Beihai Foam-Sealing Mobile Toilet

The Beihai foam-sealing mobile toilet is an innovative and eco-friendly toilet that utilizes foam-sealing technology, offering advantages such as water conservation, odor prevention, and strong adaptability. Its core principle is based on fluid mechanics and interfacial chemistry. Through a foaming device, liquid and air are mixed in specific proportions to form a stable group of microbubbles, which cover the surface of the excretion channel to create a flexible barrier, achieving multiple functions.

Working Principle and Water-Saving Characteristics
The foam-sealing technology operates efficiently through three stages:

1. Foaming and Barrier Formation: The foaming device mixes liquid and air to generate fine microbubbles, which maintain a stable form under a specific formula and cover the pipe surface to form a physical barrier.
2. Odor Blocking and Water Conservation: The foam layer effectively blocks the reverse diffusion of gases in the pipes, reducing the concentration of odors such as ammonia (the measured ammonia concentration is ≤0.1 ppm). At the same time, it alters the interface conditions between liquid and air, reducing the single-flush water volume from the traditional 6-9 liters to 0.04 liters, achieving a water-saving rate of 98% and saving approximately 50 tons of water per toilet per year.
3. Self-Cleaning Function: When new foam is generated, it pushes the old foam carrying impurities along the pipes, enabling automatic cleaning and reducing the need for manual maintenance.

Core Advantages and Application Scenarios

1. Odor Prevention and Environmental Protection: Through physical isolation by foam, secondary sealing with a heavy hammer baffle at the sewage outlet, and microbial decomposition in the fecal storage tank, triple protection ensures efficient odor prevention. The new generation of equipment incorporates microbial technology to enable on-site resource utilization of feces, with the sediment liquid infiltrating the soil to become plant nutrients.
2. Strong Adaptability: With a lightweight and modular design, it can operate with a 220V power supply (daily power consumption <0.2 degrees). An built-in electric heater ensures normal foaming at temperatures as low as -35°C, while an aluminum alloy frame and insulated wall panels maintain a comfortable indoor temperature. It has been applied in extreme environments such as the Shanghai Bund, the Qinghai-Tibet Railway, and Antarctic research stations.
3. Intelligence and Low Cost: A microcomputer system automatically monitors the foam residue, initiates the crushing device on schedule, and controls sound-activated lighting. Maintenance costs are reduced to 5 yuan worth of foaming agent + 2 degrees of electricity per month. The frequency of waste removal is reduced by 80%, and overall operating costs are saved by 60%.
