Struvite Treatment

1,988 views

Published on

Anaerobic sludge digestion in wastewater treatment plants releases ammonium, magnesium and phosphate. The presence of these components can form struvite, which can lead to great inefficiency within the plant due to scale on lines and belts, in centrifuges and pumps, clogging of system pipes and other equipment including the anaerobic digester itself.
The chemical cleaning is now favoured as it can prevent and remove struvite with minimal downtime. BASF Water Chemicals offers you Antiprex® AD 1020 XP and Antiprex® MSA, which show excellent performance in the prevention and treatment of struvite issues in wastewater treatment plants.

Struvite Treatment

  1. 1. November 2017 Struvite Treatment
  2. 2. Water Chemicals Struvite is a challenge in municipal and industrial wastewater treatment plants November 2017 2 Struvite or MAP (Magnesium, Ammonium and Phosphate) is a phosphate based mineral (NH4MgPO4·6H2O) which can be defined by the following characteristics: What is struvite? Sparingly soluble in neutral and alkaline conditions Readily soluble in acidic conditions Very hard scale Sensitive to operational conditions (e.g. pH, conductivity, T°, etc.)
  3. 3. Water Chemicals Struvite formation in pipes and process equipment is reducing plant efficiency Anaerobic sludge digestion in municipal and industrial wastewater treatment plants releases ammonium, magnesium and phosphate. The presence of these components can form struvite, which can lead to great inefficiency within the wastewater treatment plant due to scale formation on lines and belts, in centrifuges and pumps, clogging of system pipes and other equipment including the anaerobic digester itself. Scale in pipelines and on process equipment Problem November 2017 3
  4. 4. Water Chemicals Struvite is a very hard scale and cannot easily be removed by physical treatment November 2017 There have been a few physical options to solve this issue:  Replacing affected pipes  Using a hydro-jet  Using a mechanical grinder Solution Many tubes and pipes can be underground and physical treatment causes significant downtime and cost Chemical cleaning prevents and removes struvite effectively with minimal downtime and cost Preventive and curative struvite treatment with:  Antiprex® AD 1020 XP  Antiprex® MSA 4
  5. 5. Water Chemicals Additives with visible performance in preventive and curative struvite treatment 5 Antiprex® MSA Curative Struvite Treatment Antiprex® AD 1020 XP Preventive Struvite Treatment Efficient antiscalant for the prevention of scale deposits including calcium carbonate, calcium sulphate, strontium sulphate and barium sulphate in water systems:  Excellent in aqueous media  Efficient antiscalant to prevent struvite precipitation in WWTP* Antiprex® MSA (Methane Sulphonic Acid) is a strong odorless organic acid with the highest purity in the industry:  Fast acting  Effective cleaner  Safe to-be handled  Readily biodegradable November 2017 without preventive treatment with Antiprex® AD 1020 XP without curative treatment with Antiprex® MSA
