“…Additional research shall be done after the community of microorganisms will be well developed. For an effective wastewater treatment, a particular attention shall also be paid to earthworm density -15,000 specimens/m2 also, the use for bedding and filter media also have effects on the establishment of microbial biofilms and the microbial community structure within the vermifilter and the treatment performance [11]. For an efficient wastewater recycling, the vermifilter was connected to a greenhouse, where some vegetables and decorative plants are grown.…”

The current article presents an innovative technical solution for sustainable management of septage, via a vermifiltration system, in the Republic of Moldova. A technical description of the main components of a demonstration model that was implemented at a household level is presented. The results from the model show an 98.85% reduction of ammonia content, 49,21 % CODMn (an indicator of degradation of easily degradable organic substances) and 85,28% of CODCr (showing degradation of hardly degradable organic substances). Considering the fact that the concentration of ammonium in the effluent was considerable reduced, while that of nitrate nitrogen remained rather low, it was assumed that the activity of earthworms was rather limited, probable the microorganisms, interacting symbiotically and synergistically with earthworms not being well developed in the vermifilter bed. The study suggests that the vermifiltration technology can provide a sustainable wastewater management solution and its application can be promoted in certain settings such as schools and kindergartens in Moldova. However, good insulation should be considered to avoid the freezing problems during winter while the odor nuisance in the septic tank can be reduced by adding lactic acid bacteria can also be applied.

“…Krishnasamy et al [47] give an overview of the vermifiltration process for liquid waste treatment and they recommend adjusting key design parameters to different contexts and climates, such as worm species, hydraulic retention time (HRT) or hydraulic loading rate (HLR). Arora & Saraswat [48] focus on factors affecting the performance of vermifilters for wastewater treatment under different scenarios related to the treatment mechanism. Other studies consider different kinds of biofilters (employing earthworms and plants) for wastewater and organic waste treatment to perform a comparative study focusing on aspects such as nitrogen and ammonia reduction [49,50].…”

“…Thus, prolong utilization of water and soil resources would necessitate the application of sustainable techniques such as green technology. Green technology is a natural process that provide high quality outcomes without compromising on environmental sustainability [24]. They serve as alternative method for the treatment of wastewater.…”

“…Several types of green technologies have been applied for the remediation of polluted sites. Examples include but not limited to phytoremediation, bioremediation, biostimulation, bioaugmentation, natural attenuation, constructed wetlands, vermifiltration, nanotechnology, membrane filtration, and microbial fuel cells [19,21,[24][25][26][27]. Phytoremediation is a cost-effective, plant-based technique of environmental remediation that uses the ability of plants and indigenous microorganisms in the rhizosphere to treat different types of contaminants [26].…”

Crude Oil - New Technologies and Recent Approaches

Cleaner production is the key to environmental sustainability. Conversion of crude oil to various beneficial products is responsible for the contamination of air, water, and soil which are harmful to human, plants, animals, public health and the environment. Adequately treating produced water is beneficial for irrigation, wildlife consumption, industrial water and for domestic purposes. Therefore, green technology for treatment of crude oil processed water would provide the environmental friendliness needed for prolong utilization of our natural resources. Hence, the aim of this book chapter is to investigate the potentials of constructed wetland as a promising, effective and environmentally friendly alternative for secondary petroleum refinery wastewater treatment. Planted and unplanted mesocosm scale experiment with real secondary refinery wastewater was used for the purpose of the study. The parameters investigated were temperature, pH, dissolved oxygen, electrical conductivity, total suspended solids, carbon oxygen demand, total petroleum hydrocarbon and oil and grease. The results revealed that Typha latifolia planted VSSF CWs effectively treated organic contaminants in secondary refinery wastewater with a better performance than the unplanted control VSSF CWs. The chromatographs for wastewater and T. latifolia samples showed a hydrocarbon distribution between n-C9 to n-C24 indicating abundance of lower weight hydrocarbon contamination.
