Fine Screen Retrofit Saves Hawaii's Largest Army Post $1M By JWC Environmental
To preserve Hawaii's natural beauty, keep up with growth, and ensure regulatory compliance, the U.S. Army Schofield Barracks, Hawaii's largest Army post, recently upgraded their wastewater treatment facility located on the island of Oahu. The result was improved efficiency, water quality, and decreased environmental impact on the region.
How Chemistry And Mechanics Deliver Cost-Effective Waste Treatment By IPEC
Polymer chemistry is one of the leading considerations when designing a sludge thickening system. The right polymer chemistry contributes to more effective thickening at a lower cost. However, the right chemistry must also be complemented by mechanical processes that enable the chemistry to work effectively. Waste treatment equipment manufacturer IPEC collaborated with polymer suppliers for extensive lab trials to design a waste-activated sludge (WAS) thickening system for the City of Brockville, a city of more than 23,000 people located in the southeastern part of Ontario, Canada. The rotary drum system is capable of thickening 5.25 I/second of 0.55 percent municipal sludge to up to 7 percent solids.
Hybrid Activated Sludge System Reduces Energy Consumption By 40% By Degremont Technologies
The HYBACS system utilizes an innovative nutrient-removal, hybrid activated-sludge process. The process consists of two biological stages: The first stage comprises SMART units with attached biomass; the second stage is an activated sludge process with suspended biomass.
Building Smart Water Networks By Sensus
A smart water network is an integrated set of products, solutions and systems that enable utilities to remotely and continuously monitor and diagnose problems, prioritize and manage maintenance issues, and use data to optimize all aspects of the water distribution network. Smart water networks can save utilities across the globe up to $12.5 billion a year according to research commissioned by Sensus.

The Great Graywater Debate
Widespread nonpotable reuse of graywater could potentially lead to a significant reduction in water demand, and over 8 million people across the U.S. are already using graywater for landscape irrigation. Yet most of the graywater reuse currently taking place is illegal.

The 910 COD Colorimeter is the newest addition to YSI’s line of colorimeters. This rugged, waterproof, single-parameter colorimeter for COD, in three different ranges, is ideal for laboratory and field testing.
Even small amounts of iron and manganese under regulated limits can cause discoloration, poor taste, foul odor, or deposit buildup, and therefore need treatment. Filtronics' Electromedia I removes iron and manganese to below detection limits (2 ppb) for high-influent concentrations of 8 to 10 mg/l or more.
The Water Specialties Propeller Meter is designed for measuring clean water flows in municipal and industrial applications with low maintenance and high durability. Meter materials and performance meet or exceed AWWA standard C704/92.
FILTRASORB 400 is a high-activity activated carbon used for water and wastewater treatment applications. This product is manufactured from select grades of bituminous coal, which is pulverized, reagglomerated with a suitable binder, activated, and screened to a 12 x 40 U.S. sieve particle size distribution.
