Japan Thread is an environmental consulting company with a head office in Minato-ku,
Tokyo, established in 2009 to plan, propose, and sell low-cost, safe water treatment
technologies (water purifiers and flocculants) developed by Reterra, an affiliatedcompany.
Japan Thread is a total distributor of thread filtration systems for municipal
governments, and also we also plan other new products for the environmental sector. AsJapan Thread is a fabless company, these new products are outsourced for
manufacturing. In 2006, the thread purification system (made in Israel) was awarded
the Certification of Water Treatment Equipment from the Japan Water Research Centerand has since been adopted by 6 waterworks bureaus across Japan.
We are looking to collaborate with other enterprises to increase sales of our thread
filtration system, which we have experience selling to both the public and private
sectors in Japan.
Our Double Clean Filtration System is still in the development stage, but we arelooking to partner with other enterprises from the current stage and develop newmarkets. In particular, we are looking to target foreign markets with both our Double
Clean Filtration System and SUMI-NAX.
We are also interested in sewer and water supply systems and wastewater treatment
projects in Vietnam, Indonesia, Mongolia for JICA's "Feasibility Survey with thePrivate Sector for Utilizing Japanese Technologies in ODA Projects" and "Verification
Survey with the Private Sector for Disseminating Japanese Technologies." We arelooking for companies who would like to do business using our flocculating agents andwater purification systems.
Japan Thread has certain strengths as a startup company and we are ready andwilling to take on new challenges, so won't you work with us on a project to benefit
others?

Overview of Product/Technology

Product/ Technology Double Clean Filtration System

Characteristics

This unique filtration system is being developed utilizing four natural phenomena andutilizes newly-developed wound thread filters, which can withstand backwashing. This
module is proficient at pretreatment and works with high flux and accuracy. The threadwound filters (nominal openings of 2.0 ㎛) are durable and lower the running cost.
The immersion-type filtration is well-suited for treating wastewater (sewage), drainwater, and ballast water.

Keywords

The spiral guides built into the inner wall of the modules creates a whirlpool. Passing
through the filters installed inside the module, even water with a high turbidity can bepurified.

Price
Details

Size of 1 module 750 mm × 70 mm; size of 10 modules (1 unit) 120 mm × 1500 mm ×950 mm; filtration volume (1 module) 10 m3/day (in the case of purified water); module+ a control panel, pumps, solenoid valves, and a pressure tank are needed

Capabilities

Filtration capacity: starting at 10 m3/day per module. Modules can be added, making
the potential capacity limitless; Filter micron rating: thread woven filter: 0.5 ㎛-2.0 ㎛;
nonwoven fabric filter: 2.0 ㎛ or more

Cost

In addition to the cost of the unit: delivery fee, test-run/adjustment fee, technical guidance fee

Product/ Technology Thread filtration system (MTG-JW, MT44P-JW, MT22P-JW)

Characteristics

Keywords
Price

This filtration system is capable of removing chlorine-resistant pathogenic
microorganisms, such as Cryptosporidium. The high-pressure washing function
removes sedimentation from thread wound filters, which allows them to be continuallyused, rather than being used disposably, as is typical with filtration systems. Based onpressure detectors, jets are activated to wash away impurities and then return to thefiltration process. This high-efficiency filtration system can purify water in 12 minutes.
The running costs is low, as filter media needs to be replaced only once every eight
years (depending on the quality of the raw water).
Although Israel isn't known for making thread water filtration systems, the country's
military and water processing technologies are famous. By developing sprinkler anddrip irrigation technology, the country overcame its lack of water to develop its
agriculture industry.

SUMI-NAX inorganic flocculating agent

Characteristics

SUMI-NAX has a large electric charge as it is a mixture of 10 types of inorganic
compounds. As it is made from inorganic compounds and does not harm the human body,there is no need for worry about its effects on the human body. Its reaction is fast and thefloccules do not easily break up, so they can be dehydrated by centrifugal separator or sun
drying, which allows the amount of waste to be reduced.

Keywords

Within 2 minutes of adding SUMI-NAX to raw water, flocculation begins. The ideal pHof water to be treated is 5-7, but flocculation still occurs outside of that range.
It is effective for the pretreatment of high turbidity water, such as is found in rivers andlakes throughout the world and wastewater treatment.

Price350 yen/kg (delivered from the factory in Yantai, China; if incremental taxes, min. order of 20 t)

Details

It has a large electric charge from the inorganic compounds, and as the catalyst is fineparticles, it even has an effect on dissolved solids to a certain extent. By using thehydroxyl group, it is even effective on substances without an electrical charge.
