Waste Management during COVID-19 Pandemic

Abstract: Solid waste management (SWM) is a general wellbeing administration whose significance is frequently downplayed. At the point when the strong waste administration challenge is exacerbated by a general wellbeing crisis, for example, the Covid-19 pandemic, its genuine centrality as a fundamental help turns out to be progressively evident. The episode and spread of the novel coronavirus (Covid-19) has prompted sensational changes of each segment of the Nigerian culture including SWM frameworks, where formal and casual on-screen characters exist together frequently in an uncomfortable relationship. Tragically, methodologies for comprehensive administration of strong squanders during and after the Covid-19 pandemic are inadequate in Nigeria, fuelling the further rejection of casual area in the waste administration and strategy process in Nigeria. This paper audits the condition of the Covid-19 pandemic in Nigeria, distinguishes strategy holes in strong waste administration and features the linkages between Covid-19 and SWM with the end goal of catalyzing comprehensive strong waste administration and supportability strategy in Nigeria. It is contended that recognizing the casual economy is the basic initial move towards confining a feasible SWM strategy in which essential partners are included. It is critical to perceive the job of waste laborers and administrations as a basic component, especially in this period. Squander assortment is critical to forestall a development of waste and to keep regions away from waste to empower other fundamental administrations to proceed. This is the reason squander workers have been allowed 'key specialist' status by the UK government, which means they will proceed to receive instructive and care arrangement for their kids during the current coronavirus crisis, so they will have the option to proceed with their basic administrations, and have been delegated Essential Services by numerous different nations. Furthermore, every region/neighborhood authority needs to create emergency courses of action that will ensure that basic waste administrations ought to be continuous regardless, just to ensure that no additional wellbeing dangers are included head of the pandemics. Emergency courses of action should include elective answers for staff, vehicles, irresistible waste, amassing of waste, washing, purification, and road cleaning administrations. The guideline behind the exhortation is that it isn't perilous for people to deal with their own recyclables in their own homes, since they can just taint themselves and their families, in the event that they are as of now wiped out or regardless uncovered. The wellspring of peril and crosscontamination is in the interface between the generator - viewed as an individual releasing or keeping their recyclables and waste into an open framework - and the handler - the expert who is accomplishing something with the recyclable materials or the remaining waste. Under this we incorporate the conventional waste and reusing frameworks yet in addition casual and semi-formal procedures extending from a network or general store reusing focus, a reclaim machine, to a low-pay network where numerous individuals are engaged with (casual) reusing or a swap meets or web based recycled exchange. A portion of these procedures are straightforwardly inside the control of legislative organizations or their private area operators, some can be by implication tended to by administrative foundations, and some are outside of any administrative or guideline office impact. Regardless, in view of the most recent logical data accessible, the microbe tainting is insignificant following 72 hours even on hard surfaces. The primary wellsprings of contamination according to waste and reusing will as a rule come at the interface between the generator and the handler. To be increasingly explicit, the second that an expert needs to come in physical contact with squander or recyclables from different people who may be contaminated. The direction should be evident that its essential objective is to address forms.

Treatment of domestic waste water using natural flocculants

Abstract: Wastewater generated from wastewater treatment plant contains odors some non pathogens, fecal Coliforms, fungus etc.,And chemicals such as phenols, nitrate, chloride etc. In addition to usual constituents such as urine and faeces. The present investigation was hence made in wastewater treatment plant situated in kallaraimedu of Kodaikanal. Presently the waste water is passing through an underground system to the wastewater plant. In this studyAnalyze the Physio-chemical parameters and biological parameters of septic water before and after treatment with horse and cow dung; and portable water. Isolate and identify the microbes present in horse and cow dung by using biochemical tests.

Application of bioremediation on solid waste management : A review

Abstract: Bioremediation is an alternative way to manage or to degrade the waste. It is eco friendly and much cost effective as compared to other traditional technique such as incineration. The main purpose of this paper is to pay more attention towards bioremediation. This paper outlines the different processes of bioremediation, their limitation and the process to remove different heavy metals, and other waste which is harmful to human beings. When metals are treated with microbes it get accumulated or attached on microbialmembrane.And after that it can be extract frommicrobes through cell fragmentation.

Partial Least Square Analyses Of Landscape And Surface Water Biota Associations In The Savannah River Basin

Abstract: Ecologists are often faced with problem of small sample size, missing values at some sites, correlated and large number of predictors, and high noise-to-signal relationships. This necessitates excluding important variables from the model when applying standard multiple or multivariate regression analyses. Partial least square(PLS) regression was developed particularly to deal with these problems. In this paper, we present the results of applying PLS to explore relationships among biotic indicators of surface water quality and landscape conditions where small sample size, missing data, and co linearity in variables existed. Available field sampling and remotely sensed data sets for the Savannah Basin are used. We were able to develop models and compare results for the whole basin and for each ecoregion(Blue ridge, piedmont, and coastal plain) in spite of the data constraints. The amount of variability in surface water biota explained by each model reflects the scale, spatial location and the composition of contributing landscape metrics. The landscape-biota model developed for the whole basin using PLS explains 43% and 80% of the variation in water biota and landscape data sets, respectively. Models developed for each of the three ecoregions indicates dominance of landscape variables which reflect the geophysical characteristics of that ecoregion.

Water hyacinth stems a potential natural adsorbent for the adsorption of acid green 20 dye

Abstract: The aimof this research was to investigate the potential of low- cost locally available stem water hyacinth (SWH) as an adsorbent for removal of acid green 20 (AG20) as an anionic dye fromaqueous solution. Equilibriumbehavior of SWH was investigated by performing batch adsorption experiments. The effect of initial dye concentration, pH, contact time and adsorbent dose on the adsorption process were evaluated. Adsorption isotherm models, Langmuir (four different forms), Freundlich and Temkin were used to simulate the equilibrium data at different experimental parameters (pH and adsorbent particle size). For Langmuir isotherm model, the four linear equations were discussed and used to obtain the isotherm parameters. Langmuir-II form was found to have the highest coefficient of determination (R2 = 0.999) compared with the other Langmuir linear equations.Also, it was found that SWH has a high adsorptive capacity towards MB dye (200 mg/g) as determined by Langmuir-II model. SWH show favorable adsorption ofAG2o dye with 0 < RL< 1. The intraparticle diffusion was also determined for the AG20-SWH system. The mechanism of the adsorption of AG20 dye onto SWH involved more than one process as indicating by the low value of Temkin constant bT (0.285 kJ/mol). Also, it was found that intraparticle diffusion was not the limiting step.
