Deutsch: Wasser / Español: Agua / Português: Água / Français: Eau / Italiano: Acqua
Water is a liquid at normal temperatures but exists also solid (ice), and water vapor (cloud) in the air.
A water molecule has the formula H2O which means that two hydrogen (H) atoms and one oxygen (O) are connected.
Deutsch: Wasserschutz / Español: Conservación del agua / Português: Conservação da água / Français: Conservation de l’eau / Italiano: Conservazione dell’acqua
Water conservation in the environment context refers to the efficient management, protection, and sustainable use of freshwater resources to prevent depletion and ensure long-term availability for ecosystems, agriculture, industry, and human consumption.
Water filters are the substances (such as charcoal) or fine membrane structures used to remove impurities from water.
Deutsch: Wasserfiltration / Español: Filtración de agua / Português: Filtração de água / Français: Filtration de l'eau / Italiano: Filtrazione dell'acqua
Water filtration is the process of removing impurities, contaminants, and suspended particles from water to make it safe for drinking, industrial use, or environmental discharge. In the environmental context, water filtration is a critical component of water management that helps protect human health, preserve ecosystems, and ensure sustainable water resources. Filtration can involve physical, chemical, or biological methods to treat water from various sources, including rivers, lakes, groundwater, and wastewater.
Deutsch: Wasserverschmutzung / Español: Contaminación del agua / Português: Poluição da água / Français: Pollution de l'eau / Italiano: Inquinamento idrico
The degradation of aquatic ecosystems due to Water Pollution poses one of the most pressing environmental challenges of the 21st century. It arises when harmful substances—ranging from industrial chemicals to agricultural runoff—enter water bodies, altering their physical, chemical, or biological properties. This phenomenon not only threatens biodiversity but also compromises human health, food security, and economic stability.
Deutsch: Wasserreinigung / Español: Purificación del agua / Português: Purificação da água / Français: Purification de l’eau / Italiano: Purificazione dell’acqua
Water purification refers to the process of removing contaminants, pollutants, and harmful microorganisms from water to make it safe for drinking, industrial use, and environmental sustainability. It involves physical, chemical, and biological methods to improve water quality and protect public health and ecosystems.
Water quality is a term used to describe the chemical, physical, and biological characteristics of water, usually in respect to its suitability for a particular purpose.
Deutsch: Wasserqualitätsmanagement / Español: Gestión de la calidad del agua / Português: Gestão da qualidade da água / Français: Gestion de la qualité de l'eau / Italiano: Gestione della qualità dell'acqua
Water quality management refers to the practices, policies, and strategies used to maintain or improve the quality of water in rivers, lakes, groundwater, and oceans. In the environmental context, it focuses on ensuring that water resources are clean, safe, and sustainable for ecosystems and human use. Effective water quality management is essential to prevent pollution, safeguard public health, and support biodiversity by addressing contamination from industrial waste, agricultural runoff, urban development, and other human activities.
Deutsch: Wasserqualitätsüberwachung / Español: Monitoreo de la calidad del agua / Português: Monitoramento da qualidade da água / Français: Surveillance de la qualité de l’eau / Italiano: Monitoraggio della qualità dell’acqua
In the environmental context, water quality monitoring refers to the continuous or periodic testing and analysis of water sources to assess their physical, chemical, and biological characteristics. The goal is to determine whether water is safe for human consumption, agriculture, industry, and ecological health.
