Uses of lime that benefit the environment
Grupo Calidra is present in the protection of the environment, taking care of the elements of nature. Lime protects air, water, and soil; and is very safe to use due to its low toxicity. It is a product of natural origin with application for solving problems related to environmental pollution.
Grupo Calidra products solve different problems that generate pollution and allow irreparable damage to the environment to be reduced.
Water
Lime is used for water treatment, since it has a biocidal effect, this means that it has the ability to disinfect and eliminate existing bacteria or microorganisms. It also acts as a neutralizer, coagulant, clarifier, and precipitant of dissolved contaminants. At the same time, it facilitates the stabilization and removal of heavy metals.
In the treatment of waste sludge, lime has an indispensable role, since it dehydrates the sludge and raises the pH, this helps heavy metals to form stable compounds, acids are neutralized, and pathogenic elements are eliminated. It also controls infectious sources, as it prevents the putrefaction of organic matter and prevents unpleasant odors.
LIME IS USED FOR:
Water purification by removing silica, sulfates, fluorides, or heavy metals; and reducing nutrients such as phosphates, and nitrogen.
Sewage treatment municipal and industrial.
Water conditioning for thermoelectric plants, boilers.
Use for irrigation.
Neutralization of acid rain.
Sludge stabilization.
Adjusts the pH of lakes and ponds.
It works as a filter in rivers and streams.
ADVANTAGES OF WATER TREATMENT WITH CALIDRA LIMES
Calidra removes silica, sulfates, phosphates, hardness, and heavy metals, transforming river or dam water into drinkable water, reduces bad odors and reduces bacteria, yeasts and viruses in waste sludge, and if that is not enough, it helps in softening, flocculation, and neutralization.
EFFECTS IN WATER TREATED WITH LIME CAL
Reduces or eliminates bad odors.
Clarifies water by eliminating suspended solids.
Reduces the content of bacteria and viruses.
Helps in the elimination of fats and oils.
Controls the proliferation of algae and water lily.
Promotes the development of fish in aquifers.
EFFECTS ON WASTE SLUDGE TREATED WITH LIME
Elimination of bad odors.
Reliable bacterial control.
Better workability.
Humidity reduction.
Improves the utilization of industrial equipment.
REMINERALIZATION WITH LIME DESALINIZED WATER
Adjusts the pH in desalinated water.
Lime contributes calcium, so the desalinated waters are mineralized again.
It brings the acidic waters produced by desalination processes to a neutral point.
Soil
Soil is the most superficial layer of the Earth, so it is one of the most important natural resources that must be taken care of.
Lime is essential in the preparation of land for landfills, since it prevents soil contamination as well as the proliferation of harmful organisms and foul odors.
In the treatment of solid waste, lime plays an extremely important role. When mixed, these become less harmful substances, since lime neutralizes acid currents and adjusts the pH, which is less aggressive for the environment.
SOLID WASTE TREATMENT
Garbage Management in Municipal Landfills:
Allows better compaction.
Facilitates the decomposition of organic matter.
With its high alkalinity it controls the development of vectors such as insects or rodents.
Industrial Waste Deposit:
Efficient neutralization of acidity.
It keeps heavy metals fixed, preventing them from being carried away or leached.
Protects water tables.
INDUSTRIAL WASTE IN MINES
Avoid contamination during on-site storage.
Prevents the dragging or leaching of heavy metals with rainwater.
Forms a chemical barrier and protects the subsoil.
Prevents dust pollution through the action of the wind, forming a stabilized layer with clay materials.
COMPOST PRODUCTION
Provides calcium as an essential nutritional element for plants.
Facilitates the decomposition of organic matter.
Controls unpleasant odors.
Due to its high alkalinity, it controls insects.
REMEDIATION OF LAND CONTAMINATED WITH OIL
Lime contributes with other chemicals in the recovery of fertile soil that was contaminated by oil spills.
Lime reacts with silicates and alumina in the soil to encapsulate oil chains and allow the development of plants and crops.
SLUDGE STABILIZATION
Reliable bacterial control.
Elimination of bad odors.
Humidity reduction.
Better workability.
It generates the possibility of obtaining land for agricultural use.
ADVANTAGES OF SOIL TREATMENT WITH CALIDRA LIME
Neutralizes acids.
It is easy and safe to handle and dose as a reagent. Very low toxicity.
Muy baja toxicidad.
Counteracts the effects of acid rain.
In waste incineration, it captures toxic particles such as mercury, acidic greenhouse gases, and prevents them from reaching the environment.
It works as a neutralizer in forest soils.
Air
When burning flammable materials, they generate acid gases and particles that affect the air in the atmosphere and the environment. The use of lime for the control of toxic gases is very important, given that by raising the pH in industrial processes the formation of said gases is avoided, which represents a benefit to the environment.
Most of the fuels that pollute our planet have a high sulfur and nitrogen content, producing greenhouse gases such as carbon monoxide and carbon dioxide, sulfur oxides, and nitrogen oxides. The presence of these elements causes serious complications in the environment.
EFFECTS ON GASES TREATED WITH LIME
Cleaning of contaminated gases.
Neutralizes greenhouse gases.
Prevents combustion gases from reaching the atmosphere.
ADVANTAGES OF GAS TREATMENT WITH CALIDRA LIME
They help neutralize all greenhouse gases.
By preventing combustion gases from reaching the atmosphere, irreparable damage to the environment is minimized.
They reduce the production of gases that generate acid rain, global warming, increased diseases, and health risks.
