There are many types of sewage treatment plants available because a standard type would not suit the requirement of different companies.

1. Types of Sewage Treatment Plants
Waste generation is almost like a routine in our day-to-day lives. Household waste
which includes garbage or sewage waste that is collected in septic tanks needs to
be managed tactfully to minimize the impact on the environment. In many
countries, it is a mandatory government requirement for big enterprises to install
an STP plant.
There are many types of sewage treatment plants available because a standard
type would not suit the requirement of different companies. Some common
distinguishing parameters are space requirement, cost constraints, technology
preference, etc. Before Look at types of sewage treatment plant, let’s know
actually what is sewage treatment?
What is Sewage Treatment?
Sewage treatment is a solution or system in which the waste water is treated to
make it ready for reuse. To treat the waste water it requires many processes which
are stated under:
Sewage water is kept in a tank for many days without any kind of disturbance so
that hard sludge or sewage can settle down and other wastes for water like oil and
grease can come up on water in a tank.

2. Then Oil and grease are removed carefully and then they would be processed of
further detoxified so that they can be used to make detergents, soaps, etc. And the
process to make soaps and more is called saponification.
Then the water is bifurcated into two different tanks. The water of one tank is used
for the irrigational method and water from another tank is treated further to be
more cleaned.
The final tank of water is treated with scientific and latest technics so that cleaned
water can be used for various purpose
Let’s look at some common types of sewage treatment plants.
Package Type: This plant can be transported on site in packages and then installed
by trained staff members with minimal effort. It is a medium-capacity sewage
treatment plant and therefore is suitable for standard complexes. It can make use
of moving bed, sequential, or membrane bioreactor. This can be transported easily
to the facility where it needs to be installed because colossal parts are not
involved.
Civil Type: This type is appropriate for large complexes because it has high
capacity. For installing a civil type sewage treatment plant, on-site assembling and
installation are required. The parts can be transported but the majority of the work
needs to be done on site. The advantage for opting for this type of STP plant is
that it requires minimum advantage which is a must for large-scale sewage
management.

3. Container Type: This type of sewage treatment plant has all installation within a
container and that is where it derives its name from. Because of pre-fitted
mechanism, this just requires an on-site setting and then it can be fully
operational. This type of STP plant is easy to carry and install. This is ideal for
enterprises that have mobile like camps or for customer-oriented set-ups like
hospitality industry where mounting a large sewage treatment plant can cause
trouble to customers.
Compact Modular Type: This is the smallest type of sewage treatment plant
available and is suitable for small individual residences or commercial outlets. It
requires minimum effort to assemble this type of sewage treatment plant.
Although this is compact in size, it does not mean that this works anything less
than a full-fledged plant. This is as good as other bigger options. It is just the
capacity that differentiates this from the other types.
As a commercial complex owner or a residential user, you might want to use the
treated water from these sewage treatment plants differently. For example, the
water can be used for irrigation if that suits you or for flushing at almost all the
outlets. When you select a sewage treatment plant manufacturer, be sure to discuss
your specific requirement with them. You would be required to share details
regarding the nature of waste, a number of people in your enterprise, space
available to fit the STP plant, etc. And all of these details will help the
manufacturer guide you to choose the best plant so that the desired output is
achieved with minimal investment.
