“…(1,070 mg/L), TSS (1,400 mg/L), total phosphorus (62.86 mg/L), orthophosphate (47.37 mg/L), total nitrogen (317 mg/L) and total organic carbon (493.82 mg/L) which were contrary to the discharge of the acceptable effluent imposed by the Department of Environment (DOE). It worsens the situation due to the use of corrosive chemicals for cleaning processes or wastewater treatment systems, as it contains heavy metals such as copper, molybdenum, zinc, chromium, nickel, arsenic, titanium, and vanadium (De Sena et al, 2009;Djogo et al, 2016). Djogo et al (2016) also confirmed that there was a substantial amount of indicator bacteria such as fecal coliform, fecal streptococcus, and total coliform found in meat processing wastewater.…”

Developing countries such as the Philippines suffer from a lack of policy development and implementation on wastewater treatment and discharge. Chlorella vulgaris is a microscopic green algae that has been employed in other countries for WWT due to its ability to simultaneously reduce pollutants and produce valuable biomass. However, challenges in technology adaptation such as differential efficiency depending on the location and wastewater types were encountered. Three liquid wastes of different origins—municipal (public market), agricultural (piggery effluent), and industrial (meat processing plant) wastewaters, were used to gauge the remediation potentials of C. vulgaris in a simple photobioreactor setup. Treated samples from municipal, agricultural, and industrial wastewaters showed microalgal growth rates of 0.2685, 0.1527, and 0.1809, respectively, along the 6-day treatment period. Post-intervention comparisons of treated vs. untreated samples revealed a lower electrical conductivity, total dissolved solids, chemical oxygen demand, nutrients (nitrate, ammonia, phosphate), and fecal coliform (MPN/100 mL) on treated samples. Moreover, all treated samples demonstrated relatively higher dissolved oxygen concentrations, denoting the photosynthetic activity by the microalgae. Therefore, Chlorella vulgaris could be harnessed for the remediation of different wastewaters in Nagcarlan, Laguna, Philippines to circumvent issues in water reclamation and degradation.

“…Almost half of the water consumed in the United States is used in raising animals for food. Most of the water is used for carcass washing, hair removal from hogs, cleaning and sanitizing of both equipment and facilities and finally, for cooling of compressors and pumps [4]. Accordingly, during the production or cleaning, fats and/or blood are becoming a part of the wastewater system.…”

A B S T R A C TThe emission of untreated or insufficiently treated wastewater is very common in developing countries and consequently has harmful effects on the environment. The aim of this study was to analyse 24 physico-chemical parameters in raw wastewater and effluent after tertiary treatment (denitrification and disinfection) derived from meat-processing plants in Serbia during four sampling campaigns conducted for one year. The biochemical oxygen demand (BOD 5 ) and chemical oxygen demand (COD) were measured at high concentrations up to 6,960 and 14,160 mg/L, respectively, indicating a large amount of uncollected blood, solubilized fat, urine and faeces in discharged wastewater. Required limits of emission in all samples according to the European and national legislation for most of the studied parameters were exceeded. According to the obtained results, there is an imperative need for pretreatment of wastewater from meat industry before discharging it into the sewer. The applied wastewater treatment improved the quality of water by reducing BOD 5 and COD values to 97.97 and 98.08%, respectively, while phosphorus removal efficiency varied from 15.29 to 68.48%.

“…[15][16][17] According to Ferreira et al, 18 the flotation sludge can be applied as raw material in the production of animal feed, as biomass for direct combustion, as organic material for composting and subsequent use as fertilizer, or disposed of in industrial landfills, the usual practice. de Sena et al 19 have evaluated the presence of trace elements, polycyclic aromatic hydrocarbons (PAH) and polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/PCDF) in these biosolids, proving that it could be safely landfilled and even applied as soil fertilizer, within the limits established by the European Union and the US Environmental Protection Agency.…”

Flotation sludge from the meat processing industry can be applied as biofuel in already existing plant-scale boilers. This biosolid is rich in oil and grease and has higher energetic content on a dry ash-free basis (22.74 and 27.71 MJ kg −1 ) than the wood-based fuel (16.62 and 16.16 MJ kg −1 ). Co-combustion trials were performed at a pilot-scale cyclonic combustor (100 kg h −1 ) and at an industrial flamotubular rotatory grate-fired system (6000 kg h −1 ), co-firing pre-dried and centrifuged flotation sludges (respectively) and wood at a mass ratio of 1:3. At a moisture content of 60.13 wt%, the lower heating value of the centrifuged sludge was 10.24% lower compared to wood, thus reducing it to at least 40 wt% would be advisable to obtain energy gains in the industrial plant when operating the co-combustion. The emissions were evaluated and compared to emission standards, including the characterization of polycyclic aromatic hydrocarbons and polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (given as Toxicity Equivalent Factors at O 2ref = 7%), which have not yet been reported. The 16 target polycyclic aromatic hydrocarbons were identified at pilot and plant scales (0.582 ± 0.143 μg Nm −3 and 0.602 ± 0.506 μg Nm −3 , respectively) being lower than the Danish reference standard (5.0 μg Nm −3 ). The polychlorinated dibenzop-dioxins and polychlorinated dibenzofurans concentrations were 0.0004 ± 0.0001 ng Nm −3 at pilot scale and 0.3617 ± 0.1310 ng Nm −3 at plant scale, both below the Brazilian and American standards but differed greatly between the scales, requiring further investigation since their formation can occur due to combustion and postcombustion conditions.
