Biological Oxygen Demand ( Bod ) - 1720 Words

Other Parameters Biological Oxygen Demand (BOD) is also monitored to quantify the amount of oxygen needed to break down organic material in a water sample. BOD was generally higher and more variable at different locations around Abu Dhabi City and in Confined Areas, although mean BOD at all locations was generally lower from 2013–2015 than in previous years for which data are available. Total Suspended Solids (TSS) are solids in water that can be trapped by a filter and may include a wide variety of material, such as silt, decaying plant matter, industrial wastes, and sewage. In general, TSS has been higher in the past 5 years in Confined Areas than at the other stations. TSS has declined since 2011 at all locations except in MPAs, where the annual mean TSS was highest in 2013. Mean TSS in 2015 was highest in May in Confined Areas. Organic pollutants are chemical compounds that contain carbon and have a negative effect on one or more components of the environment. From 2011–2015, EAD monitored marine waters for two organic pollutants: total petroleum hydrocarbons (TPHs) and polychlorinated biphenyls (PCBs). TPHs is a term used to describe a mixture of several hundreds of chemical compounds that are derived from crude oil. Measurable background concentrations of TPH can be a result of excess oil contamination or in some cases the result of a natural petroleum seep. High levels of some petroleum hydrocarbons can cause adverse health effects, including benzene, which is aShow MoreRelatedAssessment Of Bod, Cod As Organic Pollution Indicator Levels Of Varhala Lake Essay1442 Words   |  6 PagesASSESSMENT OF BOD, COD AS ORGANIC POLLUTION INDICATOR LEVELS OF VARHALA LAKE ABSTRACT Lakes are of great importance both from the natural and economic point of view. Lake water is a source of drinking and domestic water supply for people living in and around the area. The present study was conducted to assess the organic pollution indicators like BOD, COD and DO. The sampling of water was based on human and aquatic activities around the lake. Water from five sampling stations of Varhala Lake wasRead MoreImportance Of Water Quality Analysis1596 Words   |  7 PagesAs a follow-up to the request for proposals for obsolete equipment replacement funds, from the Financial Services Division, I have assessed the current Biological Oxygen Demand (BOD) testing equipment used for water quality analysis by the Water Quality Research Laboratory Division.

Hence, it includes refractory fractions of organic matter as well as reduced inorganic constituents present in the wastewater. The COD measurement offers quick estimate of carbonaceous material compared to conventional BOD measurement. Additionally, high COD reflects inert reducedRead MoreThe Two Arrangements of Water Quality Parameters753 Words   |  3 Pageshardness, alkalinity, salinity, and temperature are not affected significantly by activities of microorganisms. [30] Ammonia, nitrate, nitrite, total nitrogen, pH, phosphorous, dissolved oxygen, conductivity, total dissolved solids, chemical oxygen demand, and oxygen reduction potential which are affected by biological activity are considered as non-conservative.

The influent BOD5 is inconsistent and the average being 855 mg/l at the inlet of the aeration tank. The BOD5 to COD ratio at the inlet of the aeration tank is varying from 0.57 to 0.78, which suggests that the biological treatment provided in the existing treatment plant is justifiable. The overall efficiency is found to be 56.41% only. Hence it may be concluded that the CEPT performance is not in accordance with desired or designed efficiency.

Analysis will include Biological Oxygen Demand (BOD) along with total, volatile, and fixed suspended solids. Methods for analysis will include the Winkler Test for BOD and a Hatch test for the suspend solids. The report finds BOD levels meet the National Pollutant Discharge Elimination System (NPDES) permit renewal standards. Results for suspended solids shows an oppositeRead MoreA Report On The Buffalo Creek Basin1283 Words   |  6 Pagesselected for statistical analysis. The Biological Oxygen Demand (BOD), is the amount of oxygen consumed by bacteria in the decomposition of organic material. It also includes the oxygen required for the oxidation of various chemical in the water, such as sulfides, ferrous iron and ammonia. While a dissolved oxygen test tells you how much oxygen is available, a BOD test tells you how much oxygen is being consumed. BOD is determined by measuring the dissolved oxygen level in a freshly collected sampleRead MoreSewage Treatment Of Sewage Water Treatment Essay3390 Words   |  14 Pageswater and so on entered as an influent there and get separated to such reach out before it get released in a regular course with the goal that it ought not dirty a water body where it going to release, here fundamentally 5 parameters are checked COD, BOD.
