Brining on the other hand, uses osmosis via a combination of salt and water , to develop flavor and moisture. As an experiment, take two slices of eggplant, and liberally salt one but not the other. Let them sit on separate plates for 10 minutes. That water is drawn out by the salt. Well, the answer is it does, but that ok because of…. Osmosis, is a process where water moves and out of cells.
And because salt draws water, we can use it to actually move water in and out of food. Without getting into the gory details, the salt in a brine, given enough time, will carry moisture and potentially flavor into whatever is being brined.
Most brines also contain sugar, to balance out the salt, and bring some additional flavor the party. You can also add many other flavors, like peppercorn, or other spices, herbs, or other flavoring liquids. Unlike marinades, you need to brine for a long time I never do less than 8 hours. Short periods will draw moisture out of food, without giving time for it to be pulled back in.
I generally use brines for low fat cuts of meat. Swelling soils will retain their natural structure, but soil structure will be lost once dispersion occurs. This loss of structure impedes the ability of water to infiltrate and move through the soil, increasing the potential for erosion.
Table 1. This is due to an osmotic effect, which causes water to move from areas of low salt concentrations, in the roots, to areas of high salt concentrations, in the soil. Due to the impacts of high salt concentrations on soil and vegetation, impacted sites suffer from a decline in plant growth. This is magnified by the inability of many seeds to germinate. Under these conditions, seeds have difficulty taking up water, causing damage to the embryo or dormancy in response to water stress. Plants exposed to brine often die due to salt stress resulting from the inability to take up water and key nutrients.
Most plants will show signs of salt stress if sodium exceeds 70 milligrams per liter in water, 5 percent in plant tissue or milligrams per liter in soil saturated paste extract. Chloride negatively impacts most plants when it exceeds milligrams per liter in water, 1 percent in plant tissue or milligrams per liter in soil saturated paste extract.
However, some plant species are salt-tolerant; they are called halophytes. Table 2. John The goal of brine spill remediation is to remove or minimize salts in the soil, allowing for improved vegetation growth and establishment. Remediation can be accomplished through ex situ or in situ methods.
Ex situ methods are most often utilized in North Dakota. During ex situ remediation, the topsoil or impacted depth is excavated from the site and moved to a landfill that is approved for the containment of oil-field wastes.
New topsoil is brought in to replace the removed soil. The new topsoil may have different chemical and physical properties, including a different seedbank, than the original soils. The new soil will not be contaminated with brine, but it should be managed to maintain a clean, weed-free seedbed for the reclamation process.
Figure 6. The topsoil was removed from this spill site as part of ex situ remediation. In situ methods remove the salts from the topsoil while keeping the soil in place. For example, solutions with a high concentration of salt are known to reduce thermal conductivity, so brine waste is often recycled and reused as a cooling agent for steel heat exchangers in many power plants.
This type of brine is often treated to remove dissolved oxygen and other harmful contaminants since brine waste can be highly corrosive to plant machinery and piping if untreated , and the presence of dissolved oxygen and other contaminants can increase that risk.
Varying salt concentrations in the brine stream will also determine how the temperature, pressure, and other threshold limitations will need to be adjusted during production , so facilities that use brine as part of their process often run frequent tests to ensure the relevant purification requirements are consistently met.
Below, we break down a general overview of the various brine waste treatment and disposal options available and what they mean for your facility:. As mentioned earlier in the article, many industrial processes require brine in part of their process, such as hydrometallurgy , sodium hypochlorite , lithium carbonate, and chlor-alkali manufacturing plants, to name a few.
Some facilities even use leftover brine for irrigation or deicing. Google Analytics -The Google Analytics cookies are used to gather anonymous information about how you use our websites.
