Grey water

This paper aimed to determine the grey water footprint (GWF) of geothermal water resources and to investigate the effect of biochar adsorption on grey water footprint in Southeastern Turkey. In this paper, GWF has been calculated in terms of iron (Fe), arsenic (As), manganese (Mn), boron (B), and chrome (Cr) concentrations for fifteen observation geothermal resources located in Southeastern Anatolia Region. In this study, a new approach based on the GWF was developed in order to determine the geothermal water pollution.

Analysis of samples which were taken at Yangshan port in China in 2011, 2012 to assess the level of heavy metal pollution of heavy metals and petroleum hydrocarbon with two main purposes; the first is to evaluate the main pollutants and their pollution level; the second is to evaluate the impact of operations on the port to environmental quality. The application of Grey clustering model to assess heavy metals and petroleum hydrocarbons shows that the heavy metals and petroleum hydrocarbons in sea water at Yangshan Port was at grade I.

This research focus on to presents of the MQL parameters optimization approach in which the multi-response outputs based on Taguchi's L9 orthogonal array method is used. During the turning AISI-1045 steel, the cutting temperature, the maximum of tool wear, and the surface roughness were measured. The MQL parameters which are ratio of soluble lubricant and water, pressure of spray head, flow volume of emulsion was simultaneously optimized by taking the multi-response outputs using Taguchi based grey relational analysis (GRA) into consideration.

Water availability for agriculture in the country is projected to go down to around 70 per cent by 2025 which undoubtedly will limit the country’s capacity to provide expected food security. Under this water crisis scenario, grey water - an alternate source to supplement the overall water use is the need of hour. Characterization of grey water with special reference to key water quality parameters signifies immense importance for further reutilization so far the water productivity is concerned.

The flathead grey mullet, Mugil cephalus, is a mullet of the genus Mugil in the family Mugilidae, Kingdom: Animalia; Class: Actinopterygii; and Order: Mugiliformes; is a brackish water fish also can thrive well in fresh water and marine waters. Study on the food and feeding habits of Mugil cephalus was conducted between April, 2016 to March, 2017 at monthly intervals from Krishnapatnam and Mypadu coasts of Nellore District, Andhra Pradesh. Observation of feeding habits indicated flathead grey mullet as omnivorous feeder.

The perfect calm of an early spring dawn lies over headland and sea--hardly a ripple stirs the blue cheek of the bay. The softness of departing night lies upon the bosom of the Mediterranean like the dew upon the heart of a flower. A silent dawn. Veils of transparent greys and purples and mauves still conceal the distant horizon. Breathless calm rests upon the water and that awed hush which at times descends upon Nature herself when the finger of Destiny marks an eventful hour.

Tài liệu tham khảo giáo trình nhôm trong thiết kế xây dựng - Chương 3 Fabrication 3.1 PREPARATION OF MATERIAL 3.1.1 Storage Aluminium materials waiting to be fabricated are obviously best stored in the dry. But if they do get wet, at least they will not rust. One possible problem during storage is water staining, which appears as ugly blotches varying from white to dark grey [8]. This occurs when water is trapped between flat aluminium surfaces, and sometimes happens as a result of condensation when metal is brought in from the cold....
