Septic Sludge Research Paper

Septic sludge are been produced in our daily life. In well developed country such United States, Japan and others countries which are composite of high population will have large amount of septic sludge. According to The Local Authorities, the septic sludge is removed from the residential and commercial once in 4 and 2 years respectively. Then, the septic sludge form government buildings, schools, premises used for religious purposes and hotels, hostels, lodging houses and industrial properties are collected once a year and 6 months respectively as the sludge been produced is higher compare to residential and commercial areas. The septic sludge consists of coarse materials such as clothes, sanitary napkins, grit materials such as stones and

Septic sludge is delivered by the Local Authorities through the garbage truck. Garbage truck will collect all the septic sludge from all the places around the town or residential areas according to the period of time that have been set. The different areas are having different of populations. The different populations will determine the period of septic sludge have to been collected. The garbage trunk will finish the collection and carry the septic waste to the reception station to unload the septic sludge. When the garbage is send to the reception station, he preliminary process is been carried out. Those processes are screening and grit removal. The bar screens or mesh screens of different sizes are used to optimize solids removal. The septic sludge will be send into a machine for screening to remove the bulky solids such as cans, rags, sticks, plastic packets and other (Parr et al., n.d.). The screening is always done with an automated mechanically raked bar screen in modern plants which are dealing with large populations, whereas in smaller or unmodern plants, cleaned screen is conducted manually. The raking action of a mechanical bar screen is depends on the accumulation on the bar screens or flow rate. When the solid wastes are entrained in pipes and moving parts of treatment plants, they will cause the damage to certain parts of the plants and affect the efficiency of the process. Then the grit removal is been carried out to

The landfill must be fully equipped with laminated composite linear system, storm water drainage system, leachate collection system and covering of the landfill. The storm water drainage system is used to collects rain water that falls on the landfill and the leachate collection system is used for collection of water that has percolated through the landfill itself and contains contaminating substance which known as leachate. The all equipment are used to prevent the leakage of the leachate from flowing out to the drains and seeping into the ground. For the wastewater extracted during the dewatering process in the quicklime stations will be treated in SBR. SBR are a treatment for special form of activated sludge. The all process are takes place in the reactor tank and clarifiers are not required. In SBR, the wastewater will be treated in batch mode and each batch is sequenced through a series of treatment stages. Typical SBR process is start from fill stage. The wastewater fills the tank first, mixing with biomass which remained in the tank during the previous cycle. Next, air is added to aid the biological growth and facilitate subsequent waste reduction in react phase. Then, mixing and aeration stop during the settle stage to allow the solids to settle to the bottom of the tank. Finally the clarified effluent discharged in draw or decant phase. If there is any sludge left, it will be removed in
