摘要:
The present technology relates generally to fluid filtration systems. In particular, several embodiments are directed toward compartmentally expandable rotating belt filters and associated systems and methods. In some embodiments, for example, a filtering system for contaminated fluid includes a first fluid filtering chamber having a first filter belt movably positioned therein and a second fluid filtering chamber having a second filter belt movably positioned therein. The first filter belt can be operable in parallel with the second filter belt. The system can further include a sensor configured to sense a condition related a volume of the contaminated fluid, a speed of flow of the contaminated fluid, or a level of contaminants in the contaminated fluid. A controller can be configured to initiate, stop, or adjust fluid flow to the first fluid filtering chamber and second fluid filtering chamber individually in response to the sensed condition.

The present technology is directed generally to media reconditioning and/or recovery systems for use in fluid filtration. In some embodiments, a reconditioning system includes an additive source configured to inject an additive into a fluid filtration chamber for media reconditioning. In several embodiments, a controller controls the timing, sequence, amount, and/or duration of additive injection. The additive can be selected to achieve a desired filtration outcome. In some embodiments, the system further includes a recovery component configured to redirect and capture the filtered media.
摘要:
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.
