Process Analysis
Outstanding Process Measurement Technology and Samplers Reliable, stable processes are essential for cost effective process measurement. This is true of both drinking-water and wastewater treatment systems. With versatile probes and integrated digital controller networks, HACH LANGE sets the standards for excellent process-measurement technology. With reliable monitoring of all relevant parameters, for every user requirement, this ensures accurate performance and cuts in operating costs. The SC 1000 Network - One Controller Measures all! The standard layout for nearly all instrumentation is one sensor per controller, this means high investment costs. In contrast, modern sensors calculate their measured values themselves and can be used with standard controllers. The advantages are obvious. Any desired combination of sensors can be connected to just one controller. For spare parts administration is also much easier and less costly. Advantages include: Digital controller for up to 8 digital probes and analyzers Cost effective, can be upgraded any time Integration of existing measurement signals Comprehensive control and calculation functions Simple operation with portable touch screen Remote data transmission and remote control by SMS More About Advantages of SC network Comprehensive solutions for turbidity, solids, particles and sludgeDrinking water treatment, industrial water treatment, wastewater treatment, demand special attention. Clear water requires consistent filter management to ensure operational reliability. Processes in which sludge is generated also need to be monitored continuously to ensure that everything runs smoothly and the costs of sludge dewatering and disposal are firmly under control. HACH LANGE have a wide range of solutions for turbidity, solids, particles and sludge. ARTI particle counter - For effective monitoring of drinking water FILTERTRAK 660 sc - Online-Laser-Turbidity-Sensor for ultra-clear fluids 1720E - White light turbidity sensor for low-medium turbidity Ultraturb plus sc - Top class infrared turbidity probe SOLITAX sc - Turbidity probe family for turbidity from lowest to highest concentration SURFACE SCATTER sc Turbidity Probe - Essential for tough industrial applications SONATAX sc process probe - The superior way of measuring sludge levels pH, Conductivity, Oxygen: Reliable Monitoring for all Applications The reliable monitoring of pH, oxygen and conductivity is the basis for efficient process control in many applications. The many and varied fields in which these parameters are used require special solutions, which the extensive HACH LANGE range of products can provide. The continuous measurement of dissolved oxygen is a key area, with exciting innovations. It enables savings to be made in the control of aeration processes, e.g. in sewage treatment plants. Digital sensors for the measurement of pH, redox, conductivity LDO - Luminiscent Disolved Oxygen sensor Complete Solution For Nutrient Parameters: Ammonium, nitrate and phosphate measurement is crucial in wastewater treatment. In municipal and industrial sewage treatment plants, the reliable measurement of these variables is the basis for all control concepts. The nutrient parameters also play a central role in the monitoring of surface waters and in drinking water treatment plants. HACH LANGE has the solution for every user requirement profile, with process probes and analyzers can be installed on-site and in-house.

It is impossible to analyse all of them individually. The organic load of such streams is therefore generally determined by measuring sum parameters such as COD, BOD5, TOC and SAC254. Two parameters are especially suitable for the continuous monitoring of organic load: TOC (conforms with EN 1484) and SAC (conforms with DIN 38404 C3). ASTROTOC - Continuous TOC measurement ideal for industrial conditions TOCTAX - Continuous TOC measurement - ideal for municipal wastewater UVAS plus sc - probe for dissolved organic content Fully Automatic Stationary and Portable Samplers HACH LANGE’s extensive range of samplers includes portable and stationary systems using pressure/vacuum or peristaltic technology.
