A vermifilter toilet is a composting toilet with flushing water where earthworms are used to promote decomposition to compost. Composting toilets do not require a connection to septic tanks or sewer systems unlike flush toilets . [ 2 ]
An external fill point for filling the fresh water tank made up of a large diameter hose that runs into the tank and incorporates a hole in the side of the RV which allows water to be fed, via a water hose, into the tank using gravity alone. A smaller diameter 'vent' hose is usually installed alongside to allow air to escape the tank when filling.
A portable toilet is not connected to a hole in the ground (like a pit latrine), nor to a septic tank, nor is it plumbed into a municipal system leading to a sewage treatment plant. The chemical toilet is probably the most well-known type of portable toilet, but other types also exist, such as urine-diversion dehydration toilets, composting ...
The RBC process allows the wastewater to come in contact with a biological film in order to remove pollutants in the wastewater before discharge of the treated wastewater to the environment, usually a body of water (river, lake or ocean). A rotating biological contactor is a type of secondary (biological) treatment process.
A corepressor downregulates (or represses) the expression of genes by binding to and activating a repressor transcription factor. The repressor in turn binds to a gene's operator sequence (segment of DNA to which a transcription factor binds to regulate gene expression), thereby blocking transcription of that gene.
The holding tank can be safely emptied at a dump station. Greywater holding tanks can also be emptied at a dump station. Dump stations are often located at campgrounds , RV parks , truck stops , RV storage facilities, highway rest areas, recreation vehicle dealerships, marinas and other places that are frequented by recreational vehicles and boats.
The aeration stage and the disinfecting stage are the primary differences from a traditional septic system; in fact, an aerobic treatment system can be used as a secondary treatment for septic tank effluent. [1] These stages increase the initial cost of the aerobic system, and also the maintenance requirements over the passive septic system.
Whilst a dry toilet can be with or without urine diversion, a pit latrine is almost always without urine diversion. The key characteristic of a pit latrine is the use of a pit, which infiltrates liquids into the ground and acts as a device for storage and very limited treatment. [7] Pit latrines are sometimes also referred to as "dry toilets ...
