Zhoushan Foam-Sealing Mobile Toilet

The Zhoushan foam-sealing mobile toilet is an environmentally friendly mobile toilet that uses foam instead of water flushing to achieve waste sealing, lubrication, and odor control. Its working principle and features are as follows:

Working Principle

1. Foam Generation and Injection
   The device is equipped with a built-in foaming unit. Triggered by sensors, it mixes specialized foaming liquid, a small amount of water, and air to generate a large quantity of fine, dense foam in the foaming chamber. This foam is precisely injected into the toilet bowl, covering the surface of the waste.
2. Foam Sealing and Lubrication
   The foam layer forms a physical barrier that blocks odor from escaping and inhibits mosquito breeding. At the same time, it reduces friction between the waste and the toilet bowl walls through lubrication, allowing the waste to slide smoothly into the collection tank or septic tank below under gravity, preventing blockages.
3. Waste Disposal and Collection
   It adopts either a direct-discharge or fecal tank collection method. The foam mixes with the waste and enters the collection device. Some designs are equipped with removable fecal tanks for easy regular removal and transportation; if connected to a septic tank, centralized treatment is achieved through pipelines.

Core Advantages

• Significant Water Conservation: Each flush requires only 0.1-0.3 liters of water, achieving a water-saving rate of over 90%. It is particularly suitable for water-scarce areas or outdoor temporary events.
• Excellent Odor Control: The foam layer blocks contact between waste and air, inhibiting odor diffusion at the source. Some products are infused with fragrances, emitting a pleasant scent from the foam to enhance the user experience.
• High Adaptability: It is highly compatible with different states of waste (solid/liquid) and is less prone to blockages. It operates within a temperature range of -30°C to 60°C, covering most climatic regions in China.

Application Scenarios

• Outdoor Temporary Events: Such as music festivals, sports events, etc., where rapid deployment and high sanitary standards are required.
• Tourist Attractions: Remote scenic spots or nature reserves lacking water and sewage pipelines.
• Construction Sites: Providing odor-free and sanitary toilet facilities for workers.
• Vehicle-Mounted Mobile Toilets: Installed on vehicles or trailers for flexible movement and use.

Supporting Equipment

It is usually equipped with an exhaust fan (for ventilation and odor control), a lighting system (for nighttime use), coat hooks, a paper towel holder, and a sink. Some high-end models also integrate intelligent sensor flushing, temperature regulation, and other functions to enhance the user experience.
