“…According to [10] an alternative way can be done to reduce the levels of organic substances using anaerob-aerobic combination biofilter that has been able to reduce BOD content of 72.56-91.65% from 1198.5 mg / l to 782 , 6 mg / l. Research conducted by [10] lowers BOD levels of RPH waste water by passing waste water on plastic bottle media that serves as a place to attach microbial aerobes and anaerobes and form biofilter that can lower BOD levels. Mean of COD content in wastewater at RPH 2200 mg / l, this result is higher than standard quality that has been determined, but this result is higher than research of [1] that is 1862 mg / l. According to [7] COD levels in waste water at slaughterhouses in the study ranged from 1750 to 5900 mg / l. High levels of COD show the high amount of oxygen needed to oxidize all the organic and inorganic chemicals in the wastewater sample. In addition to reducing the COD value in waste water can be done with microbes, according to [9] states that by embedding the microbes in gravel to form biofilter in aerobic and anaerobic conditions can reduce BOD, COD and TTS up to 65% in BOD and 29.21% in COD.…”

The purpose of this research is to know the contamination of waste water that happened in slaughterhouse (RPH) city of merauke. Data were obtained based on surveys and field observations and the sample used was RPH water waste each in repeat as many as 6 replications. Data analysis was done descriptively by comparing the result obtained with the standard of quality which have been determined. The results showed that the contamination of waste water all exceeded the quality standard except at pH value. The ALT content of wastewater in RPH 2790 x 104 and contains E. Coli and Salmonella microbes. The high content of BOD, COD, TTS, Ammonia and microbial contamination is thought to be due to the absence of wastewater treatment installation (IPAL) at RPH in accordance with the standard. Proper handling of ammonia waste can reduce the amount of carbon in the atmosphere.

“…The total solids and volatile solids concentration contributes in the process of anaerobic digestion as it reduces water level which results to boost microbial activities. This results in increase in the biogas generation geometrically 17‐21 . There are few biogas models based on mass balances in anaerobic digestion process taken for dry organic matter and nitrogen.…”

Multiple parameter comprehensive index by fuzzy logic is an innovative approach toward environmental indexing. An attempt was carried out to express strength of municipal wastewater and sludge considering their potential for biogasification in terms of wastewater comprehensive index (WWCI) and sludge comprehensive index (SCI), respectively. Both these indices were calculated using fuzzy multiple criteria decisions making (FMCDM). Further biogas was predicted using these WWCI and SCI by multiple linear regression. A significant relation was found in suspended solids concentration of influent wastewater and digester feedstock with WWCI and SCI, respectively. Considering this linear relation, an empirical equation was developed consisting WWCI and SCI giving biogas, which was found a user friendly and precise over established biogas prediction models. As both of these indices will be obtained simply by measuring suspended solids concentration by digital inline meter at wastewater treatment plant there will be no any need to practice laborious sampling, characterization, and calculations.

“…Therefore, the use of intentionally cultivated energy crops may be characterized by low energy efficiency and significant greenhouse gas emissions per unit of energy obtained. Therefore, the focus has recently shifted to the energy use of animal waste [5][6][7][8]. Thus far, the most common way to utilize such materials is thermal processing.…”

The Effect of the Addition of a Fat Emulsifier on the Amount and Quality of the Obtained Biogas

et al. 2020

Slaughterhouse waste management is an important technological, economic, and environmental challenge. Recently, more and more attention has been paid to the possibility of obtaining biogas from waste generated by slaughterhouses. The aim of the paper was to examine the effect of an emulsifier addition in the form of a carboxymethyl cellulose solution to create animal waste fermentation media based on the quantity and quality of the generated biogas. The adopted research goal was achieved based on a laboratory experiment of methane fermenting poultry processing waste. The waste was divided into two fractions: soft (tissue) and hard (bone). A fat emulsifier in a concentration of 1%, 2.5%, 5%, and 10% of fresh weight of the substrate was added to each substrate sample made from the above fractions. The emulsifier used was a 55% carboxymethyl cellulose solution, since this emulsifier is most commonly used in food production. The experiment was conducted in order to determine how the addition of an emulsifier (55% carboxymethylcellulose solution) affects the hydration of fats during methane fermentation, as demonstrated on poultry slaughterhouse waste. The samples were subjected to static methane fermentation, according to the methodology of DIM DIN 38414(DIN Deutches Institut für Normung). The experiment lasted 30 days. The total amount of biogas obtained after fermentation was 398 mL·g−1 for the soft fraction and 402 mL·g−1 for the hard fraction. In the case of the soft waste fraction, the addition of carboxymethylcellulose at 1% of the mass to the biogas process increased the amount of obtained biogas by 16%. In the case of the hard fraction, no effect of the addition of emulsifier on the total amount of biogas obtained was identified. In each case, the biogas from substrates with added emulsifier contained less methane and slightly more carbon. The emulsifier added to the soft fraction of slaughterhouse waste from poultry processing allowed cutting the process of methanogenesis by over 50% while maintaining the efficiency of biogas production. In the case of biogasification of bone tissue, no unambiguous effect of the addition of emulsifier on the improvement of process efficiency was identified.
