The degradation rate describes the rate at which organic or inorganic substances in water or wastewater are degraded by physical, chemical or biological processes. In industrial water and wastewater treatment, the degradation rate is an important parameter for evaluating the efficiency of purification processes, particularly with regard to the
The evaporation residue refers to the solid and dissolved residues that remain after the evaporation of water or wastewater. These residues consist of non-volatile components such as salts, minerals, organic substances and other impurities that do not escape with the water vapor during the evaporation process and therefore remain concentrated in the residual liquid.
Filterable substances are solid particles and suspended solids that are contained in water or wastewater and can be retained by mechanical filtration processes. These substances include a wide range of particles such as sand, sludge, organic substances, fats, oils and inorganic solids. The parameter of filterable substances is a central
Discharge refers to the controlled removal of water or wastewater from a system, be it a natural body of water, a drainage system or an industrial water treatment or wastewater treatment plant. In technical systems, the discharge is a decisive parameter for the management of water and wastewater volumes, as it determines both the hydraulic
Deposits are solid substances that deposit on the surfaces of pipes, heat exchangers, tanks or other water-bearing systems. These solids are formed by the precipitation of dissolved substances that crystallize or solidify as a result of chemical, physical or biological processes. In industrial water and wastewater treatment, deposits are a common problem.
The discharge values are important parameters that describe the quality of the treated wastewater that leaves a water or wastewater treatment plant and is discharged into natural waters or the sewage system. These values determine the limit values of pollutants and contaminants that may still be contained in the wastewater after treatment in order to
A separator is a technical device used in water and wastewater treatment to remove unwanted substances such as solids, grease, oils, heavy metals or suspended solids from liquids. Separators are used to increase the efficiency of subsequent treatment processes, to protect systems from blockages or damage and to minimize the
A sedimentation tank is a technical device for the mechanical pre-treatment of water or wastewater in which solids are separated from the water by sedimentation. The basin uses gravity to separate suspended solids and thus reduce the solids content in the water or wastewater. Sedimentation tanks are used in industrial water treatment
The settling velocity describes the speed at which particles in a liquid sink by gravity. It is a decisive parameter in sedimentation tanks and clarification processes, where solids are separated from the water by sedimentation. The settling velocity varies depending on the density and size of the particles. In practice, the
Absorption is a physico-chemical process in which gases, liquids or dissolved substances are absorbed into another medium and evenly distributed there. In industrial water and wastewater treatment, absorption primarily refers to the absorption of pollutants, gases or organic compounds into a liquid or solid medium.
