Emerging Chemical Concerns

Many adverse ecological effects have been attributed to pharmaceutical and personal care products (PPCPs) and endocrine-disrupting compounds (EDCs), but it is not clear what risk they pose to human health. In the past, water was known to contain these chemicals, but the exact amount was difficult to quantify. Recently, these chemicals have gained much more attention.

The new D14–14 GPM series of chemical injectors are powered by water flow, reducing energy costs. They accurately and continuously inject chemicals at the point of application. Variations in water flow or pressure do not affect operation, offering consistent, repeatable results. Their precise ratio adjuster allows for minute adjustments, enabling the user to control chemical costs.

Activated Carbon

Activated carbon is an excellent adsorbent due to its large surface area and the fact that the diverse surfaces can take on many different types of contaminants.

Preserving Pipelines

Well-maintained and functional sewer systems are a major asset in any community, but they require regular cleaning, inspection and maintenance. Chemical grouting too often is viewed as a stopgap measure to reduce groundwater infiltration. In reality, grouting does much more to maintain sewer line integrity. It also is a soil-sealing process that stabilizes the sewer bedding soil, preventing washout of bedding fines and resulting pipe misalignment and joint failure.
