Odour control

Unlike other agents, which can be costly, potentially hazardous, and targeted at a single issue, ACTI-Mag offers a safe and cost-effective strategy for managing odour.

Excessive odour in sewage network, causing odour complaints ?

Heavy build-up of Fogs layers in the network causing severe corrosion ?

Excess usage of chemicals like lime and alum, & iron salts leading to high maintenance costs ?

Frequent need for vacuum truck cleaning leading to an increase in maintenance costs ?

Hydrogen sulphide (H₂S) gas is produced in sewage with a distinctive and unpleasant rotten egg smell causing frequent odour complaints.

Hydrogen sulphide is present due to anaerobic activity, which favours sulfate reducing bacteria (SRB) and results in the generation of a poisonous rotten egg gas called H₂S. ACTI-Mag effectively locks up H₂S to prevent release as a gas that produces odour and facilitates corrosion. ACTI-Mag is safe to handle and cost effective with many knock-on benefits that reduce treatment costs at the Wastewater Treatment Plant (WWTP).

ACTI-Mag for Odour Control

ACTI-Mag has a higher neutralising value per kilo when compared with caustic while being significantly safer to handle than other traditional alkalis, making it a very safe
and cost competitive option for hydrogen sulphide gas (H₂S) control in sewers.

H₂S is highly toxic…

At just 0.0047 ppm, your customers will start detecting the characteristic ‘rotten egg’ smell of H₂S.

ACTI-Mag NEUTRALISES FASTER

Less chemical consumption

Made with high surface area MgO (200m² /gm), ACTI-Mag provides excellent neutralisation speed and produces less sludge, making it a much more stable product, which stays as a suspension longer compared to other Magnesium Hydroxide slurries.

Low viscosity – flows easily in most dosing systems
Higher neutralisation potential – better cost and usage efficiency
Reduced sludge – easier disposal (less costs)
Safe to handle / non hazardous (corrosion free)
Buffers at pH 9 if overdosed – better stability

not all magnesium hydroxide are made equal.

Unlike many other Magnesium Hydroxide slurries, Calix’s ACTI-Mag is a concentrated (60%) stabilised suspension of magnesium hydroxide.
More solids = Lower required dose.
