Maximizing Water Treatment Efficiency with the CAL~FLO Lime Slurry and Liquid Calcium Hydroxide Feed System

In the realm of water or wastewater treatment, the significance of lime and lime-based solutions cannot be overstated. As the world faces increasing challenges related to water quality, it becomes imperative to explore innovative and efficient methods for water treatment. This blog post delves into the intricacies of lime slurry and its pivotal role in water treatment, highlighting the groundbreaking patents of Burnett Lime Company, such as the RE~MIN PROCESS® (U.S. Patent Nos. 8,951,491 B2, 9,751,784 B2) and the CAL~FLO® System (U.S. Patent Nos. 6,572,259).

Understanding Lime Slurry:

Lime slurry is a versatile solution derived from lime, a naturally occurring mineral. Lime has different common names, from milk of lime to hydrated lime slurry. Lime itself can be found in various forms, including quicklime and hydrated lime. Quicklime is the result of heating limestone, while hydrated lime is produced by adding water to quicklime. In water treatment, lime slurry is a popular choice due to its ability to address a myriad of issues, ranging from acidity to sludge stabilization. The use of lime can vary from household use on lawns with liquid calcium carbonate, liquid calcium hydroxide solution for drinking water treatment or wastewater treatment, or a slaked lime, or quicklime slurry for construction of roads, stabilization of soil, or flue gas desulfurization. Regardless of the application, slurry is a suspension in general, and different grades are used for different applications, from treatment plants to power plants.

The RE~MIN PROCESS® and Its Impact, more than just a calcium hydroxide feed system:

At the forefront of lime-based innovations is Burnett Lime Company's REMIN PROCESS®. This patented technology (U.S. Patent Nos. 8,951,491 B2, 9,751,784 B2) revolutionizes the utilization of lime in water treatment. The REMIN PROCESS® optimizes the efficiency of lime and its relationship with carbon dioxide gas, enhancing its reactivity and overall performance, creating an inline calcium bicarbonate to balance water. The ratios of water, CO2 gas, and lime are all critical to 'dial-in' the optimum pH and alkalinity for water treatment systems.

One key aspect of this process is the creation of air grade classified hydrate, a finely classified form of hydrated lime. The fine particle size and increased surface area of this hydrate result in superior suspension properties. This is particularly crucial in the treatment of wastewater, where efficient suspension of calcium hydroxide is necessary for various processes, such as softening and stabilization.

The use of lime slurry in the RE~MIN PROCESS® offers unparalleled benefits. The suspended particles ensure uniform distribution throughout the water, leading to enhanced alkalinity and stability. This is instrumental in neutralizing acidic components, thereby improving the overall quality of the treated water.

CAL~FLO® System: Setting Standards in Water Treatment Processes:

Another notable innovation from Burnett Lime Company is the CAL~FLO® System, protected by U.S. Patent Nos. 6,572,259. This system streamlines the use of lime slurry in water treatment applications, providing a reliable and efficient solution for diverse challenges.

The CAL~FLO® System is designed to handle lime slurry with precision, offering advantages such as controlled dosing and minimized wastage. Its implementation ensures optimal utilization of lime, leading to cost-effectiveness and reduced environmental impact. The patented system also addresses concerns related to scaling, a common issue in water treatment processes.

SULFA~PRESS®: Specialty Lime Products for Odor Control:

In the pursuit of comprehensive Odor Control and wastewater treatment solutions, Burnett Lime Company introduces SULFA~PRESS®, an specialized alkali lime solution for use in wastewater and collection systems. This particular blend of lime, or suspension of calcium hydroxide is used to tie up Hydrogen Sulfide gas until the wastewater stream reaches the treatment plant for wastewater treatment.

SULFA~PRESS® is a testament to Burnett Lime Company's dedication to addressing specific challenges in water treatment, particularly in the context of sulfide removal. This trademarked solution showcases the company's ability to innovate and develop targeted approaches to water treatment issues.

Keywords in Lime Slurry Applications used in Water Treatment Processes:

In exploring lime slurry for water treatment, it is crucial to understand its diverse applications. Lime slurry, derived from calcium carbonate, plays a pivotal role in treating both drinking water and wastewater. The solid particles in lime slurry, when properly suspended, prove effective in various processes, from neutralization to sludge dewatering.

The use of lime in water treatment is not limited to its chemical composition but also involves the deployment of specialized equipment. Pumps, silos, and pneumatic systems are integral components in the efficient handling and application of lime slurry. These equipment ensure precise dosing, uniform distribution, and effective utilization of lime in different treatment stages. Burnett Lime was clearly aware of the failures of many of the traditional silos, pumps, and feedlines, so back in 1992 they developed the first patented CAL~FLO System, guaranteeing clog-free lines and sediment free tanks. After 40 years in business, they are still growing strong.

Particle Size and Surface Area, Hint: It's more than quick lime or lime water:

Particle size and surface area are critical factors in the efficacy of lime slurry. The RE~MIN PROCESS® emphasizes the importance of fine particle size and increased surface area in creating air grade classified hydrate. This characteristic enhances the suspension of calcium hydroxide in water, facilitating better interaction with impurities and contaminants. Poorly cooked CaO, or Calcium Oxide, for lime slaking can cause turbidity issues in water plants, that is why slurry preparation of the CAL~FLO Slurry is different. Solubility in water is critical, and with the low solubility of calcium, it is critical to make sure you deal with the expert in Lime: Burnett Lime Company. 

Effluent Quality and Lime Slurry, produce better sludge, remove contaminants, extend pump life:

Effluent quality is a paramount concern in water treatment, and lime slurry emerges as a valuable tool in achieving desired outcomes. The suspension of calcium hydroxide, enabled by innovations like the RE~MIN PROCESS®, contributes to efficient stabilization and alkalinity adjustment. As a result, effluent quality is significantly improved, meeting stringent standards and ensuring environmental compliance.

Conclusion:

In the dynamic landscape of water treatment, lime slurry proves to be an indispensable solution, with the innovations of Burnett Lime Company standing out prominently. The REMIN PROCESS® and CALFLO® System, along with the trademarked SULFA~PRESS®, showcase the company's commitment to advancing water treatment technologies.

As industries and communities continue to grapple with water quality challenges, the utilization of lime slurry, guided by innovative patents and trademarks, becomes a cornerstone in achieving sustainable and efficient water treatment solutions. The multifaceted applications, from softening to stabilization, underscore Burnett's versatility and its crucial role in addressing the ever-evolving complexities of water treatment processes.
