The present invention presents an improved method and apparatus for liquid entrainment by a two-phase flow system. The present invention provides an apparatus that recovers liquids by entrainment without experiencing deadhead conditions, choking or dry recovery due to fluctuations in the elevation of the liquid level. The apparatus provides self-regulated two-phase recovery of gas and liquid by construction design, thus eliminating the need for manual adjustments or electronically controlled devices. The enhanced venturi effects of the present invention enhance liquid lift while maintaining the gas recovery point above the liquid at all times to eliminate deadhead conditions.

A method for pollutants using an iron-impregnated, carbon-coated silica sand with the iron containing between to and 16 percent silicon. The invention provides an improved method for performing remeditation of pollutants by dissolved metal reactions while minimizing interferences caused by oxide fouling from oxygen in the water or in the atmosphere. The invention further provides an inexpensive media with high surface area for adsorptive fixation and reductive treatment that yields higher than anticipated reaction kinetics utilizing only low concentrations of iron in the media.

A process for in situ treatment of a contaminated subsurface zone of the earth containing volatile liquid or semisolid organic contaminants, semivolatile liquid or semisolid organic contaminants and/or nonvolatile organic contaminants in liquid, semisolid and/or solidified form which comprises treating said contaminants with an oxidant such as hydrogen peroxide and conducting vacuum extraction to remove volatilized contaminants, volatilized oxidation products of contaminants and/or liquid oxidation products of contaminants. The oxidant application may be made in a contaminated subsurface vadose zone, a contaminated subsurface capillary fringe or beneath the surface of a contaminated water table. Vacuum extraction may be conducted in the contaminated zone itself or, in the vadose zone directly above the contaminated capillary fringe or the contaminated water table and may be utilized, e. g. , to withdraw water containing oxidation products of contaminants.

The permanganate ion and an alkaline earth metal base of calcium and/or magnesium are distributed into the soil by a means of mechanical mixing to destroy contaminants in the soil and groundwater by chemical oxidation. The disclosed method produces a stable, post-treatment, manganese dioxide precipitate that does not adversely effect the ground water with high dissolved manganese concentrations. The permanganate salts may include potassium, magnesium or sodium permanganate, and the preferred alkaline earth metal bases may include calcium oxide, calcium hydroxide, magnesium oxide and magnesium hydroxide. Dolomite quick lime may be used to supply an inexpensive source of the desired calcium and/or magnesium base. The calcium and/or magnesium base may be added before, during or after the addition of the permanganate salt.
