Foam-Flush Mobile Environmental Toilet

The foam-flush mobile environmental toilet is a new type of energy-saving and environmentally friendly toilet that utilizes low-moisture foam for fecal flushing and odor blocking.

Core Principles and Devices

The core principle of the foam-flush mobile environmental toilet is to leverage the high lubricity and sealing properties of low-moisture foam. By mixing a foaming agent with water, foam is generated to replace traditional water flushing methods. Its core devices include a foaming cylinder, a liquid storage tank, a liquid level balancing tank, etc. The U-shaped tube principle is employed to stabilize the amount of foaming liquid, and compressed air is used to generate a long-lasting foam layer. The foam layer not only seals the sewage outlet to prevent odor from escaping but also lubricates feces for easy discharge. In 2024, a utility model patent further optimized the technology, introducing a water-free foaming technique and integrating a fecal biochemical processor. This processor decomposes feces using microbial bacteria and constructs a circulating water system, achieving a water-saving rate of over 99%.

Performance Characteristics

1. Water and electricity conservation: The water consumption per person is only about 0.04 liters, and the daily electricity consumption does not exceed 0.2 kilowatt-hours, significantly lower than that of traditional toilets.
2. Remarkable odor control: The foam layer effectively blocks odors, improving the usage environment.
3. Low maintenance costs: The structure is simple, with a low failure rate, and the water-free foaming technique reduces dependence on water resources.
4. Strong adaptability: The equipment is made of lightweight building materials, facilitating easy movement and installation. It is suitable for places without drainage facilities, such as scenic spots and construction sites. It can operate within a wide temperature range, from -40℃ to 50℃.

Types and Prices

There are various types of foam-flush mobile environmental toilets on the market, such as foam-sealing mobile toilets and single-unit water-free intelligent foam-sealing mobile environmental toilets. Prices vary depending on the model and configuration. For example, the foam-sealing environmental mobile public toilet (including a septic tank) provided by Beijing Jindongfang Environmental Landscape Engineering Co., Ltd. is priced at 5,900 yuan, while the intelligent foam-blocking mobile toilet provided by Lanzhou Jintongchuang Environmental Protection Technology Co., Ltd. is priced at 3,800 yuan.

Application Scenarios

With its water-saving, environmentally friendly, and easily movable features, the foam-flush mobile environmental toilet is widely used in areas lacking fixed drainage facilities, such as temporary event venues, tourist attractions, and construction sites. It effectively addresses the issues of high water consumption and environmental pollution associated with traditional toilets.
