“…Similarly, P. australis planted HSSFCW showed better removal of total phenolic compounds (69.1% removal) (Gomes, Silva, Albuquerque, Simões, & Stefanakis, 2018). On the other hand, T. latifolia plant showed a high phenol removal efficiency (99%-100% removal) in VSSFCWs, while treating secondary refinery wastewater effluents (Mustapha, Bruggen, & van;. P. australis showed a better removal efficiency (28.6% for TDS, 94.4% for TSS, 79.8% for turbidity, 93.7% for BOD, and 82.6% for COD) than that of latifoila while treating wastewater in SFCWs (Shahamat, Asgharnia, & Kalankesh, 2018).…”

This article presents an update on the research and practical demonstration of wetland treatment technologies for wastewater treatment. Applications of wetlands in wastewater treatment (as an advanced treatment unit or a decentralized system) and stormwater management or treatment for nutrient and pollutant removal (metals, industrial and emerging pollutants including pharmaceutical compounds and pathogens) are highlighted. A summary of studies involving the effects of vegetation, wetland design and operation, and configurations for efficient treatment of various municipal and industrial wastewaters is also included.

“…Therefore, for the last 20 years, wetlands have been applied to industrial wastewater treatment [73]. There are many examples and many reviews of successful application of wetlands for oil refinery wastewater treatment [74][75][76][77][78][79][80][81][82][83]. However, certain climatic conditions are required to sustain the wetland systems, e.g., Wang, et al [84] showed that wetlands do not function well during the cold season.…”

Pitfalls of Wastewater Treatment in Oil Refinery Enterprises in Kazakhstan—A System Approach

The present article is an assessment of wastewater treatment processes in the oil refinery sector in Kazakhstan by comparing relevant experience of developed and developing countries. The legislation in this sphere, the treatment methods, the discharge process and the effect on the environment were evaluated following international and national regulations. In our study, the wastewater systems in three factories in Kazakhstan were assessed. Results show that, even though the environmental regulation in Kazakhstan promotes the polluter pays principle and follows the World Health Organization (WHO) recommendations, the oil refinery plants in Kazakhstan still contain exceeding concentrations of pollutants in their effluents. One issue is that the local legislation allows disposal of wastewater to natural or artificial ponds as long as the concentrations of pollutants in effluents are less than the already existing concentrations in the pond. Consequently, the factories can use ponds with an initially high concentration of contaminants. The high initial concentration of pollutants in the pond water is due to wastewater discharged before the implementation of current environmental regulations. This issue in the current legislation leads to the situation where there is no incentive for efficient wastewater treatment. The national law also lacks regulations regarding which methodology should be used to assess the pollutants in the wastewater. Thus, the control by national environmental office for each enterprise is negotiated separately between the factory and the governmental body. This gives the factory a strong position to define the parameters assessing the effluents. This has led to none of the factories measuring, e.g., heavy metals in discharged wastewater. Total petroleum hydrocarbons (TPH) concentration in wastewater is often exceeded at each factory and there is no analysis done for different hydrocarbon fraction. To overcome the issues described in the present study, we strongly recommended a unified and transparent methodology for the country’s oil refinery industry to assess important pollutants in discharged wastewater.

“…4a, 4b) by the macrophytes, with Eicchornia crassipes having the highest efficiency for chloride removal (780 mg/l to 107 mg/l) and Salvinia molesta having the highest efficiency for phenol and ammonical nitrogen removal (13 mg/l to 3 mg/l and 87 mg/l to 14 mg/l, respectively). The high phenol removal efficiency could be attributed to the fact that the presences of the macrophytes favor the growth of some microorganisms which help in the degradation of phenol (Mustapha et al, 2018;Suyamud et al, 2018 ammonical nitrogen and chloride % reduction by the macrophytes is attributed to the fact that but nitrogen and chloride are needed for plant growth although chloride are needed in minute quantity, so there as on for the high chloride removal efficiency could be due to the fact that the concentration of chloride in the wastewater was minute (Han et al, 2018).…”

The production of dye is usually associated with several intermediate products and waste which are usually toxic and bio-hazardous and often disturb the environmental equilibrium. The present study is aimed at selecting macrophytes with the highest efficiency in the remediation of wastewater generated from dyeing activities. The test macrophytes were introduce into three different troughs for each plant containing 100% wastewater, 50% wastewater and control (100% borehole water). After 21 days the macrophytes were removed for further analysis. The reduction efficiency, Heavy metal bioconcentration and bio translocation factor of the macrophytes was determined. The result obtained shows that the test macrophytes improved the pH but were not able to improve the color of the wastewater. Lemna minor have the highest reduction efficiency for BOD, COD, Oil, and Grease while Pistia stratiotes have the highest reduction efficiency for TDS and TSS, Eicchornia crassipes have the highest reduction efficiency for Cland Salvinia molesta have the highest reduction efficiency for phenol and ammonical Nitrogen. All macrophytes recorded high reduction efficiency for heavy metal removal but Pistia stratiotes and Eicchornia crassipes had the highest bioconcentration and translocation. These macrophytes should be introduced to the local dye users as a costless and environmentally friendly way of treating wastewater resulting from dyeing activity.
