Gravimetric and chemical treatment with land-farm application discharge had significant design shortcomings during routine process upsets, becoming under-sized as production increased, or as heavy rainfall resulted in uncontrolled storm runoff of the wastewater. API O/W/S technology certainly can’t be expected to be deployed effectively for remote oil and gas fields or offshore sites produced water as a package treatment plant option. Various new configurations of separation technology have expanded oily-wastewater treatment options, everything from hydro-cyclones to coalescing plate filters, membrane filtration, even the use of ultra-filtration to separate and concentrate pre-treated process waste streams. While these methods offer good process response through a wide range of flows, and may meet US total hydrocarbon cleanup regulations, they are incapable of meeting proposed European environmental protection legislation, and each creates a reject side-stream of highly contaminated effluent, which must be disposed of as haz-waste.
