ECO Versus Conventional Biological Systems

Traditional Biological Systems

The conventional method of wastewater treatment is a biological process using aeration followed by gravity settling. The process uses large tanks or lagoons and requires large areas of land. Traditional methods of treatment have remained relatively unchanged for decades.   Some of the disadvantages are:


  • Capital and maintenance intensive
  • High operating and energy costs  
  • Land intensive  
  • Requires long lead times to build
  • Detention times are lengthy.  The time require to process the wastewater takes days
  • Generates greenhouse gases harmful to the environment
  • Generates foul smells that propagate for miles
  • Requires multiple employees to operate
  • Expansion in capacity is a difficult and long process
  • Leaks can be devastating
  • Water purification quality is not adjustable

The Eco System

The Eco System is a significant improvement over the existing technology in conventional municipal wastewater treatment facilities.   Eco System has lower capital and operating costs, smaller physical footprint, is modular, scalable, can be installed with minimal lead time and produces a higher purity of water than current technology.  Some of the advantages are:

  • Lower capital and operating costs
  • Lower maintenance and servicing costs
  • Smaller physical footprint
  • Easily maintained and serviced
  • One technician can operate the entire system
  • Minimal moving parts for long lasting and more reliable components
  • The system is modular which can easily be adjusted to changing needs
  • The system is scalable where additions to the system can increase capacity immediately
  • Minimal lead times since modules are built offsite
  • Generates no greenhouse gases
  • No foul smells
  • No leaks
  • Water quality is adjustable based on membrane selection

ECO VERSUS DAF SYSTEMS

DAF Systems

Typical DAF (Dissolved Air Flotation) systems are massive, expensive, highly susceptible to failures, very labor intensive, and highly inefficient.  Some of the disadvantages of DAF systems are:


  • DAFs use external air pumps to introduce air into the system
  • More moving parts increase the probability of failures and decreases the reliability of the air injection system
  • Higher energy demand due to higher operating power requirements
  • Requires a separate pressurized system
  • Requires separate water sources independent of the wastewater stream
  • Due to the pressurized systems, tanks need to be metallic, which are heavy and susceptible to corrosion 
  • More controls needed to process these separate air pumps, pressurized systems, and water sources
  • Due to the complexity of the air injection systems, systems tend to only have one air injection location

Eco Separation Module

The Separation Module of the The Eco System shown here is a highly efficient, low cost, and low maintenance alternative to traditional DAF systems.  The Eco System uses a Venturi air injector which is a simple static device with no moving parts to introduce micro air bubbles into the system.   Some of the advantages of The Eco System are:

  • No external devices or systems are needed to introduce air into the system.  The Venturi air injector is an internal component
  • Venturi air injectors rely on the geometry of the design to change the pressure and generate suction of air into the system.
  • No energy demand or power consumption.  The injectors use the flow of water through it to operate
  • No separate water sources needed.  The injectors introduce air using the same wastewater that is being processed
  • The lack of moving parts makes these systems long lasting and highly reliable
  • Less labor intensive
  • Venturi injectors can be easily moved different locations within the system
  • Multiple air injection locations.  This allows for our proprietary processes that produce the best rise rates and quickest processing times in the industry
  • The tanks are lightweight and not susceptible to corrosion
  • More efficient and faster processing time
  • Easily maintained and serviced
  • Less controls are needed
  • Smaller tanks process more wastewater than DAF systems
