Improving Wastewater Effluent of Septic Tank Using Filtration Membranes

Journal Name:

Publication Year:

Abstract (2. Language): 
Septic tank one of the on-site systems are commonly used in rural areas, which has a suitable efficiency in sewage treatment. The simplicity of its operation and the low cost of construction and the ease of maintenance rise the depending on the septic tanks in rural areas. One of septic tank disadvantages is low removal efficiency. This study used simple modification of septic tank using filtration membranes of different fabrics such as (cotton, nonwoven polyester, non-woven polypropylene geo-textile 300gm, non- woven polypropylene geo-textile 800 gm. and filter labbad). Study results show that using cotton and non-woven polypropylene geo-textile 800gm improve the removal efficiency of septic tank to (96 % - 97 %) for TSS & 87 % for BOD & (72% - & 75%) for COD.
