Urial Bin receives vast amount of harsh biological wastes such as spectrum,urine,vomiting,and numerous un-imaginable hard objects o cigaretts buds,toothpicks,paper etc...in du times,the biological wasters will turn into biosolids with the help of the bacteria and the hard objects provide carbon source to enrich the bioactivities and ideal nesting place for the biosolids cloggingand constricting the Urinal Bin Siphon "U" tube, the lateral sewer pipe and eventually caused Urinal Bin Flooding. Traditionally,physical excavation is the only way to unclog the Urinal Bin Siphon Tube and its connecting piping.This passive method is not just time consuming,it also unhygienic and very expensive as well. Bio-cleaner of toliet pipe is hybrid form of POA system, preventing the Urinal Bin Siphon tube and its connecting piping constriction, it does this in two ways: 1)it oxidizes microbial slimes that block leach lines; 2)it decomposes once permeated into the Urinal Bin Siphon Tube and its connecting piping, liberating air bubble conversion from a liquid to a gas represents a volume expansion whereby the compacted soil is "lifed" and air space restored to th soil structure.
