Indiscriminate disposal of arsenic waste from the arsenic removal filters is a common practice in many underdeveloped countries. Improper disposal of arsenic waste on the ground surface and subsurface from the arsenic removal filters and treatment units of any filter media causes numerous environmental problems. These include air pollution, contamination of soil and sediments, surface and groundwater resources, aquatic organisms such as fishes, poultry products, agricultural products and thus pollute the entire public health, ecosystem and environment. Therefore, filter users should be aware of these problems and take necessary steps for proper disposal of the arsenic waste.
Humane Water has developed two types of arsenic waste disposal methods for protecting the public health, ecosystem and environment in underdeveloped nations:
- The waste from the “Non-electricity based Mukti Water Treatment Systems” is reduced by recycling and reuse the filter media. The waste is then solidified with good quality of cement and disposed into a concrete vault.
- The waste from the “Electricity based Mukti water treatment Systems” can be disposed either into an arsenic waste disposal well or into a concrete vault. Both methods are very effective and safe.
These methods were developed based on US EPA arsenic waste disposal regulations, geological, climatological and socio-economic conditions of underdeveloped nations.
