  • Pros And Cons Of Wastewater Treatment Methods Coagulation & Disinfection

    Every stage in a wastewater treatment process is important to achieve the desired treatment results. However, primary treatment and tertiary are critical to the overall process. In the primary treatment process solids are reduced to a large extent. Without this step, subesequent treatment would be less effective. In tertiary treatment, harmful microbiological matter is rendered killed or inactive so that it will not cause sickness to those organism that encounter it.

  • Pros And Cons Of The Advanced Oxidation Process

    In many water and wastewater treatment applications, there are a number of pollutants that are difficult to reduce by physical, chemical, or biological means alone. In more recent years, there has been a growing concern regarding pharmaceutical drugs in drinking water and aquatic environments. Pesticides get caught in runoff from farms into freshwater supplies. Personal care products are typically washed down the drain into whatever system they are linked to. Landfill leachate is a toxic cocktail of compounds that can leak into groundwater sources. Such contaminants fall into the category of micropollutants, because they are so small. Their size alone is part of the reason, they are so difficult to remove from water and wastewater by certain means. More efficient removal requires a more powerful oxidation process, this process is called an advanced oxidation process (AOP).

  • 5 Top Advantages MBBR Wastewater Treatment

    Wastewater treatment solutions have become one of the significant moves to filter waste water. Whether it is for fighting with the growing shortage of drinking water or finding better water sources for wastewater, several technologies have been practice for centuries, and MBBR wastewater treatment is being used for filtering waste water in both industrial and domestic sectors.

  • Using ATP And NGS To Monitor Nitrification

    China Steel Corporation, a steel producer in Taiwan, produces wastewater that is high in organics, ammonia, solids, and other waste products. The wastewater is treated on-site using a series of biological treatment processes. The variable influent quality can make it challenging to meet treatment objectives.

  • The Highly Consolidated U.S. UV Water Treatment Equipment Market

    The U.S. ultraviolet water (UV) water treatment equipment market for industrial and drinking water applications is competitive, mature, and saturated. The market is dominated by a few leading players holding significant market shares.

  • Common UV Lamps For Chemical-Free Disinfection

    When it comes to water and wastewater treatment systems, operational and performance variation will come from different components, including what treatment processes are deployed, whether chemicals are utilized, or how much power the treatment processes require. With many treatment systems, there is much consideration given to a particular central component akin to the heart and soul of the process. In the case of a UV system, the ultraviolet (UV) lamps are this component.

In the primary treatment process, solids are reduced to a large extent. Without this step, subsequent treatment would be less effective. In tertiary treatment, harmful microbiological matter is rendered killed or inactive so that it will not cause sickness to those organisms that encounter it.

  • Xylem Helps South Carolina Utility Eliminate Taste And Odor Issues In Drinking Water

    Advanced oxidation treatment system and water treatment plant upgrade save money.

  • UV Treatment System Fills The Bill For Water Reuse

    Small city selects full-featured and low maintenance UV treatment for its water reuse system that easily complies with demanding California Title 22 Regulations.

  • How To Choose A UV System For Water Reuse In Your Facility

    Water reuse is, and will continue to be, one of the biggest considerations for companies all over the world in the battle against water scarcity. By reusing process water, grey water, and wastewater, buildings and facilities will reduce their demand for raw water from surface and groundwater sources and reduce the associated costs of supplying raw water and treating raw water before use. One of the treatment methods for accomplishing this is UV disinfection.

Municipalities are tasked every day to ensure that wastewater is treated effectively and appropriately, using the best available technology. Disinfection is the final, critical step in the treatment process.

ABOUT WASTEWATER DISINFECTION

 

Wastewater disinfection takes place after primary, secondary and sometimes tertiary wastewater treatment. It is typically a final step to remove organisms from the treated water before the effluent is released back into the water system. Disinfection prevents the spread of waterborne diseases by reducing microbes and bacterial numbers to a regulated level.

A variety of physical and chemical methods are used to disinfect wastewater prior to it being released into natural waterways. Historically, the chemical agent of choice for municipal wastewater treatment has been chlorine, due to its disinfecting properties and low cost. However, the rising cost of chlorine and concerns that low chlorine concentrations can still be toxic to fish and other wildlife, has given rise to more physical methods of wastewater disinfection being adopted such as ozonation or ultraviolet (UV) light.  

The use of ozone as a disinfection agent has the added benefit of increasing the dissolved oxygen content of the treated wastewater. However, because the ozone has to be generated, ozonation can require prohibitive up-front capital expenditure compared to traditional chlorination. UV disinfection has been growing in popularity as a wastewater disinfection method, in large part because of the life-cycle economics of the equipment and the fact that, like ozone, there is no toxic residual.
