Conclusions

  1. 1.

    To intensify filtration we have tested polyhydroxyethylene specimens of various molecular weights; under laboratory conditions the use of this reagent enabled us to increase the filtration rate by a factor of 2–3 and to reduce the moisture content of the deposit by 4–5%.

     
  2. 2.

    We have proposed a relative coefficient of efficiency for comparing the action of different specimens of reagents.

     
  3. 3.

    It has been shown that the specific effect of polyhydroxyethylene increases with its molecular weight.

     
  4. 4.

    It has been established that PHE specimens, obtained in the catalytic system TIBA-DMGO (Nos. 162 and 105), are more active reagents during filtration than specimens of higher molecular weight (Nos. 156 and 155), obtained on AK catalyst.
