BIOLOGICAL CHARACTERISTICS OF INDUSTRIAL WASTEWATER

The major biological processes used for wastewater treatment are five major groups. Sewage consists of vast quantities of bacteria most of which are harmless to man.

Sewage Or Waste Water Characteristics Wastewater Consists Of

The characteristics of the domestic sewage and its treatment method.

. Wastewater that is discharged to the environment without suitable treatment can cause water pollution. 2 to protect shellfish finfish and wildlife. Temperature affects chemical reaction and biological activities.

Aerobic processes anoxic process anaerobic process combined aerobic anoxic and anaerobicaerobic processes. However pathogenic disease-causing organisms such as typhoid dysentery and other intestinal disorders may be present in wastewater. V Solid contents Total solids.

Various Sources of the Domestic Sewage 67. The most important physical characteristics of wastewater are its temperature and its solids concentration. Microaerobic conditions maintained in the SBR allow for biomass accumulation in large amounts leading to 85 lactose reduction via rapid fermentation and subsequent protein coagulation by 90.

The Biological Wastewater Treatment series is based on the book Biological Wastewater Treatment in Warm Climate Regions and on a highly acclaimed set of best selling textbooks. Biological Characteristics The sewage contains many microorganisms like bacteria algae fungi protozoa etc. Biological treatment of wastewater from vegetable oil production is an important step to protect the environment from pollution.

The wastewater produced by a tannery including preparation of the hides has a fairly acid pH and high chloride content up to 5 g ClL. In a bench-scale SBR raw industrial dairy wastewater was treated with Lactobacillus casei TISTR 1500. Biological Characteristics of Wastewater.

Characteristics of industrial waste water vary greatly from industry to industry and. The characteristics of wastewater vary depending on the source. Bacteria being the most predominant.

The wastewater comes from two sources. Following are the different type of wastewater which are admitted into the sewers. Industrial wastewater especially from chemical and pharmaceutical production often contains substances that need to be treated before being discharged into a biological treatment plant and subsequent water bodies.

75 Wastewater Collection and Characteristics. Industrial wastewater characteristics vary not only between the industries that generate them but also within each industry. Color - Fresh sewage is normally brown and yellowish in color but over time becomes black in color.

Concentrations of biological oxygen demand BOD and suspended solid 3Compared to other industrial sectors the food industry uses a much greater amount of water for each ton of product 4. Colour is a qualitative characteristic that can be 3 to preserve or restore. Biological characteristics of sewage.

Nitrogen content free ammonia organic nitrogen albuminiod nitrogen nitrites nitrates Fat grease and oil content Sulphides sulphates snd H2S gas Dissolved oxygen DO Chemical oxygen demand COD Biological oxygen demand BOD. INDUSTRIAL WASTEWATER CHARACTERISTICS Rein Munter The purposes of pollution control endeavours should known as volatile solids the latter as fixed solids. Broadly categorised as physical chemical and biological characteristics.

Most of the bacteria found in the sewage are harmless non-pathogenic bacteria. The aerobic biological processes are further subdivided depending on whether treatment is accomplished in suspended growth systems attached growth systems or. PH value Fresh sewage has pH between 73 to 75.

Wastewater can contain physical chemical and biological pollutants. The principal groups of microorganisms found in wastewater. Odor Wastewater that includes sewage typically develops a strong odor.

Carbohydrates fats proteins toxins Inorganic. Ad Aster Bio offers both genetic testing advanced bioaugmentation products. The Engineer should know-1.

Udo Birkenbeul in Industrial Wastewater Treatment Recycling and Reuse 2014. Following are important physical characteristics of wastewater. This international version is comprised by six textbooks giving a state-of-the-art presentation of the science and technology of biological wastewater treatment.

Wastewater is used water from any combination of domestic industrial commercial or agricultural activities. Temperature and solids content in wastewater are very important factors for wastewater treatment processes. The three biological organisms present in wastewater are bacteria viruses and parasites.

Biological Characteristics-The environmental engineer must have considerable knowledge of the biological of waste water because it is a very important characteristics factor in wastewater treatment. Fungi like Fusarium and Sporotricum are found in sewage which. On the one hand water is a waste product of oil production and on the other hand a large amount of wastewater is produced.

CHARACTERISTICS OF INDUSTRIAL WASTEWATER Industrial process generate a wide variety of wastewater pollutant. Characteristics of Wastewater from the PulpPaper Industry and its Biological Treatment Technologies January 2009 Journal of the Korean Institute of Resources Recycling 182. Alkalinity N P S pH metals salts Gaseous.

H 2 S CH 4 O 2. The characteristics and level of pollutants very significantly from industry to industry Table 11 Example of industrial wastewater concentration for BOD5 and suspended solids Davis and Cornwell2008 Industry BOD5mgL Suspended Solid mgL. A company from Croatia has specialised in the production of sunflower seed oil.

Cultures for starting and restoring biological units including nitrifiers AOBNOB. As a consequence 70 of COD degradation can. Foul and unpleasant odors may then develop as a result of septic sewage.

Which gives an approximate amount of settleable solids. Wastewater Characteristics Physical Chemical Biological solids temperature color turbidity salinity odor Organic. Be 1 to protect the assimilative capacity of surface Usually volatile solids are organic.

Two types of bacteria are found in sewage. Plants algae grass etc microorganisms bacteria viruses. Important chemical characteristics of sewage are.

Biochemical Oxygen Demand BOD Oxygen required for nitrification. It contains a high concentration of COD about 1500 2500 mgL a high amount of settable substances 10. Generally this can be done close to the site of production itself in.

Non-pathogenic intestinal bacteria are normal flora of.
