Industrial Water Treatment Systems

Pre-Engineered Components Engineered into an Integrated Solution

Envirogen Technologies, Inc. has a wealth of experience designing complex water systems ranging from small to mid-size clean water treatment systems to highly engineered custom wastewater treatment plants. This page covers our range of pre-engineered products designed for clean water and waste streams for small to mid-size applications.

Although the individual components are pre-engineered, Envirogen applies our expertise to assess the treatment objectives and evaluate contaminant interactions.

This allows us to recommend and design the most effective, cost-efficient, fully-integrated system to address your problems. We back that system with on-site installation, start-up, and service according to your needs.

The process begins with the definition of the problems faced. In many cases, more than one technology will solve the issue, as shown in Table 1 (below). The key is defining the optimum total solution. Put Envirogen experts to work to solve your water treatment challenges.

Softeners – Envirogen softeners are used to “soften” hard water via an ion exchange process to remove dissolved minerals in the form of Calcium (Ca), and Magnesium (Mg).;

Applications – Prevent scaling of pipes, boilers, and other equipment. Reduce fouling/scaling of RO membranes that results in permanent RO flux decline and loss of water quality.

Tank Construction Materials – FRP or carbon steel softener tanks and polyethylene brine tanks Product Range – Single, Duplex, Triplex and Quad configurations. Electronic valves facilitate regeneration based on time or flow. 

Flow Range – From 4 to 900 GPM
