Qualitative optimization of process sludge using “EBF Reactor”
Biological treatment is the central element of any civil and industrial wastewater treatment plant and its operation inevitably affects every other aspect of the plant.
Being a biological process based on a biomass that forms spontaneously in the units, it is often difficult to achieve optimal conditions with the normal means available to the operator (sludge recirculation and aerated mixture, sludge extraction).
Through this technique the bacterial strains most favorable to purification and sedimentation of the sludge are selected to the detriment of the filamentous forms, up to the progressive disappearance of the latter.
Starting from the principle that purification efficiency cannot exist without the production of sludge, the optimization consists in making this burden lighter, which represents a significant percentage of management costs.
Disposing of incorrectly treated sludge produces very high waste and operational difficulties.
In this field the company has developed a production system consisting of a mixture of poly electrolyte combined with the specific equipment denominated “Feederpoly”.
The company develops using its own design, the complete sludge drying and dehydration systems in partnership with international producers.
The Compact MBBR is a highly effective biological treatment process based on a combination of conventional activated sludge process and biofilm media. The MBBR process utilizes floating High Capacity Carrier media within the aeration and anoxic tanks.
The microorganisms consume organic material. The carriers, in highly porous plastic material, are movable inside the tank.
The biological mass adheres and grows on the surface of the carrier, especially inside.
The carriers have a high surface area that reduces the footprint of the tanks required to treat the wastewater.
The treatment process can be aerobic and/or anaerobic and operates at high volume loads.
Solar Drying
Mechanical dewatering of sludge is efficient up to a dry substance of 20 to 30 %, leaving in one metric ton of filtercake still 700 to 800 kg of water.
This residual water can only be removed with high amounts of thermal energy used to evaporate this water.
At solar drying, the residual water is evaporated utilizing solar energy only.
The radiation is warming up the filtercake in the drying halls and leads to the evaporation of water.
The evaporation rate is significantly determined by the location of the system and is basically higher as you get closer to the equator.
