is to be back-washed. The back washing is done by reversing the direction of the flow of water which cleans off all impurities and the sand filter can be reused for further filtration processes.

Benefits of using a Sand Filter

There are several benefits of a sand filter -

• Sand Filters can easily remove visible and suspended impurities such as dirt, silt, and sand.

• Sand Filter price is very cost-effective.

• The sand filter also reduces the turbidity and TSS of the water.

• It is also very easy to maintain and operate.

• Sand filtration is useful in improving the quality of water by removing ammonia, deferrization, and demagnetization.

Conclusion

Sand filters are better for removing larger particles such as dirt, sand, etc while carbon filters are better for removing organic compounds and chemicals. Sand filters and Carbon filters both are crucial parts of the water treatment system. Both filters have different advantages over each other such as Sand filters being less expensive and simpler to maintain but not as effective in removing certain types of contaminants like chlorine, chemicals, etc that carbon filters can remove.
