 Industrial waste waters commonly comprise organic and inorganic matter in fluctuating degrees of concentration. They may comprise of toxic and other harmful supplies as well as elements that are non-biodegradable or that can decrease the effectiveness of many waste water treatment procedures. Thus, treatment of industrial wastewaters usually is a very challenging task - far more complex than municipal wastewater treatment. DAF is used extensively in the following industries-Meat, poultry, fish processing, Pulp and paper, Dairy industry, Food and beverage and Petrochemicals.

Eliminating large, suspended and floating solids along with oil and grease is the main focus of the first stage of wastewater treatment. Elimination of oily contaminations through the help of DAF system installed in chemical industry wastewater treatment is an effective flotation technique for water clarification. The word states to the technique of creating flotation by dissolving air in the water under pressure and then discharging the pressure. When the pressure is discharged the solution converts super-saturated with air as loads of tiny bubbles form. These bubbles fasten to the particles in the waste water affecting the density of the particle to become lighter than that of water. The particles then quickly float to the surface for accumulation and elimination; setting behind the clarified water. A common design uses a discrete pressure vessel for compressed air supply.

  #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
