How Temporary Mobile Toilets Flush

There are various flushing methods for temporary mobile toilets, including high-pressure air-water flushing, foam flushing, manual flushing, automatic sensor flushing, waterless or water-saving flushing, water-flushing and waterless-flushing suction types, recirculating water flushing, and dry-packing types. Here is a detailed introduction:

High-pressure air-water flushing: This method utilizes the combined action of high-pressure water flow and gas. By mixing water and gas under high pressure and spraying them onto the inner walls of the toilet bowl, it achieves a strong and wide-ranging flush with only one-fifth of the normal water volume. The flushing control is coordinated by an infrared sensor and a computerized intelligent system. When the user leaves, the system automatically triggers the flushing process, enabling efficient water conservation and intelligent management.

Foam flushing: The equipment room is equipped with an automatic foam generator that produces snow-white foam from a mixture to cover the surface of the toilet bowl. The foam layer not only replaces conventional flushing for cleaning excreta but also effectively blocks the emission of odors while significantly reducing water consumption. This technology achieves a balance between environmental protection and hygiene through the dual effects of physical isolation and chemical cleaning.

Manual flushing: There are two types: foot-pedal and button. The foot-pedal type triggers mechanical lever drainage by stepping on the pedal, avoiding hand contact, with a single flush volume of approximately 3-6 liters. The button type controls water release from the tank by pressing a button, with an adjustable flush volume ranging from 4-8 liters per flush. Both rely on the user's active operation and are suitable for scenarios with high cost-control requirements.

Automatic sensor flushing: This method uses an infrared sensor to detect the user's departure signal and automatically triggers the flushing device, commonly found in high-end mobile public toilets. This technology reduces the risk of cross-infection through non-contact control, with a single water consumption of about 2-5 liters, combining hygiene with water conservation.

Waterless or water-saving flushing: This includes foam-sealing and vacuum suction types. The foam-sealing type covers excreta with foam, consuming only 0.1 liters of water and foaming agent per flush. The vacuum suction type uses negative pressure to remove waste, with a water consumption of only 0.5-1 liters per flush. Both break through traditional flushing modes to achieve extreme water conservation.

Water-flushing and waterless-flushing suction types: The water-flushing type is equipped with a water tank and a bottom sewage tank, using a water-flushing device for cleaning. The waterless-flushing type directly collects excreta into the sewage tank, requiring regular suction for disposal. The former relies on a water source, while the latter is suitable for water-scarce environments. Both require a配套 (matching) sewage disposal system.

Recirculating water flushing: This method employs intermittent aerobic and anaerobic treatment technologies, combined with biofilms to accelerate the fermentation and decomposition of fecal sewage. The treated sewage is recirculated for flushing, significantly reducing the frequency of suction and water consumption, suitable for long-term use in mobile toilets.

Dry-packing type: This type has no water-flushing device. Excreta are collected in biodegradable plastic bags, which are automatically replaced with new ones after use and disposed of collectively. This technology completely avoids water usage but requires regular replacement of packing bags, suitable for extremely water-scarce or strictly environmentally regulated scenarios.
