In 2007 Inbar Committee regulations (2005) will come into force, stipulating that sewage sludge should be treated to Class A standard.
There are advanced technologies for sludge stabilization to Class A standard that are practiced worldwide but have not yet been applied in Israel.

  Introducing new technologies to the Israeli market, after their adaptation to local conditions, widens the choice of available technologies that best fits the economic and technical needs of each plant.

  In cooperation with international design companies, Triple-T acts to implement (on a BOT basis) energy-saving, low-cost technologies, which turn the sludge into an environmentally friendly product. All technologies are approved by the EPA and widely implemented throughout the U.S. and Europe. Among these technologies:

     ·     Wetland – based on biological degradation processes occurring
           in an ecological system that combines saturated beds and
           vegetation. Bacteria found in the roots zone degrade the
           pollutants into stable compounds.

     ·     Alkali Stabilization – adding an Alkali supplement (such as
           lime) to the sludge that triggers a chemical reaction that raises
           the pH and the temperature of the mixture and results in the
           purification of the sludge. The maintenance of such a system in
           very simple and does not require skilled manpower.

     ·     Drying in a greenhouse – In addition to using solar energy, it
           is possible to use aeration and utilize a mechanical device to turn
           over the sludge so that a larger surface area will be exposed to
           the radiation and the aeration.
