Microorganisms destructors of organic compounds contained in the Kremenchug reservoir and water treatment system of heat power station have been distinguished and identified. This system does not completely remove microflora at all stages of technological process that results in infestation of ion-exchange resins of the 1st stage filters for water desalting with microorganisms. The reasons have been established of the 1st stage desalting filters infestation by the reservoir water microflora. It is necessary to form a complex approach to solution of the problem of preventing the accident situations: microbe infestation of ion-exchange resins of water-desalting filters in the system of chemical water treatment of heat power stations.

Intestinal infections affect approximately 450 million people globally, predominantly impacting children and immunocompromised individuals in low- and middle-income countries (LMICs) due to inadequate water, sanitation, and hygiene (WASH) conditions, poverty, malnutrition, and low literacy. In Kenya, the prevalence of intestinal infections is elevated by warm tropical climates and socioeconomic factors. This scoping review evaluates the national prevalence, risk factors, and contamination sources of intestinal protozoa in Kenya, using a One Health approach to synthesize existing data from various human, animal, and environmental studies.

In waterflooding development of narrow channel reservoirs, the water cut rises quickly, and the reservoir becomes nearly fully flooded, yet oil recovery remains low. The narrow strip sand body and long-term water injection create a complex oil and water distribution, making it difficult to evaluate the degree of reservoir utilization during waterflooding. This paper establishes a practical streamline method to quantitatively characterize the waterflooding mobilization degree of narrow channel reservoirs.

The Hammam Faraun, Matulla, and Nubia formations in the Ashrafi oil field, in the southern Gulf of Suez, Egypt, are key hydrocarbon reservoirs with significant economic importance. These formations, characterized by their favorable reservoir properties and structural settings, play a crucial role in oil and gas accumulation. Their study provides valuable insights into regional petroleum systems and guides exploration and production activities.

The health burden of waterborne nontuberculous mycobacteria (NTM) is a rising concern. While the water supply systems can serve as a potential reservoir for NTM, their abundance, diversity, and transmission pathways remain unknown. This study aimed to characterize the prevalence and regrowth of NTM in building water supply system in a hospital where many M.

Ciprofloxacin (CIP) and oxytetracycline (OTC) are commonly detected antibiotic species in breeding wastewater, and microalgae-based antibiotic treatment technology is an environmentally friendly and cost-effective method for its removal. This study evaluated the effects of CIP and OTC on Scenedesmus sp. in the breeding wastewater tailwater and the removal mechanisms of antibiotics.
