Septic chambers
Cultec plastic septic chambers have been widely accepted in most parts of the United States for gravel-less septic leach fields as replacements for concrete galleries and conventional pipe and stone systems. The chambers may receive as much as a 50% square foot sizing reduction in some areas of the country. The septic systems promote higher efficiency than conventional pipe and stone systems by providing greater contact of effluent and soil surface. Perforated sidewalls and full open bottom maximize infiltration capability.

Process monitor, control
Dissolved oxygen and suspended solids are two of the most important controllable parameters in any biological reactor. Stabilizing these two parameters will reduce operation costs and enhance process performance. Insite Instrumentation Group’s Model 2000 will make both of these crucial measurements. The dissolved oxygen sensor is an optical design that eliminates the need for replaceable membranes, sensor caps, cartridges, and fill solutions. The system does not require initial calibration. It uses the fluorescence properties of a rare earth element to detect dissolved oxygen.

Sludge reduction systems
Fluidyne’s Integrated Surge Anoxic Mix – ISAM™ activated sludge system provides tertiary level wastewater treatment with integral sludge reduction all in one process. Sludge reduction is inherent in the system, which has very low power usage through sludge recycling, solids separation, and anaerobic destruction. Sludge production in the process is as much as 85% less than other activated sludge processes. There is no need for separate sludge reduction processes. Anaerobic/Anoxic/Aerobic zones in the biological process provide an ideal environment for BOD reduction and nutrient removal.

MBR system
The Titan MBR™ marries the wastewater treatment engineering expertise of Smith & Loveless with Flat-Plate Membranes. Submerged in the aeration section of the Titan tank, the Flat-Plate Membrane maintains high permeability and flux rates even at peak-day rates. Because the system employs air scouring to prevent fouling, it does not require back-pulsing or the associated equipment and chemical costs typical of other systems. Because of its robust support, flat-plate units also experience less wear and tear than hollow-fiber types and can easily be cleaned in place.
