Method for treating sewage and other liquids

A method for treatment of wastewater, said wastewater of the type comprising organic matter and associated dissolved gases, said method comprising:

• (a) providing a series of increasingly finer media portions in the direction of wastewater flow, said series of increasingly finer media portions each having a sufficiently coarse size to thereby provide a packed porosity of sufficient volume that substantially precludes clogging of the next finer media portion, said series of increasingly finer media portions comprising two or more preselected media portions, said two or more preselected media portions comprising at least (i) a first media portion and (ii) a final media portion, said final media portion being finer in size than said first media portion, said final media portion having a larger surface layer area than said first media portion, and
• (b) providing a common container for said two or more preselected media portions, said common container having an edge portion;
• (c) providing a downward leg portion adjacent said said edge portion;
• (d) directing said wastewater into said first media portion;
• (e) allowing said wastewater to flow by hydraulic action from said first media portion to said final media portion, without saturating all of said final media portion with said wastewater;
• (f) allowing said wastewater to flow by hydrophilic action from said final media portion to said downward leg portion;
• (g) and wherein the number, porosity, and volume of each of said preselected media portions is selected so as to allow said organic matter and said dissolved gasses to be substantially removed from said wastewater, so as to provide a treated wastewater effluent.

A method for treatment of wastewater, said wastewater of the type comprising organic matter and dissolved gases, said method comprising:

• (a) providing a container, said container having an edge portion;
• (b) providing a downward media leg portion, said downward media leg portion (i) adjacent said edge portion, and (ii) containing therein at least one film forming layer portion;
• (c) directing said wastewater into said container;
• (d) allowing said wastewater to flow by hydrophilic action from said container to said downward media leg without saturating all of said at least one film forming layer portion with said wastewater;
• (e) wherein said wastewater flows in a thin film through said at least one film forming layer portion, whereby said wastewater is effectively treated for removal of organic matter, so as to provide a treated wastewater effluent.
