Advanced onsite wastewater treatment requires precise control - over water levels, ATU operation, dosing and more.
Manufacturers offer a wide range of control, monitoring and alarm solutions for a variety of onsite applications. Here is a sampling of the latest from companies that responded to a request for information from Onsite Installer.
Floatless technology
SJE-Rhombus offers the C-Level sensor, a floatless technology for use with selected Installer Friendly Series control panels. The sensor detects the liquid level in the tank and sends a signal to the IFS panel, which displays the level in inches or centimeters. Pump activation and alarm levels can be adjusted using the touch pad on the inner door of the panel, eliminating the need to go into the tank for manual adjustment. The unit is well suited for confined-space applications. 888/342-5753; www.sjerhombus.com.
Self-contained power
The multi-function Aero-ALERT alarm system from Aero-Stream LLC is designed to fit any septic system or holding tank in residential or commercial settings. The design includes a self-contained power cell that simplifies installation and mitigates the need to procure a separate electrical permit.
The installation requires no licensed electrical contractor. The unit can be used in virtually all systems requiring an alarm. It can be remotely located up to 100 feet from the tank. Because it is low-voltage, the cord needs to be buried only inches below the surface. The device uses high-efficiency electronics including a 95 dB audible and a 360-degree flashing visual signal. This allows the unit to emit a continuous alarm for more than 2,000 hours (90-plus days) without depleting the power source. 877/254-7093; www.aero-stream.com.
Multiple configurations
Aerobic environmental control panels from Alderon Industries provide solutions for many aerobic treatment systems. Options include multiple configurations for alarm beacons, buzzers, float switches, air switches, circuit breakers, 24-hour timers and more. The float switches that come with the control panel are labeled for quick and simple installation. The terminal blocks are easily accessible, and the panels are UL listed. A schematic is laminated on the inside door of the control panel, and an operation and maintenance manual is provided with each control box. 218/483-3034; www.alderonind.com.
Peak-flow reduction
Simplex unit TPA-350 and Duplex unit DCU-200 from Premier Tech Aqua are useful at onsite treatment systems requiring timed dosing with one or two single-phase pumps. The display allows for quick adjustments of the pumping and rest times and gives a complete picture of system utilization. The device allows for peak-flow reduction and control of the influent to the treatment system according to the needs of the installation. It consists primarily of a control panel allowing variable on-off time settings and controlled dosing of wastewater flows to the treatment system. 418/867-8883; www.premiertechaqua.com.
Expanded data capacity
MVP control panels from Orenco Systems feature a programmable logic controller with expanded data capacity. The Siemens LOGO! digital programmable logic module, with an LCD display and programming keys, enables service providers to adjust timer settings in the field quickly and accurately. Visual float position indicators, an elapsed-time meter, and counters for alarms and power faults make troubleshooting easier. Panels differentiate high- and low-level alarms and reactivate silenced alarms after 12 hours. 800/348-9843; www.orencocontrols.com.
Fouling-resistant
The Model 3G onsite wastewater disinfection unit from Salcor Inc.includes fouling-resistant Teflon that requires only annual maintenance, a two-year lamp life, and increased protection against the effects of flooding as demonstrated in a 28-day underwater operation test. 760/731-0745.
Tracking pump cycles
PMJB units from Septronics Inc. automatically keep track of how many times the pump cycles. The exterior NEMA 4X junction box pump control is outfitted with a removable terminal board supporting a built-in event counter. Every time the pump engages to pump out the tank, one pump event is added to the counter.
The unit sits on a high-impact poly pedestal to protect the wiring. It also has an area to connect through to the tank, with the pipe nipple and locknuts included with the unit. The interior Tankmate pump alarm comes with a control float switch that is wired into the terminal strip on the same pump control terminal board in the junction box. 262/567-9030; www.septronics inc.com.
Reduces bacteria levels
The PL-UV1 UV disinfection unit from Polylok reduces bacteria levels from secondary effluent to achieve strict water-quality standards. The unit offers dual-pass design, weatherproof electrical components, and a long-life UV bulb. Flow rates are 100 to 8,640 gpd (gravity flow only). 877/ 765-9565; www.polylok.com.
Indoor/outdoor alarm
The LB50 indoor or outdoor high-water alarm from Septic Services Inc. has a level control and features a warning light, audible alarm, remote alarm for commercial systems, and a three-position toggle switch for operate, silence and test. To install, technicians connect the level control switch to the terminal blocks, then plug the unit into a 115-volt outlet. The unit is fused for circuit protection and has a remote alarm for switches that close on signal (0.4 amps at 115 volts AC). 800/536-5564; www.septicserv.com.
