THE TREATMENT COMPLETED IN THREE SEQUENCLY STAGES FIRST STAGE – CHEMICAL TREATMENT:- TWO TANKS METAL ARE NEEDED, DIMENSIONAL, TWO METER (LONGS) X ONE METER (WIDENS) X ONE METER (HIGH). FIRST TANK ATTACHED WITH DRAIN BOARD TO SEPARATED THE ACID SOLUTION FROM RICE STRAW (AFTER TREATED); THE WALL OF SECOND TANK IS DOUBLE JACKED. FIRST TANK CONTAINS 100 KG OF RICE STRAW FOR SOAKING IN ACID SOLUTION FOR ONE HOUR FROM 300 LITERS OF WATER, AND 60 LITER OF PHOSPHORIC ACID (97%) MEAN THAT 20% CONCENTRATE, THEN RISE THE TEMPERATURE TO BOILING FOR THREE HOURS. THE EVAPORATE WHICH ISSUE WITH BOILING COLLECTING BY TUBE DIRECTLY TO SECOND TANK WHICH CONTAIN 100 KG RICE STRAW CONDENSING THE EVAPORATE BY WATER RUN IN DOUBLE JACKED. AFTER 3 HOURS OF BOILING, PUT THE TREATED RICE STRAW IN THE DRAIN BOARD WHICH ATTACHED WITH THE FIRST TANK TO SEPARATE THE ACID SOLUTION, THE DRAIN BOARD SUPPORTED BY FILTER TO SEPARATE
TURBIDITY AND SILICA; FOR RE-USING AFTER READJUSTED PH. WHEREAS, ADD 10% FROM CONCENTRATE THE ORGANIC ACID IN THE SECOND TIME; AND 20% IN THE THIRD TIME; OR 40% IN THE FOURTH TIME AS PERCENTAGE FROM RICE STRAW WEIGHT. THE THIRD TANK IS PLASTIC CONTAINING WATER USING IN (1) WASHING THE TREATED RICE STRAW, (2) CONDENSE THE EVAPORATE WHICH COMING FROM FIRST TO SECOND TANK AND (3) JUSTIF- THE ACID SOLUTION WHICH LOST DURING FIRST TREATED FOR RE-USE, NOTED THAT THE WASHING WATER AFTER WASHING THE TREATED RICE STRAW TENDED TO ACIDIC, SO, JUSTIF? BY ADDED 0.5 TO 1% CALCIUM CARBONATE, SECOND STAGE ? GRINDING:- THE TREATED RICE STRAW GRINDING WITH 3% FAT (TO FACILITATE THE GRINDING), AND 4.5% YEASTS. THIRD STAGE – BIOLOGICALLY TREATMENT:- SOAK TREATED RICE STRAW INTO SOLUTION CONTENTS OF 1.5 LITER EM1 AND 1.5 LITER OF MOLASSES AND 7.5 LITER OF WATER WITHOUT CHLORIDE FOR 100 KG TREATED RICE STRAW. TREAD THEM WELL TO REMOVE AIR AND WATER TO OBTAIN THE MOISTURE PERCENTAGE AROUND 30-40%. COVER IT BY VINYL SHEET AND TIED TO OBTAIN ANAEROBIC CONDITIONS AND LEAVE IT FOR 7 DAYS. THE T
