HUBER SeptageTreat Solution
HUBER SeptageTreat Solution for the treatment and reuse of septic sludge
Sludge from septic tanks is odorous, offensive and corrosive. It often contains grit, gravel and stones, as well as all kinds of objects that can pass through toilets.
Where possible, septic sludge is hauled to a large central wastewater treatment plant where it is screened (we recommend our ROTAMAT® Ro 3 septage receiving stations) before it is blended into raw wastewater or sewage sludge.
Because sufficiently large and well equipped treatment plants are usually not available in developing and emerging countries, the septic sludge is often hauled to far away deserts or wastelands. Due to its open anaerobic degradation methane is released. Methane is a 23 times stronger greenhouse gas than carbon dioxide. Methane emissions cause global warming.
Our SeptageTreat System is the best solution for this problem. The collected septic sludge is screened, degritted and dewatered. To prevent odour nuisance and corrosion, the entire treatment is done in enclosed stainless steel machines.
The removed screenings are washed, dewatered, compacted and bagged. They are disposed of as solid waste. The removed grit can be washed and reused as a construction material, e.g. for road bedding.
The filtrate from sludge dewatering is treated in one of our compact membrane bio-reactor (MBR) systems. Since it contains valuable nutrients the treated effluent should be reused for irrigation.
The dewatered sludge cake is then aerobically composted in simple windrows on site. The biosolids are reused for land application and soil improvement. They contain valuable nutrients and much organic carbon.
