Water Pollution Remediation Techniques with Special Focus on Adsorption

Any Material, having structure in nanometer scale with at least one dimension is recognized as Nanomaterial (NM). These Nanomaterial (NMs) have vast variations in their elemental composition; which may be formed by single element viz. Gold, Silver, Iron, Carbon etc. or by the combination with Oxygen or Sulphur as Oxides & Sulphides viz. Iron oxide (Fe2O3), Copper Oxide (CuO) or Cadmium Sulphide(CdS),etc. Among the single elemental forms, the Carbonaceous Nanomaterials(CNMs) are identified as nanosized allotropic forms of Carbon having different structures like Nano rods, Nano tubes, Nano ring, Nano sphere, and Nano sheets mostly with sp2 carbon atoms. In past decades, Carbonaceous Nanomaterials(CNMs) have gain interest of researchers due to their biocompatibility, non-toxicity and unique surface to volume properties, etc. their easy tunable features are found advantageous for their utilization in wide range of applications. Further, owing to their specific mechanical strength, conductivity, surface activity and many more beneficial features, they have vast range of applicability in electronic, biomedical, energy storage & conversion, catalysis and remediation of environmental pollution. Present paper briefly describes about the types of Carbonaceous Nanomaterials (CNMs) with emphasizing their use in the remediation of Water Pollution. With the growing development of Nanotechnologies, use of CNMs may play a significant role in remediation of Water Pollution. KEYWORDS: Carbonaceous Nanomaterials(CNMs), Water Pollution, Remediation of Pollution.

The Ideal

Groundwater is widely distributed and stability changed.It is the ideal drinking water with good quality and easy application.As well as, it is an important water supply source of the life, industry and agriculture.However, groundwater pollution can't be ignored in China.In this paper, groundwater pollution,groundwater vulnerability evaluation and groundwater water pollution remediation technologies are reviewed through reading a lot of theses in China and other countries. The groundwater vulnerability evaluation of DRASTIC and based on the GIS technology are mainly introduced. According to the evaluation results, appropriate pollution remediation technologies are taken, so as to protect and repair groundwater. I hope this paper can provide some theoretical suggestions for the sustainable development of groundwater in China.

The Nakdong River

The Nakdong river estuary in South Korea has two important functions: first, remediating water pollution from the Nakdong river; second, mitigating the risk of disaster caused by waves from the open sea. The two functions of the Nakdong river estuary have been continuously threatened due to constant development pressure. This short note tries to investigate the non-market value of the water pollution remediation and disaster risk mitigation functions. For this purpose, 1000 households throughout the country were randomly selected, and a choice experiment (CE) survey of them was implemented in September 2017. The two attributes considered here are water pollution remediation and disaster risk mitigation. An increase in the yearly income tax was also considered as an attribute. The results of applying the CE approach show that the non-market values of a 1%p increase in the water pollution remediation ability and a 1 m decrease in the wave height of the estuary are KRW 105 (USD 0.09) and KRW 501 (USD 0.44), respectively, per household per year. These figures can be used to establish and execute marine spatial planning for the estuary.
