Other Details

Ashtreat-CYNOF is a highly alkaline product used for neutralising content in effluent waste arising from electroplating shop and heat treatment shop.  By using Ashtreat-CYcyanide NOF  the cyanide level can be effectively brought down to 0.1 ppm which is below the acceptable limit of pollution control boards.  This treated effluent can thus be safely discharged into the sewage.

Advantages:-

1.      Ashtreat-CYNOF reacts with cyanides to form final compounds of carbon dioxide, nitrogen gases and non-hazardous sludge which can be safely and easily disposed without creating any pollution hazard.

2.      It reduces the cyanide level below 0.1 ppm of the effluent, which is well within the permissible limits.

3.      Ashtreat-CYNOF is highly alkaline, thus pH control is not required.

4.      Ashtreat-CYNOF is non toxic and causes no rise in temperature during treatment.

Directions:-

1.      Check the cyanide content of the waste effluent.

2.      In case of waste effluents from Electroplating shop, pH value of the solution should be checked first.  If it is found acidic then the same should be brought to pH 11.5.  This is important.

3.      Then calculated amount of Ashtreat-CYNOF is added slowly and continuously depending on the cyanide content in the effluent. Stirring or Aeration will help to reduce treatment time.

4.      Treatment time should be minimum 120 minutes, before discharging effluent in sewage.

5.      After completion of above treatment, titration of 10 ml of treated effluent waste should be carried out to ensure that cyanide content is well within permissible limits.

Notes:-

1.      Lime should not be added to raise the pH of the effluent as this may give rise to heavy sludge formation which can trap cyanide radicals. This living cyanide will go undetected during testing and unattacked during treatment and will go into the sewage along with treated effluent.

2.      To avoid evolution of toxic fumes, the pH of effluent should be maintained above 11.5, and the temperature below 30°C, at all times.
