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.
- 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.
- 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.
