Self-aspirating aerator
MTS/Mass Transfer Systems designs and manufactures the MTS Aspirator™ submersible self aspirating aerator for industrial and municipal water and wastewater treatment. The technology is currently finding applications for small tanks needing aeration or for supplemental aeration in larger processes. The aspirator is designed for a variety of applications where oxygen transfer and mixing are required along with portability. Its design places the aerator at the bottom of the tank and creates distinct zones of influence for aeration and mixing.

Modular wastewater treatment
An advanced, modular wastewater treatment and recycling system – using technology originally designed for the US Military and the oil and gas industry – is now available from Global Water Group. The extended aeration/activated sludge wastewater treatment system processes water in half the time of conventional aeration systems. Using modular units, the system operates in combination with a separate recycling unit and a purification unit. The systems can be sized to handle flows from a few thousand to tens of millions of gallons per day.

Respirometric BOD
The Oxi700 BOD System from Orbeco-Hellige meets Standard Methods for the Examination of Water and Wastewater (Method 5210 D) and is ideal for process control. Available as a 6 or 12 sample system, the instrument produces precise BOD measurements based on the manometric principle. Manometric respirometers regulate the oxygen uptake with the change in pressure caused by oxygen consumption while maintaining a constant volume.

MBR modules
The Toray "Membray" submerged flat sheet membrane bioreactor (MBR) module, when used as a component of a MBR system, effectively removes suspended solids from activated sludge. This microfiltration module in a plate-and-frame configuration consists of flat sheet PVDF membranes that are caste on a polyester, non-woven fabric as the base layer. This combination of materials gives the membrane physical strength and chemical stability. Using membranes with a high density distribution of 0.08µ nominal pores to separate sludge ensures treated water free from suspended solids.

Ammonium analyzer
Featuring ISE technology, the new Hydra Ammonium Analyzer from Electro-Chemical Devices can be used to monitor the ammonium nutrient load directly in the aeration basin of a wastewater treatment plant as well as environmental waters, lakes, streams and wells. The analyzer measures the concentration of dissolved ammonium nitrogen (NH4+ -N) in all kinds of water using three electrodes: an Ammonium Ion Electrode, a Potassium Ion Electrode and a pH Electrode. The analyzer is designed to automatically compensate for the pH dependant concentration equilibrium and potassium ion interference on the ammonium electrode.

TOG/TPH analyzers
InfraCal TOG/TPH Analyzers from Wilks Enterprise provide accurate on-site analysis to assist regulators, as well as industry, to reduce the build up of fats, oils, and greases (FOG) in sewers. These analyzers are ideal for use by publicly operated treatment centers as it is important to locate and monitor sites that are suspected of dumping high levels of FOG into the sewer line. In addition, numerous industries need to ensure they are not exceeding their oil/grease discharge permit limits. Waiting for remote laboratory results can take several days to a week.

Turbo blowers
HSI has introduced its new air-bearing HT Series blower. The new High Speed Turbo Blowers can reportedly provide a 20-40 percent reduction in energy costs and require less maintenance. The only scheduled maintenance is routine inlet filter changes. The series is quiet, with less than 80 dba per OSHA standards. They are shipped as a pre-engineered working system with integrated controls, variable frequency drive, filter inlet, and electrical disconnect. Further energy savings could be realized when using the HT blower's "plug and play" control system.
