This chapter explores the various techniques used to manage and eliminate "nasty gas," focusing on the application of regenerative blowers in different scenarios.
1.1 Air Stripping: This technique involves physically removing VOCs from contaminated water by exposing it to air. The blowers provide the necessary air flow to effectively transfer VOCs from the water to the air phase.
1.2 Biofiltration: This method uses a biological process to break down VOCs. The blowers move contaminated air through a bed of biological media, where microorganisms consume and degrade the pollutants.
1.3 Thermal Oxidation: This process utilizes high temperatures to oxidize and destroy VOCs. Blowers provide the necessary airflow to transport the contaminated air to the oxidation chamber.
1.4 Adsorption: This technique uses materials with high surface areas to capture and bind VOCs from contaminated air. Blowers are used to draw the air through the adsorbent bed, enhancing the efficiency of the process.
1.5 Condensation: This method utilizes cooling to condense and remove VOCs from contaminated air. Blowers are used to move the air through the cooling system, promoting condensation.
This chapter dives deeper into the various regenerative blower models available and their specific applications in "nasty gas" management.
2.1 Centrifugal Blowers: These blowers use centrifugal force to move air and are well-suited for handling large volumes of gas at moderate pressures. They are often employed in large-scale air stripping or biofiltration systems.
2.2 Positive Displacement Blowers: These blowers use a rotating impeller to trap and displace a fixed volume of air with each rotation. They offer high pressure and flow rates, making them suitable for applications like landfill gas recovery or industrial exhaust gas handling.
2.3 Regenerative Blowers: These blowers utilize a unique design that recovers energy from the expelled air, resulting in higher efficiency compared to traditional blowers. They are ideal for applications requiring high pressure and low energy consumption, such as biofiltration systems or small-scale air stripping.
