Activated Carbon Filters

The Midland Resource Recovery (MRR) activated carbon filters are designed to eliminate mercaptan odor problems at odorization stations. Use the filtration systems either throughout the regular operation of your odorizer or during maintenance or odorant refills. Additionally, the odor removal system is excellent during a pressure release event, odorant transfers, equipment failures or odorant spills.

Carbon Filters

The MRR activated carbon filters are an environmentally responsible and proactive solution. The patented design provides long-lasting and cost-effective odor removal through adsorption, where the odor compounds become trapped inside the activated carbon bed. The filters consist of a bed of activated carbon and an air distributor designed to ensure maximum distribution throughout the activated carbon, enclosed in a DOT-approved drum. The air inlet and outlet are located on top of the drum, permitting easy handling and transportation.

The units are transferable and can be moved to different stations. The motors can come attached to the drum or detached. The detached option allows the user to move the motor to stationery drums at other sites.

A stationary EZ Carb setup is ideal for an odorization room where the user can flip an electrical switch and power on the filter before entering.

Active Filters for Mercaptan Odor Removal

EZ Carb active filters are equipped with an explosion-proof 1/3 hp blower (200 CFM design flow) which is either mounted on top of the steel drum or detached (connected to the drum by a hose). The active filtration systems are Class I Div I approved.

These filters are available in 30 and 55-gallon drums. The 55-gallon drum assembly with a blower attached (EZ-055A) weighs approximately 270 lbs.

Passive Filters

EZP Carb passive filters are housed in 15-gallon plastic drums or 55-gallon steel drums.

In addition to our standard models, we design and install custom-made filtration systems to meet specific client needs.

"Over the years, Midland Resource Recovery has provided Union Gas with safe and dependable odourant services such as odourant system repairs, bypass odourant system replacements, emergency spill response, and odourant waste disposal. Odourant is a product with a potential that is often under-estimated; however, MRR fully understands its impact, and as a result, holds itself to the highest standard of work. Even a small odourant vapour release while completing a task is unacceptable to MRR. Furthermore, in the event of an odourant related emergency, MRR would be the first to receive a call, as they have the expertise and knowledge to assist in a time of crisis. This has been proven time and time again in our relationship throughout the years."
