WATER TREATMENT AERATION
WASTEWATER AERATION BLOWERS
The most common and preferred process in treating water and wastewater is through aeration, either by introducing compressed air directly into and through the water, or by mechanical diffusion (sprinklers, sprayers, propellers, or pumps) or both, the process encourages the natural microbial degradation of organic matter. Interestingly the cost of generating the air supply represents more than 50% of the energy usage at a typical waste treatment plant far exceeding that for pumping the waste itself. Thus any means for monitoring and improving the efficiency and effectiveness of air usage could significantly reduce the cost of plant operations.
There are many techniques for monitoring aeration air flow in a waste water treatment application. Historically, differential pressure orifice plates, vortex shedding, and turbine flow meters have been used. Problems inherent with these technologies such as wear on the plates, bearings, and blades and blockage in the sensing elements have sent engineers looking for a better approach. Today you will find the preferred technique to be a thermal based mass flow meter. A simple single pipe penetration insertion meter, with accuracy and repeatable air measurement over the broad range is seen to be the ideal solution for the wastewater aeration air monitor need.
Delta M offers its TrendMassTer, TM6000, series air thermal mass flow meter to meet the needs in this wastewater aeration application. This simple to install insertion sensor has no moving parts or orifices to clog for maintenance free operation. The meter can be mounted with local electronics, or remotely to a control panel box or control room. The data displayed or available through RS485 show current flow rate, cumulative total flow, and temperature. For a Repeatable, Reliable, and Ready solution for your aeration air flow meter needs give Delta M a try. You will not be disappointed.
