Synthesis of graphene oxide–SiO2 coated mesh film and its properties on oil–water separation and antibacterial activity
Oil–water separation has recently become a worldwide challenge due to the frequent occurrence of oil spill accidents and increasing industrial oily wastewater. In this work, the multifunctional mesh films with underwater oleophobicity and certain bacteriostatic effects are prepared by layer-by-layer assembly of graphene oxide-silica coatings on stainless steel mesh. The mesh film exhibits ...

Polyvinyl resin plant - Case study
PROBLEM: A polyvinyl chloride resins plant discharges oil into its wastewater. The oil, which is used in the polymerization process, frequently exceeds state limits in the wastewater, which could mean a $53,000-per-day fine. To avoid this, the plant has been metering its discharge from a sump into the public water system in smaller amounts — a costly and inefficient answer. Additionally, ...

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 ...

Enhance the efficiency of Oil/ Water separators with Oil skimmers
The American Petroleum Institute (API) oil/water separator was developed by the API and the Rex Chain Belt Company and was first installed in 1933 at the Atlantic Refining Company in Philadelphia, Pa. Simply stated, the API oil/water separator is a device designed to separate oil and suspended solids from industrial wastewater sources, such as those found in oil refineries, petroleum handling ...

Treatment of petroleum refinery wastewater by distillation-assisted catalytic oxidation under low temperature and low pressure
A distillation-assisted catalytic oxidation (DACO) process under low temperature (100 °C) and atmospheric pressure was investigated to treat heavily contaminated wastewater from oil refining industry. The DACO experiments were carried out in a distillation batch reactor, using CuO/γ-A12O3 as catalyst. The experimental temperature was kept at 100 °C and H2O2 oxidant was supplied into the reactive ...

Nigerian drilling platforms wastewater treatment
Wastewater on a self-contained drilling platform comes from several sources. The following examples are samples obtained from the seven oil-drilling platforms off of the coast of Nigeria. The first platform had samples from the industrial laundry, kitchen, emulsified wastewater, cutting oily-water and drilling mud. The samples were treated individually and then combined so as to simplify the ...

Brakebrush Brothers - Simple way to reduce costs and increase profit - Case study
Packaged-food producers frequently use and then must discard large batches of cooking oil used in their process. Usually they drain most of the oil directly from equipment, but they must remove residual oil by regularly washing fryers, ovens, conveyors, and other machinery. The oil mixes with the wash water and becomes part of the plants wastewater stream. Having oil in wastewater complicates ...

Model 6V – Less maintenance than belt skimmers - Case study
Problem: A fabricated steel manufacturer was using belt skimmers at the discharge mouth of two retention ponds of waste oil and water. Debris such as sticks and rubbish also ended up in the outdoor ponds and would get caught in a screen covering the intake of the belt skimmer. If workers didn’t clean the screen daily, a dam of debris would form and prevent oil from entering the belt ...
