3 ENZYMES ARE NATURAL OCCURING PROTEINS THEY ARE CATALYSTS – THEY INCREASE THE RATE OF CHEMICAL REACTION * * * * ENZYMES CAN DICTATE A REACTION IN SUCH A WAY AS TO ALLOW ONLY CERTAIN BACTERIA TO GROW WHILE OTHER BACTERIA ARE KILLED AND DIGESTED THEY ARE SELECTIVE – THEY CAN BE ‘DESIGNED’ TO CONVERT A CERTAIN TYPE OF NUTRIENTS OR MATERIAL INTO MORE BENEFICIAL MATERIAL

4 ALL PROTIEN GRADUALLY DECOMPOSES THROUGH CHEMICAL REACTION * * OUR ENZYME TECHNOLOGY REDUCES SPECIFIC UNDESIRABLE PROTEINS, FATS, OILS AND GREASES TO ACCEPTABLE LEVELS FOR INTRODUCTION TO WETLAND FILTRATION AREAS WITHOUT COSTLY AERATION OR FURTHER PROCESSING. * THE INTRODUCTION OF ‘DESIGNER’ ENZYMES CAN INCREASE THIS REACTION SPEED MILLIONS OF TIMES AND PRODUCE SPECIFICIED END PRODUCTS.

5 THE DHARA BIOTECH PROCESS PROPOGATES SPECIFIC ACTIVE ENZYMES TO OVERRIDE THE FORMATION OF UNDESIRABLE BACTERIA THAT CONTRIBUTE TO SLUDGE BUILD UP AND FOUL ODORS IN SEPTIC TANKS AND PIPES. INLINE DIGESTION (ILD) * CORROSION IN PIPEWORK IS REDUCED AND FOUL ODORS IN THE SYSTEM ARE ELIMINATED. * ENZYME SUSTAINED RELEASE PACKS ARE PLACE IN THE SYSTEM AND BACTERIA CONVERSION STARTS TO TAKE PLACE IMMEDIATELY. *

7 * * * DHARA BIOTECH SUPPLY SPECIFIC EASY TO USE TREATMENT PACKS FOR INDIVIDUAL SEPTIC TANK TREATMENT. THEY ARE SUPPLIED IN A BIO DEGRADABLE JUTE BAG FOR DIRECT INSERTION INTO THE SEPTIC TANK SYSTEM. THERE ARE 2 STANDARD SIZES AVAILABLE– SMALL - TO TREAT UP TO 2000 LITRES/DAY LARGE - TO TREAT UP TO 5000 LITRES/DAY EACH BAG LASTS 6 MONTHS IF INSERTED DIRECTLY INTO THE EFFLUENT TANK. *

8 * * * FOR INITIAL TREATMENT HANG 1 BAG DIRECTLY INTO THE CENTRE OF THE TANK FULLY SUBMURSED IN THE LIQUID EFFLUENT. SUSPEND ANOTHER BAG IN THE INTAKE FLOW LINE SO INCOMMING EFFLUENT WASHES OVER THE BAG EACH TIME IT ENTERS THE SEPTIC TANK. FOR ONGOING TREATMENT SIMPLY REPLACE THE BAG IN THE MAIN CHAMBER OR EFFLUENT LINE EVERY 6 MONTHS.

9 * * * WORKS PERFECTLY FOR INTERMITTANT USE. MARAI, FORESTRY CAMPS, D.O.C. HUTS, SCHOOL CAMPS, ‘LONG DROPS’, HOLIDAY BATCHES. BY PLACING THE TREATMENT BAG DIRECTLY INTO THE INFLOW LINE, THE SEWAGE IS BEING TREATED AS IT ENTERS THE TANK. WHEN THERE IS NO FLOW INTO THE TANK, THE ENZYME REMAINS DORMENT WHILE THE ENZYME PREVIOUSLY INTRODUCED TO THE TANK WILL CONTINUE TO STIMULATE REACTION. *

10 * * * THE EFFECT OF THIS TREATMENT WILL BE - MOST ‘SESSILE’ – SLUDGE FORMING BACTERIA – WILL BE OVERTAKEN BY ‘PLANKTONIC’ – FREE FLOWING BACTERIA. SLUDGE IN THE SYSTEM WILL BE DRAMATICALLY REDUCED. FOUL ODORS WILL BE ELIMINATED.

11 * PUMP OUTS WILL BE REDUCED CONSIDERABLY THE FULLY TREATED WASTE CAN BE PUMPED DIRECTLY ONTO THE LAND FOR IRRIGATION. * THE ENZYMES ARE CAPABLE OF WITHSTANDING EXPOSURE TO MANY HARSH CHEMICALS USED IN BATHROOMS AND TOILET CLEANING. *

14 THE DHARA BIOTECH PROCESS PROPAGATES SPECIFIC ACTIVE ENZYMES TO OVERRIDE THE FORMATION OF UNDESIRABLE BACTERIA THAT CONTRIBUTE TO SLUDGE BUILD UP IN PIPES AND AERATION PONDS AND REDUCE CORROSION AND FOUL ODORS. INLINE DIGESTION (ILD) * TREATMENT UTILIZES THE EXISTING SEWAGE PIPEWORK SYSTEM AND BEGINS UPSTREAM AT SOURCE. * ENZYME SUSTAINED RELEASE PACKS ARE PLACE IN THE SYSTEM AT COLLECTION POINTS CLOSE TO THE SOURCE. *

15 INLINE DIGESTION (ILD) RAW SEWAGE CONTAINS MOSTLY ‘SESSILE’ BACTERIA – THEY ARE NOT FREE SWIMMING - THEY PREFER TO GROW IN FIXED COLONIES IN PIPES. * * THIS BACTERIA IS THE SOURCE OF FAT AND SLUDGE BUILD UP IN THE PIPEWORK AND PONDS CAUSING FOUL ODORS AND CORROSION. * ‘PLANKTONIC’ BACTERIA ARE ALSO PRESENT IN LESSER NUMBERS. THEY ARE FREE SWIMMERS AND MULTIPLY QUICKLY.

16 INLINE DIGESTION (ILD) DHARA BIOTECH ENZYME PACKS PROMOTE THE GROWTH OF A NUMBER OF DIFFERENT TYPES OF PLANKTONIC BACTERIA AT PHENOMINAL SPEED. THESE ‘GOOD’ BACTERIA MULTIPLY AND CONSUME THE NEUTRIANTS (CONTAMINANTS) IN THE WASTE WATER – STARVING THE UNDESIRABLE SESSILE BACTERIA THAT BUILD UP AND CAUSE SLUDGE. RESULT – CLEAN PIPEWORK REDUCED ODOR AND PRE-TREATED SEWAGE TO THE SETTLING POND WITH FAR LESS SLUDGE BUILD UP. * * *

17 INLINE DIGESTION (ILD) SHARP REDUCTION IN FOUL ODORS AND CORROSIVE GASSES. DECREASED TOTAL SUSPENDED SOLIDS – INCREASING BIODEGRADABILITY. REDUCED TREATMENT PLANT SLUDGE. IMPROVED PIPELINE FLOW, REDUCED MAINTENANCE * * * * * NO NEED FOR POND AERATION. * OUTPUT WATER CAN BE USED FOR DIRECT IRRIGATION.

18 Position digestion enzyme packs At critical junctions in the system At this point water can be recycled for irrigation Reed beds will remove TSS and Dissolved N and P Waste in the pipelines is being digested by the enzyme prior to entry to the aeration ponds INLINE DIGESTION ENZYME PACKS WORKING IN THE UNDERGROUND SEWAGE SYSTEM.

20 FARM EFFLUENT TREATMENT THE ENZYME USED TO TREAT HUMAN WASTE IS THE SAME AS IS USED FOR CATTLE WASTE AT PRESENT WE ARE REDUCING DAIRY FACTORY EFFLUENT WITH A BOD VALUE OF mg/lt TO 10 mg/lt. EFFLUENT FROM FARMS AS WELL AS DAIRY PROCESSING PLANTS CAN BE TREATED. * * * * NO NEED FOR POND AERATION. * OUTPUT WATER CAN BE USED FOR DIRECT IRRIGATION.

21 FARM EFFLUENT TREATMENT NITROGEN FROM DAIRY/DAIRY FACTORY WASTE COMES FROM THE PROTEIN. CONSTRUCTED WETALNDS USING TALL FODDER GRASSES IS THE MOST EFFICIENT WAY TO REMOVE NITRATES AND PHOSPHATES AS IT DECOMPOSES IT COVERTS TO NITRATES – THEN NITROGEN GAS BUT THE PROCESS IS SLOW. * * * * DAIRY FACTORY MILK BY-PRODUCT IS REDUCED USING ENZYMES AND WETLAND FILTRATION IN A HIGHLY ALKALINE FORMAT.

22 WASTE WATER FROM DIARY FIRST TANK TO ENZYMATICALLY TREAT WASTE WATER – SIZE WILL DEPEND ON FLOW / VOLUME OF WATER PER HOUR. REED BED FILLED WITH PERMIABLE MATERIAL LIKE SAND AND GRAVEL. GROW N AND P ABSOBANT PLANTS LIKE CORN AND OTHER FODDER GRASSES. THIS ALSO ACTS AS A FILTER TO REMOVE ANY AND ALL SUSPENDED SOLIDS. GREEN FODDER PLANTS TO ABSORB ‘N’ AND ‘P’ EXIT WATER WITHOUT ‘N’ AND ‘P’ OR SOLIDS – USE FOR DIRECT IRRIGATION FARM OR DAIRY FACTORY EFFLUENT TREATMENT SCHEMATIC
