Magnesium Chloride (MgCl₂) in Feed: Functions and Considerations 1. Magnesium Supplementation to Prevent Deficiency Physiological Role: Magnesium is essential for energy metabolism (e.g., ATPase activation), bone development, nerve signaling, and muscle contraction. Applications: Ruminants (cattle, sheep): Prevents "grass tetany" (hypomagnesemia), especially in regions with low magnesium in pasture. Poultry & Swine: Supports bone health, eggshell formation (poultry), and reproductive performance. Bioavailability: MgCl₂ has high bioavailability, ideal for rapid magnesium supplementation. 2. Feed Processing Improvement Anti-caking agent: Enhances feed flowability and prevents moisture-induced clumping. Binder: May improve pellet stability during feed processing. 3. Electrolyte Balance Maintenance Synergy with Na⁺/K⁺: Regulates acid-base balance and mitigates heat stress (e.g., in high-temperature environments). Aquatic feed: Supplies magnesium ions for crustaceans (shrimp, crabs) to support molting and exoskeleton hardening. 4. Additional Functions Digestive aid: Moderate Mg²⁺ stimulates intestinal motility and digestion. Salt substitute: Partially replaces NaCl in low-sodium feeds to adjust palatability. Precautions Dosage: Overuse may cause diarrhea (especially in monogastric animals). Ruminant feed typically requires 0.2%-0.4% magnesium. Palatability: High concentrations may impart bitterness; ensure uniform mixing. Regulations: Comply with local standards (e.g., China’s Feed Additive Safety Guidelines). Storage: MgCl₂ is hygroscopic; store sealed to prevent clumping. Comparison of Magnesium Sources Source Bioavailability Cost Features MgCl₂ High Moderate Hygroscopic; suitable for liquids MgO Low Low Slow-release; common for ruminants MgSO₄ High Moderate Provides sulfur; may cause diarrhea

Calcium Chloride in Petroleum Extraction

08 Mar,2025

Calcium chloride (CaCl₂) plays several key roles in oil drilling and extraction, explained in simple terms: 1. Adjusting Drilling Fluid Density Purpose: During drilling, drilling fluid (like a "lubricant + protective liquid") needs enough weight to prevent underground high-pressure oil or gas from suddenly erupting (a "blowout"). Mechanism: Dissolving calcium chloride in water increases the fluid’s density, similar to "adding salt to make water heavier." This heavier fluid counteracts underground pressure, ensuring safer drilling. 2. Preventing Wellbore Collapse Issue: When drilling through clay layers, regular water can soften the clay, causing the well walls to collapse like wet sand. Solution: Calcium ions in calcium chloride "harden" clay particles, acting like "glue" to stabilize the well walls. 3. Speeding Up Cement Curing Use: After drilling, cement is used to seal gaps between the well casing and the surrounding rock. Role: Adding calcium chloride to cement acts as a "fast-curing agent," accelerating hardening and reducing wait times. 4. Moisture Absorber (Desiccant) Scenario: Moisture in equipment or pipelines can cause corrosion or operational issues. Function: Calcium chloride’s strong hygroscopicity (like a "super-absorbent sponge") removes moisture, keeping systems dry. Simplified Summary: Calcium chloride is a versatile tool in oil extraction—acting as a "ballast" to prevent blowouts, a "hardener" to stabilize wells, a "cement accelerator," and a moisture fighter. Its diverse applications make it critical for safe and efficient operations.

The role of calcium chloride in water treatment

11 Feb,2025

Calcium chloride (CaCl ₂) has multiple functions in wastewater treatment, mainly based on its chemical properties and ionic characteristics. The following are its main applications and mechanisms of action: --- **1. Phosphorus removal function** -Principle: Calcium ions (Ca ² ⁺) react with phosphates (PO ₄³ ⁻) in wastewater to form insoluble calcium phosphate precipitates (Ca ∝ (PO ₄) ₂), thereby reducing the phosphorus content in water. -* * Application * *: Widely used for chemical phosphorus removal in industrial wastewater or domestic sewage, especially suitable for pretreatment of high phosphorus wastewater. --- **2. Coagulation and coagulation aid** -Charge Neutralization: Ca ² ⁺ neutralizes the negative charges on the surface of colloidal particles, promotes the aggregation of suspended solids and colloidal particles, and enhances the flocculation effect. -* * Synergistic effect * *: Often used in combination with other coagulants such as polyaluminum chloride and polyacrylamide to improve floc density and settling speed. --- **3. Adjust pH and alkalinity** -Neutralizing acidity: Calcium chloride aqueous solution is weakly acidic and can neutralize alkaline wastewater, adjusting the pH to a neutral range. -Supplementing Calcium Hardness: In softened water treatment, calcium ions are added to balance water hardness and prevent pipeline corrosion. --- **4. Sludge conditioning** -* * Dehydration performance improvement * *: Adding calcium chloride can change the colloidal structure of sludge, release bound water, and improve the dewatering efficiency of sludge (commonly used in plate and frame pressure filtration or centrifugal dewatering processes). -* * Inhibit Corruption * *: Calcium ions can inhibit some microbial activity and reduce odors during sludge storage. --- **5. Heavy metal removal** -* * Substitution reaction * *: Ca ² ⁺ can displace heavy metal ions (such as Pb ² ⁺, Cd ² ⁺) in wastewater, forming hydroxide or carbonate precipitates. -Co precipitation effect: When used in combination with sulfides or carbonates, it promotes the co precipitation of heavy metals. --- 6. Winter antifreeze and maintenance of fluidity** -Lowering the freezing point: In cold regions, calcium chloride can prevent water in treatment facilities from freezing, ensuring the normal operation of pipelines and aeration tanks. -* * Improve fluidity * *: Reduce the viscosity of sludge at low temperatures, making it easier to transport. **Precautions** -The impact of chloride ions: Excessive addition may lead to an increase in the concentration of chloride ions (Cl ⁻) in the effluent, which may corrode metal equipment or affect the ecology of the receiving water body. -Microbial inhibition: High concentrations of calcium ions may inhibit the activity of microorganisms in activated sludge, and the dosage needs to be controlled. -Cost and alternative solutions: Compared with aluminum sulfate, polyaluminum chloride, etc., calcium chloride has a lower cost, but the appropriate agent needs to be selected according to the water quality target. **Summary** Calcium chloride is a multifunctional agent in wastewater treatment, with functions such as phosphorus removal, coagulation, pH adjustment, and sludge conditioning. However, its application needs to be optimized based on water quality characteristics, treatment processes, and environmental requirements to avoid side effects.
