AP23489574 "Modified activated carbon filter system for efficient removal of organic substances and microplastics while slowly filtering recycled water"

Relevance

The relevance of developing water treatment technology, including the removal of dissolved organic substances and microplastics, is driven by the growing issues of water pollution and the need to improve water quality. In recent years, there has been an increase in the pollution of rivers and water bodies worldwide, leading to significant environmental and economic consequences. In Kazakhstan, the state of water resources is also deteriorating, particularly due to the increase in wastewater volumes containing toxic substances and microplastics. The application of the proposed wastewater treatment technology will significantly reduce water pollution and enable the efficient reuse of treated water, contributing to sustainable development and environmental protection.

Purpose

Development of technology for processing hard-to-enrich polymetallic raw materials using environmentally friendly reagents. The proposed technology using environmentally friendly reagents will improve the technological performance of flotation enrichment of difficult-to-enrich polymetallic raw materials containing precious and rare metals by 3-5%, while reducing the consumption of the proposed reagents by 10-20%.

Expected and achieved results

As a result of this project, sorbents were synthesized from agro-industrial waste (carbonation, activation and impregnation with FexO were carried out). The characteristics of the synthesized AU were investigated. A laboratory prototype of the filter column was assembled (sand, a mixture of sand and chemically activated carbon and modified FexO activated carbon with a self-generating biofilm). The scientific novelty of the proposed universal multimedia slow filtration filter lies in the ability to extract both MOAT and MP by improving the oxygen reduction reaction and electron transfer efficiency.
