- Electrochemical technologies have been broadly applied in wastewaters treatment, but few studies have focused on comparing the performance of the different electrochemical processes, especially when used to treat highly-polluted streams.
- Internal concentration polarization (ICP) is a major issue in forward osmosis (FO) as it can significantly reduce the water flux in FO operations.
- Water scarcity, its necessity in food production, and environmental protection in the world have forced human beings to seek new water sources.
- The treatment of radioactive iodine waste is a difficulty in the field of nuclear waste disposal.
- Moving bed biofilm reactor (MBBR) is a robust, flexible and compact technology for treatment of medium to high strength wastewater.
- Effluents from dyeing and finishing processes of textile industry contain strong colour, dissolved solids, high pH and possibly heavy metals.
- In recent years, electric oxidation of urea has become an effective method to treat wastewater.
- Low salinity/engineered water injections (LSWI/EWI) have gained popularity as effective techniques for enhancing oil recovery.
- Reverse osmosis (RO) membranes are prone to fouling, which increases the cost of operation and decreases water recovery.
- Increasing public interest in the environmental impact of technical machinery has led to the development of new hydraulic fluids.
- cross-flow membrane filtration, fouling results from material deposit which clogs the membrane inner surface.
- Nanotextured materials have been used extensively for water treatment and purification to minimize wastewater pollution from factories and oil spill accidents from damaging our ecosystem.
- Marine fouling can be a serious problem in the shipping industry, since it increases the surface roughness of the hull and hence its frictional resistance to its movement through water.
- a paper mill's water circuit, normal runnability of the paper machine is often disturbed due to buildup of hydrophobic dissolved and colloidal substances (DCS), such as wood pitch, white pitch, and stickies.
