Activated carbon is used to prevent DBP formation, remove contaminants of emerging concern, and improve water’s taste and smell. Activated carbon also protects water treatment plants against chemical spills into source waters. Activated carbon and UV oxidation systems remove groundwater VOCs. UV systems provide disinfection, and with the addition of hydrogen peroxide, can address taste and odor issues. Ion exchange technologies can be used to remove inorganic contaminants.
Slot Injector System Expands Capacity At Landfill Leachate Treatment Facility By KLa Systems
A landfill had an existing single basin SBR plant to process the leachate which is notable for its high nitrogen load. The original system was installed with a fine pore diffuser aeration system and due to the chemical/biological composition of the mixed liquor it was prone to diffuser fouling and premature membrane failure. During the design phase it was decided to use a more robust aeration system. The KLa Systems Slot Injector Aeration System was selected due to its superior aeration efficiency in complex wastewaters, flexible design features, and its proven long term, trouble free operation.
Durability For A Dollar By The Gorman-Rupp Company
Hopkins, MN, occupies four square miles of space in south-central Minnesota and is home to 17,000 residents. Originally a housing location for employees of the Minneapolis Threshing Machine Company, Hopkins is now better known as the raspberry capital of America — a distinction that can be traced back to some of the early families that inhabited the area and grew them.
Two-Way AMI System Fully Automates Meter Reading-To-Billing Process By Mueller Water Products
Chillicothe Municipal Utilities (CMU) was in the process of replacing more than 4,000 outdated water and electric meters when it determined that the project also presented an ideal opportunity to implement a systemwide advanced metering infrastructure (AMI) network.
Hybrid Blowers Save Money, Energy By Aerzen
Best known as the home of outdoor retailer L.L. Bean, the community of Freeport is a popular summer destination on the shore of Casco Bay in southern coastal Maine. In 2010, the Freeport Sewer District brought in Freeport-based engineering firm Woodard & Curran to conduct an energy analysis of the Freeport Wastewater Treatment Facility. The assessment revealed that the Freeport plant consumed more than 8.9 kBtu per gallon of wastewater treated, more than double the national average of 4.1 kBtu per gallon.

Scale deposit, corrosion, and biological proliferation can cause system downtime, loss of equipment efficiency, and increased risk of disease from pathogenic micro-organisms. The Hydrex range offers two advanced series of high-performance chemical formulations for the treatment of open and closed cooling systems.
Based on your specifications, and using Recoflo proprietary technology, Eco-Tec offers water treatment systems that can be composed of micro media filters, demineralizers, reverse osmosis, and condensate polishers.
Moisture and airborne dust, oil, dirt, and other contaminants can damage sensitive electronic equipment, and sealed enclosures that protect these electronics are prone to overheating. The Compact Cabinet Cooler is an air-to-air heat exchanger that solves these problems by cooling and recirculating the clean air inside the cabinet.
Caught between a withering drought and floods from winter storms, California faces the worst of both worlds—dealing with scarcity as well as stormwater. America, and much of the world, is watching to see how this trendsetting state handles those challenges.
