In the EU area, there are many sewage treatment plants which has
low treatment capacity due to aging. Eutrophication in many water
resources such as rivers and lakes is ongoing. And nitrate
pollution in groundwater resources is also serious. In order to
protect its public health and environment, EU has been
designating nitrate polluted areas (Nitrate Vulnerable Zones)
containing over N11.3mg/litter which is the limit for drinking
water on international water quality standards set up by WHO as
dangerously polluted areas by nitrate. (Huxham, 1999)
members, I would like to propose to renovate such old sewage
treatment plants and to reduce an amount of greenhouse gases with
the new technology to remove “Nitrogen" which causes
eutrophication without emission of greenhouse gas.
areas nearby the Ganges river in India do not have water plants
for suppling water and treating wastewater. Many people in these
areas do not have their own toilet due to their religion.
Population growth in these areas and pollution of the Ganges
river are heavily serious. And in these areas nearby the Ganges
river, there are many poor people using the river water for
bathing, drinking, and domestic purposes. In order to protect
their health, we have to clean up sporadic pollution resources in
these areas nearby the Ganges river. Cleaning of rivers in India
is a national accountability.
I would like to propose a
wastewater treatment project to remedy pollution on the Ganges
river areas without emission of greenhouse gas by the innovative
wastewater treatment technology with ESF provided by developed
countries. This project for environment and infrastructure may
establish a new company increasing many jobs in these areas.
In California state, there are warm and huge Sun Belt places with
insufficient water resources. How to divide such limited water
resources among agriculture, urban, and tourism industries is a
big social issue of California state.
I would like to purpose
effective utilization of the limited water resources in
California by reclaiming urban sewage water as water resources
for agricultural industries with the new advanced treatment
technology without emission of greenhouse gas which has been
A message from a wizard of
microorganisms; “Change old sewage treatment plants with the
of New Strategic de-nitrification treatment technology, and new
proposals transfer from us.
1976, Dr Jun Ui and me established Rural Environment Research
Association (“RERA”), a NGO specialized in environment, for
researching and developing a new waste water treatment technology
to resolve increasingly serious environmental problems. Since its
inception, RERA has developed the "Hybrid Lagoon System"
(“HLS”) and has put HLS into practical use in several areas.
is a latest advanced waste water treatment technology with an
activated sludge treatment and some high technologies. HLS
enhances treatment capacity of activated sludge more than other
waste water treatment technologies and even automatizes all of
such treatment. HLS gives an advanced waste water treatment
system high functionality and social cost benefit. HLS also gives
you a solution regarding waste water treatment in several areas
such as water recycling with advanced waste water treatment. HLS
is based on patents in the United States and Japan with lots of
90% of nitrogen, that is difficult to be removed from waste
water by other waste water treatment technologies,
of energy needed for advanced waste water treatment,
50% of surplus sludge produced with advanced waste water
requirements for the highest quality of waste water treatments
with some national regulations regarding waste water treatment
such as the Discharge standard of pollutants for municipal
wastewater treatment plant (GB/T 18918-2002),
environments of closed water system with improvement of polluted
sludge accreted in bottom of polluted lakes, and
used in areas of advanced treatment of organic waste water such
as municipal waste water and highly-polluted waste water.
Epidemic and Destitution are common issues for all people. In
order to tackle such issues, we requires latest advanced waste
water treatment technology with low burden to our society for our
our website, we would like to let you know our new technology
“HLS” as much as possible.
