Because all of its components are designed to work together, ProPak reduces installation lime and errors. The ProPak pump vault includes a Biotube filter cartridge for filtering solids from the effluent pumped out of the lank's clear zone. Filtering solids from the effluent reduces loading and clogging of downstream components. ln lurn, this extends the life of drainfields, secondary ireatment sys- tems, and other downstream components. When an Orenco Biotube ProPak pumping system is used in a properly sized, slructurally sound, water- tight septic/dosing tank, it can be reliably expected to reduce Total Suspended Solids [lSS) by an average of more than 60% This document provides Orenco's design recommendations for using the ProPak pumping system to pump out of a single septic/dosing tank Before using these design recommendations, please verify that they will meel or exceed applicable regulalory requirements in your area. Specific areas for consideration when designing with the ProPak are lank reserve volume, tank minimum liquid level, and minimum dose volume. Figure 1 shows a typical single{amily system with a ProPak in a single-compartment septic/dosing tank. Raw sewage enters the septic/dosing tank and separates into three distinct zones: a scum layer, a sludge laye¡ and a clear zone. The ProPak pump package draws effluent from the clear zone and filters it before pumping it to a drainfield, secondary trealment system, or other downstream termination point. ln effect, the ProPak effectively acts as a separate dosing tank inside of the septic tank; eliminating the need for additional dosing lankage outside of the septic tank, An 0renco ProPak ensures high quality effluent by baffling and screening large solids that could othen¡rise escape the septic/dosing tank. The Biotube Pump Vault's closed bottom and vertical inlet holes help to retain sludge, scum, and other gross solids in the tank - even when biologi- cal agitation (bulking) 0f the tank's contents occurs. Thus, Orenco's Biotube Pump Vault Technology provides sludge, scum and gas baffling. 1{DA-BPP-I Rev.2.0, O 07/17 Page 1 of 6 Seplic/dosing hnk Seurn tayer @ Clearzone -)o+ Figure 1.

Pumping System Requirements: Septic Tank Because septic lanla provide the initial treatment for any septic system, ¡t is criticalthat lhe septic/dosing tanks used with ProPak pumping systems are properly designed, structurally sound, and watertight. The ProPak can pump effluent from a single- or dual-compartment septic/dosing tank. ProPak Pumping SysÌems are designed to take in effluent from the clear zone of the septic/dosing tank, Care must be taken lhat the ProPak vault's inlet holes are posilioned af 70Vo (t.1 07d of the minimum liquid level in lhe tank - approximately al the center of the clear zone - to assure that effluent from the clear zone is being filtered. For punp flows less than 40 gallons per minute (< 2.52liters per second): Single-compartment septic/dosing tanks can be used. The drawdown in a septic/dosing tank with a single compartment should also be minimized to ensure that sufficient retention and settling t¡me are provided in the lank; this equates to sustaining a liquid volume of about 90% of tank capacity.

Additionally, the liquid level in dual-compartment septic tanta should be kept as high as pos- sible to maintain effluent quality. Scum and sludge layers develop in the secondary compartment - though less rapidly üan in the primary comparl- ment - s0 it is best to maintain surge and reserve volumes by using a dual-compartment tank with a shared liquid level. (See Figure 3.) Pumping System Settings: Pump Vault Placement The inlet holes in the Biotube Pump Vault should be localed at about 70olo (* 10%) of the distance up from the the bottom of lhe tank to the low- est operating liquid level ("0ff" float or "Timer off" float). (See Figures 4 and 5,) This location allows lhe ProPak to draw effluent from the middle of the clear zone in the tank. As the accumulation of scum and sludge occurs in the tank, the location of the inlet holes ensures thai the highest quality effluent is being filtered and lransported out of the septic/dosing tank. Pumping System Settings: Float S¡¡vitch #ttings Several factors affect the operation 0f the system and the location of the float switches. These factors may include, but aren't limited io, dose method; downstream componenls; and local, municipal, county, 0r state regulations. lnformation provided in this section is intended to be used as a guideline. The portion of the septic/dosing tank between the level 0f the 'Off" Íloal and the level of the "0n" float (for demand-dose systems) 0r the "High level alarm" float (for timed-dose systems) is called the operating zone. Demand-dose systems are typically used to pump effluent to a gravity drainfield or downstream treatment system. For demand-dose systems, the operating zone should be as small as possible. The small operat- ing zone allows more scum and sludge to be stored in the lank. lt also minimizes the disturbance of the scum layer during pumping cycles. The minimum achievable operating zone for a ProPak system is 2 inches (50 mm). This is the closest that the "0n" and an "Off" floals can be physi- cally placed to one another, Timed-dose systems are typically used to pump effluent to soil, sand, and media filters for additional treatment. For timed-dose syslems, the operating zone should be sized as small as possible while allowing for 24 hours' worth of estimated daily flow storage. To balance the need for a small operating zone with the need for flow storage capacity, we recom- mend using single-compartment tanK or tanks with shared liquid levels for limed-dose applications. Float settings for both types of dosing systems also need to account for reserve volume in the septicidosing tank. The reserve volume is the por- tion of the tank from the soffit 0f the tank to the invert of the tank inlet ("High level alarm" float setting). Reserve volumes should be capable of storing 24-48 hours', of estimated daily flows. Demand-dose float settings : Float settings for demand-dose ProPak applications are typically set to maximize the volume in the septic/dosing tank by utilizing a small operat- ing zone. Figure 4 shows general guidelines for float placement. Standard settings for demand-dose are as follows ... ¡ "High level alarm" float:At the invert of the inlet of seplic/dosing tank, as measured from the outside top 0fthe tank. r "0n" float: 2 inches (50 mm) below the high level alarm floal ¡ "Off" float: 2-4 inches (50-100 mm) below the "0n" float. The amount of space between the "0n" and "0ff" float will determine dose volume. N|TE: The on/off function may be controlled by one float. ln this case, dose volume will be constrained by the dnwdown of the "0n/0ff" float, oo o -o -o -ø Figure 4.

A design parameter of 50 gpcd (190 Lcpd) is commonly used in determining estimated flows from a dwelling. Estimated flows are determined by multiplying the number of occupants in the dwelling by 50 gpcd (1 90 Lcpd). Figure 5 shows general guidelines for float placement. ¡ "Hiqh level alarm/ovenide" float: At the invert of the inlet in the septic/dosing tank, as measured from the outside lop 0f the tank. The "High level alarm" function is combined with the "Override" function. (Some jurisdictions require separate floats for high level alarm and override functions. When a single-func- tion float switch is used for the "Override" funclion, it is typically set al 2 inches or 50 mm below the "High level alarm" float.) ¡ "Timer off" float; This float is set at a distance below the "High level alarm" float or the "Override" floal, equal to the estimated flows for the system. (Example: a home with -person occu- pancy would be set for estimated flows of 200 gallons per day (757 liters per day) or 50 gpcd x 4 (190 Lcpd x 4). "Redundant off" float settings: A "Redundant off" float may be used with both demand-dose and timed- dose systems. The "Redundant off" floal is placed 2-3 inches below the "0ff" float in demand-dose systems, or fte "Timer off" float in limed- dose systems. D ra i nf i el d Gonsi d erati ons When designing the pump system for any type of low-pressure dispersal system (sand filters, pressure drainfields, mounds, etc.), it is important t0 note that the best design practices address not only the issue of supplying frequeni, small doses for dispersal, but also equal distribution. Equal dis- tribution of frequent, small doses maintains the oxygen supply fo microbes and promotes the best possible aerobic treatment. Using small-diameter laterals (typically 1-inch) and orifices (typically 1/a-inch) helps to ensure equal distribution of effluent in a dispersal system. Package Selection All ProPak pump packages are available for both demand-dose and timed-dose applications, with 15, 20, 30, and 50 gpm (0.95-, 1.6-, 2.5-, and 4,1 L/sec) flow options. There are two basic packages: 1 . Demand-dose - The BPP1SDD accommodates flows up lo 20 gpm (1.3 L/sec) and is used to pump to gravity drainfields (distribution boxes, hydro- splitters, etc.). BPP20DD, BPP3ODD and BPPSODD systems are available for demand-dæe applications that require fl0w rates greater than 20 gpm. 2, Timed-dose - The BPP30TDD accommodates flows up to 40 gpm (2.5 L/sec) and can be used for pumping to a pressurized final dispersal system (drainfÍeld, secondary treatment system, etc.). BPP3OTDD systems are available for timed-dose applications for small pressurized dispersal systems (e,g. sand filters, mounds). BPPS0TDD systems are available for timed-dose applications that require flows between 40-65 gpm (2.5-4.1 L/sec), such as large pressurized drainfields or mounds. Design Tools The ProPak Design Aid CD-ROM includes a ProPak Selecl'" software program that allows system designers and specifiers to select the correct ProPak package for their application. When project-specific parameters are entered intolhe appropriate f¡elds in ProPak Select, minimum pump requirements are automatically calculated (e.9, lotal dynamic head and flow rate) and the appropriate ProPak model is selected for your application.
