Foggers used to eliminate offensive smells from brewery

Complaints about offensive smells coming from their waste water treatment plant prompted the Mendocino Brewing Company to install new equipment to tackle the problem.

When complaints continued due to new equipment malfunctions, the brewery installed Lafferty Fogger products and stopped all bad smells.

Built in 1997, the Mendocino Brewing company installed its own sewerage plant to treat their waste water and had previously manually mixed the chemicals to balance the treatment pond's pH.

Complaints from neighbours to the city council about bad smells coming from their treatment pond, prompted the brewery to install new equipment in early 2012 that was designed to automatically control the pH of the pond — thereby neutralising odours.

Unfortunately the new equipment malfunctioned and the Mendocino Brewing Company was declared in violation of its odour abatement and with creating a public nuisance.

If the problem was not corrected, the brewery would be forced to shut down until the problem was solved. They then again reverted to manual mixing of the chemicals for the treatment pond — a less than ideal solution.

It was then the Mendocino Brewing Company contacted Lafferty Equipment regarding their range of fogger products.

Lafferty Equipment Foggers are typically used for sanitation in food and beverage facilities and for odour control in food waste processing areas, making them ideal to control the Mendocino Brewing Company's odour problem.

After consultation with Lafferty, the Mendocino Brewing Company installed a 4-Way Pump Fed Fogger, Fogger Controller and Dosatron Panel (central chemical feed system for pump-fed fogging systems) in March 2012.

The 305 4-Way Pump Fed Fogger projects light, damp mist particles up to 7.6m each way and features a solution needle valve to fine-tune the fog particle size. The fogger body is constructed of machined polypropylene and contains a chemical check valve that prevents drips after shutdown.

Lafferty's Fogger Controllers are designed to either manually or electronically control the fogger. The Fogger Controller installed at the Mendocino Brewing Company can be programmed to run the fogger on a cycle determined by individual requirements and on a repeatable cycle until the unit is either switched off or re-programmed.

The Dosatron Panel is a central chemical feed system for pump fed fogging systems. It delivers RTU (Ready To Use) chemical solution to the fogger, by diluting the chemical concentrate in the required ratio via a water-driven proportional dispensing system.

The Dosatron is available in either polypropylene or PVDF construction, with fully adjustable dilution ratios ranges (from 1:3 to 1:5) and choice of seals. It can be supplied as either a complete system, mounted on a panel or within a lockable stainless steel enclosure, for ease of installation and convenience.

Since the installation of the Lafferty products, the Mendocino Brewing Company has had no further complaints of bad odours from their treatment plant.

The Lafferty Fogger products work together to automatically control the treatment pond's pH to the correct level, saving time and money for the brewery, whilst keeping the neighbours happy.
