  2. Phosphatase - Wikipedia

    en.wikipedia.org/wiki/Phosphatase

    However, among well-studied phosphatase/kinase pairs, phosphatases exhibit greater variety than their kinase counterparts in both form and function; this may result from the lesser degree of conservation among phosphatases. [4] Calcineurin (PP2B) is a protein phosphatase enzyme involved in immune system function.

  3. Portable water purification - Wikipedia

    en.wikipedia.org/wiki/Portable_water_purification

    Instead of using the static pressure of a water supply line to force the water through the filter, pressure is provided by a hand-operated pump. These devices can generate drinkable water from seawater. The Portable Aqua Unit for Lifesaving (short PAUL) is a portable ultrafiltration-based membrane water filter for humanitarian aid. It allows ...

    Most organisms involved in water purification originate from the waste, wastewater or water stream itself or arrive as resting spore of some form from the atmosphere. In a very few cases, mostly associated with constructed wetlands , specific organisms are planted to maximise the efficiency of the process.

    The filter sand takes up most space of the chamber. It sits either on a nozzle floor or on top of a drainage system which allows the filtered water to exit. The pre-treated raw water enters the filter chamber on the top, flows through the filter medium and the effluent drains through the drainage system in the lower part.

  7. Bank filtration - Wikipedia

    en.wikipedia.org/wiki/Bank_filtration

    Chemical filtration or ion exchange may take place when aquifer soils react with soluble chemicals in the water. [3] Most 'normal' contaminants (microbial organisms and inorganic or organic pollutants) will be removed by bank filtration, either because they get filtered out by the sand/earth of the bank, or because the passage time (which may ...
