We, Rural Environment Research Association (RERA) is a NGO for solving environmental problems. The RERA was founded by Hiroshi KISHI and JUN UI in 1975. Since then, we have been managing RERA over 30 years. 

RERA has developed the "Hybrid lagoon automatic control system," a low-cost, high-function wastewater treatment system. The system can remove nitrogen in water. For example, city sewage can be recycled for agricultural industries by using the system including a process of removal of nitrogen. The technology has been applied in patent fillings (PCT WP2005/0708038, US 10/586.889). 

On the other, removing nitrate nitrogen contained in ordinal underground water is also possible and makes the water containing nitrogen safe drinking water. The biological treatment of the system can change polluted water to safe water for supply. With the system, it is possible to establish a new type of circulation for enterprises for environment protection. 

We called the Homepage as a "Homepage to transfer our technology to overseas." We believe that problems of environment protection is much popularized in the earth and  the system becomes a way to resolve many problems in many areas.

This Homepage contains some proposals with technological comments of next three-category and earth environment protection,

1. "Irrigation plan" for city sewage with denitrificated water,
2. "High wastewater treatment plan" with an open-air pond without timbering and high-level technologies,
3. "Organic pollution removal plan" for water services.

We have studied and developed treatment technologies as follows.

1. Simplifying a structure for lower construction cost,
     "Our system costs less than a half (1/2) of standard types of facilities with activated sludge treatment."
2. Developing high-performance dentrification of sewage for recycling water for agricultural use,
     "Our system achieves a quality of treated water under 5mg/l of T-N in year ."
3. Saving oil for energy used for water treatment,
     "Our system needs less than 0.3 kW/h of electroenergy per cubicmeter for high treatment of sewage".
4. Inspecting a theory for automatic control of denitrification by microbe,
     "We secure the water that always become stable even in easily changing situation of a quantity of sewage water, density and temperature."
5. Improving harmful bottom mud by a transition technology of microbe.

It is not easy to transfer new technology to some different geographical conditions, languages, and cultures.

We think that education for a long time and social capital to transfer environmental protection system are needed. In particular, following items are needed,
  1:  Preparation to accept the system and organizations for it,, 
  2:  Conservation of intellectual properties for environmental protection.

RERA, introduces some technology documents necessary for technology transfer, and there are to prepare the technical education, enterprise investigation, planning, design, supervision, maintenance management lesson, and cooperation for study.

RERA hopes that our information in the Homepage will help you for environmental protection in your country.
