Sea Food Waste Water Treatment

-
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 solids.

  #SludgeDewatering   #ComboUnit   #Thickener +BeltFilterPress Krofta Engineering Ltd, India  Introduces newer version, enhanced capacity “Triple Wire Belt Filter Press” which is a COMBO UNIT (Thickener + Dewatering) Triple-Wire Belt Filter Press. This combo unit can work even at 0.8% sludge consistency without using separate thickener for dewatering Primary & biological secondary sludge generated at Industries & municipal plants. > In built flocculator comes as a standard supply with this new design > Low power consumption compared to other systems. The purpose of sludge dewatering is for waste minimization & to achieve overall cost efficiency for disposal. This machines has several combined processes added into one unit and it involves different applications such as chemical conditioning, gravity drainage and mechanical shearing and compression effect to remove water and dry up the sludge. Today, belt filter presses are widely used and it has become a standard for g

Tannery Wastewater Treatment

  Tannery wastewaters  are highly complex and its treatment is administered by physical or chemical or biological or a combination of those methods. From the review, it is often concluded that physical/chemical processes combined with the organic process is the better option for the treatment of tannery wastewater. The tanning industry is one of the oldest industries on the planet and therefore the problem of treatment and disposal of those wastes is perhaps as old because of the industry itself.  Tanneries wastewater  effluent is treated in many various ways. There are situations during which a private tannery applies all the below-described  wastewater treatment  steps on site. In other situations a private tannery may apply (on-site) only pre-treatment or a neighborhood pre-treatment or no treatment in the least, sending the effluent to a centralized effluent treatment plant. Nevertheless, treatment is important thanks to the wide selection of toxic effects on the environment caused
