Business Activities – NDB CORPORATION LTD.

NDB’s Business

We pursue value creation and dream-inspiring businesses that support “water environment and lifestyles”.

Water treatment related products

　With a mission to clean water, NDB started selling air pumps exclusively for wastewater treatment systems to overseas customers after its establishment in 2014, and since then has also been engaged in import/export of water treatment-related commercial products such as valves, diffusers, and filters.

**Valves for air adjustment, fine airflow, distribution adjustment, etc.**
This valve can “pass, close, and adjust air,” “distribute air in two directions,” and “adjust low air volume” by adjusting the handle position.

**Diffusers**
In biological reaction tanks such as aeration tanks and contact aeration tanks, oxygen is supplied to the biological film attached to the activated sludge and contact materials, and the inside of the layer is mixed and agitated to produce ultrafine, fine, and coarse air bubbles.

**Handling of water treatment related commercial products**
Please feel free to contact us if you have any inquiries about water treatment related products that are wastewater treament systems. We have sold air pumps exclusively for wastewater treatment systems in the past and have strong relationships with septic tank-related manufacturers.

Neodymium magnet

　Rare earth magnets are permanent magnets made from rare earth elements, also known as rare earth magnets. The two main types in practical use are neodymium magnets (Nd-Fe-B) and samarium cobalt magnets (Sm-Co). Neodymium magnets (mainly composed of neodymium, iron, and boron) are the strongest magnets on the market today, and are widely used in modern products such as automobile control motors and cell phones because their powerful magnetic field enables products to be made smaller.
　We are a distributor for a major Chinese magnet manufacturer and can provide neodymium magnets in various shapes to meet the needs of Japanese customers. Chinese magnet manufacturers have low heavy rare earth (HREE) technology and are able to reduce the amount of heavy rare earths (Dy and Tb) and achieve HREE-free products, thereby reducing the burden on customers.

Main applications:
Used in small products such as mobile phone-related products, hard disk drives, compact disc players, and headphones, as well as in various control motors for automobiles, trains, hybrid cars, and elevator drive motors

Aquarium Fish Food

We have started exporting food for ornamental fish in order to support a “symbiotic society” in which people around the world can enjoy “healing and comfort” and “increased color in their lives” with their pets. At present, we are active as an Asian agent for Mishiro Corporation and Dojo Aquaculture Research Institute. Please feel free to contact us if you have any inquiries.
