Activated Carbon filtration is widely used for reducing dissolved organic compounds, taste, odor, and other contaminants through adsorption. While the quality and type of carbon are important, the amount of time water remains in contact with the carbon bed also has a major influence on treatment performance. This time is commonly described as Empty Bed […]

Filter Media Sand can remain in a filtration system for a long time when it is correctly selected, operated, and maintained. However, continuous filtration, backwashing, solids loading, and gradual media loss can eventually affect the condition and performance of the sand bed. The important question is not simply how old the sand is. Filter Media […]

Filter media can provide reliable filtration for a long period, but its performance depends heavily on proper operation and maintenance. Sand, anthracite, gravel, and other granular media continuously interact with incoming water, suspended solids, flow, and backwashing conditions. Without appropriate maintenance, accumulated solids can increase head loss, disturb the media bed, and reduce filtration efficiency. […]
