Process for the treatment of waste

A method for continuous processing of organic waste having a liquid component and a solid component, comprising the steps of:

• adding ash to said organic waste, said ash serving to weight said organic waste;
• separating said weighted organic waste to isolate said liquid component from said solid component;
• oxidizing said solid component of said organic waste in an accelerated wet oxidation reaction to lower the oxygen demand of said solid component and to form a liquid effluent and an ash, said ash being used in said ash-adding step;
• de-ammoniating said liquid component to form a de-ammoniated liquid stream;
• adding said liquid effluent to said de-ammoniated liquid stream to form a combined liquid stream;
• and
• contacting said combined liquid stream with biologically active microbes to reduce the oxygen demand of said combined liquid stream and to form a low oxygen demand stream.

A process for treating organic waste having an oxygen demand, comprising the steps of:

• weighting said organic waste with an internally-derived ash, said weighting step including combining said organic waste with said internally-derived ash to form a weighted organic waste and mixing said weighted organic waste to substantially, evenly distribute said internally-derived ash in said organic waste;
• separating said weighted organic waste into a solid component and a liquid component, said liquid component having at least a portion of said oxygen demand of said organic waste;
• oxidizing said solid component in a wet oxidation reaction in a vertical, down-hole wet oxidation reaction apparatus to form said internally-derived ash for use in said weighting step and to form a liquid effluent;
• de-ammoniating said liquid component to form a de-ammoniated liquid stream;
• combining said de-ammoniated liquid stream with said liquid effluent to form a combined stream;
• contacting said combined stream with biologically active microbes to reduce the oxygen demand of said combined stream and to produce a low oxygen demand stream;
• and
• filtering said low oxygen demand stream to form a deionized stream.

A method for processing waste containing organic matter which includes the wet oxidization of said waste to produce an ash having a first COD level, said method comprising the steps of:

• combining said ash with said waste to form an ash-weighted waste;
• separating said ash-weighted waste into a liquid portion and a solid portion;
• and
• oxidizing said solid portion in a wet oxidization reaction such that said first COD level of said ash is reduced to a second COD level.

A method for treating waste containing organic matter comprising the steps of:

• diluting said waste with a substantially de-ammoniated, deionized diluent;
• chemically reacting said diluted waste in a wet oxidization reaction apparatus to substantially lower the oxygen demand of said waste and to produce a liquid effluent, an ash, and a mixture of gases;
• separating said liquid effluent, said ash and said gas mixture;
• de-ammoniating said liquid effluent to form a de-ammoniated liquid stream;
• contacting said de-ammoniated liquid stream with biologically active microbes to lower the oxygen demand of said liquid stream;
• and
• treating said liquid stream after said microbe contacting step by ultrafiltration followed by reverse osmosis to produce said de-ammoniated, deionized diluent.
