Use and specifications
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 aerobic bacteria that transform the biodegradable compounds into CO2, organic nitrogen into ammonia and ammonia into nitrates.
2. SEDIMENTATION AREA: stilling area in which the residual sludge sediments and returns once again to the oxygenation 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).
TECHNICAL CHARACTERISTICS
Activated sludge plants are secondary treatment systems that make use of the action of the bacterial colonies that, remaining in suspension in the sewage, consume the biodegradable 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 degradation of the organic load. Very high concentrations of aerobic type bacteria are developed inside activated sludge plants, sufficient, that is, to absorb the dissolved oxygen in the water in order to consume the biodegradable material. To guarantee the concentration of oxygen necessary for the development of the biological reaction, an aeration system is adopted consisting of submerged diffusers which, from the bottom of the tank, disperse a flow of fine air bubbles. This also guarantees sufficient mixing to keep the high concentrations of solids present in the tank in suspension.
USE: secondary treatment of domestic sewage.
