Johkasou-Based Packaged Sewage Treatment Plant (HL-STP Series)
Short Description
The Hydronovus Johkasou system is a compact, plug-and-play decentralized sewage treatment solution designed for rapid deployment. Housed within a highly durable, mass-produced SMC (Sheet Molding Compound) or GRP (Glass Reinforced Plastic) shell, this all-in-one unit integrates advanced biological processes (including our high-performance MBBR media) to deliver consistent, compliant effluent. Offering daily treatment capacities from 0.5 to 100 tons per day, it is the ultimate low-footprint solution for rural communities, remote construction sites, and off-grid facilities.
🌟 Key Engineering Advantages
- Ultra-Durable Corrugated Shell: Features a patented corrugated structural design. The standardized SMC/GRP shell offers exceptional high-strength mechanical integrity, ensuring safe underground burial even in freezing soil conditions or areas with heavy surface loads.
- Advanced MBBR Integration: The core biological compartment utilizes our premium MBBR media. This ensures a remarkably high biomass concentration, providing superior pollutant removal (COD, BOD, Ammonia) and excellent resistance to hydraulic shock loads.
- True Plug-and-Play Installation: Drastically reduces civil construction time and costs. The system arrives pre-assembled and ready to drop into the excavation site. Simply connect the inlet, outlet, and power, and the system is ready to operate.
- Low OPEX & Zero Nuisance: Engineered for exceptionally low energy consumption and minimal noise output. The highly efficient biological process also results in significantly reduced sludge generation, lowering your ongoing disposal costs.
- Smart Automation & Remote Control: Equipped with a fully automatic PLC control system. Requires virtually no daily manual intervention and supports optional remote monitoring for off-site management.
🏭 Typical Applications
Ideal for decentralized and point-source wastewater treatment where building a massive concrete WWTP is financially or geographically impossible:
- Remote Infrastructure: Highway service stations, toll booths, and remote mining/construction worker camps.
- Residential & Hospitality: Rural villages, decentralized residential communities, scenic tourist spots, hotels, and resorts.
- Institutional: Off-grid hospitals, schools, and ecological protection zones requiring strict discharge compliance.
