  The treatment of water and wastewater using electrocoagulation (EC) is a newer method. It combines the benefits of electrochemistry, flotation, and coagulation. Electric current is used in an electrochemical procedure to eliminate dissolved, emulsified, or suspended contaminants from water. Because it is an environmentally benign choice that may create the least sludge, requires no chemical additions, and has the smallest footprint without impacting the water quality after treatment, electrochemical wastewater treatment technology has started to recover attention.     P rinciple of electrocoagulation   It's essential principle is based on how water molecules respond in a redox reaction to a strong electric field. In the process of oxidizing the anode material, coagulating agents are released, forming metal hydroxide complexes that neutralize particulate materials and produce agglomerates.     Working    A number of processes happen at once when...

  Wastewater  is any water that has been contaminated by animal and human use. Therefore , wastewater  may be a byproduct of native, industrial, and agricultural activities. The characteristics of  wastewater  very calculating on the source. Different Kinds of  Wastewater  include local  Wastewater  from households, municipal  Tannery Wastewater  from communities, and industrial  wastewater. Wastewater daf  can contain physical, chemical, and biological pollutants.   Households may produce  wastewater  from toilets flushes, kitchen, washing machines, bathtubs, and showers. Households that use dry toilets produce less  wastewater daf  than people who use flush toilets.   Leather wastewater  could also be conveyed during a sanitary sewer that conveys only sewage. Alternatively,  wastewater  is often transported throughout a joint sewer that transports both storm water runo...

  Many types of seafood products are available in INDIAN. in the market. From many different sources. IN INDIAN., Wild fish and shellfish are harvested by commercial fishermen in open seawater and seawater, and in freshwater lakes or rivers. Off-farm seafood products are grown on land in ponds (catfish), or renewable tanks (tilapia and hybrid bass), and in nearby coastal waters (salmon and shellfish). These same techniques are used to breed fish and mussel species in other parts of the world and are imported into the INDIAN marine food industry . Once seafood products are harvested, they are usually processed or packaged for distribution in stores and restaurants. Some of this seafood industry can be converted into second-hand processed heat and serving or ready-to-eat products such as salads in the seafood industry , infusions or other items. Retailers and food service vendors obtain raw and unused products from various domestic and foreign sources and distribute them in stores...

Waste water from seafood handling setups can be very high in BOD (bio-chemical oxygen demand), FOG (Fat, oil and grease) & nitrogen content.  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. The amount of pollution depends on the process.  Dissolved Air Flotation (DAF)  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 water treatment removes pollutantsby clearing the water by eradicating suspended soli...

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...
