Activated Carbon Eliminates Odours
Activated Carbon has been shown to be very effective in eliminating odours emanating from commercial cannabis cultivation greenhouses. The molecules creating the odours become trapped in the pores of the activated carbon, where they remain, ensuring the surrounding environments remain free from the smells created by cannabis cultivation.
Deep Bed Carbon Adsorbers
HDB™/HECA™ Deep-bed Activated Carbon Adsorbers
AST Canada uses Barnebey Sutcliffe® deep-bed activated carbon adsorbers which are designed for greater than 99.9% removal of volatile organic compounds (VOC), odours where high air flow or high contaminate concentrations exist. To minimize service costs, deep bed adsorbers are sized to provide an approximate annual quantity of activated carbon for the removal of specified contaminants.
HDB™/HECA™ Deep-bed Activated Carbon Adsorbers
The standard configuration for a deep bed carbon adsorber is a horizontal bed (HDB) of 2 to 5 feet deep. To assist in long fan life, systems are designed to pull air through the bed and are generally equipped with pre- and post-particulate filters. For applications where a minimum equipment footprint and/or low-pressure drop is needed, we also offer a HECA deep bed carbon adsorber, which utilizes vertical bed design. Standard dimensions and pressure drop data are provided.
Greenhouse Odour Control Equipment
VOC - Volatile Organic Compound Control
Our deep bed carbon adsorbers are easily modified for a variety of applications including atmospheric emission control and worker protection. These durable activated carbon systems are available over a flow range of 100 to 20,000 cfm with the flexibility to allow you to adapt to constantly changing regulations from local Air Pollution Control District (APCD), EPA Air Quality Act, OSHA Regulations, EPA NESHAP’s regulations, and ASHRAE’s Indoor Air Quality Standards.
Indoor Ventilation Filters for Odour Control
Ninety percent of a person’s life is spent indoors. Studies have shown that in many commercial, industrial, and public buildings levels of nuisance odours and pollutants that can be two to five times greater indoors than outdoors. Odours and irritants increase business costs through productivity losses, sick days, and medical expenses as well as employee and community concerns and complaints. Deep bed units can remove odours with correct activated carbon selection.
Activated Carbon Selection
AST Canada offers over 500 different carbon products and can design a system to meet your facility’s odour control needs. We provide the greatest level of technical support from application computer modelling to laboratory performance testing to pilot units for field testing. Many of the deep bed systems and carbon solutions we provide are custom tailored to exact requirements. Contact AST Canada for help in selecting the proper activated carbon product for your needs
Complete Odour Control Systems
Turnkey Engineered Odour Control Units
The complete deep bed carbon units, including dust filter, carbon section, final filter, and blower, are available in capacities from 100 to 20,000 cfm and may be customized with respect to carbon bed depth, guard beds, dampers, pressure gauges, etc., to meet your requirements. We engineer your deep bed carbon adsorber as a complete unit. Systems can be manufactured to include fans, motors, dampers, isolation and bypass pre- and post-filters, controls, and exhaust stacks so that all you need to do is provide the inlet connection.
Operational Maintenance of Your Odour Control System
When in service, we can provide a sampling of the carbon bed to test for remaining activated carbon life to assist in developing an activated carbon exchange schedule. Once the carbon is spent and needs to be exchanged, our field service team will remove the spent carbon and install fresh carbon in a single day to minimize downtime to your operation. We will assist you in profiling the spent carbon and arrange that the spent carbon be recycled at one of our plants, removing your liability. We offer these products and services so that you may “one-stop shop” and hold one vendor accountable for your activated carbon system.
Modes and Features of Deep Bed Carbon Adsorbers
Deep Bed Adsorber Operational Modes
Deep bed adsorbers operate in one of three modes:
- outside air only
- full recirculation
- recirculation with outside air make-up.
Features
- These deep-bed adsorbers provide greater than 99.9% contaminate removal.
- Provisions to preclude bypass in the unlikely event of bed settling are incorporated in the design.
- The system utilizes a gasketless, continuously welded housing of high-quality stainless steel to preclude the bypass of contaminated air around the carbon bed.
- The fan assembly comes with a severe duty, high-efficiency motor.
- Motor speeds are kept to a minimum to ensure quiet operation and maximum life.
- Low static pressure drop.
- Minimal footprint.
- The deep bed low maintenance, activated carbon adsorber system is also configured to enable you to monitor carbon usage and take the guesswork out of determining the remaining carbon bed life.
- Sample ports upstream can be used to test for inlet VOC concentrations and downstream sample port to sample final outlet concentrations.
- Three sample ports are located evenly throughout the carbon bed indicate the location of the mass transfer zone and the remaining amount of unused activated carbon in the system.
- Lower maintenance costs than using several single units.
- Carbon exchange services.
- Available in carbon steel, aluminum, and stainless steel. Other materials offered as a special order.
