Measuring the sludge level in dissolved air floatation tanks, where the sludge is aerated and floats to the surface, is simplified with the Markland Model 602 Sludge Depth Meter.
Sludge level monitoring
Measuring the sludge level in dissolved air floatation tanks, where the sludge is aerated and floats to the surface, is simplified with the Markland Model 602 Sludge Depth Meter. The meter has four power levels to adjust for different concentrations of sludge. This allows it to find the thick sludge in wastewater treatment plants and also find the very light flocs found in some drinking water plants. The meter is not limited to finding just sludge levels but can also be used to find the level of any interface in a liquid.

Air flow meter
The new ST50 Flow Meter from Fluid Components International (FCI) is now available with a wireless communication option. Using a wireless IR technology built-in to the ST50 flow meter and a standard, low cost PDA, field technicians can obtain measurements, make setting changes and read trouble-shooting codes without ever having to open the instrument. This industry unique feature is ideal in applications for flow meters that are installed in hard-to-reach locations or where opening the instrument is labor intensive.

The Mazzei AirJection® system provides an efficient oxygen transfer but with a small footprint design. With no depth limitations, it is ideal for municipal and industrial wastewater systems. The system comes with a certified Standard Oxygen Transfer Rate and documented Alpha values of 0.9 and higher. The process uses a recirculating pump and patented Mazzei® Injectors to dynamically introduce oxygen into the water system. It is then delivered to the bottom of the pond, tank or reservoir and discharged through Mazzei® Mass Transfer Multiplier Nozzles™ which increase oxygen transfer in the surrounding water.

SolarBee™ floating solar-powered circulators are designed to provide long-distance laminar flow for mixing oxygen in wastewater ponds. The approach conserves dissolved oxygen by distributing super-saturated surface water throughout the pond, thus reducing aerators’ run time by as much as 50%. The circulators can reduce effluent BOD, TSS and ammonia. In addition, they can help solve problems involving overloading, odors and sludge build up. The circulators are constructed from stainless steel and corrosion-resistant polymer.
