System Repair/Drainfield Rejuvenation, October 2013 | Editorial, Products that repair or rejuvenate failing systems can save homeowners substantial cost and frustration. Included here are additives, aerobic treatment units, jetters and pressure washers/sprayers designed to help installers get the most out of a struggling system.
Reason #1 – Highest Quality Effluent (As measured by BOD5 and TSS removal in ETV testing protocol and multiple state laboratory tests.)
Reason #2 – Excellent Denitrification Capability (As measured by Total Nitrogen Removal.)
Reason #3 – Consistent High-Level Treatment (Treatment fluctuation is minimized regardless of water use patterns.)
Reason #4 – Rapid Start-Up (Full treatment capability in less than 2 weeks.)
Reason #5 – Track Record (Hundreds of systems in the ground treating from 100-gpd to 76,000-gpd with strengths ranging from domestic levels to BOD5 / TSS measurements of over 2,500 mg/l.)
Reason #6 – Low Profile (Subsurface system access ports are just above ground level.)
Reason #7 – Minimal Odor (Vent through house stack or separate vent for pump station prevents odors.)
Reason #8 – Minimal Noise (No blower. Pumps are submerged. Air intake can be placed distant from house.)
Reason #9 – No Pumping or Owner Maintenance (Pump-back line prevents sludge build-up. No routine maintenance necessary like wash-down or addition of chemical tablets.)
Reason #10 – Competitive Pricing (All-inclusive price contains no surprises or hidden costs.)
Reason #11 – Reliable Product (Industry hardened PLC, high strength, non-corrosive components, minimal moving parts, self-cleaning media, highest quality, long-life pumps.)

Reason #13 – Dependable Service Team (Friendly SeptiTech service team always on call.)
Reason #14 – 2-Year Warranty (Includes parts, labor and annual inspection.)
Reason #15 – Reasonably-Priced Extended Warranty (Includes parts, labor and annual inspection.)
Reason #16 – Minimal Power Consumption (Demand based system requires power only upon inflow of wastewater. Efficient process control.)
Reason #17 – Managed Treatment Process (PLC customizes treatment, monitors pumps, floats, alarms and collects operating data.)
Reason #18 – Auto-dialer Capable (Standard on commercial units, available on residential units. Provides direct dial to SeptiTech technician in event of an alarm)
Reason #19 – Modem Capable (Standard on commercial units, available on residential units. Allows SeptiTech technicians to collect data, monitor operation and troubleshoot from a remote location.)
Reason #20 – CAD Availability (Technical drawings and system specifications on CD or FTP.)
Reason #21 – Plug & Play Technology (Depending on loading rates and flows, series or parallel units can be added.)
Reason #22 – Aggressive State Approvals (Most aggressive leach field reduction allowance in ME, VT, MA, NH, RI, OH and denitrification credit approval in Massachusetts.)
Reason #23 – Innovative Drip hose Approval and Installations (Installations in ME, NH and VT.)
Reason #24 – Built-in Discharge Pumps (No separate pump station required.)
Reason #25 – Easy Installation (No on-site assembly required of contractor, SeptiTech provided contractor installation manual and training.)
Reason #26 – Prompt Delivery to Site
Reason #27 – On Call Service (No charge telephone consultation available 7 days a week.)
Reason #28 – No Contractor Maintenance (Once properly installed, SeptiTech assumes service responsibility of unit.)
Reason #29 – EPA Environment Technology Innovation Award Winner
The SeptiTech advanced wastewater treatment system (AWTS) is currently used in over 100 denitrification sites. The system employs a recirculating fixed film bioreactor that utilizes both disc and bead media in a trickling filter system. The (AWTS) provides high level treatment of BOD, TSS and nitrogen removal.
The system recycles effluent through a raised media bed where a biofilm develops to remove organic load and convert nitrogen to inorganic nitrate and nitrite. Nitrified wastewater from the reservoir is recycled through the septic tank to biologically convert the nitrate and nitrite to nitrogen.
The aerobic trickling filter produces minimal solids. Any solids generated are gathered from the tank floor and pumped back to the septic tank inlet. Air is introduced to the recirculating flow by use of venturi nozzle. Our PLC logic provides control of the entire processor.
Treated effluent is micro-dosed from the processor tank to the soil absorption field or stream discharge using float controlled submersible discharge pump. Disinfection can be provided along the discharge line using a pressure UV sterilizer if needed.
The residential processor kits come in 4, 6, and 8 bedroom sizes and can be installed in either plastic or local concrete tanks. There are 4 basic commercial sized processors that are used for 1500 to 4500 gpd flows. Larger and non-residential flows can be treated by using multiple processors plumbed in series/parallel alignments. Hybrid designs of up to 100,000 gpd can also be engineered by SeptiTech.
SeptiTech’s treatment systems have been certified by NSF for conventional (NSF 40) and nitrogen (NSF 245) removal. SeptiTech’s system was tested under the USEPA’s Environmental Technology Verification (ETV) program.
Typical effluent from a SeptiTech system will have BOD <10 mg/l, TSS <10 mg/l and total-Nitrogen <15 mg/l. Startup of the SeptiTech processor is quite rapid and can yield target treatment concentrations within 4 to 6 weeks.
SeptiTech systems are designed to treat wastewater with minimal owner or operator oversight. In our commercial systems the PLC manages and monitors all system functions at all times. PLC information can be downloaded by modem and reviewed by experienced professionals at SeptiTech to assist with system adjustments and process changes.
