Mejec-SA Small-Scale Johkasou for Decentralized Wastewater Treatment

Wastewater treatment is an important part of infrastructure development, not only in large urban areas but also in rural communities, small residential developments and remote locations. In places where centralized sewer networks are unavailable or impractical, compact decentralized wastewater treatment systems offer a flexible approach to managing domestic wastewater.

To meet these needs, Mejec offers the SA small-scale Johkasou, with a daily treatment capacity of 1–5 m³. Designed for small-scale applications, the system features a compact modular structure that allows flexible installation in different site conditions while minimizing space requirements. It adopts Moving Bed Biofilm Reactor (MBBR) technology, using moving biofilm carriers to support microbial growth and biological pollutant removal, helping maintain stable treatment performance and effluent quality.

Applications Across Different Settings

With its compact design and flexible installation, Mejec-SA is suitable for a variety of decentralized wastewater treatment scenarios, including rural homes, private residences, homestays, small guesthouses, farms and other small-scale accommodation facilities. It can also be considered for remote sites where connecting to centralized wastewater infrastructure is challenging.

Mejec has accumulated project experience in wastewater treatment across different countries and regions, supporting diverse applications and local treatment requirements. Through its range of decentralized wastewater treatment solutions, Mejec continues to provide practical options for projects of different scales.

For small-scale wastewater treatment needs, Mejec-SA combines an appropriate treatment capacity, modular design and MBBR technology in one compact system.
