What are the direct impacts of climate change on water reclamation?
Climate change risk to the water reuse sector can be divided into two categories: direct and indirect effects.
The influence of climatic conditions on technical performance is defined as direct impacts, whilst indirect impacts are primarily concerned with activities of management and operation.
Direct impacts of climate change on water reclamation:
1: Temperature
The impact of changing air temperatures caused by climate change on the wastewater reuse process has received little attention. The majority of them occurred in nations with high latitudes, where winter-related habits were investigated. In the winter, when the temperature is consistently high and there is snow on the ground, the influent flow rate exceeds the pumping capacity, putting the pumping stations at danger.
In fact, temperature is one of the control factors of the treatment process. Wastewater has a buffer capacity to tolerate mild fluctuated thermal arrays, temperatures exceeding or below the optimal range will affect the biological processes, especially with temperature-sensitive nitrifying bacteria.
2: Severe Weather and Sea Level Rise
Since the majority of wastewater collection networks can be gravity-based, treatment and reuse plants are frequently built in low-lying areas. Inundation, flooding, storm surges, erosion, and salt water intrusion are all threats associated with sea level rise. Flooding, hurricanes, storms, cyclones, and thunderstorms are projected to be more severe as a result of climate change. Warmer temperatures, less temperature variance between polar and equatorial latitudes, and higher humidity are predicted to amplify the intensity of extreme occurrences. Catastrophic catastrophes can completely destroy or partially destroy a wastewater reclamation system. Physical damages include:
(I) destruction of treatment facilities, pump stations, and sewer mains;
(II) interruption of treatment operations due to disruption of energy supply or leaking hazardous chemicals into the system; and
(III) plant shut-down or sewage discharge into the environment.
3: Precipitation
Increased rainfall intensity is one of the most common effects of climate change on wastewater reclamation. Although some cities have implemented separate sewage networks, the majority of metropolitan areas continue to use their old combined sewerage systems to transport both municipal wastewater and stormwater.
Infiltration through cracks, inadequately designed manholes, or even direct input may increase sewage flow in the conveyance system as a result of the enhanced rainfall regime. Heavy rain can impair the effectiveness of wastewater treatment processes by raising pollutant concentrations, floatable materials, and sediments in grit tanks or primary settling tanks. Bar screens and grit chambers have to be cleaned more frequently. Meanwhile, when wastewater is diluted with rain water and tainted by harmful compounds in roadway sediments, its properties change dramatically. As a result, changes in influent elements can influence biological processes such as activated sludge, nitrification/denitrification, and sludge floc formation.
