The purposes of this technical memorandum are briefly outlined as:
- To evaluate the wastewater discharge payment method used by Metro Wastewater Reclamation District (METRO).
- To develop a wastewater discharge payment model applied to Industrial Park Water and Sanitation District (District).
- Based on the wastewater discharge payment model (Payment Model), to predict the District’s wastewater discharg

A newly upgraded 500,000 gallon per day wastewater system has a large industry that produces biocides. Biocides are made to disinfect and kill bacteria, viruses, and germs making them toxic to wastewater biology.

A three lagoon system in central Illinois receiving 25,000 gpd was getting bad odors every spring during “turnover.” Turnover is when the water warms in the spring, lifting the compact sludge up. Their large lagoons were about 6ft deep with around 2ft of sludge. They have no aeration but enough wind action to give it white caps. They need to minimize the sludge buildup, but like every city they were on a budget. &nbs
SAMPLE(s): “SBR”
TEST 1: reduce foam and NH3 (also COD) with Aquafix products
- Goal: reduce foam and improve nitrification
- Test dates: 5/7/12 – 5/11/12
- Set up: 32oz glass straight sided jar + 400ml mixed sample + D.O. 2mg/L + 20ppm per day products for 5 days
Challenge
Dave and Mike operate a pond system with one 4 acre and two 1 acre lagoons in a town noted for its famed Italian restaurants. A manufacturer in town produces frozen dinners and their discharge is about 110°F. These high temperatures create low D.O. conditions that cause odors in the lagoon. Under further investigation, we found the industry was sending loads of cheese to Dave and Mike.
Challenge
Greg and his team have a 3 cell system, one 6 acre lagoon and two 2 acre lagoons, that were becoming inundated with sludge. The ponds were about 30 years old, not aerated, and have never been dredged or treated to remove sludge.
Challenge
A small village had bad corrosive hydrogen sulfide odors coming into their wastewater treatment plant. It was a hot, dry summer and the odors were really bad.
Challenge
A brewery had a yeast outbreak and it caused bad foaming, poor settling, and bad effluent. The problem persisted for a couple of months until they called us.
Challenge
A 3 MGD Texas wastewater treatment plant received numerous neighboring complaints about odors. This operator used multiple odor masking agents from Jan-San and wastewater supply companies with little success. The operators were looking for options that would neutralize the sewer odors instead of just mixing with them.
Nitrification is one of the most critical biological processes in wastewater treatment, playing a central role in protecting receiving waters, meeting regulatory requirements, and maintaining overall plant stability. Despite its importance, nitrification is also among the most fragile treatment processes. It is highly sensitive to environmental changes, operational upsets, and toxic events, and it is often the first biological function to fail when conditions become unfavorable. A clear under
