Electro-Coagulation

Carbon Dioxide Control of Alkalinity


WT Reactions Comparison

Ferric chloride positive charge

Cationic polymers positive charge

Metal plates are charged & sacrifice a (+) metal ion

The metal ion is normally Ferric or Aluminum

• Colloids normally carry a negative charge

• Dosage rate is related to contaminant load

•The metal ion cause the destabilization of suspended particles•The destabilization results in several forms of coagulation (compression, adsorption, sweep & bridging) •The consumption of electrical energy is inversely proportional to the conductivity

Electrical-CoagulationChemical Coagulation


WT Advanced Treatment Technologies

Particle destabilization is essential

Particle sweeping is essential

Particle agglomeration is essential

EC Technology is based on Faraday’s Laws of Electrolysis


WT Four Main Reaction Principles

• Electro-flotation !!!!!!!! Production of micro bubbles supporting sweep aggregation

of particles

• Electro-flocculation Production of flocculating agents that promote bridging

and coalescence to remove colloids

• Electro-coagulation Production of sacrificial ions to promote destabilization and

charge neutralization and the promotion of oxidation

• Electro-oxidation Via the production of hydroxyl radicals

Enforcement of Regulations is changing

&

Technology is getting better

Be

Involved


WT “The 2nd Key”

Clear

Permit

Language


WT “The new rules”

•Temporary Erosion Control Plans

•That detail the size, frequency and volume of rainfall events as a baseline to

design and size

stormwater treatment systems



Expectations-

numeric requirements!!!!!!!!!

new digital control systems allow protection for the contractor, the State and the environment

Subjective rules put all of us at risk!!



Water Characteristics –

•Require the treatment system designers to address the site water characteristics;

•high pH due to lime treatment,

•low conductivity,

•high colloidal clays

•Backup emergency plans

•Toxicity management



Setup reciprocal agreements

with other States

Treatment systems need safeguards to protect the environment & the user

calibration, toxicity controls

operation logs


WT The new message

Where Sediment ends – BMP’s

Turbidity begins - AT

Sediment is > 0.45 microns

Turbidity is < 0.45 microns


WT Ask yourself the questions

What Performance is required ?The State needs to define the requirements

What are the risks?

Toxicity and Litigation

Mobilization & Treatment Costs ?The market place will sort out cost of treatment

Safe ?
