Comparative Characterization of Water Quality of Brari-Nambal La goon of Dal Lake Before and After Kashmir Floods

Abstract This work aims to present the hydrochemical mechanisms describing the system of the Euphrates River before and after mixing with groundwater from the springs of Hijlan (western Iraq). Continuously, the data generated from these springs' water have been adapted to provide an updated assessment for future water therapeutic purposes. Physicochemical characteristics of water in the mixing plume of Hijlan Creek and the Euphrates indicate the multi Hydrochemical plumes as revealed by the spatial variation of important parameters related to the ecological parameters including K+, Na+, Ca+ 2, Mg+ 2, HCO3−, SO4 − 2, Cl−, NO3−, PO4 − 3, Pb, Zn, Cd, Fe, Mn, Temp, DO, BOD5, H2S, Turbidity, EC, pH, and TDS. The re-aeration (k2) and de-oxygenation rate (k1) coefficients, as well as the self-purification factor (f) of the mixing plume, are 0.51 sec− 1, 2.03 sec− 1, and 0.25, respectively. The Cl− concentration in the confluence zone changes, due to the chloride content mixing rates of 7.1% and 92.9% for Euphrates and Hijlan creek water, respectively, with water discharge of 316,224 m3/day and chloride load discharge of 420 tons/day. The assessment of the water quality indicates unsuitability for aquaculture purposes. However, the water can be used for therapeutic purposes and to cure multiple diseases.

In the field of research and consequent elaboration of biopolymers it has been growing in the last decade, either due to the hardening of the environmental legislation of each country or due to ecological awareness, in any case the term biopolymer is quite broad, these being used as material premium in medicines, food supplements and of course in the production of bioplastics. Since the topic of interest is the comparative characterization of biopolymers using starch extracted from two different cereals, oats and rice, using the alkaline technique with NaOH treatment and the milling technique, assuming that the starch extracted from the Oryza sativa cereal presents chemical characteristics, geometric and mechanical superior in both techniques used unlike the polymers made with Avena sativa starch. These results suggest that the starch quality of each cereal is relevant for the production of biopolymers [1]. The commercially significant properties of starch, such as its mechanical strength and flexibility, depend on the strength and character of the crystalline region, which depends on the ratio of amylose and amylopectin.

The Impact

Abstract Sewage discharge is considered to be the primary source of viral contamination in aquatic environments. This study was conducted to evaluate the impact of El-Rahawy wastewater on the water quality of the Rosetta branch of the River Nile (Rosetta River Nile) through detection of astrovirus (AstV) and norovirus (NoV) in the water and sediments of both sites. For this purpose, we collected 72 wastewater and 12 sediment samples from El-Rahawy drain, and 12 river water and 12 sediment samples from Rosetta River Nile before and after mixing with El-Rahawy wastewater between April 2017 and March 2018. AstVs and NoVs were identified in wastewater (40.2% versus 25%), El-Rahawy sediment (41.6% versus 20.8%), river water after mixing with wastewater (25% versus 16.6%), river water before mixing with wastewater (8.3% versus 0%), river sediment after mixing with wastewater (16.6% versus 8.3%), and no viruses were found in river sediments before mixing with wastewater. AstV genogroup B and NoV genogroup GI were the most frequently detected genotypes in the analyzed samples, with a peak incidence in the winter months. Increasing detection rates of both viruses in El-Rahawy drain samples and river water taken from the Rosetta branch after receiving El-Rahawy wastewater reflect the impact of this drain on the water quality of this stretch of the River Nile.

Large-scale controlled planting of water hyacinth has become one of the most important measures of Dianchi Lake’s treatment in the “12th Five-Year Plan”. This paper firstly introduced the present situation of large-scale controlled planting of water hyacinth in Dianchi Lake. The water quality of Caohai and Waihai of Dianchi Lake were compared before and after the project of planting water hyacinth. This paper concluded that the effects of large-scale controlled planting of water hyacinth on the ecological restoration of Caohai lake were outstanding. The area of controlled planting could be spread among other water areas of Dianchi lake where is suitable for the growth of water hyacinth in the future, and water hyacinth will pay a greater role in the ecological treatment of Dianchi Lake.

Cow Bone

Characterization of Environmentally friendly materials used as wastewater treatment material has been studied in order to compare the quality of wastewater in Chiang Mai, Thailand on two types of treatment materials, which are cow bone char (CBC) made from Thai cow bone char cleaned and calcined at 850๐C and the a mineral called “zeolite” (ZLT) bought from Kamthiang market, Chiang Mai. The physical characteristics of both types of materials indicate that the CBC has a higher density than the ZLT but has lower pore volume than the ZLT. The effect of density on the water quality improvement was showed that CBC was a suitable type of wastewater treatment material because their high density can fix them in the batch system.
