B-Poly High Density treats concentrated sludge (indicatively [TSS] = 10-18%), and is characterized by mechanical homogenization pretreatment.
In its strong version, dedicated to dewatered sludge (indicatively [TSS] > 20%), it includes the turbodissolver, capable of liquefying the dewatered sludge again by appropriately adjusting its density by dosing water recirculated from the plant itself.
Controlling the density of the incoming sludge makes it possible to optimize the volumes of the carbonization (HTC) and solid-liquid separation stages with filter press, for overall energy and plant efficiency.
The biological processes involve an anaerobic acidogenic digestion, aimed at the production of volatile fatty acids (VFA), followed by the two integrated aerobic phases RANOX® and RAE®, deputed to mixed microbial culture (MMC) selection and PHA accumulation. The final green solvent extraction module allows obtaining the dried PHA.
B-Poly HD is the ideal solution for those who confer into a single treatment hub, concentrated or dewatered sludge that comes from smaller plants.
