1. Introduction
The MLIT launched the "Breakthrough by Dynamic
Approach in Sewage High Technology" (B-DASH)
project in fiscal 2011, and the Water Quality Control
Department of the NILIM serves as an executing agencyof this project.
We have, therefore, drafted guidelines for sewerage
service providers to consider the introduction ofinnovative technology based on the results of ourempirical studies and the evaluation by the B-DASH
Project Evaluation Committee with regard to twotechnologies adopted in fiscal 2011 for water treatment(solid-liquid separation) and biogas recovery / refining /electricity generation in sewage treatment facilities.
2. Outline of biogas utilization technology(1) Energy management system using intensive
solid-liquid separation technology
This technology represents a technical system thatgenerates electric power via a hybrid fuel cell by fullyusing biogas obtained from the digestion of raw sludge,of which collection is increased by upgrading solid-liquid
separation using a carrier.
(2) Effective renewable energy production
system utilizing biogas
This technology represents a technical system for using
renewable energy for automotive fuel, etc. This is done
through a series of processes for increasing the collectionof biogas from local sources such as food, increasing theeffective usage of the biogas by heating a sludge
digestion tank made of steel, and purifying the biogas tohigh degree of quality with a packaged biogas upgrading
system.
3. Outline of the technology introduction
guidelines
The Table shows the content of the guidelines (draft).
Chapters 1 and 2 describe the objectives and outline thetechnology. Chapter 3 estimates the effect of thetechnology when introduced in a treatment facility.
Based on the results of estimations, the possibility ofintroduction is discussed. Chapter 4 examines basicplanning, equipment design, etc. for introducing thetechnology. Chapter 5 describes check items andfrequency that will be required when the technology isintroduced.

4. Utilizationoffindings
andfuturedevelopment
In order to introduce these guidelines to the concerned
persons in local governments and businesses, apresentation was held at the Tokyo Big Sight on August 2,(Fri.) 2013.
By holding similar presentations, we will continue toconstructively introduce these guidelines to concerned
persons and to disseminate the technology.
