Xingtai Foam-Sealing Mobile Toilet
The Xingtai foam-sealing mobile toilet is a water-saving toilet system that achieves sealing and cleaning functions through foam. Its core principles, workflow, system composition, and advantages are as follows:

Core Principles
This system uses a foaming device to mix air, water, and specially formulated foam liquid in proportion, generating a large amount of fine foam that covers the inner walls of the toilet bowl and the drainage outlet. The foam layer prevents odors from rising through physical sealing, reduces the adhesion of waste with its lubricating properties, and aids in sliding down. Additionally, the surfactant components in the foam have self-cleaning properties, reducing the risk of waste residue.
Workflow
- Standby Mode: The toilet bowl remains dry or pre-filled with a small amount of foam to maintain basic sealing.
- Sensor Activation: The system is triggered by a foot pedal, manual button, or infrared sensor.
- Foam Generation: The nozzle sprays mixed foam to fully cover the inner walls of the toilet bowl and the drainage outlet.
- Waste Discharge: The foam wraps the waste and slides it into a storage container or treatment unit, with extremely low water consumption (some models require no flushing).
- System Reset: After waste discharge, foaming automatically stops, and the system returns to standby mode.
System Composition
- Toilet Bowl: Made of anti-stick material with a designed slope to facilitate foam coverage and waste sliding.
- Foaming Device: Includes a foam liquid storage tank, micro air pump, water pump, mixing chamber, and control circuit, responsible for foam generation and delivery.
- Control System: Fully intelligent control with a microcomputer PLC, featuring an LCD touch screen to display operating status, with low failure rates and easy maintenance.
- Foam Liquid: A specially formulated surfactant solution that must be easy to foam, moderately stable, biodegradable, and environmentally friendly.
- Drainage Pipeline and Treatment Device: Connects to septic tanks, biogas digesters, or sewage treatment facilities to achieve harmless waste treatment.
Advantages
- Outstanding Water-Saving Performance: Relying on foam for cleaning, the water consumption per use is less than 1/10 of that of traditional toilets.
- Strong Environmental Adaptability: Can operate independently of municipal sewage networks, reducing infrastructure costs, and is suitable for water-scarce or remote areas.
- Intelligent Management: Automated control reduces manual intervention, with real-time display of operating parameters on the LCD screen for easy maintenance.
- Excellent Hygiene Performance: The foam seal effectively blocks odors, reduces bacterial growth, and improves the toilet environment.
