  • Nitrate Removal System

    Nitrate Removal System

    H&T has extensive experience in the field of removing nitrate from drinking water. We have built anion exchangers as part of demineralizer systems to treat boiler feed water in power plants since the 1950s. Having installed many large demineralizers for some of the largest electric utilities in the country, H&T has a long, established background in ion exchange.

  • Skid-Mounted Vertically Orient Filtration System

    Skid-Mounted Vertically Orient Filtration System

    H&T uses co-precipitation followed by filtration as the preferred method for removal of arsenic from drinking water. There are many methods available to remove arsenic including ion exchange, RO and adsorptive processes. However, we feel the co-precipitation process is the easiest to operate and most economical. Often, arsenic will be present in combination with iron and/or manganese. When iron and manganese are in the water, it is necessary to...

  • Radium Removal System

    Radium Removal System

    There are several methods to remove radium from drinking water. It can be removed by ion exchange, adsorbed or precipitated and filtered. Radium will be removed in sodium cycle cation exchange (the water softening process). After the service run, the resin is regenerated with brine and the radium is regenerated off the resin and concentrated in the waste brine. Radium can also be removed in a co-precipitation process similar to removing arsenic.

  • Greensand - Model Plus - Greensand Iron & Manganese Removal Filter

    Greensand - Model Plus - Greensand Iron & Manganese Removal Filter

    H&T developed and patented the continuous regeneration process for iron and manganese removal in 1963.

Our method became the industry standard for the next 40 years. In 2005, H&T introduced GreensandPlus, the next generation in manganese...

  • Water Softeners

    Water Softeners

    The H&T water softener system utilizes cation-exchange resin operating in the sodium cycle with salt (NaCl) regeneration to remove the hardness ions. Calcium and magnesium will exchange for sodium on cation resin. This reduces the hardness and increases the sodium in the treated water. For industrial applications, it is typical to treat 100% of the water to achieve the lowest hardness. For municipal potable applications, a portion of the water...

  • Skid Mounted Weak Acid Softener

    Skid Mounted Weak Acid Softener

    The H&T Weak Acid Cation (WAC) softening process can be used in applications for removal of both iron and hardness in a one-step process, or where softening is needed but an increase in the sodium level cannot be tolerated. Weak Acid Cation resin is extremely efficient and makes excellent use of the regenerant. The resin operates in the hydrogen cycle instead of the sodium cycle, so hydrogen ions are exchanged for hardness instead of sodium. Acid...
