The provided diagram demonstrates how wastewater is converted to clean water. Ryg9o
The provided diagram demonstrates how wastewater is converted to clean water. Generally, the process consists of 18 main phases, including waste separation, solids removal, and sanitation of water. In the beginning, waste from the sewage system is placed on a platform, where the waste is screened into two distinct types of waste: physical and liquid. The waste products are transported to landfills, while the wastewater drips down to a pump-managing machine, which sends the water to a container. Inside the container, all the sand and grit are completely removed before the water flows to consecutive tanks. In the next 5 steps, solid matters sink to the bottom of the containers, some of which are consumed by bugs, while others are biologically processed. It is also worth noting that sludge being extracted can sometimes return to the previous tank. Once the water goes through these tanks, it is sent to another pump control that leads to a sand filter for particle elimination. Afterward, the liquid is combined with bleach to destroy bacteria, then the phase is reversed so that pure water can enter the natural rivers. As for solid waste, it is divided into 2 categories (heavy and light waste) before being crushed together. Subsequently, the concoction is dehumidified and mixed with lime for disinfection purposes. Finally, the cleansed matter becomes compost that is used to grow inedible agricultural products.

In the beginning,
waste
from the sewage system
is placed
on a platform, where the
waste
is screened

waste
: physical and liquid. The
waste
products
are transported
to landfills, while the wastewater drips down to a pump-managing machine, which

before
the

5 steps, solid matters sink to the bottom of the containers,
some
of which
are consumed
by bugs, while others are

processed. It is

Once the
water
goes through these tanks, it is
