ExtremeSTP Cold Climate Sewage Treatment Plants

ExtremeSTP Design, Installation, Operation & Maintenance Overview

Unique Design

ExtremeSTPs (U.S. Patent 6,482,322; Canadian Patent 2,318,710) combine a unique design with easy installation, simple operation, and minimal maintenance. They can be sized to serve any facility, whether a cabin, large home, ski resort, construction camp, exploration camp, lodge, hotel, or an entire community. Several standard residential sizes are available to suit your needs, but we can customize each one to suit your site.

At the heart of every ExtremeSTP is a Fixed Activated Sludge Treatment (FAST®) insert manufactured by Bio-Microbics, Inc. FAST® treatment technology is ideally suited to "packaging" for use in cold climates. By applying some simple but vital arctic engineering, we developed a system that is suitable for use in any cold climate.

Features include:

• They work on permafrost and other areas with poor soil conditions (almost anywhere)
  
• They operate at -60ºF (-51ºC) even when installed above ground
  
• They are built in one multi-compartment, super-insulated tank that maintains an optimum environment for biological growth
  
• Bacteria attach themselves to a growth medium and become "fixed", thus avoiding the need for the clarifier found in conventional extended aeration sewage treatment plants
  
• The only moving part is the air blower
  
• Heat tape is not necessary for normal operation, even at -60ºF
  
• UV (ultraviolet) disinfection is standard on above ground units
  
• An automatic dosing siphon (with no moving parts) eliminates icing at the point of discharge
  
• They treat all residential wastewater including "blackwater" and "graywater" from a house equipped with normal flush fixtures, hence no special plumbing is required
  
• They can be used temporarily beside a failed septic system to treat sewage until permanent repairs can be made
  
• An optional data logger and remote monitoring system is available
  
• An optional thermosyphon is available to help keep the permafrost frozen underneath the system
  

• Above ground models can be installed totally above or partially below ground
  
• Above ground models can be installed at any time of year
  
• Above ground models are easy to relocate
  
• No exterior shelter is required
  
• Below ground models are designed for up to 4 feet of cover, or they can be skid-mounted for above ground seasonal use or year-around use in a building
  
• For above ground models, little or no excavation is required - simply set the ExtremeSTP in place and connect the inlet and outlet pipes and electrical power
  
• In some jurisdictions, approvals may be obtained for:
  
  • Reduced leach field size
  • Reduced separation to ground water
    
  • Use on smaller lots
    
  • Surface discharge onto land
    
  • Surface discharge into water

• No complex instructions or life style adjustments - just avoid excessive use of chemicals that destroy bacteria
  
• No daily, weekly, or monthly attention needed except to check that the blower is working and alarms are off
  
• Effluent is clear, essentially odorless, and oxygen-rich and in permafrost areas is typically discharged on top of the ground in an area of undisturbed natural vegetative mat
  
• Effluent meets the surface discharge standard of 30/30/200 (30 mg/L BOD5 {biological oxygen demand}, 30 mg/L TSS {total suspended solids}, 200 cfu/100 ml {fecal coliform per 100 ml}) and often meets 10/10
  
• The oxygen-rich effluent from an ExtremeSTP can help rejuvenate a failed soil absorption system
  
• The blower timer can be adjusted for various operating conditions (if so equipped)
  
• The FAST® process can achieve 70 percent removal of nitrogen
  

• Clean the UV bulb every 3 to 4 months
  
• Clean the fresh air filter every 3 to 4 months
  
• Check and replace the return air filter every 3 to 4 months
  
• Clean the blower housing every 3 to 4 months
  
• Replace the UV bulb every 1 to 2 years
  
• Pump sludge from the unit every 2 to 5 years
