Disinfection

Disinfection is an essential component of water quality management because it helps to protect public health by reducing the risk of waterborne diseases. Water can contain harmful bacteria, viruses, and other pathogens that can cause illness or even death if consumed.

Disinfection is the process of killing or inactivating microorganisms. Disinfection is typically achieved through the use of chemical disinfectants, such as chlorine, chloramine, or ozone. Disinfection is especially critical in areas where the water source is surface water, such as lakes or rivers, as these sources can be more vulnerable to contamination.

Effective disinfection requires careful management and monitoring to ensure that the appropriate levels of disinfectant are present in the water supply. The goal is to provide protection against waterborne diseases while minimizing the risk of harmful byproducts or other adverse effects.

On-site hypochlorite generation (OSHG) systems for disinfection have seen an increased adoption rate in the last decade as water and wastewater utilities continue to grapple with the onerous complexity of risk management plans (RMPs) in the case of gas chlorine disinfection and the operational or cost challenges of using bulk 12.5% sodium hypochlorite for disinfection. The latest generation of OSHG systems have been designed to emphasize safety, reliability and maintainability.

Residual Management

Residual management is an essential aspect of water quality management. It refers to the process of maintaining a residual amount of disinfectant in drinking water to ensure that it remains safe to drink by killing harmful microorganisms that may be present in the water.

Disinfectants such as chlorine, chloramine, and ozone are commonly used to treat drinking water to eliminate harmful bacteria, viruses, and other pathogens. However, the disinfectant must remain in the water at a residual level to ensure that the water stays safe as it travels through pipes and storage tanks to reach consumers.

Disinfectant residual management involves monitoring the level of disinfectant in the water supply and adjusting the dosage as needed to maintain a residual amount. The goal is to ensure that the disinfectant is present at a level sufficient to provide protection against waterborne diseases, but not so high as to pose a health risk or affect the taste or odor of the water.

Effective disinfectant residual management requires a combination of regular monitoring, careful dosage adjustments, and proper maintenance of water treatment equipment.

THM Reduction

THM reduction is a process aimed at reducing the levels of trihalomethanes (THMs) in drinking water. THMs are a group of chemicals that are formed when chlorine or other disinfectants react with organic matter in the water, such as decaying plant material or animal waste. THMs are a suspected carcinogen and regulated in many countries. Exceeding the Maximum Contaminant Level (MCL) of THMs are among the most common violations of the EPA Stage II DBP rule in the United States.

Over the past ten years, water reservoir and/or water storage tank aeration have gained in popularity due to the relatively low capital costs, low operating costs and optional phased implementation of in-tank aeration systems. When combined with plant based solutions, tank oriented aeration systems allow utilities to actively manage THM formation in transmission and distribution on a system-wide basis.

At cleanwater1, we create a water treatment system within your tank using a custom-designed, energy-optimized combination of of mixers, aerators and ventilators.

Tank Mixing

Tank mixing can help improve water quality in several ways: Oxygenation, temperature control, nutrient distribution and sediment control.

Oxygenation. By mixing the water in a tank, oxygen is introduced to the water, which can help to increase dissolved oxygen levels. This is important for aquatic life, as they need oxygen to survive. Tank mixing can also help to prevent the buildup of harmful gases such as hydrogen sulfide and methane, which can be toxic to aquatic life.

Temperature control. Tank mixing can help to regulate the temperature of the water. In warm weather, mixing the water can help to prevent it from becoming too hot and causing thermal stress to aquatic life. In cold weather, mixing the water can help to prevent it from freezing over and creating a barrier to oxygen exchange.

Sediment control. Tank mixing can help to prevent sediment buildup in the tank, which can improve water quality.

Liquid Polymer Feed

Liquid polymer feed can improve water quality by removing suspended particles and impurities from water through a process known as flocculation.

When liquid polymer is added to water, it forms long chains of molecules known as polymers. These polymers attract and bind to small particles and impurities in the water, forming larger clusters known as flocs.

The flocs are then heavier and denser than the water, causing them to settle to the bottom of the water or float to the top, making it easier to remove them through sedimentation or filtration processes.

By removing these particles and impurities, liquid polymer feed can improve water clarity, reduce turbidity, and remove harmful contaminants such as bacteria, viruses, and heavy metals. This makes the water safer to drink and use for other purposes.

Dry Chemical Feed

Dry chemical feed is a method of adding chemical coagulants or flocculants to water for the purpose of removing suspended particles and impurities. Dry chemical feed involves adding a dry chemical powder to the water being treated.

The dry chemical is typically stored in bags or drums and is added to the water using a specialized feeder system. The feeder system can be manually operated or automated depending on the size and complexity of the water treatment system.

Dry chemical feed has some advantages over liquid polymer feed. For example, it can be more convenient to transport and store, and it can be easier to handle in smaller applications. However, dry chemical feed can be more difficult to handle and mix with the water which can result in lower treatment efficiency. It can also be more expensive in larger water treatment applications.

Overall, the choice between dry chemical feed and liquid polymer feed depends on the specific water treatment application and the characteristics of the water being treated. Both methods can be effective in removing impurities and improving water quality, but the selection of the most suitable method will depend on a range of factors such as cost, efficiency, ease of handling, and water treatment objectives.
