The industrial waste water from agricultural and sideline food processing industry contain high concentration of organics and suspended substance. Food wastewater is composited of natural organic matters (such as protein, fat, sugar, starch), so they are of low toxicity and high BOD/COD value (up to ).Cited by: Pollution of the Ocean by Sewage, Nutrients, and Chemicals Coastal waters receive a variety of land-based water pollutants, ranging from petroleum wastes to pesticides to excess sediments. Marine waters also receive wastes directly from offshore activities, such as ocean-based dumping (e.g., from ships and offshore oil and gas operations).

BOD reduction is used as a gauge of the effectiveness of wastewater treatment plants. BOD of wastewater effluents is used to indicate the short term impact on the oxygen levels of the receiving water. BOD analysis is similar in function to chemical oxygen demand (COD) analysis, in that both measure the amount of organic compounds in water. Chemistry and Water: Challenges and Solutions in a Changing World summarizes the outcomes of the sixth CS3 which was held in September , in Leipzig, Germany focusing on water, health and the environment, detection of pollutants, recovery of resources, and water treatment. Top water chem-ists and engineers from China, Germany, Japan, the.

Some authorities advise consumers to avoid regular consumption of hot dogs, bacon, and lunchmeats because they contain a suspected carcinogenic food additive which is intended to deter spoilage and to make the meat. Actual situation of wastewater from food industry and a case study of their treatment January Journal of environmental protection and ecology 20(1) High levels of pollutants mainly organic matter in river water cause an increase in biological oxygen demand (Kulkarni ), chemical oxygen demand, total dissolved solids, total suspended solids and fecal coli form.

They make water unsuitable for drinking, irrigation or any other use (Hari ).File Size: KB. Water auditing is a method of quantifying water flows and quality in simple or complex systems, with a view to reducing water usage and often saving money on otherwise unnecessary water use. There is an increasing awareness around the globe of the centrality of water to our lives.

Chemical characteristics of sewage and their testing 1. CHARACTERISTICS OF SEWAGE AND THEIR TESTING SUBMITTED BY: NAINA GUPTA 2. The Chemical Characteristics of sewage helps in indicating: the stage of sewage decomposition, its strength, and extent and type of treatment required for making it safe.

Examination of water for chemical substances. Filter: Published standards Standards under development transformation products and other organic substances in water and treated waste water — Method using high performance liquid chromatography and mass spectrometric detection (HPLC-MS/MS or -HRMS) after direct injection.

Significance of findings: This study suggests that mixtures of pharmaceuticals, hormones, and other wastewater contaminants can occur at low concentrations in streams that are susceptible to various wastewater sources. It provides methodology and guidance for future monitoring and assessment of these types of environmental contaminants, and establishes the needed.
