Water for Installing Mobile Toilets

When installing mobile toilets, the methods for water treatment and supply mainly include water recycling, hand-washing water supply, and control of flushing water usage, as detailed below:

Water Treatment in Recirculating Mobile Toilets

Recirculating mobile toilets utilize water recycling technology to reuse flushing water. The core principle involves using physical and biochemical methods to purify used flushing water, removing impurities, odors, and harmful substances to meet the standards for reuse in flushing. This technology significantly reduces water consumption, making it particularly suitable for scenarios with limited water resources or long-term use, such as large events and construction sites.

Hand-Washing Water Supply Methods

1. Mobile Toilets Connected to Fixed Water Sources
   In these toilets, hand-washing water shares the same source as flushing water. Fixed water sources, such as municipal water supplies, are connected to the hand-washing sink faucets via pipes. The water pressure is stable, and the supply is sufficient. After use, the hand-washing water is discharged through sewer pipes into a sewage collection tank or directly into the drainage network, ensuring proper sewage treatment.

2. Mobile Toilets Without Fixed Water Sources
   Hand-washing water supply relies on portable water tanks. Typically, a small water tank (with a capacity of approximately 20-50 liters) is installed beneath the hand-washing sink. Before use, clean water must be filled in advance, and the tank needs regular replenishment once the water is depleted. This design is suitable for temporary events or areas without municipal water supply, but attention should be paid to the tank's capacity limitations to avoid frequent refilling that may affect the user experience.

Control of Flushing Water Usage

1. Traditional Water-Flush Mobile Toilets
   These toilets typically use 3-6 liters of water per flush, suitable for scenarios with low water-saving requirements but with relatively high water consumption.

2. Mobile Toilets Using Water-Saving Technologies

   • High-Pressure Air-Water Flush: This method combines high-pressure air with a small amount of water for flushing, using approximately 0.5-0.65 liters of water per flush, achieving significant water-saving effects.
   • Vacuum Negative Pressure Flush: Utilizing the principle of vacuum negative pressure to quickly suction sewage, this method typically uses 0.5-1 liter of water per flush, suitable for scenarios with high hygiene requirements.
   • Air-Water Flush Toilets: For urination, one flush uses 200 ml of water; for defecation, two flushes use 400 ml of water (i.e., 200 ml per defecation flush), achieving efficient water-saving through precise water volume control.

Summary: The water treatment and supply for mobile toilets should be selected based on the usage scenario. Water recycling technology reduces water waste, fixed or portable water tanks meet hand-washing water needs, and water-saving flushing technologies reduce water usage per flush through optimized design. Properly configuring these systems ensures both hygiene needs and efficient resource utilization.
