Misting system combats 'eau de grease trap'

Grease traps are not known for their pleasant fragrance, so when a new facility was proposed in Dubbo, NSW, to treat greasy liquid waste from local businesses, one of the conditions of its approval was the inclusion of an effective odour control system.

Odour-neutralising agent supplier For Earth approached Tecpro Australia to design and fabricate a misting system for the facility to eliminate the odour.

“As you’d expect with a waste facility, unpleasant odours can occur intermittently within the building, particularly when new waste is received and unloaded,” said Andrew Cooke, sales manager with Tecpro Australia.

“Our design features high-pressure pipes that run across the ceiling of the facility,” said Cooke. “Each pipe is fitted with a series of fogging nozzles that discharge a powerful plume of mist. This mist incorporates the odour-neutralising solution, enabling nasty smells to be eliminated.”

The system also features a high-pressure pump, along with a timer that allows for duty cycles to be adjusted as needed.

“For example, the misting system can be run for 20 seconds on and 20 seconds off, or this could be increased or reduced, depending how busy the facility is,” said Cooke. “And because the mist droplets are so fine, they evaporate quickly so water doesn’t pool in the facility.”

Feedback has been very positive about the success of the odour-neutralisation system. “If smells occur, they are removed completely within a couple of minutes of the system starting up,” said Cooke. “The system can also be used to reduce the air temperature inside the building, which is especially useful in summer. Naturally, this makes it a much more pleasant place for anyone who works within the facility.”
