WASTEWATER DISINFECTION RESOURCES
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.
Pros And Cons Of Wastewater Treatment Methods: Coagulation And 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, 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.
Aging UV System Gets Replaced, New UV System Withstands Extreme Flooding Event (Case Study)
The city of Orange in Orange County, Texas, is located about 100 miles east of Houston, Texas, and approximately 30 miles due north of the Gulf of Mexico. It is the state’s easternmost city and home to the Orange Waste Water Treatment Plant (WWTP). Located along the Sabine River, this municipal wastewater treatment plant with a peak capacity of 24 MGD serves 18,000 residents and comprises of the following unit processes: bar screens, grit removal, primary treatment, trickling filter followed by sedimentation and finally, UV disinfection. The Sabine River is 510 miles long and in its lower course, empties into Sabine Lake, which is an estuary of the Gulf of Mexico.
Peracetic Acid: An Effective Wastewater Disinfectant
Peracetic acid (PAA) is one of the most versatile and widely used disinfectants on the market. PAA has proven to be an excellent sanitizer and disinfectant in the food, beverage, cosmetic, pharmaceutical, and agriculture industries for industrial water treatment, as well as an excellent disinfectant for use in the wastewater treatment industry.
Hypochlorite Bleaches Market Continues To Thrive On The Expanding Water Treatment Sector
An inherent vertical of the global specialty chemicals space, hypochlorite bleaches market has been observing remarkable popularity of late. With rising incidences of infectious illnesses on a global scale, the demand for disinfectants, bleaching, and sanitization products is likely to accelerate. Hypochlorite bleaches are popular disinfection products with the ability to terminate a vast array of disease-causing bacteria, fungi, viruses, and fungi, provided they are used with adequate precautionary measures and adhere to specific usage guidelines.
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.
