Description

BIOGRADEX Technology is patented all over the world. Its principle is based on vacuum degassing of mixed liquor between bioreactors and secondary clarifiers. Process changes settling characteristic of activated sludge and allows using higher design parameters of wastewater treatment system and reducing size of the plant.
BIOGRADEX Technology was well proven during many years of research and development prior to obtaining the patent. It allowed developing fully proven and undisputable plant design parameters. The theory and research are proven by treatment results from over 37 WWTP’s in operation.
BIOGRADEX Technology forms a higher world class level of wastewater treatment technology.
Benefits of BIOGRADEX Technology:

• Mixed liquor TSS concentration in bioreactors: 6,000 ~ 9,000 mg/L.
• 1,5 ~ 3 times reduced bioreactor volume in comparison to conventional technologies (as per ATV-DVWK-A131 guidelines).
• Increase of secondary clarifier mass flux (solids surface loading) for average flow (Q ave), excluding Return Activated Sludge (RAS) flow to 85~120 kg/m2d.
• 1.3 ~ 1.5 times reduction of required surface area of secondary clarifiers.
• Substantial savings in WWTP construction cost due to reduced bioreactors volume and clarifiers area.
• Substantial savings in investment cost of upgrades to existing plants to increase capacity and/or implementation or improvement of BNR treatment processes. Increase of treatment efficiency using existing bioreactors.
• Complete elimination of sludge bulking problems.
• Reduced land area requirement.
• Simple operation.
