Mechanical process engineering
„ Mechanical engineering is a discipline of engineering that applies the principles of engineering, physics and materials science for analysis, design, manufacturing, and maintenance of mechanical systems. It is the branch of engineering that involves the production and usage of heat and mechanical power for the design, production, and operation of machines and tools….
Physical changes are changes affecting the form of a chemical substance, but not its chemical composition. Physical changes are used to separate mixtures into their component compounds, but can not usually be used to separate compounds into chemical elements or simpler compounds….
In general a physical change is reversible using physical means. ”

EnviCare® Engineering GmbH uses mechanical/physical methods in the field of wastewater treatment as well as in the field of air pollution control. For example, physical precipitants/flocculator devices are used for the pre-cleaning of industrial wastewater but also as a first step in the process of sludge dewatering.
Cyclones and compressed air pulse filters are widely used for dedusting of industrial air, but also in the form of a dry additive process for flue gas cleaning.
