DOTS is just about making sure that the patient is really taking in his TB regimens – like literally swallowing the medicines on schedule. It‚ however‚ is not just as simple as that. DOTS or Direct Observed Treatment‚ Short-Course is the WHO-recommended strategy for diagnosis‚ treatment and management of TB. Since TB is curable‚ the WHO believes that the best way to cure TB is through DOTS. It is a health strategy made up of five important components: Political Commitment for TB Control; Facilities

Activated Sludge Process will encompass * Design of aeration basins. Relevant design parameters are * BOD load from the upstream process * Mixed Liquor Suspended Solids Concentration (MLSS – mg/l) – typically 2‚000 to 4‚000 * Sludge Age 5 to 25 days * Sludge settleabiltiy (SVI ml/g) typically 100-120 * Process Oxygen Demand (POD) * Generally fine bubble diffusers used in modern plant design – actual oxygen transfer efficiency dependent

as an alternative water source. This results in an independent water source which through treatment can provide consistent quality water. Canal water is sent through a water treatment process with unused water sent back to the source with little environmental impact. The scope of this project is to assess the environmental impact of an onsite water treatment facility. Chapter 2. Overview of Water treatment Process design 2.1 Design process The feed water will pass through 20 micron media filter

The Ashley Treatment Ashley is a nine-year-old girl with the mental age of a three-month-old. Her condition means she will never walk‚ talk or even roll over. She is totally helpless without the devotion and care of her parents. In 2004 her parents decided to medically intervene with puberty. Along with hormone doses to limit her growth‚ Ashley ’s parents also decided on surgery to block breast growth and had her uterus and appendix removed. I am going to give the arguments for and against this

Unfair treatment of the Native Americans- the Cherokee Nation Throughout the 19th century Native Americans were treated far less then respectful by the United States’ government. This was the time when the United States wanted to expand and grow rapidly as a land‚ and to achieve this goal‚ the Native Americans were “pushed” westward. It was a memorable and tricky time in the Natives’ history. The US government made many treatments with the Native Americans‚ making big changes on the Indian nation

SEWAGE TREATMENT Sewage is a mixture of domestic and industrial wastes. It is more than 99% water‚ but the remainder contains some ions‚ suspended solids and harmful bacteria that must be removed before the water is released into the sea. The treatment of wastewater is divided into three phases: pretreatment‚ primary treatment and secondary treatment. Pretreatment Large solids (i.e. those with a diameter of more than 2cm) and grit (heavy solids) are removed by screening. These are disposed of in

Sewage treatment plan Sewage treatment is the process of removing contaminants from waste water and household sewage‚ both run off (effluents)‚ domestic‚ commercial and institutional. It includes physical‚ chemical‚ and biological processes to remove physical‚ chemical and biological contaminants. Its objective is to produce an environmentally safe fluid waste stream (or treated effluent) and a solid waste (or treated sludge) suitable for disposal or reuse (usually as farm fertilizer). Origins

Sewage treatment The objective of sewage treatment is to produce a disposable effluent without causing harm to the surrounding environment and prevent pollution.[1] Sewage treatment‚ or domestic wastewater treatment‚ is the process of removing contaminants from wastewater and household sewage‚ both runoff (effluents) and domestic. It includes physical‚ chemical‚ and biological processes to remove physical‚ chemical and biological contaminants. Its objective is to produce an environmentally-safe

All surface water and some groundwaters require treatment prior to consumption to ensure that they do not represent a health risk to the user. Health risks to consumers from poor quality water can be due to microbiological‚ chemical‚ physical or radioactive contamination. However‚ microbiological contamination is generally the most important to human health as this leads to infectious diseases which affect all populations groups‚ many of which may cause epidemics and can be fatal. Chemical contamination

systems in many countries and provinces. This basically ignored the downstream effect of improved water supply‚ that of increased discharges into rivers or aquifers. Two reasons appear to be the major cause for that: firstly‚ wastewater collection and treatment is costly and their benefit often hard to show; and secondly‚ even if low-cost solutions are being implemented many projects fail to deliver the expected outcome. Without pretending to reflect the complexity of sanitation projects three principal
