Biological Waste Water Treatment In Nigeria

Biological Waste Water Treatment In Nigeria

Abstract

natural treatment of wastewater from Wupa Wastewater Treatment Plant, Abuja was delved . Wastewater samples were collected from the bay and effluent point( ahead and after the ultra violet radiation unit) of the treatment factory. The physicochemical parameters; temperature, pH, conductivity, total dissolved solids( TDS), total suspended solids( TSS) and dissolved oxygen( DO) were measured. The Biological Oxygen Demand( duck) and Chemical Oxygen Demand( COD) were attained from samples collected from the influent and effluent points using Standard styles specified by the American Public Health Association( APHA). The water samples were also analysed for the presence of bacterial organisms via Total Coliform Count( TCC), Total Bacteriological Count( TBC) and Faecal Count( FC). At the end of the analysis, the chance junking effectiveness of the ultra violet radiation for TCC, TBC and FC were calculated. Results showed that the mean junking effectiveness for TCC, TBC and FC were99.6,89.9 and98.9 independently; all within the admissible limit of World Health Organization and Federal Ministry of Environment. There was a reduction of81.5 in COD,98.9 in BOD which met the needed effluent norms. There was significant differences between the pH, TSS, DO, COD and BOD of the influent and effluent( P<0.05). These results showed that there’s an critical need for applicable way to be taken for proper operation and sanitation of the wastewater before discharging it to the sluice, to insure total conformity with the approved norms.

Preface

Background Of The Study

Water is a universal liquid that sustains being and all other lives. In fact that body is known to contain a lot of water and covers about 60 of the total land face. The first form of life was believed to have started from water millions of time ago and up till now no living effects can live without it. Water is one of the most common detergents and exists in gassy, liquid and solid state( Ababio 1990).

Hence, there are so numerous ways in which water is useful to mortal being. It can be used for drinking purpose, which is the most important use of water, it may be used for domestic purpose similar as bathing, washing, drawingetc. in manufacturing diligence and in Agriculture etc. thus, the important of water can not be overemphasized in the community( Encyclopedia Britain 1970).

Different type of natural water live on earth’s face which include; rain water, spring water, swash, lake water and ocean wateretc. rain water is considered as the purest from all natural water because it’s formal as a result of the condensation of water vapour in the atmosphere.

Spring water on the other hand emerges at the base of sloppy ground where the face elevation is below the water table, in an aquifer from where the water can escape( Fawole 1980).

still, water that contains many microbes may be considered good as longs as pathogen and inquiries chemicals are absent. nonetheless the quality of water is determined by the types and quality of microbes present in it. Some natural water could contain some microbes and still be good for use. Generally pollutants that can be set up in water include, microorganisms similar as bacterial, algae, protozoams, fungi,etc.

Some water are used in ménage, manufactories etc which are considered as waste water. Biologically these waste water can be treated and be used again. Biological waste water treatment is the common system used to treat water before it’s discharge to the communities.

natural waste water treatment system correspond of series of response vessels which are designed with the optimum mixing energy, retention time, and nutrient addition to give an optimum terrain for natural avidity performing in junking of nitrates heavy essence, ammonia, and biochemically oxidizable organic admixture as the biochemical oxygen demand( duck).

More so, Thomas E, Schultz( us sludge) explain that the use of bacteria and other microorganism to remove pollutants by assimilating them has long been a dependence of waste in the chemical process diligence( CPI) because they’re effective and extensively used. When considering natural waste water treatment for a particular operation. Thomas says, it’s important to understand the source of the waste water generated, typical waste water composition discharge demand events and practices withing a installation that can affect the quality and volume of the waste water and pretreatment ramification consideration of these factor will allow you to maximize the benefit of your factory earnings from effective natural treatment.

Aim And Objective

This main end if this study it to carry out exploration on how natural waste water will be treated in order to meet standard for reused by final consumer and with a view of acquiring and developing more understand of natural waste water treatment. This study embarks on the following

1. How natural waste water can be treated for reused.

2. To determined the applicable practical and system that can be used in treatment of natural waste water

3. To save large quantum of water

4. To enumerate different styles that are applicable in treating of water.

5. To use applicable outfit to get clean water for consumers.

Purpose Of Study

Generally, this study aims at all waste water set up in Nigeria and prefering remedies by which it can be treated biologically. Actually this will deliver home what’s really meant by waste water treatment.

The study is also embark water that contains a many microbes which may be pernicious chemicals are absent. It also expanciate how desolate water is being generatedi.e water from ménage, manufactories e t c which are considered as waste water and proffering a system in which can be treated. The end of these study is to treat waste water which is natural waste water treatment

Compass Of Study

With full details gotten from colorful test, it shows that water is demanded to be treated before used and these treatment is traceable to be combination of factors which are fund, tone interest, seasons, conditions etc

therefore, this study covers a precise story of perfecting the rate at which water is treated to full scrap before operation.
