Tongren Foam-Sealing Mobile Toilet
Admin October 08, 2026
The Tongren foam-sealing mobile toilet is a temporary sanitation facility that utilizes foam-sealing technology to achieve water conservation and odor control, suitable for various outdoor scenarios, featuring high efficiency, environmental friendliness, and flexibility.

Working Principle
The core technology of the foam-sealing mobile toilet involves generating a large amount of fine foam through a foam generator, replacing the traditional water-flushing method for cleaning and sealing. Its workflow consists of three steps:
- Foam Generation and Injection: Specialized foaming agent is mixed with water and then compressed air is used to form high-density foam, which is injected into the toilet bowl through pipes.
- Foam Sealing and Lubrication: The foam layer covers the surface of the excreta, forming a physical barrier that isolates air and odors while lubricating the inner walls of the toilet bowl to reduce residue.
- Sewage Discharge and Collection: The excreta, mixed with a small amount of foam, is discharged into a sealed fecal storage tank through gravity or a vacuum system and is regularly collected and transported by specialized vehicles for treatment.
Core Advantages
- Outstanding Water Conservation Performance: Only 0.1-0.3 liters of water are required per flush, with a water-saving rate exceeding 90%, making it particularly suitable for water-scarce areas like Tongren or outdoor temporary events.
- Significant Odor Control and Insect Prevention Effects: The foam layer effectively blocks the diffusion of odors and inhibits the breeding of mosquitoes and flies, improving the hygiene of the toilet environment.
- Flexible and Convenient Installation: The modular design supports rapid assembly and disassembly, adapting to the needs of temporary scenarios such as music festivals, sports events, and construction sites.
- Comprehensive Customization Services: Size adjustments, internal layout optimization, and appearance customization services are provided to meet the needs of events of different scales and styles.
Application Scenarios
- Outdoor Temporary Events: Such as music festivals and marathon events, solving short-term high-traffic toilet problems.
- Tourist Attractions: Providing environmentally friendly sanitation facilities in remote mountainous areas or nature reserves lacking sewer networks.
- Construction Sites: Offering workers an odor-free and easy-to-clean toilet environment, improving construction efficiency.
- Vehicle-Mounted Mobile Toilets: Installed on vehicles or trailers for flexible movement, suitable for emergency rescue or巡回 (it seems '巡回' here means 'round-the-clock' or 'itinerant' service, so we can use 'itinerant') itinerant services.
This technology, by replacing water resources with foam, balances functionality and environmental friendliness and has become one of the mainstream choices for temporary sanitation facilities in the Tongren area.
