Environmental Impacts of the liquid waste from Assalaya Sugar Factory in Rabek Locality, White Nile State, Sudan

Abstract

The study aimed to assess the environmental health impacts of the liquid waste from Assalaya Sugar Factory, the efficiency of the existing Assalaya effluent treatment plant, the dilution factors available in the White Nile to gather with wastewater environmental impacts. A descriptive cross-sectional focused on the Factory and its neighborhoods. Four hundred and thirty two out of 3931 households were statistically determined as the sample size, the individual samples were picked using multi-stage stratified method 432 households selected as sample size. Data were collected by using structured questionnaires, field observations, laboratory analysis and interviewing the concerned and affected persons. The effluent load discharged from the factory into the Al -jassir canal at the White Nile was analyzed for BOD, COD, pH, PO4, TDS, TSS, Turbidity, Color, and flow rate.The Data were processed by using the Statistical Package for Social Science (SPSS) version 16, Chi-square test, test associations and office excel 2007. The study showed that Eighty one percent of the households used the surplus irrigation canal as a source for water supply. 64% of the respondents suffered from diarrhea, vomiting and allergic diseases, the rather low rate of water consumption and the bad quality of water consumed were reflected adversely on hygiene and consequently increased water related diseases. The study concludes that always or sometime 49.5% of the water collectors were children and used animals and plastic containers for water collection and transportation. The conducted laboratory water analysis revealed that the average concentrations of PO4, COD and BOD of the raw wastewater produced by Assalaya Sugar Factory were 4260, 3800 and 1500 mg/l, respectively, these values were above the WHO recommended concentrations for the disposed treated effluent (2, 250 and 30 mg/L respectively). As to physical analysis; the turbidity on the average was higher (540 NTU) and the color was (854 TCU) also high.

The Environmental Impact of the Sugar Industry Waste in Sudan

“…This seems to indicate that the sugar industry wastewater in Sudan is discharged without treatment that mediates the reproduction of parasites. The result is supported with the ndings of studies conducted in Sudan on analysis the wastewater of the Assalaya sugar factory (Mohamed, et al, 2017;Ahmed, et al, 2017). It also went with same line of the ndings of a study conducted in Ethiopia on treatment of sugar industry wastewater with ferrous material (Sahu, 2019).…”

“…In a study conducted in the Assalaya, water related disease (i.e. vomiting, diarrhea and allergic) were observed among the community used the surplus irrigation canals that affect by the factory e uences (Ahmed, et al, 2017). This might be due to the lack of health awareness of the villages around the sugar industries.…”

Environmental Pollution from Cane Sugar Factories: A Study of Chemical Features Variations in the Wastewater

“…There is very little research on the topic in the area. The available research highlighted the problem of environmental health impacts of the wastewater in the study area (Ahmed et al, 2017). The researchers understand that the sugarcane factory has an important role and contribution to the national economy; nevertheless, the study analysis demonstrates the chemical features variations in the wastewater produced by the Assalaya sugarcane factory, which affects the society and development in the study area.…”

“…Disposing of wastewater in the ambient environment creates a suitable ground for chemical and microbial contamination in downstream areas and drinking water (Wang et al, 2017). This pollution is a modification in water's feature, making it unwanted, unsafe, and malevolent for human and animal health (Ahmed et al, 2017). The wastewater discharged from sugarcane processing has a significant role in altering the chemical characteristic of water and causing severe issues in the ambient environment (Marinho et al, 2014;Comwien et al, 2015;Sahu, 2016;Anastopoulos et al, 2017;Galvis et al, 2018).…”
