C3. Filter through activated carbon. At least 950 g of granular carbon per 100 Liters of solution (8 pounds per 100 gallons) should be used. Since most carbolators will not hold that much carbon, several charges of carbon will be necessary. The solution should be turned over 2ormore times for each charge. The total timethat any one
charge of carbon is exposed to the bath should not exceed 8 hours.
C4. Verify complete carbon treatment by full matte Hull cell. The resultant hull cell should
