Key characteristics:

• Biological treatment process using activated sludge
• Designed to achieve both aerobic and anaerobic microbial treatment in a single-step process
• Fully automatic control
• Applicable to a wide range of municipal and industrial wastewaters

Core patented technologies

The BDP system combines several proprietary technologies:

• Microbiological Technology – Uses low dissolved oxygen and high-concentration activated sludge conditions to maximize the quantity of domesticated microorganisms in the biological treatment tank.
• Aeration Technology – Provides uniform aeration, generates small bubbles with large surface area and slow ascending speed to improve oxygen transfer efficiency.
• Airlift Technology – Uses air as lifting power in redesigned tanks to generate high-flow circulation with less than half the energy consumption of conventional methods.
• High Proportional Cyclic Dilution – Circulates and dilutes influent (up to very high internal recycle ratios) to create a stable water environment for microorganism growth.
• Rapid Clarification System – Separates sludge from water efficiently while continuously circulating sludge at the bottom of the aeration tank.
• Integral Structure – Removes suspended solids (SS), chemical oxygen demand (COD), nitrogen and phosphorus in a single treatment tank, simplifying the process and reducing footprint and operating costs.

Typical removal performance (as described on the website)

Performance depends on application and design, but the website describes the following representative removal capabilities:

• Petrochemical wastewater
• Up to 99% ammonia nitrogen removal
• Up to 95% COD removal
• Up to 95% total nitrogen removal
• Municipal wastewater
• Up to 95% COD removal
• Up to 95% total nitrogen removal
• Up to 75% total phosphorus removal

Efficiency and cost benefits

Compared with conventional wastewater treatment processes, BDP technology is described as providing:

• Less land-use footprint
• Less waste sludge production
• Lower energy consumption
• Reduced operation and maintenance costs

These benefits come from the integrated tank design, high internal circulation, optimized aeration, and automatic process control.

The website describes BDP EnviroTech serving many industries with wastewater concerns, including:

• Mining
• Manufacturing
• Textile dyeing and printing
• Pharmaceutical
• Refining
• Chemical
• Petrochemical and related upstream/downstream facilities

For petrochemical effluent wastewater, the BDP system is described as being able to:

• Remove up to 99% ammonia nitrogen
• Remove up to 95% COD
• Remove up to 95% total nitrogen

BDP systems are designed to accommodate upstream and downstream petroleum and chemical plants.

Municipal wastewater treatment

BDP EnviroTech also serves municipal clients, including small towns and major cities.
