AERATION & BLOWERS RESOURCES

• Municipality Looks To Expand Plant Capacity While Reusing Existing Systems

  Sharjah Municipality of the Untied Arab Emirates (U.A.E.) was requiring to treat more and more flow despite having very little space for new treatment systems. They were looking at wanting to expand their plants No. 4 & No. 5 plants to meet new total nitrogen limits and try to do so by having to reuse the existing systems. This type of upgrade would save on cost as well as space at the plant.

• IFAS System Produces High Quality Effluent In East Central Kansas

  The City of Emporia, in East Central Kansas, recently experienced an increase in population and more stringent effluent permit requirements resulting in a strained wastewater treatment plant. Emporia retained the services of a local engineering firm to evaluate the current and future needs of the system and recommend an economical, sustainable, and effective solution. After evaluating several options, World Water Works’ Integrated Fixed Film Activated Sludge (IFAS) conformed to all the requirements and was selected.

• Treating Food Wastewater Efficiently Using Jet Aeration

  Food processing is a water-intensive process, and its wastewater byproduct is typically high in volumetric daily flow and also biochemical and chemical oxygen demand (BOD and COD), organics, and nutrients. Consequently, significant on-site treatment and resources are necessary.

• Memorial Park Pump Station, Tauranga City Council

  The Memorial Park Pump Station (MPPS) transfers wastewater flows from Memorial Park to Chapel Street WWTP and/or Te Maunga WWTP. It is a large pump station (PS) installed within a 9.0m diameter concrete structure. The pump station is approximately 12m deep, with a 6.5m maximum water depth and split into several compartments.

• Reducing H2S And FOG At The Discharge Of A Force Main

  Beginning early in 2019 our office began receiving complaints of sewer odor in the neighborhood of Fountain Ridge Section III (FR III), located in Prince George County VA. The County Operations staff investigated the wastewater collection system that serves the neighborhood, and found that odor was proliferating throughout the neighborhood. Corrosion of the sewer manholes was clearly evident.

• 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.

• New Turbocompressors Boost Efficiency At Wastewater Plant

  Sulzer engineers helped a plant in the Netherlands cut its energy costs with a turnkey project

• Mixing Made Easy For Low Energy Lakes, Ponds, And Lagoons

  Landlocked, shallow bodies of water such as recreational ponds, irrigation, drinking water and animal waste lagoons have a major problem with flow. The only natural methods of movement in these bodies of water are the slight Coriolis Effect of the earth and wind. Neither of these natural mixing sources is sufficient to allow shallow water bodies to respire and deal with the natural biological degradation of wastes and detritus that eventually form on the bottom. Eventually, external problems will occur – algae begins to form in abundance, odors will emanate from the water due to stagnation, blue-green cyanobacteria will form on the surface and cause more odor and toxicity, and eventually the water is no longer capable of supporting basic aquatic fauna reproduction.

• Leveraging Rentals For Pneumatic Conveying Applications

  Pneumatic conveying applications are critical to many facilities – when you can’t move material you can’t make or sell your product. Because of a historical lack of availability of specialized rental blowers and compressors for pneumatic conveying, plants often ether accepted the production outage or rented a more readily available 2 stage oil-free rotary screw compressor designed for 90-150 PSIG plant air service that is very inefficient at the reduced pressures needed for pneumatic conveying.

• Saving The Most Money On Wastewater Aeration: Bringing It All Together

  The power required for aeration is 50 to 60 percent of the electric bill for a municipal wastewater plant, sometimes accounting for up to 4 percent of the associated community’s total power. Energy efficiency is a critical factor in evaluating blower performance.
