  Waste water from  Sea Food Waste Water Industry  handling setups can be very high in BOD (bio-chemical oxygen demand), FOG (Fat, oil and grease) &  dewatering .  Dissolved air flotation and flocculation  is the key component of the sea food  wastewater treatment plant . Sea food processing plants yield  waste water  holding a large amount of pollutants which are soluble, colloidal and in particulate forms.  dewatering sludge  depends on the process.  Dissolved Air Flotation  is extremely prevalent  waste water treatment process  usedby a large number of industries such as petrochemical and chemical plants, papermills, refineries, hospitals, etc. This  DAF technique  is used in order to remove pollutants loads in the waste water before discharging it in the mainstreams. These pollutants can be termed as BOD, COD, fat oils, grease, chemicals, pharmaceuticals, suspended solids, etc.  DAF  w...

Wastewater treatment, also known as sewage treatment, the cleaning of impurities from sewage or wastewater, before it reaches to natural bodies of water like oceans rivers, estuaries and lakes. Since it is hard to find pure water in nature (i.e., outside chemical laboratories), any distinction between clean water and polluted water depends on the sort and concentration of impurities found in the water also as on its intended use. In broad terms, water is claimed to be polluted when it contains enough impurities to form it unfit for a specific use like swimming, fishing or drinking. Although water quality is suffering from natural conditions, the word pollution usually implies act because the source of contamination. Wastewater treatment plants are introduced to purify all the wastewater. Water pollution, is caused primarily by the drainage of contaminated wastewater into groundwater or surface water, and wastewater treatment may be a major element of pollution control. There are thre...

The use of physical/chemical methods and also the application of contact-assisted activated sludge process are investigated. These tests were dole out in a very 310-m3/d plant. The analysis of plant performance was supported the standard of treated water created and also the value of the plant relative to every configuration.  The results show that a 2 stage dissolved air flotation units combined with contact-assisted activated sludge method would alter the plant to satisfy the discharge standards projected by the Kuwait Environmental Protection Authority.   Fat/oil/grease is reduced by concerning 84 %; suspended solids area unit reduced by concerning seventy two across the first stage DAF. The contact-assisted activated sludge reduces the ultimate effluent COD to but 250 mg/L. Finally, substantial amounts of total suspended solids area unit removed throughout the ordinal stage DAF method.  The world analysis for a well-designed and properly operated co...
