A method including receiving a parameter change relating to an operating environment that includes an adjustable washbox, and automatically reconfiguring at least one operating dimension of a media pathway defined by the adjustable washbox to handle the parameter change. A method including monitoring at least one parameter that relates to operation of a media bed filter, and automatically adjusting an operating dimension of a media path associated with the media bed filter responsive to a change in the at least one parameter.

Washbox

Exemplary systems and methods relating to washboxes are described.

The described implementations relate to water denitrification. One method obtains nitrate levels in influent and effluent of a moving bed media filter and determines carbon levels in the effluent. The method also doses carbon feedstock into the influent based on both the nitrate levels and the carbon levels.

Water denitrification

Exemplary systems and methods for treating contaminated water are described. In one instance a method supplies metal salt reagents to a moving media filter in the presence of contaminated water. The method also introduces a waste stream resulting from the moving media filter upstream of the moving media filter effective to lower an average contaminant concentration of effluent water from the moving media filter.

Water treatment method

Exemplary systems and techniques for treating contaminated water are described. In one instance a plant or system includes a membrane filtration mechanism operable to receive an influent water stream containing a contaminant and to separate at least a first portion of the contaminant from a resulting first effluent water stream. The system also includes a reactive filtration mechanism operable to receive the first effluent water stream and to remove a waste stream containing a second portion of the contaminant to produce a resultant second effluent stream.

Water treatment techniques

In one embodiment, a method for treating waste water includes passing ozonized waste water through a bed of moving sand.

Reactive filtration

In one embodiment, a reactive filtration method includes continuously regenerating a reactive filter media while simultaneously filtering contaminants from fluid flowing through the filter media. In one embodiment, regenerating the reactive filter media comprises mixing metal granules with the filter media and agitating the mixture. In another embodiment, regenerating the reactive filter media comprises introducing a metal in the fluid flowing through the filter media and agitating the filter media. In one embodiment, a method for removing phosphorus, arsenic or a heavy metal from water includes introducing a metal salt reagent into the water at a molar ratio of 5:1 to 200:1 to the phosphorous or the arsenic in the water and passing the water through a bed of moving sand.

Exemplary systems and methods relating to water treatment are described. One implementation filters water through a moving bed media filter sufficient to decrease the water's turbidity. This implementation simultaneously disinfects the filtered water and at least a portion of the moving bed media filter with ultra violet (UV) energy.
