One Platform, Endless Applications — The LD-SB Johkasou

A closer look at the LD-SB Johkasou wastewater treatment system — a flexible, decentralized solution with projects across different countries.

Flexible Capacity

With a capacity range of 5–100 m³/day, the LD-SB covers everything from small communities to larger decentralized projects on a single equipment platform — simplifying project planning and parts management.

Proven Treatment Process

Its AAO + MBBR process combines Anaerobic-Anoxic-Oxic and Moving Bed Biofilm Reactor technologies in one integrated unit, enhancing nitrogen and phosphorus removal while maintaining stable performance under variable flow and load conditions.

Durable FRP Construction

The FRP material delivers corrosion resistance, lightweight strength, and long service life with minimal maintenance. The same equipment can be installed above-ground for easy access or underground to save surface space.

Intelligent Control

The integrated control system supports automated operation and remote monitoring, reducing the need for frequent on-site attention.

Deployed in projects across different countries and climates, the LD-SB Johkasou delivers consistent treatment performance wherever decentralized wastewater treatment is required.
