One Tank, Full Biological Treatment: AAO + MBBR

The SB range combines an Anaerobic–Anoxic–Oxic (AAO) biological train with Moving Bed Biofilm Reactor (MBBR) carrier media inside a single factory-integrated tank. The AAO stages strip organic pollutants and nutrients, while the MBBR media grow a dense, stable biofilm that keeps performance consistent through the load swings typical of village, tourist and small-enterprise sewage. The result is an integrated sewage treatment plant that needs no operator attention between scheduled visits and keeps effluent compliant with local discharge standards.

Built for Distributed Sewage Treatment

Rural Communities & Villages

Where municipal sewer networks do not reach, a buried SB unit treats the whole settlement's domestic sewage on site — the ground above can stay in use as parking, landscaping or a road.

Tourist Attractions & Homestays

Scenic areas and village homestays face sharply seasonal visitor loads. The AAO + MBBR train holds performance through weekend peaks, and the optional solar package suits remote mountain or island sites.

Highway Service Areas

Remote service areas have no sewer connection and often an unreliable grid. SB units run automatically with solar support, cutting operating cost and the need for routine attention.

Schools & Enterprises

Boarding schools, factories and business campuses produce steady domestic sewage that is well matched to the 20–100 m³/d SB range, with treated water reusable for irrigation and flushing.

Hotels & Small Resorts

A compact packaged STP for hotels that want to treat on site instead of paying for septic haulage — installed below the car park or service yard, invisible to guests.

Designed for decentralized treatment of industrial or communal wastewater, this horizontal-tank system processes tens of tons of effluent daily through a continuous, enclosed flow. Wastewater first enters a primary zone for sedimentation and anaerobic digestion, then moves through an extended aerobic biological reactor where microorganisms break down organic matter and nutrients. Following secondary clarification within the tank, the treated water undergoes final disinfection, consistently meeting discharge or reuse standards. The fully automated, space-efficient horizontal design ensures reliable, large-capacity operation with minimal footprint and maintenance.

One Supplier for the Whole Sewage Treatment Family

The SB integrated plant sits in the middle of the Mejec range. Below it, the buried Johkasou SA covers 1–5 m³/d for single homes; above it, containerised MBR / MBBR units scale from 50 m³/d to combined plants of 10,000 m³/d, and the MABR containerised system adds an energy-saving option where power is expensive.

FAQS

  • What makes the Mejec-Johkasou-SB suitable for decentralized rural sewage treatment?

    The Mejec-Johkasou-SB is specifically engineered for decentralized sewage treatment in areas like rural communities, tourist attractions, and village homestays. Its high degree of integration combines the AAO + MBBR combined biological treatment process into a single, compact unit. This allows for fast deployment and ground mounted installation without the need for extensive infrastructure, making it perfect for distributed locations where centralized sewage systems are not feasible.

  • Can the Mejec-Johkasou-SB operate with solar energy in remote locations?

    Yes, the Mejec-Johkasou-SB features advanced Solar energy integration technology. This capability allows the plant to operate efficiently in off-grid or remote areas, such as highway service areas or isolated tourist spots, where stable power supply might be a challenge. By utilizing solar power, the system not only ensures automatic operation but also significantly contributes to low cost operation by reducing reliance on grid electricity.

  • What is the daily treatment capacity of the Johkasou-SB unit?
