As a leading company in Japan having the top market share of salt, Nihon kaisui Co.,Ltd has been delivering secure and safe salt to everyone for many years. Based on
our spirit of " technological potentials” and " traditions of craftsmanship" developed
through the production of salt as ocean's bounty, we engage in environment, foods
and agricultural business by exploiting infinite seawater resource.
Business
The products of the Environment Division include: 1) magnesium hydroxide slurry
Activities
used for desulfurization/neutralization of coal power plants, 2) the adsorbent READ
series to remove arsenic, fluorine and boron which are often technically difficult toremove, 3) ozone treatment facility using nanobubbles capable of treating hardly
decomposable organic matter.

Message/
Other

Although we have abundant track record in Japan for the sales of the hazardous
substance adsorbent, our business operation has just begun to overseas. We are
seeking collaborators who have business interests in water business in Southeast
Asia.

Management
NumberArsenic in water can be continuously removed to achieve the Japan’senvironmental standard at 0.01 mg / L by using adsorption tower packed with
the Adsorbent.
The frequency of regeneration cycle depends on concentration and water flowrate.

Capabilities

The basic adsorbent volume is proportional to water volume treated per hourdivided by 10

Cost

Installation of adsorption tower is necessary in addition to the adsorbent.

Life cycle
Remarks

Normally it needs replacement every 7 years
In operating regeneration business, a base in the field is necessary.

Fluorine in water can be continuously removed by using adsorption towerpacked with the Adsorbent.
Reusable by alkaline cleansing to remove fluoride.
The frequency of regeneration cycle depends on concentration and water flowrate.
The basic adsorbent volume is proportional to water volume treated per hourdivided by 20

Installation of adsorption tower and regeneration unit are necessary in addition
to the adsorbent.
Normally it needs replacement of 10 to 20 % of the adsorbent /annum
Application of the adsorbent to high concentration wastewater causes notefficiency due to adsorption capacity of the material.
