Mobile Toilet with Foam

Mobile toilets with foam generally refer to foam-sealed toilets or foam-type toilets, which are a new type of energy-saving and environmentally friendly toilets that use low-water-content foam to achieve fecal flushing and odor blocking.

Core Principles and Devices

The core devices of foam-sealed toilets include foam generators, liquid storage tanks, and liquid level balancing tanks. They use the U-shaped tube principle to stabilize the amount of foaming liquid, mixing the foaming agent with water through compressed air to generate a long-lasting foam layer. The high lubricity and sealing properties of the foam can replace traditional water flushing, lubricating feces for easy discharge and blocking the sewage outlet to prevent odors. In 2024, a utility model patent proposed a water-free foaming technology that, when integrated with a fecal biochemical processor, decomposes feces through microbial bacteria and constructs a circulating water system, achieving a water-saving rate of over 99%.

Performance Characteristics

1. Water and electricity saving: The water consumption per person is only about 0.04 liters, and the daily electricity consumption does not exceed 0.2 degrees, which is much lower than that of traditional water-flush toilets.
2. Low maintenance cost: Foam sealing reduces the risk of pipe blockage, and the amount of foaming agent used is small, resulting in lower long-term operating costs.
3. Significant odor control effect: The foam layer effectively isolates odors, and when combined with microbial decomposition technology, it can further purify the air.
4. Strong environmental adaptability: The equipment uses lightweight building materials, making it easy to move and install; it has a wide operating temperature range and can work stably in environments from -40℃ to 50℃.

Structure and Materials

Some products feature an exterior wall with a wood-grain design, equipped with stainless steel toilet door locks and steel structure doors, and internally configured with foam-sealed squat toilets. For example, the 304 stainless steel foam squat toilet is specially designed for harsh environments, with thickened plates that are sturdy and durable, rust-resistant and corrosion-resistant, offering a longer service life. The foam sealing technology effectively prevents odors.

Application Scenarios and Prices

Suitable for scenic spots, construction sites, and other places without drainage facilities. Prices vary depending on the configuration and manufacturer: Products from Beijing Jindongfang Environmental Landscape Engineering Co., Ltd. range from 5605.0 yuan to 12000.0 yuan; products from Lanzhou Jintongchuang Environmental Protection Technology Co., Ltd. range from 1199.0 yuan to 4800.0 yuan; and the outdoor foam-sealed mobile toilet for construction sites from Changzhou Zisheng Environmental Protection Technology Co., Ltd. is priced at 1400.0 yuan.
