CASPERON Solution Brings Process, Operation And Cost Benefits To Michigan Facility
CASPERON Solution Brings Process, Operation And Cost Benefits To Michigan Facility

For 15 years, plans to double the capacity of Michigan’s Zeeland Clean Water Plant remained stalled as the City of Zeeland worked toward a joint wastewater treatment contract with two neighboring Ottawa County communities. As a result, maintaining efficient aeration control posed a challenge for the 1.65 million gallons per day (MGD) facility. When expansion plans moved forward in 2016, the city alleviated those problems with the Xylem Sanitaire CASPERON activated sludge solution process, which eliminated the use of lime to treat waste and significantly reduced the volume of biosolid residuals.

OX™ Disc Aerators OX™ Disc Aerators

The bigger and completely redesigned OX™ disc aerator doubles the amount of oxygen transferred by the original Orbal® system disc aerator. This means that the same amount of oxygen can now be delivered with fewer discs, which reduces maintenance, construction and capital costs. It also allows facilities with existing Orbal systems to increase capacity if they replace their existing discs with new OX disc aerators.

Otterbine Fractional Series Aerating Fountain & Mixer Line Otterbine Fractional Series Aerating Fountain & Mixer Line

Otterbine’s 1/2HP Fractional Series Aerating Fountain and Mixer line includes 4 spray patterns and a horizontal mixer – the only unit like it on the market today!

Sanitaire® Silver Series II Diffused Aeration System Sanitaire® Silver Series II Diffused Aeration System

For a combination of high aeration efficiency and low operating costs, there’s the Sanitaire Silver Series II membrane diffuser – the most widely used fine bubble diffused aeration system available today.

Sanitaire® Bioloop® Advanced Oxidation Ditch Sanitaire® Bioloop® Advanced Oxidation Ditch

Reliable and efficient technologies are necessary for the treatment of municipal wastewater. Of the available technologies, the oxidation ditch process is well known for stable operation and reliable effluent quality.

Industrial Aerators Industrial Aerators
The Aspirator transfers oxygen from the water’s surface into the water column through a venturi tube, creating no surface spray.
Bio-Denitro Phase Isolation Technology Bio-Denitro Phase Isolation Technology

Proven phased operation in a simpler package.

Traffic Rated Screen Drain Grates Traffic Rated Screen Drain Grates

Most lift stations and basins require separate drain inlets that do little to keep out large solids such as gravel, branches and general litter than can destroy pumps. ClearBlu has developed a traffic rated grate system that utilizes perforated plate with 1/4″ holes. The grate sits in a heavy grate frame that embeds in concrete. By embedding the frame in concrete, traffic weight is carried by the frame and concrete and not the basin. This allows the basin to be secured and sealed to a poly or fiberglass basin.

Nozzle Manifold Systems & Mixing Nozzles Nozzle Manifold Systems & Mixing Nozzles

Mazzei MTM Mixing Nozzles provide dynamic mixing under pressure, which results in great mass transfer. When used in conjunction with the patented Mazzei® Injector, these nozzles dramatically enhance system mixing and contacting performance. Mazzei nozzles allow the delivery of treatment gases to any depth — all within a compact design, with trouble-free operation and easy installation. Many models are available for various applications.

Blower Rentals Offer Tailored Solution To Temporary Needs Blower Rentals Offer Tailored Solution To Temporary Needs

There are many reasons for a utility to rent a blower for wastewater aeration. Besides the obvious — an emergency — plant operators may need a rental to bridge the gap during upgrade projects, supply seasonal need to supplement air, or perform testing.

A Modular, Energy-Saving Approach To Wastewater Gaining Traction A Modular, Energy-Saving Approach To Wastewater Gaining Traction

A combination of urban sprawl, more stringent environmental regulations, and aging facilities is putting a huge strain on the wastewater operations at many municipalities. The good news is that membrane aerated biofilm reactor technology, also known as MABR, offers a compact and energy-efficient solution.

A Fresh Take On Biological Wastewater Treatment A Fresh Take On Biological Wastewater Treatment

Improving wastewater treatment efficiency requires some type of change in the physics, biology, or economics of the process. In this Water Talk interview, Jeff Kelly, Red Valve’s senior product manager for the Tideflex Aeration and Mixing System, describes how to change all three — to the tune of a cost-saving 50-percent reduction in applied airflow! The Tideflex approach uses a unique diffuser design to support on/off aeration and mixing cycles without clogging. Managed by oxidation-reduction potential (ORP) readings, the novel technique supports a biological selection process that encourages the exclusive growth of facultative anaerobes — the most resilient wastewater microbes, which get rid of phosphates and nitrates without producing hydrogen sulfide.

New Technology Stretches Wastewater Infrastructure New Technology Stretches Wastewater Infrastructure

Population growth, stricter regulations, and increased energy costs continue to exert significant pressure on municipal wastewater operations. But rather than investing in tired, old solutions such as the construction of additional concrete tanks, water system managers are seeking new ways to stretch the limits of their infrastructure.

Transitioning To Turbo Blowers Transitioning To Turbo Blowers

In 2019, Kaeser Compressors assumed control of the venerable line of PillAerator turbo blowers, strengthening its ability to serve the wastewater industry — or wherever else atmospheric process air is needed on a constant pressure level. Watch this video to understand what inspired the decision, as Manual Dias, Business Development Manager at Kaeser, covers the advantages that turbo blowers offer versus other types of blowers. Al Moreno, Kaeser's District Manager, then highlights the company's screw blower technology, followed by Global Product Manager Peter Werhahn, who provides the business case for investing in turbo blowers.

ABOUT AERATION

 

A common first step in the secondary treatment process is to send wastewater to an aeration tank. In an aeration tank, bacterium is used to effectively break down pollutants into less harmful components. Wastewater aeration provides the appropriate oxygen level so that aerobic bacteria can thrive in degrading pollutants such as iron and manganese as part of the wastewater treatment process. Aeration can also be used to destroy anaerobic bacteria that perish in the presence of oxygen. Aerobes that can break down pollutants 10-100 times faster than anaerobes are used most frequently.

Aeration is also used to improve waste lagoons and other waterways such as lakes and reservoirs where oxygen deficiency contributes to taste, odor and pollutant problems. Equipment used for wastewater aeration includes low cascades, jet fountains, spray nozzles, blowers, submerged perforated pipe and porous plates or tubes. Whether the water is thrown into the air via a fountain or diffused by air bubbles being blown or drawn into the wastewater in an aeration tank, aeration works by increasing the area of contact between the oxygen in the air and water.

The most common wastewater aeration process in use today is the air diffusion process, where air is introduced from blowers through diffusion tubes suspended in a spiral flow tank, or in some cases, through diffuser plates in the bottom of the aeration tanks.
