Effective Wastewater Treatment ProcessThe key objective of wastewater treatment is to ensure human and commercial waste is disposed without any hazard to the population/environment. Managing agriculture using wastewater (after treatment) can be looked at as both disposal and utilization. The waste water quality has a bearing on productivity of wastewater land. Again, the quality of waste water required depends on the cropping pattern, the nature of soil and the procedure for effluent management. Based on an efficient selection of crops and irrigation method, health risk can be reduced. However, the same process cannot be followed for aquaculture systems.
The effective wastewater treatment to be considered for effluent utilization in agriculture is one adhering to the established microbiological and chemical quality guidelines (low cost and less operational/maintenance needs). The adoption of a low level of treatment is particularly critical in less developed nations due to the cost factor and complexity of operating systems. It would be appropriate to develop a reuse system catering to low-grade of effluent instead of depending on top notch treatment processes. However, certain places require an efficient effluent and therefore it would be prudent to provide information on an entire gamut of wastewater treatment technology.
The development of wastewater treatment plants would be based on the requirement to decrease organic and suspended solids loads to negate environmental pollution. The eradication of pathogen may not be given due importance, but from a perspective of reuse for agriculture it becomes vital. However, the technology for eradicating wastewater particles is not cost effective. At present, less data on wastewater treatment plants in developing nations exist. The variations in the short run in waste water flows existing at civic wastewater treatment plants adhere to a diurnal method.
The flow is less in the morning season, when water consumption is lowest. The water flow peaks during late morning, while it peaks again in the evening. The magnitude of the peaks and their frequency differ from one nation to another. Though the gravity of peaks is enhanced as wastewater flows through a treatment plant. Communities with fewer members and small sewer systems have a greater ratio of peak flow in comparison to bigger communities. Even though the intensity of peaks is enhanced as wastewater flows though a treatment plant, the fluctuations in flow on a daily basis from a municipal treatment plant make it unviable to conduct agriculture using effluent from the treatment plant. The availability of flow equalization/storage in the short run of treated effluent is needed to deliver a regular supply of restored water for efficient irrigation.
