Uses of lime for the benefit of the environment
Grupo Calidras actively involved in environmental protection by safeguarding the elements of nature. Lime protects the air, water, and soil and is very safe to use due to its low toxicity; it is a naturally sourced product with applications for resolving problems related to environmental contamination.
Grupo Calidra products solve various pollution problems and allow for the remediation of potential environmental damage.
LIME IS USED FOR:
· Water potabilization by removing silica, sulfates, fluorides, or heavy metals, and reducing nutrients like phosphates and nitrogen.
· Sewage treatment municipal and industrial.
· Water conditioning for thermoelectric plants, boilers, and industrial processes.
· Use for irrigation.
· Neutralization of acid rain.
· Sludge Stabilization.
· Adjusting the pH of lakes and lagoons.
· Functions as a filter in rivers and streams.
EFFECTS ON WATER TREATED WITH LIME
· Reduces or eliminates bad odors.
· Clarifies the water by removing suspended solids.
· Disinfects the water from viruses and bacteria.
· Aids in the elimination of fats and oils.
· Controls the proliferation of algae and water hyacinths.
· Promotes the development of fish in aquifers.
EFFECTS ON SEWAGE SLUDGE TREATED WITH LIME
· Elimination of bad odors.
· Reliable bacterial control, eliminating harmful fauna such as insects and larvae.
· Improved workability.
· Reduction of moisture.
· Improves the utilization of industrial equipment.
ADVANTAGES OF WATER TREATMENT WITH CALIDRA LIMES
Calidra lime removes silica, sulfates, phosphates, hardness, and heavy metals, transforming river or reservoir water into potable water. It reduces bad odors and decreases bacteria, yeasts, and viruses in sewage sludge, and, to top it all off, it aids in softening, flocculation, and neutralization.
REMINERALIZATION OF DESALINATED WATER WITH LIME
· Adjusts the pH in desalinated water.
· Lime provides calcium, which remineralizes desalinated water.
· Neutralizes acidic water produced by desalination processes.
Air
Most of the fossil fuels used on the planet, with the exception of clean energies, release a high sulfur content, which causes acid rain. Acid rain affects aquatic and terrestrial ecosystems, damaging forests, acidifying lakes, rivers, and aquifers, and depleting soils. Additionally, it contaminates the air we breathe, creating short- and medium-term health problems if left untreated.
EFFECTS ON GASES TREATED WITH LIME
· Removes sulfur and nitrogen from combustion gases.
· Neutralizes greenhouse gases.
· Prevents combustion gases from reaching the atmosphere.
ADVANTAGES OF GAS TREATMENT WITH CALIDRA LIMES
· They help neutralize all greenhouse gases.
·
By preventing combustion gases from reaching the atmosphere, they minimize irremediable damage to the environment.
· They decrease the production of gases that generate acid rain, global warming, and the increase in illnesses and health risks.
Soil
The soil is the most superficial layer of the Earth's crust, making it one of the most important natural resources that must be protected.
Lime is essential in the preparation of land for sanitary landfills, as it prevents soil contamination, the proliferation of harmful organisms, and foul odors.
In the treatment of solid waste, lime plays an extremely important role. When mixed with the waste, it converts them into less harmful substances, as lime prevents leachates that often damage the soil and water tables, which is ultimately beneficial for the environment
SOLID WASTE TREATMENT
Municipal Landfill Waste Management:
· Allows for better compaction.
· Due to its alkaline properties, it controls the development of pests and harmful fauna.
Industrial Waste Disposal:
· Efficient neutralization of acidity.
· Forms stable compounds with heavy metals, preventing their migration or leaching.
· Protects water tables.
REMEDIATION OF PETROLEUM-CONTAMINATED LAND
· Lime contributes alongside other chemical products to the recovery of fertile soil contaminated by oil spills.
· Lime reacts with the silicates and aluminas in the soil to encapsulate the oil chains, allowing for the development of plants and crops.
INDUSTRIAL WASTE IN MINES
· Prevents contamination in tailings deposits.
· Avoids the migration or leaching of heavy metals by rainwater.
· Forms a chemical barrier that protects the subsoil.
· Prevents dust pollution from wind erosion by forming a stabilized, impermeable layer.
SLUDGE STABILIZATION
· Elimination of bad odors.
· Reliable bacterial control.
· Moisture reduction.
· Improved workability.
·
Generates the possibility of obtaining soil for agricultural use.
ADVANTAGES OF SOIL TREATMENT WITH CALIDRA LIMES
· Neutralizes acids.
· It is easy and safe to handle and dose as a reagent.
· Very low toxicity.
· Regenerates acidic soils, making them fertile.
· In waste incineration, it captures toxic particles like mercury and acidic greenhouse gases, preventing them from reaching the environment.
· Works as a neutralizing agent in forest soils.
COMPOST PRODUCTION
· Provides calcium as an essential nutrient element for plants.
· Facilitates the decomposition of organic matter.
· Controls unpleasant odors.
·
Due to its high alkalinity, it controls insects.
