If
you are looking for key information on sewage treatment plants, you should know
about the 2 major types of systems used by STP plant manufacturers India to
treat sewage. These are aerobic and anaerobic systems. Each treatment is meant
for different purposes and has pros and cons. In this article, manufacturers of
STPs will discuss about Aerobic treatment in detail.
Aerobic treatment for sewage
Aerobic sewage
treatment is a process in which bacteria use oxygen to degrade pollutants and
organic matter involved in various production systems. The two common types of
aerated waste water systems are activated sludge systems and aerated
stabilization basins. The aerated stabilization basins (ASBs) are widely used
as treatment systems in the pulp and paper industry and are also used in some
industries and municipalities.
There are eight
growth pressures that put impact on the treatment system. However, in this
post, we will talk about the two major pressures, i.e. oxygen and organic
loading. In a general model of wastewater treatment system, the influent
entering to the system has the most biochemical oxygen demand as it is
untreated. Since the influent reaches the ASB, it makes entry to the aerated
environment, which is a starting point of degradation.
Distinct types
of aeration are used in ASBs but the widely used are either surface aerators or
diffused aeration systems. In case you are using surface aeration, multiple
units are required to be properly spaced in order to treat the water. Diffused
aeration is normal air supplied through blowers or compressors and piped under
the surface. Air is released evenly under the surface throughout the ASB. Occasionally,
manufacturers and engineers use pure oxygen in wastewater treatment; however,
it is uncommon in ASBs.
The biochemical
oxygen demand degradation is achieved through aerobic bacteria in a system. The
bacteria present in sewage use oxygen as an electron receptor in order to
transform the organic material to carbon dioxide. This entire process helps
bacteria to multiply and create more bugs to break down more biochemical oxygen
demand.
Whatever the
type of treatment used by the industries, each of the treatment systems has its
place in the world today. Being different in the process, both the treatments
are used to achieve maximum degradation, while taking care of standards and
regulations set by the environmental agencies.
