“…Similar observations were made in previous studies conducted in Rivers State, in Bayelsa State, and Delta States. 13,[21][22][23][24][25][26] Some studies have reported that at low alkaline levels, water pipes and fixtures corrode, thus leading to the release of potentially harmful metals like copper and lead from the plumbing system into the drinking water. This action alters the aesthetics and taste of water (bitter or metallic taste) and may erode the enamel of the teeth of members of the community who consume it.…”

Background: Access to potable water is a human right that plays a significant role in maintaining health and sanitation. Its limited supply in oil-producing areas has been variously linked to diverse pollutants in crude oil-producing communities, in Nigeria’s Niger Delta region. This cross-sectional study analysed and compared the physico-chemistry of drinking water sources in high and low crude oil-producing communities in the Niger Delta region between January to February 2023. Methods: Water samples were collected from a total of 28 samples from geo-referenced points in 10 communities. Analysis was done using the approved APHA and ASTM methods and assessed based on the recommended World Health Organization (WHO) permissible limits of detection for water quality. Data were analyzed using the statistical package for social science (SPSS) version-26. Test of significance and associations were set at p<0.05 and 95% confidence level. Results: There were significant differences in the mean concentrations of water alkalinity, chromium (Cr), barium (Ba), total petroleum hydrocarbons (TPH), polyaromatic hydrocarbons (PAH), and TOG in water sources of the high and low oil-producing communities. Other mean concentrations of the analysed physicochemical parameters were found to be within normal limits for pH, salinity, turbidity, EC, total dissolved solids (TDS), total suspended solid (TSS), DO, and BOD, below the limit for alkalinity, chemical oxygen demand (COD), nitrate (NO3), ammonia (NH3), sulphate (SO4), bicarbonates (HCO3), chromium (Cr), copper (Cu), iron (Fe), TPH and above recommended limits for temperature, PAH and TOG. Conclusions: The study showed that both high and low oil-producing communities had contaminated ground and surface water sources, although the high oil-producing areas were much more polluted. It is, therefore, necessary to enhance the national oil pollution regulatory mechanisms and remediation activities in heavily polluted sites to safeguard community water sources and protect human health.

“…According to Amiri et al [26] the EC finds higher level correlation significance with many of the water quality parameters, like TDS, chlorides, total alkalinity, sulphates, total hardness and magnesium. Similarly, Chikwe et al [34] identified that all the parameters are more or less correlated with others in the correlation and regression study of the physiochemical parameters of ground water.…”

Introduction: The discharge of produced water into the aquatic environment presents a risk to the environment. This is a form of pollution and may release toxicants that are highly noxious to sensitive marine species even at low concentrations, which causes bio-degeneration/transformation and biodiversity loss. Research Gap: There are insufficient literatures on extensive monitoring of the physicochemical and microbial characteristics of produced water. Existing literatures concerning analysis of treated and untreated produced water are not comprehensive with respect to number of physicochemical variables analyzed. Aim: To ascertain if the physicochemical properties and microbial population of produced water were within acceptable regulatoy specifications. Place and Duration of Study: The study was conducted in the Federal University of Petroleum Resources, Effurun, Delta State, Nigeria from July, 2021 – April, 2022. Methodology: Electrical conductivity, dissolved oxygen, pH, temperature, turbidity, total petroleum hydrocarbons, nitrates, phosphates, sulphates and others were assessed using standard methods. Microbial counts were carried out for total heterotrophic bacteria and hydrocarbon utilizing bacteria using the pour plate method. Results: Values obtained for some key physicochemical parameters monitored in the produced water are as follow: pH (8.10±0.03 for untreated and 8.27±0.01 for treated); electrical conductivity (35700±11 µs/cm for untreated and 41600±17 µs/cm for treated); total dissolved solids (22848±14mg/l for untreated and 26629±9mg/l for treated); dissolved oxygen (2.05±0.01mg/l for untreated and 4.23±0.03mg/l for treated); biochemical oxygen demand (28.90±0.7mg/l for untreated and 18.4±0.1mg/l for treated); phosphate (2.05±0.01mg/l for untreated and 4.23±0.03mg/l for treated); nitrate (54.82±1.9mg/l for untreated and 50.21±0.9mg/l for treated); total hydrocarbon content (118.00±0.00mg/l for untreated and 34.00±0.00mg/l); total heterotrophic bacteria (4.1e+04 CFU/ml for untreated and 2.8e+04 CFU/ml for treated); and hydrocarbon utilizing bacteria (2.44e+03 CFU/ml for untreated and 1.58e+03 CFU/ml for treated). Statistical analysis of the produced water showed varying forms of correlation between physicochemical parameters of untreated and treated produced water. Conclusion: It is important to assess properties of produced water before disposal into aquatic environment as chronic impact associated with long-term exposures may pose potential ecological risks.

“…Basically, the total water consists of water in the cavities of the subsurface formations and injected water which has a dual purpose of enhancing the recovery of oil and gas and maintaining pressure in the reservoir [ 9 , 10 , 11 ]. For gas production wells, PW also consists of condensed water [ 12 , 13 ]. Inclusive of water, PW is also a complex mixture of soluble and insoluble high molecular weight hydrocarbons (aromatic and saturated), heavy metals, anions, and other impurities [ 14 ].…”

Membrane Bioreactors for Produced Water Treatment: A Mini-Review

et al. 2022

View full text Add to dashboard Cite

Environmentalists are prioritizing reuse, recycling, and recovery systems to meet rising water demand. Diving into produced water treatment to enable compliance by the petroleum industry to meet discharge limits has increased research into advanced treatment technologies. The integration of biological degradation of pollutants and membrane separation has been recognized as a versatile technology in dealing with produced water with strength of salts, minerals, and oils being produced during crude refining operation. This review article presents highlights on produced water, fundamental principles of membrane bioreactors (MBRs), advantages of MBRs over conventional technologies, and research progress in the application of MBRs in treating produced water. Having limited literature that specifically addresses MBRs for PW treatment, this review also attempts to elucidate the treatment efficiency of MBRs PW treatment, integrated MBR systems, general fouling, and fouling mitigation strategies.
