  • Ultra-small VOLUTE Dewatering Press ES-051 (Ukraine (1))

    In the year of 2004 in Ukraine, there was no compact sludge dewatering equipment suitable for small-scale wastewater treatment facilities like septic tanks. As for septic tanks, it had been common that sludge was disposed by tanker truck and sent to sludge dewatering facilities for post treatment. For that reason, the annual sludge disposal cost was extremely high, which had been a major issue ...

  • Oil Field Sludge Dewatering

    An oil field contract dewatering company was unable to dewater the oily/water/solids from several oil field storage tanks using conventional coagulants/flocculants. The swings in solids loading and oil content made it very difficult to control the correct dosage rate as conventional chemistry has a very tight tolerance to maintain a dewaterable floc. The result was an ongoing blinding problem for ...

  • Comparison of centrifuge and belt press for compressible digested sludge after thermal hydrolysis

    Abstract Historically it has been shown on many projects that centrifuges can outperform belt presses in dewatering digested sludge. However, results from a number of projects where sludege has been treated before digestion with Cambi thermal hydrolysis process (THP) hase shown good results for belt press dewatering - generally greater than 30% DS. The authors propose that the main mechanism in ...
