A septic drain field, a septic tank, and associated piping compose a septic system. The drain field typically consists of an arrangement of trenches containing perforated pipes and porous material (often gravel) covered by a layer of soil to prevent animals (and surface runoff) from reaching the wastewater distributed within those trenches.

Unlike the traditional septic system, the aerobic treatment system produces a high quality secondary effluent, which can be sterilized and used for surface irrigation. This allows much greater flexibility in the placement of the leach field, as well as cutting the required size of the leach field by as much as half. [1]
This is calculated as the total volumetric capacity of the leach tank/s divided by the volumetric throughput of the solid/liquid slurry. Retention time is commonly measured in hours for precious metals recovery. A sequence of leach tanks is referred to as a leach "train", and retention time is measured considering the total volume of the leach ...
Mound systems are an alternative to the traditional rural septic system drain field. They are used in areas where septic systems are prone to failure from extremely permeable or impermeable soils, soil with the shallow cover over porous bedrock, and terrain that features a high water table.
A good example of the autoclave leach process can also be found in the metallurgy of zinc. It is best described by the following chemical reaction: [citation needed] 2 ZnS + O 2 + 2 H 2 SO 4 → 2 ZnSO 4 + 2 H 2 O + 2 S. This reaction proceeds at temperatures above the boiling point of water, thus creating a vapour pressure inside the vessel.

Iowa State never trailed, shot 49 percent (24 of 49) from the field and 47.6 percent (10 of 21) from 3-point range. Baylor shot 29.7 percent (19 of 64) overall and 24.1 percent (7 of 29) from ...
In-situ leach works by artificially dissolving minerals occurring naturally in the solid state. The process initially involves the drilling of boreholes into the ore deposit. Explosive or hydraulic fracturing can be used to create open pathways in the deposit for the solution to penetrate. Leaching solution is pumped into the deposit where it ...
