Hydrotech Media Filtration Provides a Compact & Cost Effective Approach to Primary Treatment

Primary treatment is an important consideration for those seeking to maximize energy recovery.Conventional primary clarifiers require an extensive land area and do not offer significant flexibility to manage removal efficiency.These drawbacks may be overcome through implementation of Hydrotech filters for primary filtration.These advantages result in the Hydrotech filters for primary treatment being an optimal solution for many of today's modern treatment facilities.

Pilot-Scale Evaluation of ANITA Mox for Centrate Nitrogen Removal at the Joint Water Pollution Control Plant

The Sanitation Districts of Los Angeles County (Districts) evaluated two variants of Kruger/Veolia's ANITA Mox process for removing centrate nitrogen at the Joint Water Pollution Control Plant (JWPCP) in Carson, California. One variant was based on the Moving Bed Biofilm Reactor (MBBR) technology, while the other was based on the Integrated Fixed-Film Activated Sludge (IFAS) technology. Two different centrate streams ("Pre-DAF" and "Post-DAF") were tested as feed to the MBBR pilot; one ("Pre-DAF") was tested with the IFAS pilot. Due to dilution by other process water, both centrate streams contained lower concentration of NH4 than typical centrate. Median feed NH4 concentrations during this study were 634 mgN/L (Pre-DAF) and 469 mgN/L (Post-DAF).
