Biological sewage treatment plant NIFA1000

activated sludgecompact

ACTIVATED SLUDGE PLANTS LOW-LOAD 1.OXYGENATION AREA: area in which the effluent is mixed and oxygenated. thanks to micro-bubble air diffuser plates, powered by an external blower/compressor. This develops aérobic bacteria that transform the biodégradable compounds into C02. organic nitrogen into ammonia and ammonia into nitrates. 2.SEDIMENTATION AREA: stilling area in which the residual sludge sédiments and returns once again to the oxygénation section. 3.FINAL DISINFECTION: housing. on the outlet pipe, into which a slow release chlorine tablet is inserted. In this way the effluent is disinfected before being discharged. 4.BLOWER (included). 5.DIFFUSER PLATE (included). SPECIFICATIONSTECHNICAL CHARACTERISTICS: Activated sludge plants are secondary treatment Systems that make use of the action of the bacterial colonies that. remaining in suspension in the effluent, consume the biodégradable organic material, using it as a nutrient to obtain the necessary energy and the material required for the synthesis of new cells. In this manner. increasingly stable compounds are formed leading to the total dégradation of the organic load. Very high concentrations of aérobic type bacteria are developed inside activated sludge plants, sufficient. that is. to absorb the dissolved oxygen in the water in order to consume the biodégradable material. To guarantee the concentration of oxygen necessary for the development of the biological reaction, an aération System is adopted consisting of submerged diffusers ep the high concentrations of solids présent in the tank in suspension. USE: secondary treatment of domestic sewage.
