What is the environmental significance of pH?
Environmental Significance of pH: A controlled value of pH is desired in water supplies, sewage treatment and chemical process plants. In water supply pH is important for coagulation, disinfection, water softening and corrosion control. In biological treatment of waste water, pH is an important parameter, since organisms involved in treatment plants are operative within a certain pH range. According to Bangladesh Environment Conservation Rules (1997), drinking water standard for pH is 6.5-8.5.
What are coagulants?
Anything that can change a fluid into a thickened mass. Blood coagulates or clots. Milk will curdle. In waste water treatment for example, Aluminium Sulphate is used in the process of cleansing sewage and industrial effluents
Are there high Ph levels in sewage?
Usually, sewage is acidic to a degree, but it depends on the specific effluents being conveyed by the sewer. The pH of sewage coming from industrial plants is regulated by the facility's waste water discharge permit, and the plant must control its waste pH in accordance with that permit. Effluents from other businesses and residences are regulated for pH by the plumbing codes, which mandate any acidic wastes be neutralized before discharging to the sewer. Regardless of these safe guards against chemical acids, sewage soils contains sulfates, which react with air and water in the sewer forming hydrogen sulfide gas, which is corrosive and attacks the piping materials. The pH of the outflow from sewage treatment facilities is highly regulated by the federal EPA and state agencies.
Why air along with microorganisms bubble into water in sewage treatment plant?
If microorganisms are used in the water treatment plant then it is necessary to provide oxygen to them and make the sludge degradation through them so air is bubbled for oxidation as well as for microorganisms.
Oxygen deficiency in a confined space can be caused by?
bacterial action, as from decomposition of sewage, chemical action, such as from rust, displacement by inert gases (e.g., nitrogen), and consumption, as from breathing or combustion from fuel-powered engines.
How do the microorganisms help in sewage treatment?
Sewage treatment plants use microorganisms to destroy the biological material in sewage.
How do the microorganisms help in sewage treatment plants?
Sewage treatment plants use microorganisms to destroy the biological material in sewage.

Which methods of dealing with sewage will ensure the future health of a local environment and the organisms that live within it?
sending the sewage to a biological water treatment plant
What is the most important role of aerobic bacteria in the treatment of waste water?
In the treatment of sewage, aerobic bacteria digest the biological materials in wastewater
What is the purpose of sewage disposal?
Here's the answer from Wikipedia. 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 a waste stream (or treated effluent) and a solid waste or sludge suitable for discharge or reuse back into the environment. This material is often inadvertently contaminated with many toxic organic and inorganic compounds. See this link for more details. http://en.wikipedia.org/wiki/Sewage_disposal
