    Treatment Technologies: Reverse Osmosis, Electrodialysis, Weak Acid Cation Exchange,

    Solids Removal(sludge,slurry ect.)

    Treatment technologies: Filtration, Focculation

    Oils and Grease removal

    Treatment technologies: Gravity Tanks/ Pits,  API oil-water separators or plate packs, chemical treatment via DAFs, centrifuges, media filters and hydrocyclones

    Toxic Metals removal

    Many organic materials, metals (such as zinc, silver, cadmium, thallium, etc.) acids, alkalis, non-metallic elements (such as arsenic or selenium) are generally resistant to biological processes unless very dilute. Metals can often be precipitated out by changing the pH or by treatment with other chemicals. Many, however, are resistant to treatment or mitigation and may require concentration followed by landfilling or recycling. Dissolved organics can be incinerated within the wastewater by the advanced oxidation process
