UV analysis-the reagent-free alternative: NITRATAX plus sc

NITRATAX plus sc Precise, self-cleaning UV nitrate process probe, 1 mm

Product ID: LXV417.99.10001

Reagent-free method. Multiple beam absorption photometer with a flash lamp, turbidity compensation through reference measurement. Lowered directly into the sample stream (flow-through unit optional).

UV absorption method-proven, continuous, and precise
Eliminates reagents, sampling, and sample conditioning
Self-cleaning probe
Measurement in activated sludge or in water
Life-long factory calibration

Stainless steel probe. UV beams are projected across a gap for immediate measurement of the nitrate content in water, wastewater and activated sludge. The measuring windows are cleaned by a wiper. Evaluation by SC controller. The simple mounting and easy handling of the probe is guaranteed by a specially designed tank rim mounting hardware. In order to place the controller near the probe, the tank rim mounting hardware for sc controller should be used. The through-flow variant is used wherever submersible installation is not possible for construction related reasons or the medium makes it necessary to measure a filtered sample (very high TS contents, sewage treatment plant inlet, etc.).

APPLICATION NITRATAX plus sc Adjustment of simultaneous nitrification /denitrification by nitrate concentration With simultaneous nitrification / denitrification, organic carbon and ammonium-bound and nitrate-bound nitrogen are eliminated in a single tank. Either a circulating tank or a tank that can be considered to mix the medium thoroughly is used. Aeration can be regulated as a function of the ammonium-bound or nitrate-bound nitrogen. In operational practice, regulation by nitrate-bound nitrogen has been found to be the most favourable. It uses less aeration energy, and the risk of floating sludge in the final settling tank is low.	English, English	510 KB	PDF	Link	2004-08-19
Cost savings with the latest control techology in Ladbergen The WWTP of Ladbergen (Germany) is one of the top-performing plants of the region, although the inlet conditions are extremely difficult with a COD up to 3.000 mg/l. With significant rebuildings, process instruments by HACH LANGE and the modern control system Opti-Nox by KLEINE (engineering office in Germany) they achieved this position. In future they are going to save energy and further reduce wastewater fees.

Optimal nutrient ratios for wastewater treatment Author: Michael Winkler. For observing the legal requirements of treated wastewater, the operator of a wwtp has to manage the wastewater treatment process thoroughly to avoid exceeding the limit values. Among physical and chemical procedures the effluent treatment is based on the biological treatment by the microorganisms of the activated sludge. Therefore good knowledge of nutrient need and composition of the activated sludge is very important for operating at full capacity. Causes, consequences and counteractive measures for unfavourable nutrient ratio are described in this report; 8 pages	English, English	972 KB	PDF	Link	2013-01-02

Telemetry for the highest level of plant reliability Author: Uwe Karg, Diplom-Ingenieur, chemistry, Application process measurement technology, HACH LANGE. Reliability is a main goal for control processes which have to reduce operating costs or ensure compliance with limit values. WWTP in Radolfzell (40.000 PE) at the Bodensee (Lake Constance) fullfil both requirements. Process measuring instruments supply the control system continuously with readings and signal their operational readiness by means of telemetry. Non-compliance with the limit values has been reduced significantly and the savings in added carbon amount to up to € 8,000 each year. 4 pages	English, English	657 KB	PDF	Link	2008-04-22
