Advanced Water Purification and Innovative Water Sampling
Municipal waste water treatment facilities and government agencies are increasingly concerned with the existence of bacteria, viruses and emerging contaminants such as hormones and pharmaceuticals in drinking water. To effectively concentrate these toxic constituents during sampling and rapidly remove them, WRI has developed a nano-structured composite that carries positive surface charges and possesses unique interlayer structures that can remove negatively charged (anionic) molecules from waters on contact (adsorption). Successfully removed constituents include but are not limited to arsenic, selenium, viruses, bacteria, and endocrine active compounds such as hormones and pharmaceutical chemicals.
Automated Flocculation Titrimeter
The Automated Flocculation Titrimeter (AFT) automates the collection of Heithaus values, allowing users to easily and reliably predict which heavy oils and petroleum residua (including asphalts) can be mixed without causing phase separation. Typically, refiners have stopped processing too soon because they couldn’t predict when coking would occur. They’ve stopped well short of coke formation to avoid fouling in heavy oil processing equipment, tanks and transfer lines but have reduced the distillate yield. Used with WRI’s patented Coking Indexes, the expanded AFT methodology allows you to recover additional distillate without fear of fouling. The AFT lets you quickly and easily collect the data needed by the Coking Indexes to predict the refinery conditions for coking, so you can stop processing before fouling occurs but not sooner than necessary.
