The compression ratio of the micropump as one of the critical performance indicator is defined as the ratio between the stroke volume, i.e. fluid volume displaced by the pump membrane over the course of the pump cycle, and the dead volume, i.e. the minimum fluid volume remaining in the pump chamber in pumping mode.
Pollution prevention (P2) is a strategy for reducing the amount of waste created and released into the environment, particularly by industrial facilities, agriculture, or consumers. Many large corporations view P2 as a method of improving the efficiency and profitability of production processes through waste reduction and technology ...
However, there were several pollution enforcement cases in the 1960s and 1970s where the law was cited for broader pollution control objectives, prior to passage of the 1972 Clean Water Act. [ 13 ] By the mid-20th century, water pollution laws in the United States began to include health- and use-based standards to protect environmental and ...
The United States Congress has enacted federal statutes intended to address pollution control and remediation, including for example the Clean Air Act (air pollution), the Clean Water Act (water pollution), and the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA, or Superfund) (contaminated site cleanup).
Operators must use the BAT to control pollution from their industrial activities to prevent, and where that is not practicable, to reduce to acceptable levels, pollution to air, land and water from industrial activities. The Best Available Techniques also aim to balance the cost to the operator against benefits to the environment.
New Source Performance Standards (NSPS) are pollution control standards issued by the United States Environmental Protection Agency (EPA). The term is used in the Clean Air Act Extension of 1970 (CAA) to refer to air pollution emission standards, and in the Clean Water Act (CWA) referring to standards for water pollution discharges of industrial wastewater to surface waters.
Air-source heat pumps take heat from the air and use a refrigerant that circulates it between an indoor fan coil unit and an outdoor compressor to expel the cold air and pipe in the hot air. By ...
The Pollution Prevention Act focused industry, government, and public attention on reducing the amount of pollution through cost-effective changes in production, operation, and raw materials use. Opportunities for source reduction are often not realized because many existing environmental regulations focus on waste treatment and disposal ...
