Foam-Flush Portable Toilet Tank

Admin October 17, 2026

The foam-flush portable toilet tank is a core device that utilizes low-moisture foam to achieve fecal flushing and odor blocking. Its design integrates multiple features, including foam generation technology, climate adaptability, and material optimization.

Foam Generation Principle and Core Components

The core components of the foam-flush portable toilet tank include a foam generator, liquid storage tank, and liquid level balancing tank, which stabilize the foam liquid volume through the U-tube principle. The foam liquid, formulated by mixing surfactants, stabilizers, and water in specific proportions, generates dense foam in a gas-liquid mixing chamber driven by compressed air. The foam layer covers the waste surface, inhibiting odor diffusion by blocking air contact, while forming a lubricating film on the inner walls of the pipes to reduce solid adhesion and minimize clogging risks.

Climate Adaptability Design

The toilet tank design has been optimized for the climatic characteristics of Hubei Province:

  • Rainy Season: When humidity remains above 80% for extended periods, foam dissipates faster in humid environments. To extend foam retention time to over 8 hours, the stabilizer ratio must be adjusted to enhance foam stability.
  • Winter Cold: When temperatures may drop below freezing, antifreeze components (such as ethylene glycol) must be added to the foam liquid. Additionally, pipes and storage tanks should incorporate electric tracing or insulation layer design to prevent liquid freezing and system failure.

Material and Structural Optimization

Some toilet tanks use 304 stainless steel foam-flush squat toilets, which include the following structural features:

  • Thickened Stainless Steel Body: Corrosion-resistant and easy to clean, suitable for outdoor environments.
  • Foam Generation Device: Integrated within the toilet to generate foam by mixing compressed air with foam liquid.
  • Liquid Storage Tank: Stores the prepared foam liquid, with capacity designed according to usage frequency.
  • Inductive Switch: Automatically controls foam generation and flushing, reducing manual operation and improving hygiene levels.

Application Advantages

The foam-flush portable toilet tank significantly reduces water consumption (saving over 80% compared to traditional water-flush toilets) and minimizes sewage discharge through its foam lubrication and sealing properties. It is ideal for water-scarce regions or temporary event scenarios. Its modular design facilitates quick installation and maintenance, while climate adaptability optimizations ensure stable operation in diverse environments.
