Zhangye Foam-Sealing Mobile Toilet

Admin October 08, 2026

The Zhangye foam-sealing mobile toilet is a water-saving public sanitation facility suitable for scenarios without water or sewer systems, achieving efficient odor isolation, clog prevention, and pipe-free operation through foam flushing instead of water.

Working Principle and Water-Saving Performance

This toilet generates high-density foam by mixing a foaming agent with water (in a ratio of approximately 1:1000) under microcomputer control. The foam automatically covers the toilet bowl and waste surface, forming a dual odor-blocking layer. The foam layer not only lubricates the pipes to prevent clogging but also seals off unpleasant odors. The drain outlet features a flexible design to reduce fly and mosquito breeding. Its water-saving performance is remarkable, with water consumption per use < 50ml and a water-saving rate of 90%-98%, resulting in almost no sewage discharge, making it particularly suitable for arid regions like Zhangye.

Technical Adaptability and Functional Expansion

  • Low-temperature environment adaptability: Optional low-temperature foaming agents and heating systems ensure normal operation in extreme cold conditions ranging from -20℃ to -30℃.
  • Flexible sewage disposal: Supports direct discharge into fecal collection tanks without a pipe network or connection to municipal sewers. Some models are equipped with biodegradation technology, enabling maintenance-free cleaning.
  • Diverse energy supply options: Optional photovoltaic self-powering systems are available, suitable for scenic spots without electricity or campsites, reducing reliance on traditional power grids.

Structural and Material Design

  • Main frame: Constructed from lightweight alloys or composite panels, featuring rapid assembly and disassembly for easy transportation and deployment.
  • Toilet bowl material: For example, a 304 stainless steel foaming squat toilet equipped with infrared sensors, supporting circumferential flushing, and a 120mm diameter sewage pipe to ensure smooth waste discharge.

Application Scenarios and Maintenance Requirements

  • Tourist attractions: Installed along sightseeing routes to address the lack of water and sewer systems in remote scenic spots.
  • Temporary events: Quickly deployable for high-sanitation-standard scenarios such as music festivals and sports events with large populations.
  • Construction sites: Provides an odor-free restroom environment for workers, enhancing work comfort.
    Maintenance aspects: Requires regular cleaning of fecal collection tanks or replacement of biodegradable materials. Long-term use may lead to material aging, and extreme weather conditions (such as sandstorms) may affect the stability of the sealing structure.

Environmental Adaptability Optimization

To address the characteristics of drought, frequent sandstorms, and large temperature variations between day and night in Zhangye, this toilet extends foam stability through anti-evaporation water storage design and strengthens sealing structures to reduce sand intrusion, ensuring continuous and stable operation in harsh environments.
