Frequently Asked Questions (FAQs)

How do I know which nutrients my plant is lacking?

A sample from the plant will be analysed in the OMEX laboratory.

Testing will include nitrogen and phosphorous, metals with ICP equipment, methane potential with their AMPTs equipment (Automatic Methane Potential Test) and neutralisation.

 

Which samples should I send to the OMEX laboratory for analysis?

For an aerobic wastewater plant OMEX requires a sample of the influent, the aerobic reactor and final discharge effluent.

For an anaerobic system OMEX requires a sample of influent, bio-sludge and effluent. Usually 200 ml of each is sufficient for laboratory analysis, along with details of the treatment problem. When the process is stable, only samples of bio sludge are needed with the occasional sample of influent and effluent.

 

Why do Digesters need trace elements?

Most digester feedstock lacks in essential elements such as Co, Fe, Ni and Se which are essential to the health and efficiency of a plants’ biology. OMEX TEAs can provide and augment these essential elements in a fully bioavailable form.

OMEX has a proven track record in the optimisation of Anaerobic Digester and Biogas Plants worldwide, supplied with full laboratory back up. OMEX TEAs show a proven increase in biogas volume, an increase in Biogas quality (Methane content increases) and increased digester stability.

 

How do I know how much product I need to dose?

OMEX products have a standard daily dose rate which is adopted in the initial start-up phase. From there a plants performance will be strictly monitored and the dose rate will be increased or decreased dependant on its performance.

 

Does OMEX provide equipment to dose its products?

OMEX supplies, commissions and installs dosing systems for septicity control and magnesium hydroxide solutions. The standard dosing unit is 2500 Litre capacity but sizes range from 1350 up to 10,000 Litre. The dosing systems are fully commissioned and installed and advice will be given on the daily dose rate required.
