Fecal Tank of Mobile Toilet

Admin September 29, 2026

The fecal tank of a mobile toilet is a core component for storing or treating fecal sewage from mobile toilets. It comes in various materials, specifications, and types, suitable for different scenarios.

Composition and Function of the Fecal Tank

The fecal tank of a mobile toilet is mainly composed of a fecal sewage storage tank or a fecal sewage treatment device, responsible for collecting, storing, or initially treating the excreta produced by users. Some high-end models are equipped with packaged squat toilets, enabling water-free and electricity-free operation through a fecal storage tank made entirely of 304 stainless steel. Regular cleaning is sufficient to maintain its use, making it suitable for outdoor environments with water shortages or no power supply.

Common Materials and Characteristics

The material of the fecal tank directly affects its durability, cost, and applicable scenarios:

  • Plastic: Lightweight and low-cost, but with weak corrosion resistance, suitable for short-term or low-frequency use scenarios.
  • Color-coated steel/Steel structure: High strength, but prone to rust, requiring regular maintenance, mostly used in temporary event venues.
  • Fiberglass-reinforced plastic: Corrosion-resistant, lightweight, and with a long lifespan, a common choice for public toilets.
  • Aluminum-plastic panel: Lightweight and moisture-proof, but with average impact resistance, suitable for regions with mild climates.
  • Stainless steel (e.g., 304 material): Corrosion-resistant, easy to clean, with the longest lifespan, but relatively high cost, often used in high-end or long-term fixed mobile toilets.

Specification and Brand Selection

Fecal tanks come in various height specifications, commonly ranging from 2.3m to 2.9m, and need to be selected based on the overall design of the toilet (e.g., floor height, sewage discharge method). In terms of brands, manufacturers such as Jinhong Pipeline, Jiasheng, Huajie Lvyuan, Jingqing, and Yizhou offer a diverse range of products covering different materials and functional requirements. For example, Huajie Lvyuan's fiberglass-reinforced plastic fecal tanks are renowned for their corrosion resistance, while Yizhou's stainless steel models emphasize long-term stability.

Application Scenarios and Maintenance

Fecal tanks have a wide range of applications, covering mobile toilets, outdoor toilets, public toilets, and other scenarios. During maintenance, it is necessary to regularly clean the storage tank to avoid blockage or odor; for fecal tanks with treatment devices, the treatment efficiency needs to be checked to ensure compliance with environmental standards. Water-free packaged fecal tanks need to be cleaned periodically according to their capacity to prevent overflow.

In summary, the design of the fecal tank for mobile toilets should comprehensively consider materials, specifications, and usage scenarios. Reasonable selection can enhance the lifespan of the equipment and user experience.
