Choosing the right odour management system at the right price

The problem of choosing an odour management system

Wastewater networks and processing plants, industrial processes, agriculture and landfills all generate odours that must be minimised. Regulators and residential neighbours are putting increasing pressure on odour producers to reduce their impact on the environment and people.

A wide variety of odour management systems are available. Some are designed to treat water systems while others target odours in the air phase. Odour management system prices can range from $3,000, but for large operations can cost millions.

How can you choose the right odour management system for your application? How do you avoid making an expensive mistake by investing in the wrong technology that must later be replaced?

Different types of odour management systems

Chemical dosing systems control odours by managing biological and chemical reactions in a wastewater stream. They reduce the production of H2S gas, which is the primary odorous compound from wastewater. These systems require continuous dosing of the wastewater and therefore have an associated operating cost dependant on which chemical is being used.

Carbon filters use activated carbon to remove Volatile Organic Compounds (VOCs) from an air stream. These filters have enormous adsorptive capacity to capture the VOC compounds and remove them from the air. Replacing spent carbon or filter cartridges is an ongoing operating expense.

Biofilters use microorganisms to remove VOCs from an air stream. Conditions must be maintained for optimal microorganism life and activity by controlling the environmental conditions within the biofilter vessel.

Atmospheric vapour and misting systems treat odours in an open air environment. The reactant made from essential oils and a surfactant attract and neutralise odour particles. These systems are used for large diffuse odour sources.

Choosing the best odour management system for your application

For wastewater odour control chemical doing is often considered the most effective choice. This is because the chemical dosing prevents the formation of odour in the first place rather than capture and treatment at the point of emission. Within chemical dosing systems, a choice must be made whether to use magnesium hydroxide, ferrous chloride, or calcium nitrate. It is advisable to get expert advice to help you choose the best chemical and dosing point for your wastewater system. They will also help you to evaluate the wastewater flow rate and chemical composition. These are critical factors when choosing a system and will also impact the chemical dosing price.

When treating air phase sources for odours, carbon filters and biofilters each have advantages and disadvantages. Sometimes biofilters and carbon filters are used in series to optimise the removal of odours from air streams. Experts can help you choose the best filtering system for your needs based on air flow rate, composition, the odour density in the air and the required odour reduction.

Atmospheric vapour and misting systems are used when the source of odour is large and diffuse rather than a point source. Examples are wastewater treatment ponds, landfill sites and agricultural operations. Nevertheless, these systems still reduce odours by up to 90%.

When should I choose a cheaper or more expensive odour management system?

It is always important to obtain expert input when considering a new odour management system. Cheaper solutions like misting systems do not yield the same level of odour reduction as more expensive solutions. Unless you understand clearly the source of odours and the most effective treatment solution, you run the risk of implementing a solution that does not solve your odour problem. This will be a waste of valuable capital resources.

The odour management system price is an important consideration for businesses, but local authorities may also clamp down on odour producers who repeatedly cause complaints. Severe fines and even facility shutdowns can result if the wrong odour management solution is implemented.
