Ammonia Control in Aquaculture: What you need to know
Every fish farmer knows about ammonia. It’s a constant battle, especially in warmer months, to keep levels low and your fish and shrimp healthy. But what is ammonia? Why does it cause problems in aquatic life? Outside of testing, what are the best steps you can take to eliminate ammonia? Here, we outline the answers to those questions. Understanding Ammonia Ammonia, as a colorless ...

Improved plant discharge Quality using the IDEAL system
Miner, Mo., population 980, is a quaint rural community located halfway between St. Louis and Memphis, Tenn. The 20-year-old Miner Wastewater Treatment Plant faced a number of technical issues in 2012. The town’s old three-cell 0.302 MGD aerated lagoon had high levels of suspended solids. Its ammonia and nitrogen concentrations were above their targets. “There was quite a bit wrong ...

Pasco County uses total life cycle costing to select chloramination analyzers - Case Study
Pasco County, Florida Water Utilities serves its customers with water from its 58 permitted wells blended with the water supplied by its large regional supplier, Tampa Bay Water. In 2002 Tampa Bay Water converted to monochloramine disinfection because of its advantages over free residual chlorine. Monochloramine is more stable and better extends the disinfectant residual throughout the ...

3 High-recovery, low-waste filtration technologies to know about
Today, water sustainability is a priority for most cities and states. For utilities, this means investing in filtration systems that are not only cost-efficient, but also produce high water recovery and low amounts of waste. These systems can help to conserve water and limit the discharge of hazardous wastewater into waterways, which are typically heavily regulated by local authorities. ...

Tampa Switches to Chlorine for Water Treatment
Many Tampa residents received a notice in the mail a few days ago alerting them that the city is temporarily changing their disinfecting agent from chloramines to chlorine. The notice, which you can read in full below, claims that this procedure is merely routine maintenance and that the water will still be safe to drink. Citizens who aren’t familiar with water treatment methods may read ...

How Does the Membrane Aerated Biofilm Reactor Work?
Aerobic digestion and nitrification-denitrification work together thanks to an innovative membrane system One of the most talked-about new wastewater treatment technologies is the membrane aerated biofilm reactor (MABR), which is revolutionizing WWT. The discussion, however, has mainly focused on issues like MABR technology’s low operating expenses, high energy efficiency, low ...

Application of advanced Respirometry in the Nitrification assessment for different levels of Temperature, pH and Oxygen
Abstract Environmental factors control the rate of nitrification. For a determined substrate concentration, the most significant environmental factors are temperature, pH and oxygen availability. The well known critical influence of those factors on the nitrification are here analyzed by making use of a specific software and advanced respirometry based on a dynamic LFS system, where the test ...

Major waste management company and cbio combine resources, to resolve a breach of ammonia consent, in a large wastewater treatment plant case study
The WWTP itself is located in the East Midlands, and treats dairy waste from a large processing plant, treating c1,500m3 of effluent per day. On 30th July the ammonia (NH3) levels in the permeate from the MBR at the plant began to increase. The effluent plant discharges to a river and as such, the consent limit is stipulated by the Environment Agency at 4mg/l. Within three days, the ammonia ...

Southwest landfill case study
The Problem: A landfill located in Texas was experiencing high concentrations of ammonia in the leachate from their domestic landfill. Compliance standards were becoming more stringent at the same time ammonia and BOD levels in the leachate stream were increasing in concentration. The Solution: After on‐site testing of a bioFAS High Rate Bio Filter (HRBF) process for a period of 1.5 years, ...

Overloaded treatment plant case study
This case provides a typical example of how the combined approach of boosting organic degradation and nitrification can be used successfully to achieve effluent discharge consent levels in overloaded treatment plants. The case concerned a large caravan park and leisure facility effluent treatment plant in the south of England. The Manager of the site explains “before we were introduced to ...

Models for nitrification process design: one or two AOB populations?
Models for engineering design of nitrifying systems use one ammonia oxidizer biomass (AOB) state variable. A simple extension using two AOB populations allows a more accurate prediction of nitrification systems at switching process environments. These two AOB subpopulations are characterized by two different sets of kinetic parameters. Selection pressure and competition between the two functional ...

Urine nitrification and sewer discharge to realize in-sewer denitrification to simplify sewage treatment in Hong Kong
The chemically enhanced primary treatment works in Hong Kong will be upgraded for biological nitrogen removal. This study proposed a novel approach to waive the upgrading by urine source-separation, onsite nitrification and discharge of nitrified urine into sewers to achieve in-sewer denitrification. Human urine was collected and a lab-scale experiment for full urine nitrification was conducted. ...
