Al Shamal is the capital city of the municipality of Madinat ash Shamal in Qatar. With the majority of the town's population not yet connected to a sewer network, there was an immediate need to provide a wastewater treatment plant to treat wastewater generated from the towns' population and small industries. Ashghal, the Public Works Authority of Qatar and its end user, decided to install a tanker discharge facility with a compact sewage treatment plant to produce effluent suitable for reuse in irrigation.
In 2016 Hillsborough County Public Utilities, a forward thinking organization, initiated the first direct potable reuse pilot project in Florida. In its efforts to utilize 100 percent of its reclaimed water, the progressive utility created a successful program to effectively suspend surface water discharges. The pilot project validated direct potable reuse, which is now a key initiative for many central Florida utilities due to the implementation of the Central Florida Water Initiative requiring the additional utilization of reuse water resources.
The Honouliuli Water Recycling Facility (WRF) includes filtration and UV disinfection to treat to Class R-1 reuse standards for various uses, including irrigation.

Calgon Carbon’s ion exchange technology is designed to remove dissolved ionic compounds from water or other liquids. Calgon Carbon offers media, fixed bed and continuous systems for a variety of applications.
In the adsorption process, contaminants break their bond with the water molecules and chemically adhere to a filter media. This is typically accomplished by directing the water flow through pressure vessels containing the filter media at a rate that allows enough contact time for adsorption to occur. AdEdge Water Technologies’ Bayoxide E33 adsorption media is the industry standard for arsenic removal. This granular ferric oxide media reduces up to 99% total arsenic, including both Arsenic (III) and Arsenic (V).
Simple And Economical Solids Separation
The simplicity of the SHS and SHP Sidehill Screens make them an excellent choice static screening applications. With no motors or moving parts the Sidehill Screens let gravity do the work as effluent flows down the screening media. The screening elements are fixed, curved, slotted, wedgewire screens oriented horizontally across the direction of flow. The screening surface is positioned at a steeply sloped angle providing an effective means of quickly stripping of liquid and allowing the solids to slide off the bottom of the screen.
What’s the best way to fight odors in the wastewater industry? Add a little oxygen. Adding Praxair’s pure oxygen to your existing process can raise the level of dissolved oxygen enough to reduce odors without further action. Even better, the use of a Praxair oxygen acetates treatment system will lower costs and help you meet your environmental goals. Our systems help you manage peak demand and increase capacity while reducing Volatile Organic Compound (VOC) emissions.

Self-Cleaning Wedgewire Screen
The RSS Externally Fed Drum Screen is a reliable self-cleaning screen for both municipal wastewater operations as well as many industrial applications. This screening technology performs particularly well in wastewater with high oil or grease loadings as well as scum applications that can blind other types of screens.
Ultraviolet (UV) irradiation is used for multifunctional purposes. UV is most commonly used as an environmentally friendly alternative to chemical disinfection. It’s one of the most effective methods for inactivating harmful pathogens such as Listeria, E.coli, Giardia and chlorine tolerant pathogens like Cryptosporidium. UV is also used for removal of organic and inorganic contaminants, including chlorine, ozone and Total Organic Carbon (TOC). UV used in conjunction with an Advanced Oxidation Process (AOP) will remove Compounds of Emerging Concerns (CEC's), Synthetic Organics (SO's), Endocrine Disruptor Compounds (EDC's) and Personal and Pharmaceutical Care Products (PPCP's), as well as various taste and odor compounds from water.
Off-the-shelf solutions just won’t cut it. You want consistent, custom, world-class service that is both affordable and uncompromising. Each year, hundreds of chemical, food, oil and pharmaceutical manufacturers, municipalities, remediation contractors, government agencies and many others turn to Calgon Carbon for their service needs.
