Systems and methods to enhance the removal of inorganic contaminants, including metals, from hydrocarbon feedstocks at a refinery. One or more embodiments of such systems and methods may be used to provide a renewable hydrocarbon feedstock having a reduced amount of metal contaminants. The reduction of metal contaminants in the renewable hydrocarbon feedstock mitigates catalyst fouling and/or deactivation during downstream refinery processing of the renewable hydrocarbon feedstock.

Systems and methods to separate water and remove solids from a pre-treated and unfiltered renewable feedstock at or separate from a refinery. Such systems and methods may be used to provide a reduced-contaminant and reduced-solid renewable feedstock for further refining.

The invention relates to the methods for sewage treatment contaminated by mechanical impurities, fats, proteins and other organic and inorganic compounds, and can be used for purification and water disinfection contaminated by heavy and radioactive metals, saturated or unsaturated fats, filtrate from landfills for solid household waste, disposals of meat processing plants, and water contaminated with oil and petroleum products. The method for treatment and disinfection of industrial wastewater includes flotation, electrocoagulation and filtration. The new is that the method also provides: mixing water with powder hydrophobic carbon-based sorbent with high absorbing capacity; filtration of a suspension of water and a carbon sorbent on a rubber-based hydrophobic sorbent; decomposition of saturated and unsaturated fat, oil, petroleum products and other organic substances accumulated on carbon and rubber sorbents; floatation in flow mode with the addition of hydrogen peroxide; recovery of the active substance in the presence of hydrogen peroxide; and its further reuse; electrocoagulation in flow mode with water saturation with oxygen and hydrogen, formed on indispensable carbon or metal electrodes, and on the active substance based on the of aluminum, titanium, sodium, tin, copper, and other metals; water disinfection by electro-cavitation; generation of active substance based on the iron and titanium atoms; water filtration on the precoat filter, filtering on activated carbon filter.

A method for treating an oil-containing medium including oil or grease or both oil and grease includes the steps of combining algae with an oil-containing medium and allowing the algae to engulf or uptake at least a portion of the oil or grease in the oil-containing medium. A mixture for treating oil or grease or both oil and grease includes an oil-containing medium including oil or grease or both oil and grease and phagotrophic algae that engulf or uptake at least a portion of the oil or grease in the oil-containing medium.

A mixed fluid separator apparatus includes an overload protection chamber that prevents a large and sudden influx of oil from fouling a coalescing separator. To prevent sudden influx of a large concentration of oil from overwhelming the coalescing separator, a separate overload protection chamber is connected to a main coalescing separator apparatus. The overload protection chamber includes a water drain (majority water with some oil) to the main coalescing separator apparatus and an oil overflow (majority oil with some water) to drain excess oil when necessary to prevent overfilling of the coalescing separator apparatus. The overload protection chamber functions to rapidly separate and remove heavy concentrations of oil, protecting the main coalescing separator apparatus.
