The Ultimate FAQ Guide for Cooling Tower Water Treatment

Water is unquestionably the most utilized component in industrial cooling processes. This is mainly driven by its relatively affordable costs, availability, and tolerance to high heat levels. However, cooling towers reliant on the water often necessitate cooling tower water treatment systems to elevate the quality of cooling tower feed water.

This mitigates the growth and accumulation of organics on the cooling system as well as scaling and corrosion, which will most likely decrease the performance levels and efficiency of the system. To help you understand cooling tower filtration better, our article today answers the web’s most asked questions related to processes and machinery.

➣What is Cooling Tower Water Treatment?

Cooling tower sand filter system refers to the water treatment process employed to extract damaging pollutants from water used in cooling towers.

Typically, cooling tower water treatment seeks to elevate the quality of cooling tower feed water, blowdown water, and circulation water. To augment the efficiency of cooling tower water treatment processes, we have developed specialized cooling tower water treatment equipment. These high-end systems can treat varying types of feed water and consequently generate high-quality cooling tower water.

Primarily, technologies such as ultrafiltration, media filtration, and ion exchange are employed in cooling tower water treatment. The processes regulate the iron levels, hardness levels, alkalinity, TDS, and TSS levels in your cooling tower water. NEWater manufactures premium cooling tower water treatment systems feasible with distinct cooling towers including closed-circuit cooling towers and open-circuit cooling towers.

➣How Does Cooling Tower Water Treatment Work?

Distinct water treatment processes can be employed in cooling tower water treatment. The choice of the ideal processes is primarily determined by the feed water characterization and the type of cooling tower. Nonetheless, ordinary cooling tower sand filter system plants adhere to the following treatment stages.

● Intake of makeup water.

Makeup water refers to the water that substitutes the leaked, bleeding, or evaporated water from the cooling system. Ordinarily, makeup water is sourced from conventional water sources like municipal tap water, groundwater, or treated effluent. The makeup water may necessitate treatment to extract hardness minerals and silica or to regulate its alkalinity.

● Filtration.

After the makeup water intake, the cooling tower water is then filtered to eradicate suspended solids and remove turbidity and organic elements. The filtration process is mainly carried out using media filtration systems like cooling tower sand filters or membrane filtration systems like ultrafiltration systems. The extraction of suspended matter is essential as it helps avert membrane and ion exchange resin fouling in the latter stages.

● Ion exchange treatment.

This process is employed when your feedwater exhibits intolerable levels of hardness. Cation exchange resins are specifically used to extract the hardness minerals i.e. calcium and magnesium. They accomplish this by swapping the Ca2+ and Mg2+ ions with sodium (Na+) or potassium (K+) ions. This process protects your cooling tower against scale buildup and corrosion.

● Chemical treatment.

Consequently, appropriate chemical reagents are injected into the water to neutralize acidity and curtail the growth of biofilms and microbes. The commonly used chemical reagents include corrosion inhibitors like bicarbonates, which regulate acidity, scale inhibitors, like phosphoric acid, which mitigate the accumulation of scale, and algaecides like bromine, which inhibit the flourishing of microbes.

● Side-stream filtration.

Side-stream filtration primarily utilizes multimedia filters to extract objectionable pollutants in systems where the cooling tower water is recirculated. These contaminants are likely to find their way into the cooling tower water through leaks or drift contamination.

● Blowdown treatment.

Blowdown treatment seeks to recover or recycle used cooling tower water using advanced technologies like reverse osmosis and water deionization. The alienated pollutants are discarded in compliance with discharge regulations, while the recovered water is reused in the cooling tower. Underneath is a tutorial explaining how cooling tower filtration works.

➣Which Types of Cooling Tower Filter Systems Do You Provide?

Cooling tower water treatment systems are sets of equipment used to eliminate fouling contaminants from water meant for cooling towers. We are renowned manufacturers of industrial water treatment systems with an extensive catalog of cooling tower water systems. Beneath are some of our most coveted cooling tower sand filter systems.

● Cooling tower sand filters.

Cooling tower sand filters are media filtration systems made up of distinct layers of sand, which trap suspended solids and remove turbidity in feed water for cooling towers. We manufacture cooling tower sand filters with varying flow rates, production capacities, and designs to accommodate distinct scales of industries.

● Multimedia filters.

In cooling tower water treatment, multimedia filters are commonly used in the side-stream filtration stage. They are characteristically composed of three or more layers of filtration media i.e. garnet, sand, and anthracite. This allows them to filter out finer constituents hence they are considered more efficient and productive than traditional sand filters.

● Ultrafiltration systems.

Ultrafiltration systems are membrane filtration systems driven by pressure to separate suspended solids and other pollutants from water. The primary filtration medium in ultrafiltration systems is semipermeable membranes with pore sizes measuring approximately 0.005–0.1 µm.

In recent years, ultrafiltration systems have overtaken media filtration systems as the preferred equipment for extracting suspended matter from water thanks to their unrivaled rejection rates and efficiency.

● Ion exchange systems.

Ion exchange water treatment systems technically eliminate dissolved ionic pollutants from water by replacing them with desirable ions. In cooling tower water treatment, they extract hardness-causing minerals, volatile metals, and chemicals. To soften cooling tower water, cation exchange resin filters charged with sodium or potassium ions are used. We manufacture

• Two-bed ion exchange systems.
• Mixed-bed ion exchange systems.

● Reverse osmosis systems.

Reverse osmosis systems are water treatment systems that extract Total Dissolved Solids (TDS) from water using partially porous membranes. They are reliant on pressure and are often used in the blowdown treatment of cooling water. Our cooling tower RO systems can expel up to 99.7% of dissolved solids from raw water. They also extract microbes, dissolved ions, organic compounds, and chemicals from feed water.

➣What Are the Chief Benefits of Cooling Tower Water Treatment?

Cooling tower filter system is generally a low-cost and low-risk process employed to prolong the lifespan of cooling towers and uphold their optimal performance levels. The technologies and systems currently in use are cutting-edge hence cooling tower water treatment has proliferated. The following are additional rewards of cooling tower water treatment.

➣Why Do I Need a Cooling Tower Water Treatment System?

If your industry is reliant on cooling towers, you definitely need a cooling tower filter to prevent untimely fouling. Cooling tower water treatment systems remove objectionable impurities from cooling tower feed water thereby mitigating organic growth, corrosion, and scale buildup. As such, your cooling tower continues to perform at optimal levels with minimal or zero interruptions.

In addition, they reduce the frequency of maintenance as well as the manpower needed to maintain the cooling tower. An elaborate cooling tower water system also minimizes the number of chemicals needed to treat cooling tower water. This makes cooling tower sand filter systems quite efficient in resources used and costs.

Ultimately, a cooling tower water treatment system prolongs the life expectancy of your cooling system thereby guaranteeing quick returns on investment.
