Explanatory Leaflet for SUMI-NAX
1. Aim of Development
SUMI-NAX has been developed for the purpose of making polluted water clean below theenvironmental standard value in Japan and reuse it, as an agent to flocculate, sediment and separate
solid substances from liquid in water*1:*1

Extraction of organic substances (Protein, Lipid, Carbohydrates, etc.) from polluted water
Extraction of inorganic substances (Heavy metals, etc.) from polluted water

2. Aggregation Theory
SUMI-NAX generates a strong flocculation effect with the following three synergy:1) Electrovalent bond2) Creation of complex salt3) Encapsulation effect on target substances
Following are the difference of the aggregation theories between other flocculating agents andSUMI-NAX:
1) The theory in Europe and America
Applying for hydrolysis function by the electric charge of the heavy metals such as aluminum, ironand magnesium.
2)

The theory of SUMI-NAX
Applying for hydrolysis function by the mineral electric charge instead of hydrolysis product ofaluminum. Taking in contaminated substances by a hydroxyl group.

3.

Features1)

Being a combination of compound substances
Both SUMI-NAX and other flocculating agents utilize the high electric charge in nature ofhydrolysis product.

While other flocculating agents hold the high electric charge with a single

substance, SUMI-NAX holds it with a combination of compound substances.
2)

Having a catalytic function
The compound substances contain mineral powder, which functions as a catalyst for flocculation
when the trace element in the mineral powder is eluted in water. Utilizing this function
enhances the effectiveness of flocculation.

3)

High-speed reaction
Mineral-related trace element works as oxidation catalyst. It changes water-soluble organicsubstances to water-insoluble organic substances and enables to gather substances quickly as
the deposition of solidification body. While other flocculation agents need about 10 to 30

minutes to completely flocculate substances, SUMI-NAX requires only about 2 minutes forcoagulating sedimentation substance and it makes continuous driving possible.
4)

Being suited for food waste liquid treatment
SUMI-NAX traps, flocculates and settles contaminants by the action of electric charge. At thesame time, it also acts for stable substance which does not have electric charge.
This is the application of “Dr. Funayama’s Theory.” Dr. Funayama called for his own theory thatneutrals are trapped by using hydroxyl group occurred under water. Using his theory made it
possible to treat food processing waste water containing a large quantity of neutrals such as
food waste liquids. Biological waste water treatment was the only method and any othertreatment method had been seemed impossible till then.

5)

Function of neutralizing water
SUMI-NAX has a nature of modifying both acidic contaminated drainage and alkaline
contaminated drainage to make neutral.
contaminated drainage is unnecessary.

Therefore, pre- and post-treatment to neutralize

This is also the unique feature that other flocculating

agents do not have.
6)

High dewaterability of generated sludge
Characteristics of flocculating agents in Europe and America:
・High density of generated sludge

・

Dewatering performance is insufficient due to the small size of glob of sludge

・The quantity of sludge generated is seemingly small・High transportation expense for the disposal of sludge containing large amount of water

Characteristics of SUMI-NAX:

4.

・Sludge dewatering equipment is unnecessary.

・The only process, Gravitational Dehydration, dewaters sludge easily.

・Low transportation expense for the disposal of sludge containing no water.

OthersCurrently, only the Japanese version of SDS is available.
