Ammonium and ortho-phosphate measurement with Liquiline System CA80AM and CA80PH

Aeration basin The analyzers save energy and costs. • The ammonium analyzer combined with an oxygen sensor allows accurate measurement of ammonium and oxygen concentrations and thus a precise, load-dependent control of the blowers. • The reliable orthophosphate measurement helps to optimize precipitant dosing. Water treatment In cooling cycles, the analyzers help to optimize phosphate dosing which is used to stabilize water hardness and for corrosion protection. Measuring ranges • Ammonium nitrogen 0 to 100 mg/l NH 4 -N • Orthophosphate phosphorus 0 to 10 mg/l PO4-P (blue method) 0.5 to 50 mg/l PO4-P (yellow method)

Liquiline System CA80AM and CA80PH analyzers use standardized colorimetric measuring principles to ensure direct comparability to lab results: • Indophenol blue method following ISO 7150-1, DIN 38406-5, GB 7181-87 for ammonium • Molybdenum blue method following DIN EN 1189 for low orthophosphate concentrations • Molybdate vanadate method (yellow method) for higher orthophosphate concentrations Typical applications The analyzers provide highly precise ammonium and phosphate analyses at all critical control points: Outlet The analyzers support compliance with limit values and appropriate documentation. Inlet The analyzers continuously monitor the incoming freight and allow prompt handling of peak loads.

Liquiline System CA80AM

The primary focus in wastewater treatment plants is to protect downstream waters. This is why the limit values for ammonium and orthophosphate are becoming stricter every year. Phosphate load is particularly important as phosphorus is the decisive factor for excessive algae and plant growth in water bodies.
