Microplastics in Sewage Sludge: Effects of Treatment
Waste water treatment plants (WWTPs) are receptors for the cumulative loading of microplastics (MPs) derived from industry, landfill, domestic wastewater and stormwater. The partitioning of MPs through the settlement processes of wastewater treatment results in the majority becoming entrained in the sewage sludge. This study characterized MPs in sludge samples from seven WWTPs in Ireland which
In recent years, new advanced oxidation processes based on the electrochemical technology, the so-called electrochemical advanced oxidation processes (EAOPs), have been developed for the prevention and remediation of environmental pollution, especially focusing on water streams. These methods are based on the electrochemical generation of a very powerful oxidizing agent, such as the hydroxyl
A new innovative advanced wastewater treatment technology
A new innovative advanced wastewater treatment technology. Highly effective and environmental friendly technology APOP is a new concept for advanced photo oxidation processes at wastewater treatment plants. By using the APOP-concept a non-hazardous effluent from wastewater treatment plant • No risks for recipient water bodies and eco
Treatment of produced water is an urgent matter in view of the high daily volume. Different processes have been described for the treatment of such effluents, but the most frequently used are chemical destabilization and electrochemical destabilization, Biological processes are rarely used since these effluents usually contain biocides [2] .

Taehwan Jun's 3 research works with 10 citations and 139 reads, including: Removal of phosphate and suspended solids by electrocoagulation coupled with woven fabric membrane at pilot plant
Similar results were shown by Aslan and Kapdan using cultures of C. vulgaris in synthetic wastewater (10 days of treatment) where 78% of phosphorus was removed by keeping N/P = 2:1. In contrast Wang et al. [9] showed that up to 90% of phosphorus was removed from wastewater (9 days of incubation) by Chlorella sp. (N/P = 6:1).
Recent developments in polysaccharide-based materials used
The crosslinking agents cited above are neither safe nor environmentally friendly. So, recently, other water-soluble crosslinking agents have been proposed, such as sodium trimetaphosphate , sodium tripolyphosphate , , phosphorus oxychloride or carboxylic acids .For example, citric acid was selected taking into account its non-toxicity, its wide use in the food industry as a safe natural

Prospects of implant with locking plate in fixation
Effective fixation of fracture requires careful selection of a suitable implant to provide stability and durability. Implant with a feature of locking plate (LP) has been used widely for treating distal fractures in femur because of its favourable clinical outcome, but its potential in fixing proximal fractures in the subtrochancteric region has yet to be explored.
We study dissolution in a chemically heterogeneous medium consisting of two minerals with contrasting initial structure and transport properties. We perform a reactive transport experiment using CO2-saturated brine at reservoir conditions in a millimeter-scale composite core composed of Silurian dolomite and Ketton limestone (calcite) arranged in series.

- Are cationic polyacrylamide copolymers bad for the environment?
- Cationic polyacrylamide copolymers (PAMs) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land. Concern has been expressed since little is known about the degradation of PAMs in soils.
- What are cationic polyacrylamide copolymers?
- Cationic polyacrylamide copolymers (PAMs) are a group of water-soluble polymers with a wide range of applications in industry, food processing, agriculture and waste management. One of the major applications for PAM is sludge dewatering in municipal waste water treatment plants (MWWTPs).
- What is cationic polyacrylamide (CPAM)?
- Cationic polyacrylamides (CPAMs) are widely utilized due to their excellent performance in flocculation and sludge dewatering . Numerous studies have been conducted on CPAM synthesis technologies, including grafting, free radical polymerization, and polymer modification .
