Introduction to Foam Mobile Toilets
Foam mobile toilets are a new type of environmentally friendly toilet facility that utilizes foam sealing technology to achieve water conservation, odor prevention, and intelligent management, featuring high-efficiency water conservation, multiple odor prevention measures, and strong adaptability.
1. Outstanding Water Conservation and Environmental Protection Performance Foam mobile toilets replace traditional water flushing with foam generated by foaming liquid, requiring only 0.04 liters of water per use, with a water conservation rate exceeding 90%. Its core U-shaped pipe liquid level balancing system stabilizes the amount of foaming liquid, ensuring a continuous foam layer covers the surface of excreta. Measured data from Beijing Olympic venues shows that this technology achieves a water conservation rate as high as 98%, with each toilet stall saving approximately 50 tons of water resources annually. Additionally, the foaming liquid is formed by activating a special formula of foaming agent mixed with water at a ratio of 1:100 using compressed air, further reducing water consumption.
2. Triple Odor Prevention Design The device achieves efficient odor prevention through physical isolation, mechanical sealing, and biological decomposition. Firstly, a foam layer approximately 5 centimeters thick completely covers the excreta, blocking the diffusion of odors; secondly, the sewage outlet employs a specially made heavy hammer baffle for secondary sealing to prevent gas backflow; finally, the addition of microbial flora in the fecal storage tank rapidly decomposes organic matter, reducing odor production at the source. Measurements indicate that the ammonia concentration in the toilet can be reduced to below 0.1ppm, meeting indoor air quality standards.
3. Core Components and Operating Principles The core components of foam mobile toilets include a foaming cylinder, a liquid storage tank, and a liquid level balancing tank. The foaming cylinder utilizes the principle of the U-shaped pipe to stabilize the amount of foaming liquid, generating a long-lasting foam layer in conjunction with compressed air; the liquid storage tank is responsible for storing the foaming liquid, while the liquid level balancing tank maintains a stable liquid level through gravity. During operation, the foaming liquid is activated by compressed air to form fine foam, covering the surface of the excreta to form a sealing layer while reducing flushing water usage.
4. Strong Adaptability and Wide Range of Application Scenarios The device adopts a lightweight modular design, with the toilet fixture body made of stainless steel, requiring only a 220V power supply to operate, with a daily power consumption of less than 0.2 degrees. The built-in electric heater ensures normal foaming in low-temperature environments as cold as -35°C, while the aluminum alloy frame combined with insulated wall panels keeps the indoor temperature comfortable. Its application scenarios cover conventional locations such as city streets, scenic spots, and construction sites, as well as extreme environments like along the Qinghai-Tibet Railway and Antarctic research stations.
5. Intelligent Management and Resource Utilization The microcomputer intelligent control system can automatically monitor foam residue levels, initiate the crushing device on schedule, and control lighting through sound activation, reducing manual maintenance costs. Beijing toilet renovation projects have demonstrated that compared to traditional mobile toilets, the frequency of waste removal is reduced by 80%, and overall operating costs are saved by 60%. The new generation of devices also achieves on-site resource utilization of feces, with the treated sediment liquid infiltrating into the soil through capillary tubes, becoming a natural nutrient for plants and forming an ecological closed loop.
