Shifting to New Technologyin an Old Regulatory World

Two Controlling Factors in Technology Advance

The S-Curve PhenomenaThe Scientific Hubris Conundrum

The S-Curve

Waste Water Treatment Technology Advance

Primary Treatment Removal Efficiency

90-95% settleable solids 40-60% suspended solids 30-40% Biological Oxygen Demand 18% Nutrients removal

Secondary Treatment Removal Efficiency

70% Biological Oxygen Demand 75% Chemical Oxygen Demand 1% Nutrients removal

Tertiary Treatment Removal Efficiency

30 – 75% Nutrients removal Massively Expensive Difficult to operate

Cost-Efficient Alternatives to Tertiary Treatment

Will require Reassessment of the Pollution Control Mentality

EPA Standards reflect a static assumption about “Assimilative Capacity”

It is possible to increase assimilative capacity

The Alternative to Tertiary Treatment

“Rather than considering treatment procedures which remove the nutrients nitrogen and phosphorus from a sewage discharge

July 31, 1980

one might consider the addition, if feasible, of silica in quantity at the discharge site

to alter the receiving waters to a diatom population and a consequent fertile and productive region.”

To Accomplish a Paradigm Shift to a New Technology

Research, test and demand use of the new paradigm
