Hydrochlorothiazide Removal From Water

Hydrochlorothiazide (HCTZ) is a commonly used medication belonging to the class of drugs known as thiazide diuretics. It is primarily prescribed to treat high blood pressure and edema..

While HCTZ has proven effective in medical treatment, its presence in water sources can pose a significant concern due to potential environmental and health risks.

This article aims to provide manufacturing professionals with insights into the methods and technologies available for removing hydrochlorothiazide from water sources, emphasizing the importance of minimizing its environmental impact.

Hydrochlorothiazide Removal From Water

Hydrochlorothiazide can be removed through traditional methods such as Ozone or activated carbon however, each method has it’s limitation. For a cost effect and eco-friendly solution, our Nyex Rosalox technology stands out as the most effective system to effectively remove Hydrochlorothiazide (HCTZ) from water. By implementing technologies like the Nyex Rosalox system, we can reduce the presence of HCTZ and other endocrine disruptors in the environment, safeguarding aquatic ecosystems and human health.

Our Nyex Rosalox technology can succesfully treat hydrochlorothiazide down to below 0.03 µg/L.

How it works

What is hydrochlorothiazide used for?

Hydrochlorothiazide (HCTZ) is a widely prescribed medication classified as a thiazide diuretic. It is commonly used in the medical field to treat conditions such as high blood pressure (hypertension) and edema (fluid retention). By increasing urine production and reducing the amount of water and salt retained in the body, HCTZ helps lower blood pressure and alleviate swelling caused by various medical conditions.

HCTZ works by inhibiting the reabsorption of sodium and chloride ions in the kidneys, which leads to increased urine output and a decrease in blood volume. As a result, blood vessels can relax, reducing the pressure exerted on their walls and effectively lowering pressure.

Hydrochlorothiazide in the aquatic environment

Hydrochlorothiazide contamination in water bodies can have both short-term and long-term effects on aquatic life and ecosystems. Studies have shown that the drug can be persistent in the environment, remaining active in water for extended periods.

This persistence, coupled with its potential to bioaccumulate in organisms, raises concerns about the potential impact on aquatic life and the overall ecosystem.

Research has indicated that hydrochlorothiazide exposure can disrupt the endocrine systems of fish, affecting their reproduction and development. Furthermore, the environmental impact of hydrochlorothiazide in water sources can contribute to AMR (antimicrobial resistance), further exacerbating the challenges of treating infections in the future.

Hydrochlorothiazide removal methods

Several methods are employed to remove hydrochlorothiazide from water, each with its own advantages and limitations. One popular method is reverse osmosis for removing hydrochlorothiazide from water. Reverse osmosis (RO) utilizes a semipermeable membrane to remove impurities and contaminants.

RO has proven reasonably effective in removing a wide range of pharmaceuticals, including Hydrochlorothiazide. However, it can be energy-intensive and wastewater may require additional treatment steps to ensure complete removal.

Another method involves adsorption, which utilizes materials like activated carbon and granular activated carbon for hydrochlorothiazide removal These techniques trap and remove contaminants from water. Activated carbon possesses a high surface area and strong adsorption properties, making it an effective option for hydrochlorothiazide removal.

Does ozone remove hydrochlorothiazide?

Oxidation techniques including ozonation, have gained attention as a potential method for removing hydrochlorothiazide from water.
Ozone treatment can effectively break down the drug’s molecular structure, rendering it inactive and removing it from the water.

However, ozone treatment can be costly, energy-intensive and may require additional steps for complete removal, such as activated carbon filtration.

Furthermore, the use of ozone may generate potentially harmful by-products, requiring proper handling and disposal methods.

Does adsorption remove hydrochlorothiazide from water?

Adsorption for hydrochlorothiazide removal, particularly using activated carbon and granular activated carbon (GAC) have proven successful in removing this compound from water.

Activated carbon possesses a high affinity for pharmaceutical compounds, effectively trapping them on its surface. This method is relatively simple to implement and has a high removal efficiency.

However, the spent carbon resulting from the adsorption process requires appropriate management due to its potential environmental impact. The regeneration or disposal of spent carbon should be conducted in accordance with established regulations and best practices.
