Water treatment * Water treatment - describes those industrial-scale processes used to make water more acceptable for a desired end-use. These can include use for drinking water‚ industry‚ medical and many other uses. Such processes may be contrasted with small-scale water sterilization practiced by campers and other people in wilderness areas. The goal of all water treatment process is to remove existing contaminants in the water‚ or reduce the concentration of such contaminants so the water

amounts of water consumed in the brewing process as well as washing and sterilizing procedures. It is estimated that between 4 and 7 L of water is required to produce 1 L of beer. Beer is the fifth more popular drink in the world so to meet this demand; large quantities of water are required. Water chemistry has an effect on the brewing efficiency as well as the taste‚ so water from water authorities must be treated in order to produce water which is acceptable for brewing. Demand for water has become

The unwanted catch (bycatch) is thrown back into the water but it does not replace what was harmed. Finally‚ the silt that the net stirs up gets suspended in the water column and blocks out the sun. Primary production and photosynthesis cannot occur without that sunlight so the ecosystem cannot recover. Long line fishing is another method of fishing that involves

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

How water is purified in water treatment plants Pre-treatment 1. Pumping and containment – The majority of water must be pumped from its source or directed into pipes or holding tanks. To avoid adding contaminants to the water‚ this physical infrastructure must be made from appropriate materials and constructed so that accidental contamination does not occur. 2. Screening (see also screen filter) – The first step in purifying surface water is to remove large debris such as sticks‚ leaves

Water Recycling Recycled water- is former wastewater that is treated to remove solids and certain impurities‚ and used in sustainable landscaping irrigation or to recharge groundwater aquifers. The purpose of these processes is sustainability and water conservation‚ rather than discharging the treated water to surface waters such as rivers and oceans. Undoubtedly‚ recycling or re-using water can offer very significant economies. One of the greatest obstacles is the fact that much of the wastewater

Water supply and sanitation in Bangladesh is characterized by a number of achievements and challenges. The share of the population with access to an improved water source was estimated at 98% in 2004‚[1] a very high level for a low-income country. This has been achieved to a large extent through the construction of handpumps with the support of external donors. However‚ in 1993 it was discovered that groundwater‚ the source of drinking water for 97% of the rural population and a significant share

Wastewater treatment plants: * Remove solids‚ everything from rags and plastics to sand and smaller particles found in wastewater; * Reduce organic matter and pollutants--naturally occurring helpful bacteria and other microorganisms consume organic matter in wastewater and are then separated from the water; and‚ * Restore oxygen--the treatment process ensures that the water put back

“Primary Treatment of wastewater consists of the removal of insoluble matter such as grit‚ grease‚ and scum from water.” (Manahan‚ 2010) The first step of this treatment involves screening which prevents large solids from getting into the treatment process. This is followed by an oil and grease trap in which oil skimmers are used to separate oil and grease from the effluent. The separated oil and grease are then given to recyclers. From this the water is transferred to the collection tank and from
