“…Rivers and streams water consequently turns brown, smelly and slimy. Often fish and other aquatic organisms get killed and local people are denied the availability of local water sources for domestic uses and fishing [21]. The aim of this study was to investigate POME pollution impact on quality of receiving surface water and agricultural soils in Abak Usung Idim, Abak Local Government area of Akwa Ibom State, Nigeria.…”

A field study was conducted to investigate palm oil mill effluent (POME) pollution impact on ground water quality and agricultural soils. Raw POME and two water samples were also collected from the downstream and upstream locations away from the effluent discharge point using 1 litre capacity container. This was found less than 100 m from the mill. Soil samples from the POME dumpsite as well as non-POME soil were collected. Temperature, pH, electrical conductivity (EC), salinity, total hardness, turbidity, sulphate, COD, BOD5, total dissolved solids (TDS), total suspended solids (TSS), dissolved oxygen, total alkalinity and percentage saturation for water samples were determined. pH, water holding capacity, total organic carbon (TOC), total organic matter (TOM), total nitrogen, available phosphorus, exchangeable cations: K, Na, Ca, Mg and cation exchange capacity for soil. Data obtained from the study were subjected to statistical analyses of variance (ANOVA). Significant variations exist in most of the physicochemical variables among the sampled parameters. Data for water samples were also compared with world health organization and Nigerian standard for drinking water quality. Most of these parameters indicated pollution but were below the standard limits for consumption. pH, EC, total hardness, turbidity, sulpahte, COD, BOD5, TDS, TSS, dissolved oxygen, total alkalinity, % saturation were all significant difference from each other. Soil pH, EC, TOC, total nitrogen, available P, TOM, Ca and exchangeable acidity were also all significant difference from each other. It is concluded that a strong move towards quality and environmental management through ecological improvement and cleaner technology approach within manufacturing industries in Nigeria is implemented.

“…The authors noted that the downstream section of the river being the receiving location of the waste POME was more polluted than other sections of the river. When POME is discharged into river waters, the water system turns brownish, smelly and slimy [5]. Consequently, fish and other aquatic organisms in the river are killed.…”

Physicochemical characteristics of soils from three communities (Umualumaku, Umeze II and Eziama) in Imo State, Nigeria, receiving application of palm oil mill effluent (POME) were investigated. Results obtained indicated that the soil sample from Umualumaku sampling station had the highest pH (5.25), conductivity (30.35 μs/cm), nitrate (50.73 mg/l), phosphate (10.10 mg/l), iron (5660.00 mg/l) and cadmium (4.20 mg/l), compared to the soil samples of the other two sampling stations (Umueze II and Eziama). It was observed that the raised concentrations observed in all the parameters investigated in the three sampling stations compared to the control samples was indicative of the fact that the raw POME was capable of impacting the soil. These results thus showed that raw POME is able to improve soil fertility and growth performance of crops if controlled application is practiced.

“…No matter how effective the method of processing, POME discharged from a mill is objectionable and could pollute streams, rivers, or surrounding land [15]. When discharged into water bodies it turns the water brown, smelly, and slimy and causes anoxygenation [16], and may kill fishes and other aquatic organisms thereby denying humans access to good water for domestic use [17]. Also, application of untreated POME on soil alters its physic-chemical properties, causing undesirable decreases in pH and increases in salinity.…”

Palm oil mill effluent (POME) is high strength wastewater derived from processing of palm fruit. It is generated in large quantities in all oil palm producing nations where it is a strong pollutant amenable to microbial degradation being rich in organic carbon, nitrogen, and minerals. Valorization and treatment of POME with seven yeast isolates was studied under scalable conditions by using POME to produce value-added yeast biomass. POME was used as sole source of carbon and nitrogen and the fermentation was carried out at 150 rpm, 28 ± 2°C using an inoculum size of 1 mL of 106cells. Yeasts were isolated from POME, dump site, and palm wine. The POME had chemical oxygen demand (COD) 114.8 gL−1, total solid 76 gL−1, total suspended solid (TSS) 44 gL−1and total lipid 35.80 gL−1. Raw POME supported accumulation of 4.42 gL−1dry yeast with amino acid content comparable or superior to the FAO/WHO standard for feed use SCP. Peak COD reduction (83%) was achieved with highest biomass accumulation in 96 h usingSaccharomycesspL31. POME can be used as carbon source with little or no supplementation to achieve waste-to-value by producing feed grade yeast with reduction in pollution potential.
