Congress' use of the phrase "effluent limitation or other limitation" suggests that an "other limitation" must be similar in kind to an "effluent limitation": that is, a limitation related to the discharge of pollutants.
For starters, Congress' use of the phrase "effluent limitation or other limitation" in subparagraph (E) suggests that an "other limitation" must be similar in kind to an "effluent limitation": that is, a limitation related to the discharge of pollutants.
The relatively high values for nitrate obtained for some groundwater samples (GW 1, GW 2, GW 3, GW 6, GW 10 and GW 12) are attributed to application of nitrogen fertilizer in the cultivation of crop plants and irrigation of the farmland by the use of sewage effluent and poor quality surface water runoff and infiltration into the groundwater system, especially the shallow hand dug wells.
The simple biodigester technology had been developed and refined at CIPAV and the principle of using the effluent as a fertilizer for ponds and also in the production of earthworms for compost and/or feed had also been applied.
Consequently, downstream uses of this effluent, whether to maintain streamflow and quality, groundwater recharge, or irrigation may be impacted.
However, continued advances in micro-irrigation system design, management, monitoring, and especially in water treatment have expanded the use of biological effluent through micro-irrigation systems.
These findings suggested that the use of sewage effluent in irrigating T. speciosa seedlings grown in calcareous soil was beneficial for the improvement of soil properties and production of timber trees, and also important for the safe manner of disposal of wastewater.
The use of the high temperature SCWO effluent for energy purposes has been studied in the literature.
Nowadays, due to the increasing presence of molecules, refractory to the microorganisms in the wastewater streams, the conventional biological methods cannot be used for complete treatment of the effluent and hence, introduction of newer technologies to degrade these refractory molecules into smaller molecules, which can be further oxidized by biological methods, has become imperative.
In order to evaluate the biological degradation capacity of this novel constructed immobilization system, the immobilized pellets were applied to treat paper mill effluent and decolorize dye Azure B. The use of the constructed immobilization system in the effluent resulted in successful and rapid biodegradation of numerous insoluble fine fibers.
