Simple mobile restrooms typically dispose of feces in the following ways:
Chemical treatment: The use of chemical agents to break down and eliminate excreta. This involves the addition of chemicals to control odours and promote the decomposition of the waste, which is then further treated through specialized treatment equipment or into the sewage system.
Anaerobic digestion: Mobile restrooms can utilize anaerobic digestion systems to dispose of excreta. Microorganisms play a role in the system, breaking down and digesting excrement, producing biogas (which can be used for energy) and fertilizer (which can be used in agriculture or horticulture). This method reduces volume, delays processing needs, and is suitable for situations where long periods of time away from the treatment facility are required.
Compression and storage: Waste in a mobile restroom can be compressed and stored to reduce volume and delay the need for disposal. This is often used in situations where you need to be away from the treatment facility for long periods of time, such as camping or off-site construction sites.
Multi-purpose sewage outlets: Mobile toilets may be equipped with manual cleaning functions, such as septic storage tanks or embedded septic tanks, which need to be manually cleaned to store feces and dispose of them centrally. This method requires regular cleaning to keep the mobile toilet clean and hygienic.
Mechanical treatment: Through the use of specialized equipment, the feces from mobile toilets can be treated with solid-liquid separation, decomposition and disinfection. This treatment reduces the environmental impact while maintaining hygiene and safety.
Flushing and non-flushing suction portable toilets: These types of portable toilets may have a water flushing device, while another type of mobile toilet may not have a flushing device and the waste water tank located at the bottom of the toilet will directly receive the excreta of the users. Water-flushing mobile toilets may require a higher suction frequency, while recirculating water-flushing mobile toilets accelerate the fermentation and decomposition of fecal sewage and reduce the number of fecal sewage suctions through the use of anaerobic fecal sewage treatment devices and biological strains.
