Abstract :
The Municipal waste water treatment plants
to be built in developing countries are expensive and
their maintenance cost is high. The cost of treatment has
to be low to refine the waste water. The waste water
treatment plants require huge area and also the
advanced equipment including human labor in handling
of the same. In both advanced and developing nations, at
least centralized waste water treatment plant will not
always fulfil to meet the requirement for the continuous
future demands that has to be sustainable. The domestic
demand for water could be reduced by building
Decentralized system that treat sullage for the reuse of
the water to gardening purpose as the minimum usage.
These smaller unit’s help in reducing the Biochemical
Oxygen Demand of water and chemical Demand of
water hence the load on the main treatment plant can be
decreased. Individual treatment plants will not have the
difficulty in disposing of the sludge which pose a
challenge when the waste water is chemically treated.
The waste water treatment plants producing higher
amount of sludge is challenge to disposing of
environment, transportation, finances and space for
storing.
The methods available for the treatment of waste
water are mechanical, physical and chemical methods.
The treatment of wastewater, sludge reduction and
stabilization also includes ultrasonic, thermal and ozone
pre-treatment. The capital requirement and the
operational cost and some drawback suffer. However,
the technical challenges to operate with skilled and
unskilled labour also suffers in effective functioning. Bio
engineering technologies based on these raw materials
are promoting, regulating, improving and enhancing
their self by including the technologies that does not
require energy and waste will not be produced. Such
units are built easily, maintained and operated with less
difficulties. Low or no-energy requiring zero-waste
technologies, easy to construct, operate and maintain.
The organics are utilized by these technologies with
increased activity in conversion to energy, also helps in
the exceling conversion of complex organics to simple
matter. The organics that otherwise will create problems
of foul smell, insect breeding and will not be utilized for
other purposes. The reduction of the bio solids could be
achieved well in this technology rather than others.
