ATI’s Model Q46/88 Suspended Solids Monitor provides real time monitoring of suspended solids in a variety of water and wastewater applications. A submersible sensor immersed in process tanks or effluent channel senses particulates in the water using an optical backscatter technique that allows measurement over a wide range. Results are displayed on the Q46 electronic unit mounted near the sensor with a variety of outputs provided as standard.
Monitoring suspended solids in wastewater and industrial process water can be useful for either process control or for alarming of unusual conditions. In biological treatment systems, monitoring suspended solids in the aeration tank can assist operators in maintaining optimum MLSS (Mixed Liquor Suspended Solids) concentration. In industrial clarifier's, suspended solids water quality monitoring can warn of upset conditions that might result in the discharge of solids that exceed plant permits.
Suspended solids sensors are optical devices operating in the infrared region. Unlike turbidity sensors that use 90 degree scatter to optimize sensitivity, suspended solids sensors use “backscatter” to allow solids measurements at much higher levels. Operation with infrared light ensures very long sensor life and minimizes the effects of changing sample color.
Sensors are designed to withstand the rigorous conditions of wastewater and industrial process streams and to last for years of service with nothing more than occasional cleaning of the sensing surface. There are no protruding surfaces near the sensing element to avoid accumulation of fibrous materials. The sensor is simply pipe mounted using mounting adapters available from ATI.
Optical sensors used for monitoring biologically active systems such as aeration tanks or aerobic digestors will require periodic cleaning to maintain the integrity of the measurement. Biological slime deposited on the optical surface will degrade the ability to transmit IR light into the sample. The frequency of cleaning varies widely depending on the turbulence in the process. Course bubble diffusion systems tend to scour the sensor while fine bubble diffusion systems result in more rapid sensor fouling.
Cleaning can be done manually by simply wiping the sensor as needed, but ATI also offers an automatic air-blast cleaning system as an option. The “Q-Blast” air cleaning system is controlled by the Q46/88 Suspended Solids Monitor and provides a compact air compressor system that periodically applies pulses of compressed air across the optical surface to remove accumulated biofouling. This system greatly reduces the requirement for manual maintenance, with cleaning frequency programmed to occur as often as necessary.

An understanding of climate change’s effects on the environment has become commonplace and grows every day, but one researcher from Florida State University is looking to answer a new question: What are climate change’s effects on people’s health? In one of the first studies of its kind, Chris Uejio, an assistant professor at FSU, and a team of researchers studied how climate change can affect the roughly 20 million Americans (according to the Environmental Protection Agency) who consume untreated drinking water on a daily basis. Because climate forecasts are predicting higher rainfall rates over the next few decades, coming down in intense storms, Uejio said those flashes could cause flare-ups in waterborne illnesses.Read More
We put together this infographic on data buoys for our Spring 2017 edition of the Environmental Monitor ( PDF available online ). Organizations across the globe use data buoy systems to observe and monitor atmospheric and oceanographic conditions in remote locations. Measurements range from air pressure, humidity, wind speed and direction to wave height, water temperature, dissolved oxygen and other water quality parameters. With the help of national and international networks, reliable and comprehensive data sets are made available for research and public safety.Read More
The Spring 2017 Environmental Monitor is on the way to subscribers this month. Our quarterly print editions feature the best of the Monitor's coverage from the past few months with added photos, graphics, updates and the latest monitoring gear. If you don't have a print subscription, you can sign up for free. If you'd like to peruse some of our past editions, check out our print archive . In this edition, we showcase a number of projects that are truly advancing the way data are gathered in the environmental monitoring field. This includes a look at the first-ever deployment of the ESPniagara in Lake Erie, a device for real-time microcystin measurements that is so advanced its makers say it is essentially a robot.Read More
