The first sewage from the water inlet to the first row in the first case, Gerry a large proportion of the solids and parasite eggs precipitate down, the water in the anaerobic bacteria initial fermentation decomposition, the first case of treated sewage can be divided into three layers: skin, clear paste dung, solid and liquid manure the fecal residue. The process of glass reinforced plastic septic tank
After the initial decomposition of fecal fluid flows into the second grid, and floating on the top of the dung and the sediment deposited in the following residues remain in the first grid to continue fermentation. In the second case, the liquid manure to ferment and decompose eggs continue to sink, pathogens gradually die, fecal fluid further harmless, excrement and feces produced by the skin thickness was significantly less than the first.
Fecal fluid flows into the third lattice in general have maturity, which has been basically killing bacteria and parasite eggs. Third grid function mainly from the temporary storage of sediment has been basically harmless fecal function, and finally, after the precipitation of liquid through the drain into the municipal pipe network.
Four septic tank than three septic tank more than a corruption of the fermentation process, the process is more refined, more clean water. The process of glass reinforced plastic septic tank
