Tianjin Foam-Sealed Mobile Toilet
The Tianjin foam-sealed mobile toilet is a portable sanitation facility that utilizes foam-sealing technology, offering water-saving and environmentally friendly features. It is suitable for outdoor temporary scenarios and can be rented or purchased for use.

Working Principle and Water-Saving Characteristics
The foaming device mixes a small amount of water with a specialized foaming agent, generating fine and stable foam through compressed air or mechanical agitation. The foam rapidly fills the toilet trap, forming a sealing layer that effectively blocks odors, lubricates the toilet to allow waste to slide into the collection tank, and possesses antibacterial properties. Its water-saving advantage is significant, saving approximately 80% of water compared to traditional flush toilets. Moreover, the foaming agent formula is adjusted for the climate in Tianjin to ensure foam stability in high or low-temperature environments.
Design and Convenience
- Material and Portability: The main body is constructed from lightweight materials (such as steel structures or composite materials), facilitating easy transportation and rapid installation, making it suitable for temporary deployment.
- Internal Structure: It integrates a toilet, foaming device, collection tank, and ventilation system. The cleaning cycle of the collection tank depends on the frequency of use and generally supports extended periods of operation.
- Application Scenarios: Designed for outdoor activities, it does not require connection to complex sewage systems and can be quickly set up in parks, construction sites, temporary event venues, etc. For example, community event organizers in Tianjin often rent these toilets, requiring only regular replenishment of the foaming agent and cleaning of the collection tank.
Environmental and Hygiene Performance
- Environmental Friendliness: It reduces water consumption, with foam coverage minimizing odor emission. The foaming agent is mostly composed of biodegradable ingredients, making disposal simple and minimizing pollution to soil and water bodies.
- Hygiene: The foam layer isolates waste, reducing the risk of cross-contamination, while the ventilation system further optimizes air quality.
Pricing and Customization Services
- Price Range: The cost of renting or purchasing varies significantly depending on specifications and features. Ordinary models start at approximately 2000-7500 yuan, while high-end customized versions can reach tens of thousands of yuan.
- Customization Options: Cangzhou Hengtai Sanitation Equipment Co., Ltd. offers on-demand customization services, with product model ht-055, dimensions 120015003000, suitable for temperatures ranging from -30℃ to 40℃, and material options including color steel plates and metal carved panels.
Rental Service Model (Example: Hexi District, Tianjin)
- Applicable Scenarios: Targeted at projects with construction periods of 1-6 months, the cost includes equipment fees, transportation and installation fees, and regular cleaning and disinfection service fees.
- Environmental Adaptability: The outer shell is made of fiberglass or HDPE, with an internal foamed wall featuring a double-layer structure. It can operate stably in environments ranging from -20℃ to 50℃, with internal temperature fluctuations of less than 5℃. It is equipped with adjustable feet to adapt to uneven ground.
- Service Standards: Regular rental companies develop cleaning plans based on the number of users, with cleaning efficiency higher than that of traditional mobile toilets. They also provide technical parameters such as the daily processing capacity of a single device and the cleaning interval in days.
