Water revitalization project in Malaysia

Melaka River, Malaysia
(Malaysian national project using total 240 t of EBB)
Lab test at ALS Technichem, by Dr. Chin Teen Teen used Damansara river water with the following proven results:

  • BOD: from 11 to 8 mg/l
  • COD: from 31 to 21 mg/l
  • TSS: from 88 to 40 mg/l
  • NH3N: from 4.53 to 3.86 mg/l
  • Turbidity: from 91.3 to 35.2 NTU

Setaka-town, Fukuoka, Japan

Easy-to-install. No major construction or electricity is required with the following proven results:

  • BOD: from 2.5 to 0.7 mg/l after 14 days
  • COD: from 8.3 to 4.7 mg/l after 14 days
  • TSS: from 110 to 5 mg/l after 14 days
  • E-Coli: from 7.9 to 1.3 mpn/100ml after 14 days
  • Phosphor: 0.34 to 0.041 mg/l after 14 days
  • Turbidity: from 31 to 2.8 NTU after 14 days


Purify aquaculture ecosystems and greatly minimize maintenance

Conditioning products that clean water and remove sludge from aquaculture applications.


july 2015

This is a tidal flat with a sludge depth of about 20–40cm. This picture shows the beginning of the Nagasu-cho Coast Test in Kumamoto Prefecture, where no shellfish exist.

Installation area: 2000 sq. meters
Number of bags used: 53
Mud friction: 30% or more

Installation begins

July 2015

Surface sludge removed

August 2015


August 2015

The water temperature is more than 25°C, reaction rate is good, and  sludge on the surface is removed, exposing shells below.There are no shellfish living there yet.


October 2016

Surface sludge is further removed and shells become more exposed. There are still few short neck clams (Asari).

Exposed shells below

Suitable conditions for habitation

January 2016


January 2016

Young short neck clams appear and begin to be measured. The shell length is about 5 mm. 1250 clams per square meter.

The sludge is removed relatively quickly. Analysis of the sludge reveals that the organic component are diatoms which is a food source for fish and shellfish.

At this time, it was also determied that the percentage of mud was reduced to less than 10% (suitable for the habitation of Japanese littleneck clams)


With the success of the Ariake Sea experiment, installation has begun in Tokyo Bay, Awaji-shima Island and the Seto Inland Sea.
