The effect of additives on the treatment of oil-in-water
A simple batch vacuum evaporation process for the treatment of several oil-in-water (O/W) emulsions is reported. The experiments were carried out with waste emulsions from an industrial copper rolling process and with model emulsions prepared in the laboratory.

Evaporation rates of water and oil from creamed oil-in-water emulsions have been measured under conditions of controlled gas flow. The continuous water phases of the emulsions evaporate at rates equal to that for pure water under the same conditions. The evaporation rates of dispersed oil drops are retarded, relative to nonemulsified oil, by factors ranging from 1 to 20.

Surfactant-free emulsions were prepared by mixing water and oil (toluene, n-octane, gasoline and diesel, respectively) in 100:1 or 1:100 (v/v) and the mixtures were sonicated for 1.5 h to obtain

Review: Porous Metal Filters and Membranes for Oil–Water
In recent years, oil–water separation has been widely researched to reduce the influences of industrial wastewater and offshore oil spills. A filter membrane with special wettability can achieve the separation because of its opposite wettability for water phase and oil phase. In the field of filter membrane with special wettability, porous metal filter membranes have been much investigated
Industrial wastewater treatment requires appropriate technologies as well as proper application. After performing a full system audit and all requisite testing, ChemTreat can customize a wastewater treatment process that optimizes chemical usage, effluent flow rates, and off-site treatment costs.
Waste Water Treatment: Electrocoagulation Technology
In the past few decades it has been used for the treatment for the water containing foodstuff wastes, oil wastes, dyes, suspended particles, chemical and mechanical polishing waste, organic matter from landfill leachates, defluorination of water, synthetic detergent effluents, mine wastes and heavy metal-containing solution.
However, this treatment is convenient and may be more efficient to produce high quality water. Electrodes with Aluminum (Al), Iron (Fe), Steel (St) and graphite are generally the best suited to
- Can cationic polyacrylamide be used to quantify polymer zeta potential?
- However, both cationic and anionic polyacrylamides were used to quantify polymer–shale zeta potential. The anionic polyacrylamide concentration was 0.1–0.2 wt%, such that the concentration is well above C * (critical overlap concentration) and below C ** (critical entanglement concentration).
- Do charged polyacrylamides interact with shale?
- Interaction of polymer-containing injected fluids with shale is a widely studied phenomenon, but much is still unknown about the interaction of charged polyacrylamides such as anionic and cationic polyacrylamides with shale.
- What is cationic polyacrylamide (C-PAM)?
- Cationic polyacrylamide (C-PAM), copolymerized from acrylamide and substituted acrylate or acrylamide segments, offers an alternative to PHPA and exhibits high stability under high TDS conditions 28.
- Is cationic polyacrylamide a good fluid additive?
- It is recommended to use anionic polyacrylamide because of its minimal interaction and also compatibility with other fluid additives. Due to the cationic polyacrylamides interacting strongly with shale, it can potentially cause formation damage. Both the rheological studies and the zeta potential tests gave the same results.
