Chengde Foam-Sealing Mobile Toilet
The Chengde foam-sealing mobile toilet is an environmentally friendly mobile toilet that uses foam-sealing technology, replacing 'water' with 'foam' as the sealing and cleaning medium.

Working Process
The working process of the foam-sealing mobile toilet covers multiple steps. First is foam generation and coverage. Specialized equipment generates rich and fine foam, which is evenly spread over the inner surface of the toilet fixtures, forming a sealing layer. Next is toilet fixture sealing. The foam effectively prevents odor from escaping, keeping the air inside the toilet fresh. During use, the lubricating effect of the foam allows waste to slide down smoothly, reducing residue. After use, the system flushes and replenishes with new foam to ensure continuous and effective sealing and cleaning. Finally, waste treatment involves waste entering a dedicated collection container, which can then be disposed of in an environmentally friendly manner, avoiding environmental pollution.
Advantages and Features
Compared to traditional mobile toilets, foam-sealing mobile toilets offer significant advantages. In terms of odor control, the sealing effect of the foam effectively isolates odors, providing a more comfortable user environment. Regarding resource consumption, they greatly reduce water usage, addressing the issue of high water consumption in traditional flush toilets. Hygiene is also superior, as the cleaning effect of the foam reduces waste residue and lowers the risk of bacterial growth. In terms of subsequent waste treatment, they avoid the problems of high plastic film consumption in traditional packaged toilets and the potential secondary pollution caused by agents in dry powder/agent degradation toilets.
