Bahrain has a universal health care system, dating back to 1960. [1] Government-provided health care is free to Bahraini citizens and subsidized for non-Bahrainis. Healthcare expenditure accounted for 4.5% of Bahrain's GDP, according to the World Health Organization. Bahraini physicians and nurses form a majority of the country's workforce in ...
Rainwater management is a series of countermeasures to reduce runoff volume and improve water quality by replicating the natural hydrology and water balance of a site, with consideration of rainwater harvesting, urban flood management and rainwater runoff pollution control. The continuous growth of human populations and the consequent growing ...
Septic drain fields, also called leach fields or leach drains, are subsurface wastewater disposal facilities used to remove contaminants and impurities from the liquid that emerges after anaerobic digestion in a septic tank. Organic materials in the liquid are catabolized by a microbial ecosystem . A septic drain field, a septic tank, and ...
Radburn design housing (also called Radburn housing, Radburn design, Radburn principle, or Radburn concept) is a concept for planned housing estates, based upon a design that was originally used in the community of Radburn within Fair Lawn, New Jersey, United States .
A grinder pump (also called a macerator pump) is a wastewater conveyance device. Waste from water-using household appliances ( toilets, bathtubs, washing machines, etc.) flows through the home’s pipes into the grinder pump’s holding tank. Once the wastewater inside the tank reaches a specific level, the pump will turn on, grind the waste ...
Enhanced biological phosphorus removal (EBPR) is a sewage treatment configuration applied to activated sludge systems for the removal of phosphate. [1] The common element in EBPR implementations is the presence of an anaerobic tank ( nitrate and oxygen are absent) prior to the aeration tank. Under these conditions a group of heterotrophic ...
Aerobic treatment system. An aerobic treatment system ( ATS ), often called an aerobic septic system, is a small scale sewage treatment system similar to a septic tank system, but which uses an aerobic process for digestion rather than just the anaerobic process used in septic systems. These systems are commonly found in rural areas where ...
Upflow anaerobic sludge blanket ( UASB) technology, normally referred to as UASB reactor, is a form of anaerobic digester that is used for wastewater treatment . The UASB reactor is a methanogenic (methane-producing) digester that evolved from the anaerobic clarigester. A similar but variant technology to UASB is the expanded granular sludge ...
