ENHANCED WASTEWATER TREATMENTFOR UPLANDS FARM COLD SPRINGS NY

INTRODUCING THE PLANTED BIOLOGICAL REACTOR (PBR)®

A HYBRID MBBR & WETLAND WASTEWATER TREATMENT SYSTEM

What is a Planted Bed Bioreactor?

• A versatile, natural, economical and ecological “on-site” wastewater treatment and water re-use system

• Used for large and small flow “cluster” and communal treatment systems (can be sized like lego pieces to adapt to virtually any environment)

• A 2 component hybrid of MBBR and advanced wetland treatment technologies

• Able to treat all kinds of wastewaters to well below most regulatory limits

• Unlimited lifecycle with easy operation and low maintenance costs

The PBR system is a custom designed flexible insulated concrete form with 2 divisions creating 3 chambers

HOW PBR TREATMENT WORKS• The system consists of two parts, each with 3-chamber components. • The system is capable of treating to less than 10 for CBOD & TSS• An additional treatment component is able to reduce nitrogen to less

than 10 TN mg / litre• Moving Bed Bioreactors (MBBR) biologically treat wastewater by

circulating moving media in aerobic and anaerobic microbial environments.

HOW IT WORKS

PBR TREATMENT DETAILS• An Anoxic tank is used for recycling the effluent for de-nitrification• An Anaerobic bacterium consumes the nitrate producing N2 gas • BOD is knocked down in the first stage of the MBBR treatment • Ammonia is converted to nitrate in the 2nd state of the MBBR treatment• The BAM (Botanical Aeration) is shallow (1 foot beneath water level) for full

nitrification• Solids generated in the MBBR will attach to plant roots and be consumed• Any additional sludge will settle out and be removed annually• An upflow wetland filter is used to “polish” effluent and remove any remaining

solids and consume the balance of oxygen• Treated effluent is sent to a De-Nitrification tank before disposal

De-NitrificationADDITIONAL DENITIRIFICATION• To achieve greater de-nitrification to less than 1mg/litre an additional component

is required• An additional treatment tank is dosed with a carbon source to facilitate biological

removal through the carbon.

PLANTS• Plants enhance biological remediation of organic contaminants found in wastewater

by increasing the population density of microorganisms in the growing media. • MBBR systems are an ideal treatment solution for high-strength wastewater or

siting applications requiring a compact physical footprint

• Upgrading existing treatment plants into MBBR systems can greatly enhance biological nitrogen removal (BNR) – expanding treatment capacity and improving effluent quality with minimal additional footprint expansion.
