|April 9, 2010
Summary
Ozone decontamination is more effective for swimming pool water than chlorine, preventing irritating chloramines. Redox potential monitoring enhances safety checks for both methods.
Area of Science:
- Environmental Science
- Water Treatment Technologies
- Public Health
Context:
- Swimming pool water quality is crucial for public health.
- Traditional chlorine disinfection can lead to undesirable byproducts.
- Existing regulations may lack comprehensive monitoring for advanced disinfection methods.
Purpose:
- To compare the efficacy of ozone and chlorine for swimming pool water decontamination.
- To investigate the interaction of oxidants with ammonia impurities.
- To evaluate the utility of redox potential measurement for real-time monitoring.
Summary:
- Ozone treatment demonstrated superior effectiveness in decontaminating swimming pool water compared to chlorine.
- Ozone effectively prevents the formation of irritating chloramines, a common issue with chlorine.
- Redox potential measurement provides a valuable tool for monitoring decontamination efficiency, particularly for ozonation.
Impact:
- Ozone offers a safer and more effective alternative for swimming pool disinfection.
- Improved water quality reduces potential health risks and enhances swimmer comfort.
- Enhanced monitoring protocols can ensure consistent and reliable water treatment outcomes.

Quality of Water
In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...
Testing Water Quality
When the quality of water for concrete preparation is uncertain, its impact on the setting time of cement and compressive strength of mortar is assessed by comparison with de-ionized or distilled water benchmarks. American Society for Testing and Materials (ASTM) C1602 requires the setting times to be within 90 minutes of the control, British Standard (BS) 3146:1980 allows a 30-minute variance in the initial setting, while British Standards European Norm (BS EN) 1008 specifies initial setting...
Deleterious Substances in Aggregate
Deleterious substances in aggregates can be detrimental to the quality and durability of concrete. These substances include organic impurities like loam, which interfere with cement hydration and are usually present in the sand. These prevent a good bond between aggregate and cement paste. Organic impurities can be detected using the colorimetric test, where the darkness of a solution after agitation indicates the level of organic content.

Waterproofing and Anti-Bacterial Admixtures in Concrete
Concrete's susceptibility to water absorption is due to the capillary action within the pores of its hydrated cement paste. This action draws water in, creating the need for waterproofing admixtures to prevent such penetration. The efficacy of these admixtures is contingent upon the water pressure, with variations arising from different conditions such as rain, capillary rise, or hydrostatic pressure in structures intended to hold water.

Coagulation
Colloidal solids are solid particles suspended in solution. They are usually negatively charged, attracting a compact primary layer of positively charged ions, which attract more counterions to form an electrical double layer. Electrostatic repulsion between the charged double layers prevents the particles from colliding, stabilizing the colloids. These solids are often undesirable because they can contain toxins that are difficult to remove. Coagulation is a technique that helps aggregate and...
Biological Treatment of Effluent and Waste Water
Biological wastewater treatment relies on the metabolic activity of microorganisms to remove pollutants from sewage. In modern treatment systems, this process is organized into sequential stages that progressively reduce solid material, dissolved organic matter, and microbial contamination. Each stage plays a distinct role in improving water quality and preparing the effluent for safe discharge or reuse.Primary and Secondary TreatmentPrimary treatment is a physical process that removes large...
