OMEX manufactures and supplies nutrients and neutralisers for all types of biological wastewater treatment and biogas plants. OMEX's range of products is designed to ensure optimised operation and overcome potential problems that can occur with modern effluent and septicity treatment.

For anaerobic digesters OMEX specialise in customised solutions to meet the individual micronutrient needs of specific anaerobic systems and operational requirements.
