Which wastewater analysing equipment is right for me?


Which wastewater analysing equipment is right for me?

Our guide to wastewater analytics.

The majority of businesses producing wastewater are required to carry out wastewater sampling to comply with their consent to discharge permit requirements. In most cases, an automatic effluent sampler is the most suitable option for accurately and reliably meeting sampling requirements. However, for some businesses additional analytical equipment can be helpful.


In this guide we’ll explain:


  • The main types of wastewater analysing equipment
  • How to choose the right equipment for your business
Wastewater samplers

Wastewater samplers are designed to automatically collect samples of wastewater and trade effluent via a hose at regular pre-programmed intervals. A thermoplastic unit keeps the samples at the optimum temperature. This is important as effluent contains Biological Oxygen Demand (BOD), which must be kept cold in order to be effectively measured. Automatic samplers are connected to a site’s wider flow measurement system and can function either independently or as part of an existing PLC/SCADA system.


There are two types of wastewater sampler – vacuum and in-line (guillotine). The version you need will depend on whether you have an open channel or closed pipe application.

Photometers & spectrophotometers

Businesses with larger sites or that require more detailed information on their wastewater status may benefit from additional analytical equipment.


Hand-held photometers and spectrophotometers offer a convenient way of conducting instant wastewater sampling analysis. They offer a range of testing options and pre-programmed tests, giving an immediate picture of wastewater analyte levels and understand how well you are meeting parameters within your consent to discharge. Results are instant which means you can check vital information on compliance and potential trade effluent costs without waiting for lab results.


This can be beneficial because factors such as products changes, new on-site processes and seasonal temperature variations can all have an impact on the quality and analyte levels within trade effluent. Having a portable device on-site is a quick and simple way to check analyte levels without the need for specialist laboratory equipment.

In-line monitors

In-line monitors are a good option for businesses that need to track specific analytes such as pH and turbidity in their wastewater, and provide a more affordable option than a photometer or spectrophotometer.


Depending on the nature of the business,  you may be required to test the following physical properties by MCERTS:


  • Temperature
  • pH
  • Salinity
  • Turbidity
  • Colour/odour


At SIRIS, we supply the Partech 7300w² Monitor, which is a great option for monitoring a range of values, comfortably accommodating up to eight sensors, with additional sensors a possibility depending on site capacity.


The 7300w² Monitor can be paired with sensors monitoring pH, temperature and turbidity, so it’s possible to pick and choose as required.

Partech partner

Our status as a Partech sales and service partner allows us to offer a range of analytical measurement devices, enhancing our service offering and giving our customers additional wastewater monitoring options. We can supply, install and maintain a range of Partech products and offer ongoing support to our customers.

Wastewater analysis data monitoring

In addition to on-site sampling and analytical equipment, many of our customers also opt to add on a Cloud-based data monitoring to their wastewater analysis package. Having the ability to track your site’s effluent discharge provides peace of mind and confidence that you are staying within your limits – as well as allowing you to see if you are paying too much.


Our data monitoring system uses a data visualisation suite paired with a specialist remote telemetry unit (RTU) to provide businesses with 24/7 access to their data, from anywhere with an internet connection.

How can you make sure you choose the right wastewater analysing equipment?

Wastewater analysis is a highly complex and confusing area, and it can be difficult to navigate the various options available. It’s essential you consult experts to ensure the system you choose is fit for purpose and cost-effective. Choosing the wrong products can be a costly mistake and there are a number of factors which can push the price up further, including poor installation practice and a lack of expertise from your supplier.

Ultimately, a correctly installed system supported by a team of experts is the only way to be sure you are getting a cost-effective and reliable system.

In addition to our range of MCERTS-approved wastewater samplers and analytical measurement tools, at SIRIS we offer comprehensive support and guidance to help you choose the best option for your site.
