BDP Carpeted Aeration System

Low Consumption, High Efficiency

Carpeted Aeration

Even and fine bubbles are generated in the BDO Aeration System. Compare to the conventional aeration system, BDP Aeration System can thoroughly mix Oxygen with bacteria and create a perfect aeration condition.

Lower DO - Better Bacteria Growth

With a lower DO environment than conventional processes, bacteria is BDP Process has a robust growth rate, which results a high efficiency on containments adsorption and removal.

Non-stop Diffuser Replacement System

A flexible connection is designed to replace single diffuser within 10 minutes, without breaking down the whole wastewater treatment facility.

Anti-clogging Areation System

A “self-cleaning” Aeration System is designed  to operate without maintenance.

Unique Microbiological Treatment

Combines Simultaneous Nitrification and De-nitrification processes into one single treatment unit, by creating a unique biological environment: Low DO (0.3 mg/L) and High MLSS (8 g/L)

Nitrification and De-nitrification

Nitrification Process transforms Ammonia-N to Nitrate, and De-nitrification transforms Nitrate to Nitrogen. By limiting the Diluted Oxygen concentration, BDP Process successfully combines two process together into one single unit. The unique process can achieve up-to 99% Ammonia-N removal rate without adding additional carbon sources.

A Better Solution

Simultaneous Nitrification and De-nitrification process is helping to shorten the treatment process, reduce carbon needs and oxygen consumption.

Hydraulic Circulation Technology

Airlift Circulation and Hydraulic Circulation help BDP System dilute the inlet wastewater and mix with circulated sludge in a timely manner.

Hydraulic Circulation System: Airlift Circulation

–High influent diluting ratio
–Fine living environment for bacteria
–Increase impact resistance
–Low air volume needed, 5% blower capacity

Hydraulic Circulation System: Large Scale Circulation

By diluting the wastewater inflow 20 times with the circulated water, the feeding COD will reduces to about 10% of the original concentration. Which will reduce the organic loading.

Small, Integrated, and Smart

BDP Process integrates all wastewater treatment units into one single integrated treatment tank, which simplifies the process flow, save land footprint, and reduce the investment for pipeline. Most importantly, it is easy to operate, manage and fully auto-control.
