COSTS of TREATMENT METHODS for WASTES

AEROBIC PROCESSES are VERY EXPENSIVE, AS SEEN IN EVERY SEWAGE TREATMENT PLANT WORLDWIDE, with :

OPERATION COSTS CAN BE RELATIVELY HIGH for the ACTIVATED SLUDGE because OF THE ENERGY REQUIRED

ANAEROBIC PROCESSES CAN BE LESS EXPENSIVE, ESPECIALLY WITH ANIMAL WASTES WHICH ARE MUCH MORE CONCENTRATED than SEWAGE, and ALSO HAVE A MUCH SMALLER VOLUME

EVALUATION of WASTE AND WASTEWATER TREATMENT METHODS

SO IT is NOT SURPRISING at all THAT IT is STILL LOOKED DOWN UPON by EVERYBODY

SEWAGE CONTAINS LESS THAN 1% (repeat one percent) of ORGANIC WASTES THAT CREATE ALL the PROBLEMS CONNECTED WITH the FACT THAT PEOPLE WANT to LIVE ON TOP OF ONE ANOTHER

WHAT a WASTE TREATMENT PLANT DOES is TO CONVERT the MINUTE QUANTITY of ORGANIC POLLUTANTS into INORGANIC POLLUTANTS of ANOTHER KIND, and SHIFT THEM to ANOTHER SITE to CONTINUE the POLLUTION!

BUT THERE is NO REASON WHY the HUGE VOLUME of WASTEWATER SHOULD BE SENT to ONE SPOT WHERE NOBODY WANTS IT NEAR THEIR OWN BACKYARD

TOTAL TREATMENT OF ALL WASTES

ON INTEGRATED FARMS ALL LIVESTOCK WASTES ARE NOT ONLY TREATED COMPLETELY but ALSO ECONOMICALLY as well as ECOLOGICALLY

ON INTEGRATED FARMS ALL LIVESTOCK WASTES ARE NOT ONLY TREATED COMPLETELY but ALSO ECONOMICALLY as well as ECOLOGICALLY

THE TOTAL TREATMENT is ECONOMIC BECAUSE IT PRODUCES LIVESTOCK, FISH and CROPS at THE LOWEST POSSIBLE COSTS as FOODS and FEEDS

IT is CLEAN BECAUSE IT DOES NOT USE TOXIC or OTHER AGROCHEMICALS to KILL ANY ORGANISMS

REUTILISATION of ALL BY-PRODUCTS

THE RESOURCES from the LIVESTOCK WASTES are DIVIDED INTO THREE:

THE SLUDGE STAYS INSIDE the DIGESTER to ACT AS AN EFFECTIVE ANAEROBIC SLUDGE BLANKET to SLOW DOWN THE MOVEMENT of THE SOLIDS in THE WASTES

THE SYSTEM ITSELF HAS OTHER WASTES from THE BASINS, PONDS, DYKES, and FROM PROCESSING of THE FARM PRODUCE, and THEY CAN BE USED DIRECTLY as LIVESTOCK FEEDS

GROUP DISCUSSION

TOTAL RECYCLING of FARMING and AGRO-INDUSTRIAL WASTES

BIOGAS ENERGY is USED for 3 FARMING PURPOSES:

THE EFFLUENT CARRIES its SHARE OF NUTRIENTS from DIGESTER to BASINS /PONDS where THEY HELP GROWTH of PLANKTON as FEEDS for POLYCULTURE of FISHES

CROP RESIDUES are 40-50% of THE BIOMASS PRODUCED, and SHOULD BE TOTALLY USED on SITE, with OR without MICROBIAL PROCESSING, & as MANY TIMES as POSSIBLE
