The spectrophotometer is in use to measure the intensity of red color produced when nitrate reacts with the acid, sulfanilic and N- naphthyl ethylenediamine. The lack of calibration of the equipment causes errors in results. The equipment may record a reading higher or below the one expected. Errors result from measurements done by using flasks and pipettes. When experimenters fail to monitor the readings properly, the final value of concentration will be affected.   For example, observers of volumetric readings should look at the lower meniscus to prevent these errors. Such errors will affect dilution and dissolving of solids in solutions (Woody 12).  The possible causes of errors may result from wrong or inaccurate readings made in the spectrophotometer.

Upgrading wastewater treatment facilities
...and process. The sludge that results from the CEPT technique is about 10 to 15% higher than that resulting from removal of suspended solids. Last, CEPT is an appropriate and effective first stage treatment process, and biological treatment may follow based on justification and affordability. Conclusion The main water-related environmental concern eminent in urban areas of most developing countries is public health. Receiving water and drinking water sources are often contaminated inadequately treated wastewater effluents. Despite the presence of conventional primary treatment, disinfection of effluent is not effective (Shi, 2011:27). The main objective of upgrades to...

Wastewater Management
...?Wastewater Management Secondary treatment involves the unique biological systems that are designed to remove suspended and dissolved solids through conversions that are biological to transform them into settleable form. Tertiary treatment is basically the polishing process that normally filters the treated water through passage of fine sand to remove the finely suspended solids. Despite the effectiveness of the two treatment methods, there are some key challenges that are face the treatment methods. For example, many of the water treatment methods and collection facilities are now worn out hence require further improvement, replacement or repair in efforts to maintain their standards (Bartram & Lentron,...

Nitrogen Recovery in WasteWater Treatment
...?Nitrogen Recovery in WasteWater Treatment Nitrogen is an essential nutrient for plants and animals. Approximately 80 percent of the Earth’s atmosphere is composed of nitrogen, and it is a key element of proteins and cells. Nitrogen is a constituent in human sewage. The major contributors of nitrogen to wastewater are human activities such as food preparation, showering, and waste excretion. The most common forms of nitrogen in wastewater are: Ammonia (NH3), Ammonium ion (NH4+), Nitrite (NO2?), Nitrate (NO3?), Organic nitrogen. Nitrogen in domestic wastewater consists of approximately 60 to 70 percent ammonia?nitrogen and 30 to 40 percent...

Chlorine is usually determined in these samples by ion chromatography and spectrophotometry after its isolation in form of HCl. Advances in the technique of XRF spectrometry and development of TXRF technique for analysis of trace elements has led to its use in determination of levels of Cl in (U, Pu)C fuel as described by Misra and...

...?WATER QUALITY Water Quality and Wastewater Management Word Count: 500 I. Introduction It is standard practice—especially in the Western part of the United States—to inject treated wastewater into the ground, where it is added to the groundwater table. Based on the fact of managing a large water district with a local city council member insisting upon secondary treated wastewater instead of tertiary treated wastewater, the following research is going to investigate the difference between the two types of wastewater. Here, what is going to be accomplished is: 1) a comparison-contrast of secondary water...

...cause serious damage to the ecosystem. Besides, it can also affect the people who use this water for drinking or any other household purposes. It is therefore essential that the industrial effluents are treated to high standards before they are released. Industrial effluents can contain a mixture of contaminants which make them unfit for further use. The most common pollutants and possible methods for their removal are presented in the following table. (Source: Nesaratnam, 81-100) The different types of contamination of wastewater require a variety of strategies to remove the contamination. There are different processes that can be used to clean up...

Wastewater Treatment Methods
...RUNNING HEAD: WASTEWATER TREATMENT METHODS Wastewater Treatment Methods Wastewater Treatment Methods The initial costs of setting up water recycling treatment plant s are very expensive. The equipment found in the treatment plant is determined by the purpose the recycled water is intended to serve. Non-potable water, this is water not fit for human consumption requires only equipment needed for the primary and secondary man. For water fit for drinking, additional equipment for the tertiary process need to be set up. This means more costs must be incurred. Despite the initial great costs, the benefits of the reclaimed water that has undergone the final stage are more and...

...on the globe, it is everyone’s responsibility to use, establish and put into practice inventive ways of managing wastes and resources (World Resources Institute, 1996). Wastewater refers to water that has been hugely affected in condition by the influence of anthropogenic. These constitute liquid waste produced by industry, domestic properties, agriculture and/or commercial properties and can take in an extensive variety of probable concentrations and contaminants. Moreover, municipal wastewater is frequently treated in an effluent sewer, sanitary sewer, septic tank or combined sewer. It is likely to establish an association between contaminants of waste in a...

Default Determination
...analyzing everything that it entails, as well as the remedy of default termination in the context of federal procurement in reference to the nature of the course. In termination for default, the government always wants to have the upper hand on the contract hence always trying to make sure that the contract is always to their advantage. So in that case, in order for the government to prevail in the defense of a termination by default, the government must establish that the termination of the contract by default prior to the contract completion date was effective, proper and correct. Since this default termination is such a drastic action, the federal procurement must show how its determination was well grounded and had...

Calculate the total moles of EDTA added to the sample solution. Calculate the average titre of EDTA: Average titre = 7.8 0 + 7.75 + 7.70 = 7.75 x 10-3l Therefore moles of EDTA = concentration (moll-1) x volume = 0.05x 7.75 x 10-3= 3.875 x 10-4 mol 2. Calculate the moles of the magnesium chloride...
