Because of this,AX-Max configurations vary and recirculation pumps for these units are determined on a project-by-project basis.Contact Orenco for more information. AdvanTex TCOMTM Control System The TCOMTMControl Panel is a telemetry-based panel—which can be connected to a landline,cellular service, Internet,or satellite service that controls all sensors and pumping equipment.TCOM panels are an integral part of all commercial AdvanTex Treatment System equipment packages.Telemetry provides real-time operator monitoring and control of system components,as well as remote data collection of key opera- tional parameters and events. Its communication function provides notice to system operators in the event of an alarm.Operators can call into the control unit,determine the cause of the alarm,and—often—address the situation without having to be physically present at the treatment facility. The TCOM unit can be programmed to use trend data for adjusting timer settings automatically,based on established recirculation ratios,so frequent operator adjustment is not necessary for systems with flow variations. If additional equipment for pretreatment,tertiary treatment,or disinfection is required,the controls for each component can easily be incorporated into the TCOM control panel.This allows Orenco to contact the panel directly to assist the operator in system evaluation and troubleshooting or to manually override operations.TCOM control panels can also integrate into existing SCADA systems. Consult with Orenco early in the design process to discuss any integration needs. Orenco's TCOM control panels are available with multiple enclosure types; however,for ease of operation,they should be protected from direct sunlight to protect the electronics and allow the operator access without direct exposure to the elements(rain,snow,etc.).This should be taken into account when determining location of the control unit.Shelters are recommended for panels whenever possible.Contact Orenco for a quote. AdvanTex System Ventilation Proper ventilation,achieved by active or passive ventilation, is critical for maintaining aerobic treatment processes in AdvanTex Treatment Systems. Active Ventilation Active ventilation is the preferred means of ventilating AdvanTex Systems and is required for the following systems: • All systems with design maximum day flows>10,000 gpd(37,854 Uday) • All systems with average primary treated effluent waste strength>200 mg/L BODS and 100 mg/L TSS • All systems with nitrogen discharge limits • All AX-Max systems;at least one ventilation assembly is required per two connected units(AX-Max units are typically designed with a built-in active vent system and one vent system per unit is preferred) Passive Ventilation Passive ventilation can be considered in AX20 or AX100 systems receiving primary-treated effluent of residential strength,with constituent con- centrations of<200 mg/L BODS and< 100 mg/L TSS and with design maximum day flows< 10,000 gpd (37,854 Uday)for AX100 systems and 4,000 gpd (15,140 Uday)for AX20 systems.For proper function, it is critical for air movement to be greater than 5 cubic feet per minute (cfm)for every 100 ft'of treatment area(0.002 m3/minute for every 9.3 m2). It is also critical to ensure that there is a clear path for airflow through the system if the system relies on passive ventilation. If these conditions cannot be met,active ventilation should be used. NDA-ATX-1 Orenco Systems®•800-348-9843•+1 541-459-4449•www.orenco.com Rev.8,©10/20 Page 18 of 38
