Technology Showcase & News

There are many exciting projects that Hamlett Environmental Technologies has recently completed and it is our goal to share technical information that may assist others with improving the efficiency and performance of their water or wastewater treatment facility. The Technology Showcase provides you with current project updates that may be relevant to your future water or wastewater treatment improvement needs.


City of Cadillac, MI Wastewater Treatment Plant Improvement Project Completed the end of 2008.

Plant wide improvements including Tertiary Filtration upgrade and increased capacity. Stantec Consultants and the City of Cadillac selected Aqua-Aerobic's Cloth Media filter technology due to its compact footprint and proven performance. Three, 6-disk package filter units replaced the aging sand filters and were entirely retrofitted into the existing tertiary building. The upgrade increased the City's filtration average daily capacity from 2.0 MGD to 3.16 MGD and provides a peak capacity of 4.54 MGD with one filter out of service. The Cloth Media solution gave the City of Cadillac state-of-the-art performance while also reducing project costs through reutilization of their existing building.


The Cities of Grand Rapids, Port Huron, Saline, Monroe and Chelsea have cleaned-up their grit solids with Westech's patented CleanGrit technology Project.

Classified grit is wet and odorous.........Not anymore!!!! Just ask these cities who are now enjoying the benefits of Westech's CleanGrit. Click here to see more information on Westech's CleanGrit

The Cities of Grand Rapids and Monroe are realizing big electrical savings with their Turblex blowers and Aeration Control System.

Siemens Turbo Machinery Division provided ultra-high efficiency, single stage blowers and aeration controls to save these two Cities hundreds of thousands of dollars a year. The Cities of Kalamazoo, Grandville and Port Huron have recently made the same decision. Click here to see more information on Turblex's turbomachinery and aeration controls.

The Cities of Wyoming, Grand Rapids, Holland, Saline, Detroit, Bay City and many others are covering up their odor control problems with Conservatek Aluminum Domes and Flat Covers.

Conservatek manufactures a wide array of aluminum cover solutions for all types tanks and channels that will reduce odor emissions and public complaint. Click here to see more information on Conservatek aluminum covering systems.


Innovative Aeration System provides MAXIMUM EFFICIENCY for Lagoon System


The City of Coopersville is expanding their facultative lagoon system to an Activated Sludge process. As part of the expansion, a new aeration system is being added to the lagoon cells along with secondary clarifiers and RAS. The Triplepoint MARS retrievable aeration System was selected by OMM Engineering and the Owner as the basis-ofdesign and is currently being installed by Northwest Kent Mechanical and Triangle Associates Inc. The patented “double bubble” MARS aerator couples the mixing efficiency of a coarse bubble static tube with the high oxygen transfer efficiency of fine bubble diffusers. Individual MARS aerators simply rest at the bottom of the lagoon and utilize the full water depth to maximize aeration and mixing efficiency. Each aerator is accessible and removable for inspection and maintenance from the water surface without having to drain the lagoon.

In addition to the highly efficient Triplepoint diffuser system, Coopersville will also be receiving Siemens Turbo Machinery, single stage centrifugal, premium efficiency, blower packages with a Dissolved Oxygen Control System. These 300 HP blower packages will be housed in acoustical enclosures and utilize dual point control to operate the blowers at their optimal efficiency based on “real time” oxygen demand. The capacity of the blower arrangement can be reduced up to 80% of the design capacity based on dissolved oxygen requirements. Aeration control is also based on the “most open valve” principle and header pressure monitoring to meet the oxygen demand while also maintaining optimum air flow dynamics throughout the aeration system. This innovative system will provide Coopersville the ability to handle variable flow and loading from their local Dairy Processor while keeping electrical and operating costs to a minimum. The system is expected to be commissioned in early 2012.

Installing a Muffin Monster Eliminates Lift Station Pump Plugging

Many Cities throughout the State of Michigan are endorsing the Muffin Monster or Channel Monster as the most cost effective cure for lift station pump plugging and resultant failures. Rain events often create a first flush scouring of interceptors and sewer lines causing masses of rags and grease balls to let loose and flow downstream to the lift station. This often results in instantaneous plugging and failure of the pump. Unplugging a pump that has ingested such material is a very hazardous task due to the presence of needles and other materials that represent a health risk to maintenance personnel. Flooding of households and businesses are also amongst the many concerns of this common event.

It is for these reasons that the Cities of Essexville, Allegan, Ludington, Monroe, Battle Creek, Pontiac, Mt. Clemens, Holland, Trenton, Hastings, Howell and many, many more have cured the problem by installing a JWCE Muffin Monster or Channel Monster in their wet well. These Monsters turn rags and debris into harmless bits and pieces that will easily flow through your pumps. Hamlett Environmental designs and furnishes customized stainless steel support and guided removal frames that make life simple and safe when your Monster needs inspection or repair after many years of rigorous work. Give us a call and we will be happy to evaluate your lift station and prepare a proposal for your consideration.
