Drewzyme™ bacterial cultures
Many biological wastewater treatment systems are limited in their ability to perform as required due to channeling in lagoons, higher than design flow rates, highly variable food and nutrients and other system upsets. Plant outages, spills and cold weather are common sources of upsets in biological systems. Bioaugmentation is an effective way to enhance the performance of biological wastewater treatment systems.
Drewzyme bacterial cultures are blends of selected strains of active bacteria that effectively remove biological oxygen demand (BOD) from
industrial effluent under a wide range of conditions. Feeding the Drewzyme cultures helps improve the performance of poorly performing wastewater treatment systems by introducing a high concentration of active bacteria that provide an immediate boost to the system. Drewzyme cultures are effective in activated sludge systems and aerated lagoons. Specific blends are available that thrive under cold weather conditions, effectively maintaining BOD removal targets even during the cold winter months, where typical system bacteria are very slow to metabolize BOD.

Customer Analytical Services
Ashland Water Technologies’ Customer Analytical Services team is dedicated to helping customers address the multitude of contaminants that can negatively impact the efficiency and reliability of their water-based systems. The team is made up of an experienced staff of analytical chemists, microbiologists and technicians and is supported by sophisticated testing equipment that provides rapid analysis and identification of contaminants beyond what may be accomplished with field-based methods. Key services provided by the team include fluid analysis, deposit analysis, microbiological analysis and metallurgical analysis.
Corrosion Monitoring and Metallurgy
Problems related to corrosion cost commercial and industrial plants billions of dollars each year. Although a variety of means exist to inhibit corrosion, it's important to identify the root cause of the corrosion. Ashland Water Technologies’ Corrosion Monitoring and Metallurgy group provides failure analysis and assessments of steam-generating and heat-exchanger equipment. Working closely with customers, this team provides clear identification of the problem, which leads to a more rapid and effective solution. Key services provided by the group include failure analysis, corrosion coupon analysis, and elemental and compound analysis.
