Temperature-wise, this summer has been one for the record books. Things are also heating up right about now for baseball fans, with the pennant races in full swing. For our part, we’re bringing the heat via the August Chatter with a lineup of three outstanding manufacturers and their exceptional products.
To start, we’re tapping the inventor of the reverse-flow strainer, acknowledging the key role these strainers play in various stages of the wastewater treatment process, and identifying what truly sets them apart. For relief, a look at passive intakes and underdrain systems that represent the latest innovations in static intake screening equipment. To close, throw strikes by getting straight to the advantages thermoplastic pumps have over three other pump compositions.
Chatter up! . . .
Manufacturer of the Month
THE HELLAN STRAINER COMPANY was born in 1944, after Haakon Hellan, a Norwegian born inventor living in Cleveland, Ohio developed and patented a revolutionary “reverse flow” strainer. By collecting debris on the outside of the strainer element instead of inside, Hellan’s advancement changed the way strainers were made and employed. For the first time, an outside-to-inside flow allowed debris to be cleaned and flushed from the system without shutting down the flow or process.
Established with a vision to engineer advanced solutions that elevate industrial processes, The Hellan Strainer Company has grown and cemented itself as a global leader in the field of filtration technology. Armed with decades of experience and a team of dedicated experts, the company has consistently pushed the boundaries of possibility and performance, particularly in the realm of wastewater treatment.
Wastewater treatment demands precision, efficiency, and reliability. Contaminants, from debris to suspended solids, can disrupt the treatment process, potentially leading to equipment damage and environmental hazards. At their core, Hellan strainers are advanced filtration devices meticulously crafted to remove unwanted particles from water streams. The versatility of these strainers allows them to be seamlessly integrated into various stages of the treatment process, playing a vital role in maintaining the purity of water before it is released back into the environment.
- Robust Construction: Hellan strainers are engineered to withstand the demanding conditions of wastewater treatment plants. Their durable construction ensures longevity, reducing maintenance and replacement costs.
- Efficiency: With a high particle removal efficiency, Hellan strainers prevent clogging and blockages in downstream equipment, optimizing the entire treatment process.
- Customizability: The Hellan Strainer Company understands the unique needs of different wastewater treatment setups. Their strainers can be customized to fit specific plant requirements, making them a versatile solution.
- Reduced Environmental Impact: By effectively removing pollutants and contaminants, Hellan strainers contribute to the reduction of harmful substances discharged into natural water bodies, promoting environmental health.
- Operational Reliability: The use of Hellan strainers minimizes the risk of equipment downtime caused by debris accumulation, leading to uninterrupted treatment operations.
In 2018, Hellan acquired SSI Fabricated in Dayton, Ohio, bringing a full line of “traditional strainers” to their product offerings. These Wye, T, Duplex, and automated strainers are now a critical part of Hellan’s ability to be a one stop shop for all your strainer needs.
The Cutting Edge
JOHNSON SCREENS, a brand of Aqseptence Group, is the leading global provider of screening and auxiliary solutions. Their highly engineered and precisely fabricated products and solutions support various municipal applications and industries, including Water Wells, Environmental, Energy, Chemicals, Food and Beverage, Mining, and many more. Because of this, almost every product and object around you was touched by Johnson Screens.
As the original creators of the Vee-Wire® screens, Johnson’s innovative solutions incorporate 120 years of knowledge of the processes where they are used, and a tradition of excellent customer support.
Max-Flow™ Passive Intakes
With a history of 50+ years and over 4,000 installations, Johnson Screens Passive Intakes continue to lead the way in static intake screening equipment. The newest member of that family – the Max-FlowTM Passive Intake – was created with efficiency in mind. Fully 316b compliant, patented design of the Max-Flow evenly distributes flow and reduces the velocity to 0.5 feet per second or less. Its non-plugging design is easy to maintain using Johnson Screens’ patented Hydroburst screen cleaning system. With 1.4 times more capacity than the previous High-Capacity design, it offers significant capital savings in any intake project using fewer intake screens. The Max-Flow is available in all materials, including stainless steel, super duplex, and NSF-certified Z-Alloy.
Triton™ Underdrain System
The TritonTM Underdrain System offers the maximum surface area to optimize filtration efficiency with the lowest headloss and backwash pump power consumption. With a large open area and the lowest headloss, U-shape channel rods and Vee-Wire filtering media support profiles, the Triton Underdrain offers fine slots to suit any filter media specifications. It’s unique bi-directional flow design provides improved bed fluidization, resulting in better media cleaning, which provides longer filter runs, and better water recovery due to less backwash water required. The Triton™ underdrains system is available in stainless steel and PVC and is easier to install than other underdrain designs.
Since 1950, VANTON Pump & Equipment has been manufacturing the most comprehensive line of thermoplastic horizontal (CHEM-GARD) and vertical (SUMP-GARD) centrifugal and rotary pumps on the market. All wetted components are injection molded/extruded homogenous Polypropylene, PVC, CPVC, or Kynar making Vanton’s lineup of nonmetallic pumps chemically inert to fluids across the full pH range and are selected specifically for the dependable handling of caustics, acids, or other corrosive or hazardous fluids, as well as the handling of wastewater and ultrapure liquids.
- No galvanic corrosion or rusting
- Superior resistance to abrasion compared to metals
- Greater chemical resistance over the full pH range compared to metals
- No ionization/metallic contamination of the fluid
- No problems with galling
- Significantly lighter than metal pumps, allowing easier installation and maintenance
- No pinpoint porosity
- No substrate separation
- No expansion differential between metal and liner
- No metal contact due to surface abrasion, nicks or gouges
- No interbatch product contamination: fiberglass composites wick and absorb by capillary action, while solid homogeneous thermoplastics do not
- Superior resistance to abrasion compared to thermoset composites
- Greater chemical resistance over the full pH range than thermosets
Vanton pumps are engineered to solve your specific corrosive, abrasive and ultrapure pumping challenges.
