  • Eco-toxicity of oily wastes containing TENORM

    Oily wastes are considered as one of the most hazardous waste types. Additionally to petroleum components, they can contain radioactive elements. This study aimed to estimate the toxicity of four raw and two treated waste samples obtained from petroleum production yard. Eight elutriate bioassays using plants ( Raphanus sativus and algae Scenedesmus quadricauda ), crustacean ...

  • Fabrication of circular shaped ceramic membrane using mixed clays by uniaxial compaction method for the treatment of oily wastewater

    Circular shaped ceramic membrane was fabricated using inexpensive mixed clays by uniaxial compaction method and subsequently fired at 900°C. TGA analysis demonstrates that the minimum sintering temperature required to fabricate the membrane is above 800°C. A volume median diameter d(0.5) of the raw material mixture is found to be 2.78 µm. XRD analysis verifies that the membrane undergoes phase ...

  • Oily waste disposal case study

    The data shows that the total pounds of oil on the land farm has gradually increased from October 1983 through to March 1988. Our products were added one month later, April 1988. The graph shows that despite adverse conditions, including a dry and hot summer, the land farm degraded almost ten times the oil it had in previous years using our ...

  • Case study - Oil emulsion and cleaning parts wastewater

    Customer The company is the only car manufacturer in Slovakia producing engines. In the Slovak facility, they produce gasoline engines by five production lines, four metal cutting lines and one assembly line. Customer needs Disposal of huge not dischargeable oily waste water is one important issue that the company has set out to exploit. The goal ...

  • Oily wastewater treatment by ultrafiltration using Taguchi experimental design

    In this research, results of an experimental investigation on separation of oil from a real oily wastewater using an ultrafiltration (UF) polymeric membrane are presented. In order to enhance the performance of UF in API separator effluent treatment and to get more permeation flux (PF), effects of operating factors on the yield of PF were studied. Five factors at four levels were investigated: ...

  • Effect of membrane characteristics on the performance of membrane bioreactors for oily wastewater treatment

    Influence of membrane material and pore size on the performance of a submerged membrane bioreactor (sMBR) for oily wastewater treatment was investigated. The sMBR had a working volume of about 19 L with flat sheet modules at the same hydrodynamic conditions. Five types of micro- and ultra-polymeric membranes containing cellulose acetate (CA), cellulose nitrate (CN), polyamide (PA), polyvinylidene ...

  • Experimental investigation of oily wastewater treatment using combined membrane systems

    Investigations were carried out for purification of oily wastewater by a combined of ultrafiltration/reverse osmosis (UF/RO) processes. Laboratory-scale UF using polysulfone (PS) and polyacrylonitrile (PAN) membranes were employed with typical oily wastewater collected from API unit of Tehran refinery. The PAN membrane showed higher rejection, more permeation flux and less fouling resistance than ...

  • Novel pretreatment enables performance of MBR installed to treat oily wastewater

    Abstract Two new integrated systems processes, gas-energy-mixing (GEM) flotation – electrochemical catalytic oxidation (ECO) – membrane bioreactor (MBR) and ultra-filtration (UF) – ECO – MBR, were tested in industrial-scale pilots of 200L/h to 3000L/h for the treatment and reuse of steel mill cold-rolling emulsion wastewater. The operation parameters and mechanisms of ...

  • VSEP`s low operating cost and superior performance provide a high-tech alternative for oily wastewater processing

    A unique membrane filtration system has been installed at several major waste oil hauling operations and manufacturing plants that handle or produce oily wastewater. The system manufactured by New Logic, of Emeryville California near San Francisco, is also being used to process used crankcase waste oil and produce filtrate that can be sold as a higher value bunker oil. The V✧SEP, ...

  • Performance of Aerobic MBR Treating High Strength Oily Wastewater at Mesophilic –Thermophilic Transitional Temperatures

    AbstractThe performance of an aerobic membrane-coupled bioreactor (MBR) operating at mesophilic- thermophilic transitional temperatures (40°C) treating oily rendering wastewater has been evaluated in terms of COD, BOD5, oil and grease, solids and ammonia removal at 5 and 10-day HRT. The COD removal efficiency increased from 78% to 96%, BOD5 removal from 87 to 99% and oil and grease removal from ...

  • Skimming Oily Wastewater

    As large generators of oily wastewater tighten effluent controls, the U.S. Environmental Protection Agency (EPA) is targeting smaller generators. Some of the firms receiving their attention are smaller manufacturing plants, automotive garages, mobile equipment service shops and truck farms. Many of these firms do not have access to a sanitary sewer system that will accept oily wastewater. Because ...
