Filtration
The process of allowing water to pass through layers of a porous material such as sand, gravel or charcoal to trap solid particles.
Filtration: The mechanical process which removes particulate matter by separating water from solid material, usually by passing it through sand.
Filtration: A mechanical process which involves moving water through a material, usually sand, designed to catch and remove particles.
Filtration
A treatment process, under the control of qualified operators, for removing solid (particulate) matter from water by means of porous media such as sand or a man-made filter; often used to remove particles that contain pathogens.
FILTRATION: A process that separates small particles from water by using a porous barrier to trap the particles and allowing the water through.
filtration A process for removing suspended particulate matter from water by passage through a porous medium or media.
final order The last order, issued by the court in a lawsuit, that terminates the action.
Filtration Separation of a solid and a liquid by using a porous substance that only lets the liquid pass through.
filtration. A process for removing particulate matter from water by passage through porous media.
infiltration velocity
The actual rate at which water is entering the soil at a given time. It may be less than the maximum (the infiltration rate) because of a limited supply of water (rainfall or irrigation).
Infiltration
1. The penetration of water through the ground surface into sub-surface soil or the penetration of water from the soil into sewer or other pipes through defective joints, connections, or manhole walls. 2.
Infiltration rate: The quantity of water that enters the soil surface in a specified time interval. Often expressed in volume of water per unit of soil surface area per unit of time.
Infiltration: entry of water from precipitation, irrigation, or runoff into the soil profile.
Inorganic Chemicals: natural or synthetic chemicals that contain no carbon.
Insecticide: substance that kills insects.
Infiltration - Infiltration is the process of water entering the soil. Often of concern is the infiltration rate - the rate at which water enters soil.
Exfiltration: Air leakage outward through cracks and interstices and through ceilings, floors, and walls of a space or building.
Exhaust Air: Air removed from a space and not used therein.
Infiltration
The downward entry of water through the soil surface into the soil. Infiltration constitutes the sole source of water to sustain the growth of vegetation and it helps to sustain the ground water supply to wells, springs, and streams.
Microfiltration
the use of microporous filters operating under pressure to remove particles or microorganisms of 0-1-5-0 µm size from process and effluent liquids
Microorganisms ...
Microfiltration. A physical separation process where tiny, hollow straw-like membranes separate particles from water. It is used very effectively as a pre-treatment for reverse osmosis.
mg/L. Milligrams per liter.

Direct Filtration
A method of treating water that consists of the addition of coagulant chemicals, flash mixing, coagulation, minimal flocculation, and filtration. Sedimentation is not uses.

Water Infiltration: The process by which water enters building structures such as roofs, walls, floors and other building components through leaks in plumbing systems or natural occuring water from outside of the building.
Filtration: The filtering out of particles during the purification process for drinking water.
Food Web: A community of organisms that are dependent on one another for food.
Gradient: The slope of the streambed profile.
Filtration: A treatment process for removing solid (particulate) matter from water by passing the water through sand, activated carbon, or a man-made filter. The process is often used to drain and disperse wastewater.
Filtration
Removal of particles, normally solids, from a fluid. These can be contaminants or valuable products.
Financial Assurance for Closure ...
An infiltration practice designed to treat rooftop runoff. Runoff is directed to the trench via a downspout. It is temporarily stored in the voids of the trench, and then percolated into the ground.

glomerular filtration rate
Volume of ultrafiltrate formed in the kidney tubules from the blood passing through the glomerular capillaries divided by time of filtration.

infiltration. 1) The gradual flow or movement of water into and through (to percolate or pass through) the pores of the soil. Also see percolation. 2) the penetration of water from the soil into sewer or other pipes through defective joints, ...
Infiltration - the downward entry of water into the immediate surface of the soil, as contrasted with leaching (percolation),
which is the movement of water from the soil.
Irrigation - application of water to soils to assist in plant growth.
infiltration (soil) Movement of water from the ground surface into the soil. infrared radiation Electromagnetic radiation lying in the wavelength interval from 0.7 micrometers to 1000 micrometersm.
Typically can be reused for irrigation after being run through a filtration system. Back to top ^

Habitat The sum of the environmental conditions that determine the existence of a community in a specific place.
Infiltration occurs when the water seeps into the ground, The infiltration rate depends on the permeability of the ground.
First and foremost is filtration at the faucet. Carbon-based filters are considered the most effective at removing THMs and other toxins. The consumer information website WaterFilterRankings.
Recharge area: Area of land allowing water to pass through it into an aquifer by surface infiltration.
Soil moisture management for forest land generally consists of protecting the litter layer and organic matter so that forest lands maintain high rainfall infiltration and minimize soil erosion.
Indoor-air quality-control strategy to remove various airborne particulates and/or gases from the air. Most common methods are particulate filtration, electrostatic precipitation, and gas sorption.

Closure The act of preparing a landfill for long term inactivity, including placement of a cover over the landfill to prevent infiltration of surface water.
Coagulation Particle destabilization to enhance agglomeration.
Agglomeration - (Water Quality) The grouping of small suspended particles into larger particles that are more easily removed through filtration, skimming, or settling. Also see Coagulation.
Greywater - waste water that does not contain sewage or fecal contamination (such as from the shower) and can be reused for irrigation after filtration. Read more about greywater here.

Superinsulation involves substantially increased R-values combined with proper detailing for minimized thermal bridging and thorough air sealing for minimized infiltration.
Hydrological (water) cycle is he cycle of the earth's water supply from the atmosphere to the earth and back which includes precipitation, transpiration, evaporation, runoff, infiltration, and storage in water bodies and groundwater.
