Increasingly stringent regulations and consent requirements are continually being put in place to maximise compliance by industrial companies – and minimise harmful discharges to the environment.
The typical consent parameters include pH, temperature, organic load and suspended solids. Any breach of these consent limits can prove costly to offending companies. And, with the Environmental Liability Directive that came into force on 1 March 2009, and updated in 2015, the ‘polluter pays’ principle holds those responsible for causing damage liable for remedying it. As a consequence, the need for accurate, effective and traceable measurement has never been so critical.
At the very least, installing an on-site autosampler to sample your trade effluent stream(s) will ensure that you always have a representative sample to give to the trade effluent officer. Furthermore, continuous monitoring of your key consent parameters, along with remote alarm triggering, ensures that you are always in the picture and able to react quickly.
Endress+Hauser’s Liquiline platform with Ethernet connection means that you can even view your consent measurements from home or the office – and be alerted immediately in event of an incident. We will even work with you to design a bespoke effluent monitoring and control system to give you complete automation and control.
Simple sampling Our Liquistation CSF48 stationary sampler and the portable Liquiport 2010 CSP44 offer the best in simple yet reliable sampling.
Both these autosamplers carry Environment Agency mCERTS validation, which proves their reliability and functionality. The core principle of our analysis platform is ensuring simplicity via a common interface for Liquiline instruments. This platform concept also makes it possible to easily extend the autosamplers into measuring stations, enabling the measurement of traditional parameters like pH and turbidity without the need for additional transmitters.
Collecting/obtaining a representative sample is the first and most important step in any liquid analysis. Basic to advanced modes of operation can be programmed to achieve this representative sample. Our autosamplers can be fitted with an optional cooling system to ensure that the samples are not exposed to any fluctuations in temperature and therefore cannot be affected by any biological activity that changes the sample integrity.
Continuous monitoring of consent parameters
Memosens digital sensors and Liquiline multi-parameter transmitters are a winning team when it comes to the reliable measurement of consent parameters. Backed by a range of optical sensors and analysers covering COD and TOC, we really can’t be beaten!
The use of a simple pH loop as part of a dosing system ensures that your effluent is within consent parameters and eliminates the possibility of costly fines, not to mention hefty billing charges. For example, where post-CIP effluent may be above the typical consent maximum of pH10, appropriate monitoring with our Memosens pH and effluent neutralisation prior to discharge ensures compliance.
Furthermore, using Memosens technology offers the added benefits of enabling maintenance and calibration away from the measuring point. Pre-calibrated sensors can be easily exchanged, thus minimising both maintenance effort and downtime. Memosens sensors use an inductive non-contact signal that eliminates all of the problems of traditional analogue signals, such as moisture ingress that leads to measurement instability or complete loss of data. Better still, the storage of calibration and process data in the Memosens sensor head enables simple data retrieval using the Liquiline CM44 or CM42 transmitters, making it extremely useful for predictive maintenance.
Our Liquiline CM44 digital platform enables up to eight measurements in a single device in any parameter combination. Expansion is possible at any time by simply adding modules and connecting them with Memosens technology. It covers all of your effluent monitoring parameters including pH, turbidity/suspended solids, oxygen, conductivity, nitrate and SAC, and ion-selective electrodes.
The sensors are now complimented by a new range of online analysers for all the common parameters such as ammonia and phosphate. The Liquiline System CA80 range provides online colorimetric analyses with the common user interface and hardware that everybody is already familiar with from the Liquiline transmitters. The measurement range covers all required parameters with true COD and total phosphate being recently added.
