Researchers at North Caucasus Federal University (NCFU) have patented a novel method for keeping water intakes free from shellfish and other biofouling. The university’s press center reported the development, noting that the approach relies on an innovative electrical system designed to deter mollusks from adhering to intake infrastructure. The project was described as a cost-effective alternative to traditional antifouling techniques (attribution: NCFU press center).
In practical terms, the system uses a dedicated direct-current power source to create an electrostatic environment that discourages shellfish from attaching to metal surfaces. The positive electrode connects to a metal conduit, while the negative electrode is linked to the cathode. The researchers stressed that this method significantly reduces operational expenses compared with conventional antifouling measures (attribution: NCFU press center).
The team explained that, in hot climates, pipelines at water intakes frequently accumulate molluscs and other aquatic organisms. This biofouling buildup can lead to reduced internal pressure and impaired flow. By applying an electrical charge to the pipe’s inner surface, the system forms a protective barrier that minimizes biological growth without relying on chemical treatments (attribution: NCFU press center).
Separately, researchers at the Ocean University of China in Qingdao recently announced a different breakthrough. They developed a probiotic delivery method based on complex sugars that facilitates oral administration and targets delivery to the intestines. This technique was reported to markedly improve the survival rate of beneficial bacteria as they pass through the digestive system (attribution: Ocean University of China press release).
In related scientific progress, educators and scientists continue to pursue approaches that safeguard vulnerable populations. Earlier work by researchers in the field has examined methods to support children facing life-threatening Batten disease, aiming to identify treatment pathways that may improve quality of life and long-term outcomes (attribution: various peer-reviewed reports).
