Engineering Review of Municipal Wastewater Treatment Plant, Oklahoma An engineering review based on several failed Whole Effluent Toxicity (WET) tests. The engineering review had two phases. The first phase was to determine the basis of design for the WWTP by reviewing three years of operating data and to look for any seasonal variation or episodic rain events that could have contributed to the failures. The second phase was to conduct an onsite operation review to evaluate normal operating procedures and conditions at the plant. It was concluded that the WET test failures were tied to reduced nitrification in the WWTP due to rain events and an inadequate food/mass ratio for the treatment of nitrogen caused from insufficient treatment volume.

Water treatment Plant Startup, Thailand Conducted the startup of a 420,000 m3/day (111 MGD) new water treatment plant for surface water treatment located in Thailand. Project included supply and startup of solids contact clarifiers, plus commissioning and startup of chemical feed systems.

Granular Media Filtration Troubleshooting at a Municipal Wastewater Treatment Plant, Florida Low head Granular Media Filter (GMF) inspection and review after poor efficiency resulted in continuous backwash of filters. It was concluded that alum was used as a chemical additive prior to the GMF for algae removal. The dosage and the injection point for the chemical were too concentrated and too close to the filter to make the additive effective, resulting in mud balls forming inside the filter that prevented filtration. The dosage was reduced and moved further
