Sewage treatment and recycling system

DETAILED DESCRIPTION It is therefore a primary object of the invention to provide a sewage treatment system for residential or commercial application wherein the treated effluent can safely be used for a variety of purposes, such as irrigation.
It is a further object of the invention to provide a system wherein the treated effluent is potable and is not a source of pollution.
It is another object of the invention to provide an economical, self contained sewage treatment system wherein the sewage is treated in successive steps and the remaining effluent is low in biological oxygen demand and coliform.
Also, a purpose of the invention is to provide a system wherein sewage is treated by aerobic bacterial action resulting in a breakdown of anaerobic bacteria and is subsequently filtered to become a useful effluent.
It is a further object of the invention to provide a sewage treatment system which has a unique filter for cleaning the effluent and rendering it safe for use in irrigation or plumbing systems or other suitable applications.
It is another object of the invention to provide a sewage treatment system in which the effluent is chlorinated prior to being discharged into the surrounding environment or used for other purposes.
Another object of the invention is to provide a sewage treatment system in which a novel means is provided for evenly distributing the effluent over a filter after passing through a septic tank, thereby permitting uniform and complete filtering of the effluent.
There and other objects of the invention will be apparent from the following description of the invention which basically comprises a septic tank having suitable compartments for initially treating the sewage by aerobic bacterial action.
The effluent then flows from the septic tank onto a perforated splash pan which is designed to distribute the effluent evenly over the surface of a first filter which preferably is removable.
The effluent flows through this first filter and then flows through a second filter in which the coliform and biological oxygen demand are reduced to acceptable levels
