Mixing and Matching

This month we’ve got some takeaways from chemical dosing case studies in the municipal water and wastewater fields, we identify three keys to getting the best in hydraulic and mechanical polymer activation, and finish off by dropping into the tech and spec of submersible chemical induction high rate mixers.  

February, of course, also means Valentines Day. We think that’s as good of a time as any to give a shout out and express appreciation to all of our customers, manufacturers, contractors, colleagues, and friends. At CPC Co., our long-standing success is a direct result of the connections we forge and the relationships we maintain. We couldn’t do it without you.

To that end, we’d also like to remind you to email  sales@cpcrowley.com if you’d be interested in our 30-minute snapshot presentation to keep you and your organization up to date with our product line.   

Now on to the Chatter . . .

Manufacturer of the Month

PULSAFEEDER has a long history of manufacturing products to get the job done, delivering the chemicals into water and processes around the world. Among Pulsafeeder’s many outstanding products are the Eclipse® line of gear pumps for chemical dosing.

Combining proven design principles with patented features, Eclipse sealless gear pumps are safe, simple, and reliable. Structurally rugged with corrosion resistant materials, these rotary pumps are an ideal fit for many corrosive liquids, covering the entire pH scale.

Designed for simplicity and renewable performance, the innovative technology behind Eclipse supports its ability to handle the most corrosive chemicals with a simple-to-service, front pull-out design.

In numerous municipal water and wastewater case studies, Eclipse pumps have repeatedly demonstrated themselves to be ideal solutions for tackling very real and significant challenges.

In one case study, the water facility’s existing peristaltic pumps were creating excessive pulsations in the chemical dosing discharge, causing system upsets, and disrupting the disinfection process. The resulting amount of hose breakage and leakage was very much a concern as well. That facility’s upgrade to Eclipse pumps resolved these issues, in part due to the linear flow characteristics and ability to handle gaseous fluids without binding. Furthermore, Eclipse’s feature a leak-free construction to ensure the safety of operators and plant personnel.

In multiple wastewater case studies, Eclipse pumps effectively handled a multitude of problems associated with both Sodium Hypochlorite and Sodium Bisulfite. In these instances, Eclipse’s non-metallic construction proved to be more than capable of handling all of the customer’s chemicals.

The Eclipse series is just one of the many top quality pumps that makes Pulsafeeder the recognized leader in fluid handling technology, including hydraulic actuated, mechanical, and solenoid diaphragm pumps, rotary gear pumps, centrifugal and peristaltic chemical metering pumps.

Top Three

UGSI CHEMICAL FEED is widely recognized for offering the most comprehensive line of both hydraulic and mechanical polymer activation methods.

Polyblend® mechanical polymer feeders, along with Dynablend™ and Dynajet™ hydraulic polymer feeders, are both proven technologies, having been in use in the field for decades, allowing UGSI to boast over 10,000 successful installations and clearly establishing them as the leader in polymer activation and blending.

Key features include:

  1. Two stage mixing with the highest energy applied first at the moment of initial wetting (MOIW) followed by a “quiescent” zone allowing more gentle activation as polymer science dictates.

  2. Extended residence time in the “quiescent” zone to optimize the continued charge site exposure as the polymer is activated in an optimal manner.

  3. Options for control, pneumatic conveyance (dry polymer), economic mix tank design and secondary dilution to fit any site condition and application challenge

Simply stated, UGSI Chemical Feed solutions are designed to optimize polymer performance because they follow the latest in polymer science.

The Cutting Edge

THE MASTRRR COMPANY is committed to making a world of difference in chemical feed technology. Among their variety of chemical induction high rate mixing systems, the Gas Mastrrr submersible series is designed to induct and flash mix gas and/or liquid chemicals with superior velocity gradient mixing intensity.

SERIES 32 is designed for vacuum inducting and flash mixing gas and/or liquid chemicals into open channels or basins. Units are available in ranges from 1/2 to 25HP for feed rates up to 10,000 PPD gas and 60 GPM liquid chemical per unit. The mixer utilizes a UHMW Polyethylene rotating distributor to disperse the chemical mix in a 360 degree radial discharge pattern.

SERIES 32PT is designed for non-vacuum flash mixing of liquid chemicals into open channels or basins. Units are available in ranges from 2 to 25 HP for feed rates of up to 60 GPM liquid chemical. The mixer utilizes an unobstructed rotating Hasteloy-C propeller to disperse the chemical mix in an axial discharge pattern.

SERIES 32XP is designed for non-vacuum flash mixing of Sodium Hypochlorite, Chlorine solution, Sodium Bisulfite, or other chemicals into open channels or basins. Units are available in ranges from 3 to 25HP and are supplied with X-Proof motors for CSO or SSO basins requiring Class 1, Division 1 rated motors.
