FRP/GRP septic tank is an ideal tank for toilet drain when there is no sewage system and construction chain. 0.5m3 -5m3 septic tanks are suitable for toilet drain and several houses, more bigger one will be used for residence community, supermarket and hotel etc.
Volume range: 0.5-500m 3, above 100m 3 will be fabricated on site or several septic tanks to work together.

Eco-friendly
Rust proof and leak proof compare with
Durable: over 30-year service life underground
Light weight and easy to install: it's 1/4 of steel weight, 75kg / set, easy for installation.
Excellent performance on reduction of BOD
Easy to transport: as our molded septic tank can be stackable so it can save a lot of space. 144 sets of 1.5M3 septic tanks can be transported via 1x40' container. 

Following specifications available for molded FRP/GRP septic tanks. 

Septic tank is primary treatment structures which remove the suspended matter in domestic sewage by adopting sediment and anaerobic fermentation principle, domestic sewage contain plenty of feces, Paper Scrap, parasite etc impurity, the suspended solid concentration is 100-350mg, organism concentration BOD5 is between 100 to 400mm, the suspended organism BOD is 50 to 200mg among of them. sewage enter into septic tank will remove 50% to 60% suspended matter after 12 to 24h sediment , the sediment sludge will anaerobic digestion above 3 month, which will make the organism decompose stable inorganics, corruptible raw sludge translate to ripe sludge , it changed sludge structure, reduce sludge water ratio, clear it and transport out regular. Landfill or reuse it as fertilizer.

When the toilet sewage water flow into 1st chamber, the sewage water begin to ferment and decompose. The manure, etc can be naturally divided into three layers due to different specific gravity.
The upper layer is paste-like feces, the lower layer is blocky or granular feces, and the middle layer is relatively clear.
In the upper layer of the faeces and the lower layer of faeces, the bacteria and parasite eggs are the most, and the middle layer contains the least eggs. The intermediate fermented septic liquid overflows into the second chamber through the septic tube, and most of the unfertilized faeces and the dung residue is precipitated and retained in the first tank as buttom layer (anaerobic sludge layer) to continue the fermentation in anaerobic evironment. The fecal liquid flowing into the second chamber is further fermented and decomposed, the eggs continue to sink, the pathogens gradually die, the fecal liquid is further detoxified, and the thickness of the feces and feces is significantly reduced compared with the first chamber. The fecal fluid flowing into the third chamber is generally decomposed, and the pathogens and parasite eggs have been basically killed. The third chamber function mainly serves to store the sludge that has been basically harmless.
