There is an apparent curiosity that is growing within Marion County in the subject of septic tanks. The basics on septic tanks were shared by the county Chief Sanitarian through an article who wrote which he distributed to the residents of Marion County. The piece aimed to promote better understanding of the systematic of a septic tank. A septic tank is the best choice for a proper sewerage system in areas where the drainage system has not been fully developed. In order to dispose of waste matter effectively, a filter bed or a tile disposal field must be put into place alongside a septic tank.
The presence of bubbles on fresh sewage makes it appear like soapy water except that it is dark grey in color. There is approximately one pound of solids present in 150 gallons worth of sewage. Of these solids, about one half is mineral and the other half vegetable and animal matter. The vegetable and animal matter composition disintegrates into a forty percent suspension which clears up in time and the other 60 percent in solution that remains unchanged.
Disposal of the settle able and the non settle able portions, and disposal of the effluent water constitute the major problems of sewage treatment. A faster process of putrefaction takes place in a septic tank. Grease and some of the lighter portions of waste matter create scum at the top of the tank while at the bottom, solid portions can be found decomposing.
Credits for the disintegration and decomposition that occur in septic tanks go to the aerobic and anaerobic bacteria. They attack the organic solids and break them up into liquids and gases. The digestion is almost complete with the exception of a small quantity of material which does not decompose and remains in the bottom of the tank as sludge. The bacteria are of utmost importance in the processes of a septic tank. When chemicals are emptied into the tank, or discharged down the drain and reach the tank, the bacteria action is retarded or stopped. Solutions with harmful chemicals and lye are not recommended in unclogging drains.
The amount of liquid that goes into the tank is equal to the amount that is forcefully expelled from the tank and the balance of liquid levels is maintained this way. A septic tank inlet is installed with a baffle so that it may direct incoming sewage towards the base of the tank. This allows fresh sewage to decompose in time and not be discharged immediately and also to keep the scum settled. This aim is completed through the help of the baffle at the outlet of the tank.
While the released waste matter is almost completely rid of solid matter, it is still not pure and it is foul smelling. Rain pipes should never be connected to septic tanks. A common two bedroom home can benefit sufficiently from a 500 gallon septic tank. Larger houses need tanks with a bigger capacity, that is why 1000 gallon septic tanks are suggested. Satisfactory outcomes may be achieved from a septic tank if it is cleaned at least once every three years.
