Lake Vermillion State Park, MN Treatment System Commissioned

A new Tonka Water treatment plant located in Lake Vermillion State Park, Minnesota was commissioned. This system treats Lake Vermillion water using ultrafiltration membranes and carbon filters.  Tonka Water provided a DTS™ (Delivered Treatment System), a complete "plug and play" treatment system in a prefabricated building.

Tonka Water Commissions Treatment System in Missouri

A new custom-designed Tonka Water treatment system was commissioned for the private Eagle Sky of Ozarks campground in Missouri. This unique and innovative system treats surface water using Tonka Water's fully automated ultrafiltration membrane technology to remove turbidity.

Tonka Water Project Featured in North Dakota Water Magazine

A project awarded to Tonka Water was featured in the March 2014 issue of North Dakota Water magazine. The project, to be constructed in Dickinson, ND, will feature a UF Membrane filtration system, and will produce 18 million gallons per day. Read the full article after the jump!

Biological Treatment of Ammonia and Other Contaminants

By Bryan Oakley, PE

Many treatment plants throughout the country have been surprised to find ammonia in their water. Ammonia exists naturally in a significant number of groundwater aquifers and is present in water reclamation plant effluent. Ammonia reacts with chlorine disinfectants, increasing disinfection doses and can cause objectionable off-taste and odors .

Ammonia can also accelerate corrosion of residential, commercial and industrial copper plumbing and cooling systems. This corrosion can raise copper concentrations at water reclamation plants, and if released to rivers and lakes at elevated levels, can be toxic to aquatic life.

Biological Filtration of Drinking Water
An economical and innovative way to treat ammonia and other related contaminants is through a biological treatment process. Instead of using chemicals, naturally occurring biology can oxidize contaminants such as ammonia, iron, manganese and organics that can then be removed by filtration.

Baker Water Treatment Plant

Nearly two years ago, Hardy County needed a small facility to test their water before the construction of their new water plant. The county chose a 20 gpm pilot trailer plant to test the high turbidity water for a twelve week period. After testing the water, the project was split into two phases. Phase I involved bidding a site security package while Phase II involved getting permits, certificates and building the new plant. Construction of the new plant began near the end of 2010.

The new Baker Water Treatment Plant removes high levels of turbidity, iron, manganese, and organics. The plant uses two surface water pretreatment systems for turbidity removal, two Ultrafiltration membrane systems for bacteria and virus removal, one clean in place system, and a Master PLC control panel to automate cleaning and operation.  How it works: Water from Parker Hollow Lake is pumped through the Unitized Treatment System, which combines flocculation, clarification and filtration to remove the large contaminants, then pumped through the membrane system, which removes the microscopic contaminants. Chemicals are added before the water is collected into a storage tank where the water is gravity fed through lines.

With the start up in January 2012, the community of Baker officially has clean water.

How Good is Your Pilot Study?

by Tom Davis
President, Tonka Equipment Company


A good design starts with a careful and complete water analysis – because all waters are different and respond differently to treatment.  Frequently, a water analysis alone may not be sufficient information to conclusively move toward a final design, and in these cases, a pilot study is required.  A dependable, high quality pilot study, like many services encountered in the water industry, is reflective of the ultimate relationship an engineer or City may have with a chosen responsible manufacturer.

New Ultrafiltration Membrane Treatment Pilot System in West Virginia

Ultrafiltation Membrane Pilot

In the scenic area of Hardy County located just 100 miles from Washington, DC, Tonka piloted its new Ultrafiltration Membrane packaged treatment system. This customized system incorporates flocculation, sedimentation and ultrafiltration – a water treatment package along with full manufacturer system responsibility.  


The Tonka UF membrane pilot trailer is a self-contained unit suitable for either existing applications or “greenfield” sites. We pull it up, drop it, connect power, drainlines and water source, and it’s ready to go. The pilot unit can tackle surface water with organics as well as groundwater sources with iron and manganese and other contaminants. The Dow UF membranes also provide removal credits for cryptosporidium, giardia and viruses under the limits as determined by State regulators.
