WASTEWATER DISINFECTION RESOURCES

  • The City of Belleville, Ontario was planning on re-developing downtown waterfront property into a public space containing a park and a green space. Unfortunately, the proposed site had a long history as an industrial site – initially for a coal gasification plant from 1854 to 1947 and then as a bulk oil storage facility from 1930 to 1990.

  • The Tri-Lakes Wastewater Treatment Facility located in Monument, CO, receives flow from the Woodmoor, Palmer Lake, and Monument Sanitation Districts. The plant discharges treated effluent to Monument Creek, which is within the Fountain Creek Water Shed. Originally, the Tri-Lakes facility consisted of a three-cell lagoon. This was replaced by a two-basin Biolac Wave-Ox system, which was installed in 1990 and later upgraded in 1998 to a three-basin system with a capacity of 4.2 MGD.

  • 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.

  • 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).

  • 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.

  • 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 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.

  • 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.

  • 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, 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.

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

WASTEWATER DISINFECTION SOLUTIONS

  • TrojanUVFit — Wastewater Disinfection System

    Depending on site and design conditions, wastewater treatment plants producing filtered effluent sometimes prefer a disinfection solution using in-pipe (also called closed-vessel) UV chambers. The TrojanUVFit® offers an effective, compact, and energy-efficient solution for non-potable reuse with a streamlined hydraulic profile that won’t break head in the treatment process. The system is available in multiple configurations to treat a wide range of flow rates, up to 7 MGD per chamber.

  • GENCLEAN-AQ

    GENCLEAN™ AQ is an NSG 60 certified specialized advanced oxidation treatment specially developed for process water disinfection and wastewater treatment for food & beverage processing companies and fish farms.

  • Foambuster

    The patented Foambuster uses the same glass-lined ductile iron nozzles as Rotamix but also uses a stainless steel splashplate located below the nozzle to deflect the nozzle discharge and create a broad spray of sludge, which wets and breaks up foam forming on the surface of the digester. Digester sludge is pumped through the Foambuster either by the Rotamix Chopper Pump or by a separate Chopper Pump. When the Foambuster is used in conjunction with a tank mixing system, which produces a rotational mixing pattern in the tank, only one spray nozzle will be required for effective foam control.

  • Control Of THMs With Chlorine Dioxide

    Chlorine dioxide (ClO2) is effective as both a disinfectant and an oxidant in water and wastewater treatment.

  • NeoTech D438™

    The NeoTech D438™ is specially designed to disinfect water and is an essential component in advanced oxidation processes.

WASTEWATER DISINFECTION VIDEOS

This presentation will look at the role that Ozone treatment plays addressing the evolving challenges of the water resources here in North America. During the presentation, we will review how ozone treatment is being used to address various drinking water challenges ranging from taste and odor to the contaminants of emerging concern.  We will also discuss the role that ozone plays in water reuse applications, providing multiple benefits in the reuse treatment train. Please join us as provide an overview of Ozone as a tool in meeting the complex challenges of today’s water and wastewater treatment requirements.

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.
