The focus on effective grit removal is getting a lot more intense lately. Grit has become a hot topic. Last year, an all day Grit Workshop was held at WEFTEC. There were eight grit related papers presented including six addressing “A Focus on Grit Removal and Handling Strategies”. Of particular interest are settling characteristics and removal efficiencies of various technologies. The performance of historical, conventional mechanically induced vortex (MIV) units was questioned. The HeadCell was shown to outperform MIV systems. Contact us for a more detailed summary of this year’s papers.
We’d like to think the focus on grit has something to do with Hydro’s growing installation base of highly effective grit removal systems and satisfied customers throughout the United States. Right here in Kentucky, Indiana and Ohio are more than twenty Hydro grit removal systems in operation. Until now, most design engineers and plants did not have accurate reference data to use in effective grit system design, but they do now.. Hydro International now has available national and regional grit gradation data which is the result of more than 120 tests across North America. The data includes valuable average physical sizes as well as information on settling velocity (SES), making it the most comprehensive information available on grit and its behavior. We welcome the opportunity to share this valuable data with you. Contact us for specific gradation information. (Click here for gradation flyer)

A Product Spotlight – Hydro Vortex Drop™ Shaft
The Hydro Vortex Drop™ Shaft is a self-activating system with no moving parts that quietly and safely drops flow (water, stormwater or wastewater) from virtually any height. It offers improved flow characteristics, significant cost savings and better odor, corrosion and erosion control when compared to conventional drop systems.
Benefits
-No flow is too big or small
-Efficient Flow Control
-Erosion reduction
-Odor/Corrosion control
-Flexible design
-All stainless construction
The Hydro Vortex Drop™ Shaft can be retrofit into an existing chamber and its integrated access and small pipe sizes reduce excavation cost, shaft diameters and the need for a separate access shaft. The system also benefits from a compact and simple to construct inlet chamber with no complicated curves or benching required. With its unique operation and powerful mixing on the outlet of the system, the dissolution of gases into the liquid rather than releasing it into the chamber or atmosphere eliminates odors and corrosion problems based on high H2S concentrations.

Introducing the Cerlic O2X DUO submersible Dissolved Oxygen Sensor for continuous measurement of DO (with temperature output too—at no additional cost): made in robust 316SS!
The Cerlic O2X DUO submersible DO Sensor can use either an O2O Optical or Clark Cell. Your choice to meet your needs! The Cerlic Clark Cell uses a teflon membrane minimizing fouling with built in temperature compensation to provide stability. The Cerlic O2O Optical electrode uses Phase Shift Technology for a quicker response and improved stability as well as a new focusing lens for improved accuracy. A new cap coating is not damaged by UV light like other current optical electrode designs. Both types come with automatic in place cleaning using compressed air or water to ensure a long life. The electrodes are replaceable in the field. More on the Cerlic O2X DUO is here: Cerlic O2O.

HPT has two important announcements regarding Siemens.
On September 1, Siemens sold the General Filter brand to Westec. At the same time, Tonka Equipment Co. offered HPT their line. HPT elected to accept Tonka’s offer. Tonka has become a leader in the water industry in the last few decades with a broad offering of services and equipment for the water treatment industry. Tonka’s approach to the market matches up well with HPT in that Tonka offers process solutions, and helps our customers solve problems.
Last week, Siemens announced their plan to sell their Water Technologies business. Water Technologies includes leading industry brands of BioMag/CoMag, Davco, Davis Process, Envirex, Jet Tech, Memcor,RJE Odor Control, W&T Chlorinators, OSEC and Zimpro. It appears that the sale will close some time in the first or second quarter of 2013. We already know of several parties who have expressed an interest.
HPT has represented Envirex and most of the other brands for 20-30 years. During this time, there have been a number of corporate owners that preceded Siemens, notably, Banner Industries, NW Water, US Filter, Vivendi and Veolia. What has remained constant is HPT continues to assist engineers and owners with water and wastewater treatment solutions without disruption to our customers for 102 years. As we all go through more market turmoil, HPT will continue to offer the strongest and best products, even as Siemens divests itself of the Water Technologies unit. It is HPT’s goal to enable our customers to improve quality and reduce cost of their water treatment.
Toward this end, our values remain unchanged and we will:
-Operate safely
-Take care of the customer
-Achieve profitable growth
-Treat employees and competitors with respect
-Differentiate though innovation and unique solutions
-Define gaps and fill needs.
HPT is the oldest manufacturer’s representative in our business and offers solutions to each of our customer’s needs for water treatment. If you have any questions, please call us at 1-513-248-3200 or visit our website.
We are pleased to announce that HPT is the local representative for Tonka Equipment Company throughout Southern Ohio, Kentucky and Indiana. For over 55 years, Tonka has been providing custom water treatment systems including vertical & horizontal pressure filters, gravity filters, ion-exchange softening, and RO/NF/UF membrane systems. Tonka prides itself on timely, responsive customer service which matches the same level of service HPT has delivered since 1910.
There have been several changes that have occurred in the last several months in the water treatment industry. Mainstays of the industry have fallen victim of the recession with companies being sold and other companies going out of business. However, during these changes, HPT has maintained its strong presence in the marketplace by representing well respected companies that are leaders in the industry. Please give us a call to provide any service, whether that means answering questions for a new project or ordering parts for existing equipment. HPT looks forward to working with Tonka and to continue to provide great service to our clients.

Hydro International made an announcement at this year’s WEFTEC to expand their grit system capabilities. The GritCup™ and SpiraSnail™ grit washing and dewatering system are the latest additions to Hydro’s line of Advanced Grit Removal. The GritCup™ and SpiraSnail™ uses many of the best design features found in Hydro’s advanced grit removal systems. The free vortex washing in the GritCup™ provides highly effective grit washing reminiscent of the Eutek TeaCup® and SlurryCup™. The SpiraSnail™ clarifier design is based on the same hydraulic principles as the Eutek HeadCell® utilizing the conical shape to provide the surface area required to remove fine grit particles. The end result is a system that offers cost-effective automated grit washing and dewatering with no water requirement.
The GritCup™ and SpiraSnail™ are designed for plants with peak flows up to 10 mgd. The system is guaranteed to capture 90% of all grit 106 micron and larger with less than 20% volatile solids and greater than 60% total solids in output grit.

We are excited to share with you a new improved Aqua Guard screen and brush.
The UltraBrush™ is superior to the standard Aqua Guard® brush:
-Bridges have been added between the 4 rows of bristles
-Bristles are longer for greater penetration into the belt for better debris removal
The bridges double the effective circumference of the shaft making it harder for stringy items to wrap tightly around the core and inhibit small solids from adhering to the brush.
The brush design combined with the 3 times higher rpm (via a new brush drive motor) means the brush stays cleaner longer and is easier to clean and maintain.
Changing the brush has been made easier with the new Aqua Guard® Ultra Clean™. The brush is changed from the side of the machine instead of the rear. No more reaching into the rear of the screen to remove the brush. A video demonstrating the side-mount brush removal can be found by clicking here.
The UltraBrush™ can also be installed on most existing Aqua Guard® MN versions. These models come in a split core design, like the current brush, and are changed from the rear of the machine. Attached are brochures for the Aqua Guard® UltraClean™ Screen as well as an Aqua Guard® Rebuild.
If you are interested in Retrofitting or repairing your current Aqua Guard please contact Debbie Durchholz @
