the proliferation of advanced wastewater reuse technologies. Despite the reuse of
water not being a new thing for some end users, more efforts will revolutionize the
water distribution and infrastructure. It could make water and wastewater treatment
to be more sustainable and cost-effective. Natural water sources are unavailable in
numerous arid and semi-arid areas. Thus, industry stakeholders will have to focus
on affordable options to augment the available water sources and halt events such
as groundwater salting and seawater intrusion. This could offer recycling solutions
to operations.
7.12 Summary
• Wastewater treatment has various phases that are crucial for ensuring that
wastewater is harmless to the environment.
• Preliminary treatment helps protect the pipes and systems against blockages.
• Waste removed can be grit, oil, grease, sludge, branches, trash, and other large
objects.
• The benefits of grit removal are a reduction of heavy deposits, reducing the
frequency of digester cleaning, and protection of mechanical equipment from
abrasion and wear.
• The main objective of primary treatment is to remove organic and inorganic
solids through sedimentation. Oil and grease are some of the products that can
be separated.
• Secondary treatment’s main objective is to further separate the waste in the waste
stream, including the suspended solids and residual organics.
• Sludge removal acts as the final process of ensuring that materials are separated
from wastewater.
• Tertiary wastewater treatment’s main objective is to increase water quality to
industrial and domestic standards, or meeting particular requirements governing
safe water discharge.
• Quaternary treatment is used for eliminating micropollutants in sewer water.
• Oil has been both a curse and a blessing for various entities, which was
highlighted by Saro-Wiwa in Nigeria.
• For Africa, future trends entail more demand for wastewater treatment and more
investment in research, while for North and South America, the major trends will
be reduced groundwater pumping, preparedness to boost resilience, and advanced
wastewater reuse technologies.
• Europe will mainly be characterized by higher demand for freshwater that
will drive the industry’s growth, and Asia will have many large-scale sweater
desalination plants.
• Urbanization and economic development will raise the demand for freshwater in
Australia.
