About Nippon ALSi

Nippon ALSi (Thailand) Co., Ltd. was established in 2011 as a subsidiary of Japan ALSi Co., Ltd. We opened our factory in the Amata City Chonburi Industrial Estate, where we provide comprehensive wastewater treatment services, primarily serving Japanese companies operating within Thailand.
Our philosophy goes beyond simply purifying water. We are dedicated to water treatment processes that minimize waste (sludge) production and reduce the energy consumption required for operations, thereby contributing to sustainable production activities. Based on this mission, we have developed unique proprietary products and services, such as “BIO ALSi" and the "ALSi Floc N100 Series.”

We provide a fully integrated, in-house service range—from the sale of water treatment chemicals to the design, manufacturing, system construction, and operational management support of treatment facilities.
Whether you are implementing a new system for a factory launch or seeking to improve and reduce costs for an existing wastewater setup, we provide the optimal proposal tailored to your specific needs. With Japanese staff permanently on-site, we ensure smooth communication in Japanese for confirming detailed specifications and addressing technical issues. Please feel free to consult us with any water treatment challenges.

Our Service

: What We Can Do

Up to now, we have achieved waste reduction, cost savings, space optimization, and stable automated operation across a wide range of fields, including water-soluble cutting oils, paint wastewater, and high-oil content food industry wastewater.
Wastewater discharged from factory manufacturing processes contains various pollutants, and the optimal treatment method differs for every case. Furthermore, site conditions—such as available installation space and the presence of operational staff—vary significantly from client to client.
In order to provide the most effective solution, we analyze the condition of your wastewater in our own laboratory and carefully confirm each of your specific needs before proposing the ideal wastewater treatment system.
