Underground Filter Beds

When dimensioning an underground filter, in addition to the calculation of the required quantity of GEH 1010, as well as the hydraulic load of the system, also information about the geological situation is required. The adsorption capacity depends on the water parameters and operating conditions. A specialised planner should be involved fro the dimensioning and design.

Transport & Storage

The product is stable and can be stored for at least one year. To prevent the material from drying out, the big bags should be closed and, if possible, not stored outdoors. Outdoor storage is possible in plastic bags or protected from direct sunlight and at moderate temperatures (0 – 25 degrees Celsius). The big bags must not be stacked.

Individual Application Advice

Every application in water treatment has its own special requirements. A meaningful dimensioning of the plant and definition of the operating conditions can only be made after examining the individual case. The recommendations contained in this page are therefore legally not binding.
