Low Temperature

Sludge Drying Technology Benefits

comparison of sludge drying technology

Environmentally Sound Wastewater Solutions

 

USA Sludge’s onsite low temperature sludge drying and condensate water recovery are odor free sludge treatment systems that are easy to operate and deliver cost effective, results.   This saves the end user valuable time and money, all while meeting and exceeding the EPA quality requirements for Class A bio-solids.

 

Equipment that a treatment plant operator does not have to fix and no longer operates
  1. Centrifuge
  2. Filter Press
  3. Digester Pumps and Boilers
  4. Odor Control Equipment
Reporting and Liability:

Tremendous reduction in liability and reporting to move to an EPA Class A EQ Bio-solids program.

 Eliminate Emissions Permits:

The most advanced energy efficient systems offer an odor free sludge treatment solution, requiring no odor control equipment or emissions permits.

Energy Used:

The dryers can be set up to use alternative energy such as gas, synthetic gas and solar panels.

Sludge Drying and Condensate Water Recovery

Recapture of filtrate water from the dewatering process, the sludge drying and condensate water recovery, all can be used as reclaimed water.   To dry one metric ton of solids from 20% to 80% solids, this will evaporate to 180 gallons or 1,494 lbs of clean condensate water.  The water quality from the condensate water is a distilled water, clean, mineral free and a Total Dissolved Solids (TDS) level of near zero and “is drinkable”.

Hauling Contracts

Elimination of hauling contracts which also means wear and tear on trucks and roads and reduced Carbon emission with reduction of burning Fossil Fuels for Transportation as sludge volume is decreased by 90%.

Eliminate Composting

By using state of the art, sludge drying technology, this eliminates composting by pumping sludge at .007% solids and have it dried to Class A EQ Bio-solids within 2 hours after pumping to our drying system without the need for digesting, while retaining more of the calorific value than composting piles.  All this and without 90 days of odor and decay and the release of Methane from composting. The “carbon footprint” of the 100 lbs. of Nitrogen in compost fertilizer is 6,403 lbs. of CO2.  That is 14.6 times as much as for synthetic urea fertilizer! It is the equivalent of burning 331 gallons of gasoline!

Beneficial Reuse:

The pellet produced by our sludge drying technology can be used for different things depending upon the kind of sludge being dried.

  1. Municipal Sludge to Fertilizer or Hydrogen Rich Energy Pellet to be burned.
  2. Milk Sludge (12,000 Btu per Pound) to Fertilizer or Animal Feed
  3. Winery Sludge to Fertilizer or Animal Feed
  4. Oil Tanker Sludge to energy pellet to be burned with coal
