BIODIGESTER TECHNOLOGY
THE ENVIRONMENTALLY FRIENDLY WAY TO TREAT WASTE
The activities of the Scientific Research
Council (SRC) will soon make Septic Tanks and Soak-away
Pits, which can cause pollution to the environment,
a thing of the past. It achieves this through the application
of anaerobic technology.
Anaerobic technology
is the process of treating wastewater without using
oxygen. Many countries in Europe and Latin America utilize
this technology, which treats wastewater in an environmentally
friendly manner, facilitating its use for irrigation
or its return to water bodies without polluting them.
The process also generates organic fertilizer and biogas
(a form of fuel) by allowing naturally occurring bacteria
to break down solid waste. The Biodigester System operates
on the principles of anaerobic technology, and is used
to treat organic farm waste. Another variant, the Biodigester
Septic Tank (BST) is an on-site sanitation unit
that utilizes anaerobic technology for the disposal
of toilet (black) wastewater as well as of kitchen and
bathroom (grey) water, in a closed system. The SRC currently
applies this technology instead of septic tanks and
absorption pits on several farms, housing complexes
and single households to treat animal waste and domestic
sewage.
Many communities, farms, organizations
and institutions have benefited from Scientific and
Technological solutions as the SRC works with them to
develop environmentally friendly waste management systems.
The SRC has assisted with the development and implementation
of a Biodigester System in Western Kingston. The system
treats solid waste - banana skin; and liquid waste –
sewage; to generate biogas and organic fertilizer at
a local chip factory in the community. The organic fertilizer
(treated solid waste) will be utilized by the factory
and/or sold to small farmers as soil conditioners. The
John Bascoe Boys’ Home in Hatfield, Manchester,
is another example of the successful application of
Biodigester Technology. At this Boy’s Home, food
crops are produced from treated organic waste, treated
wastewater used for irrigation and biogas used to cook
meals and for other energy related purposes.
There are many benefits to be derived
from the use of anaerobic technology. The Method is
simple in construction and operation, and consequently
inexpensive. Biogas Projects should aid in the reduction
of fuel cost, as it is more cost effective to use biogas
than Liquid Petroleum Gas (LPG) as fuel.
The Need for Biodigester Septic
Tanks?
- The discharge of untreated
wastewater on economically important natural resources
such as rivers and seas, and their ecosystems leads
to their destruction.
- The inadequate handling and
disposal of sewage lead to health problems.
- Household sewage generated is
causing serious pollution of surface and ground waters.
- The present ‘on-site’
systems of sewage disposal do not provide much in
the way of treatment
- The extremely high cost of high
tech systems (activated sludge, oxidation ditches
etc.)
- The use of the generated biogas
which can be used in place of LPG and firewood
- The need for alternative energy
sources
Let
us help you to 'turn your trash into cash' through
our waste management programme. Prevent waste! Reuse
and Recycle your waste without harming the environment.
Let us help you
to reduce your operational cost through
waste management. We can design
wastewater treatment systems, that utilizes the principle
of anaerobic technology. We can build biodigesters
that will utilize your domestic and commercial waste
to generate biogas - an alternative source of fuel,
which is cheaper than liquid petroleum gas (LPG).
