Tim Walz, Minnesota State’s Governor, recently toured a Kurita America municipal installation at the City of Bemidji Drinking Water Treatment Plant. The project was among those funded by a recently passed $1.9 billion state bonding bill. Tonka Water, a Kurita Brand , provided five (5) 11’- 6” diameter vertical pressure filters for iron and manganese removal, as well as a PLC [...]
Phosphorus has long been recognized as the controlling factor in plant and algae growth for many lakes and streams. A minor increase in phosphorous can fuel substantial increases in both aquatic plant and algae growth which can have severe impacts on a community. Phosphorous can originate from municipal and industrial facilities that discharge water as well as runoff from agricultural areas that makes its way into [...]
Kurita Water Industries Ltd. (Head Office: Nakano-ku, Tokyo; President: Michiya Kadota) is pleased to announce that it has received the “Distinction Award for Water Company of the Year" awarded by Global Water Intelligence as part of their annual Global Water Awards. This is the second time Kurita has received this award following its first recognition in 2017. The Global Water Awards recognizes the [...]
We know brewery wastewater treatment can be overwhelming with contributing factors including stressors on water supply, risk of water shortage or water pollution. Each of these factors have environmental risks, as well as increased financial costs to your facility. We understand that there are many different wastewater options, including on-site treatment that may include pH neutralization, solids removal [...]
Greensand media has been incorporated into countless filters due to its flexibility and efficient iron and manganese removal in both the municipal and industrial markets. This user-friendly media is commonly found in horizontal pressure filters , vertical pressure filters and in gravity filters where iron is the primary contaminant to be removed. Greensand Media is versatile, able to also extract manganese, hydrogen [...]

Most industrial boiler systems require soft feedwater and without this softening pre-treatment, boilers are at risk of developing hard insulating deposits that reduce the heat transfer efficiency and increase energy use. Severe deposit formation can permanently damage boiler tubes or cause dangerous failures from overheating. Water softening is an ion exchange technique used for removing calcium and magnesium [...]
The city of Bonne Terre, Missouri, had plans to use groundwater from four different wells with varying levels of contaminants. A plan was needed to successfully treat the radium, iron and manganese detected in these sources at two separate sites. With an interest in pre-formed Hydrous Manganese Oxide (HMO) technology, the city made the decision to work with Tonka Water, a Kurita brand, to conduct a pilot study that [...]
A food ingredients production facility had a chronic issue with process leaks in their heat exchangers at their gelatin processing unit. This resulted in product being sent back to the boiler via the condensate. The gelatin is high viscosity which regularly wore out the seals of the heat exchangers. The gelatin, containing hard water, also caused foaming, and eventually significant scale was formed in the water tube [...]
Reverse osmosis is an effective process used to remove dissolved solids that lead to corrosion and scaling deposits in industrial water systems. It can also be used for desalination and removal of nitrates, chloride, and other inorganic compounds as well as softening applications in drinking water systems. To support your RO system and water sources, pre-treatment through media filtration is often [...]
Most people would agree that a traditional coupon is useful! Who doesn’t want to save $3 on box of laundry detergent? But when it comes to water treatment, there is a different kind of coupon to appreciate: the corrosion coupon. Corrosion coupons are used to measure the effectiveness of inhibitor chemistry on corrosion rates in recirculated cooling and heating process water. These coupons are pre-weighed [...]

Background The year 1972 saw the passage of the Clean Water Act (CWA) - an act that provided incentives, penalties, as well as funding for communities to clean their water. The Environmental Protection Agency (EPA), at the time, estimated that over two-thirds of the waters in America were unfit for fishing or swimming; a number that was cut in half after the CWA was established. Almost 50 years later, the [...]
Since airwash was first introduced into filters in the 1960s, it has been widely known that the introduction of air with water achieves greater media cleansing and promotes optimum performance of granular water filters. Simul-Wash™ is a simultaneous air and water backwash system. The Simul-Wash cycle consists of four steps: draindown, combined air/water backwash, air purge, and restratification. The key to [...]
