Water and wastewater treatment plants are designed to treat all municipal waste. Water treatment encompasses many processes from the collection, treatment, disposal of sewage and distribution of clean water for it to be reused in our home and business.

The Process

The process of water purification results is the by-product of harmful combustible and toxic gases which can create hazardous environments that must be continuously monitored to protect workers visiting the plant, neighbours of the plant and the environment.

a1-cbiss supply and service gas monitoring equipment to most of the UK’s water companies – United Utilities, Anglian Water, Thames Water, Welsh Water, Severn Trent, Southern Water and Yorkshire Water.

Pumping Stations

Wastewater from local communities arrives at the wastewater plant through underground pipework. Pumping stations are often enclosed areas and are classified as confined spaces. This can lead to a build-up of toxic Hydrogen Sulphide emanating from the stagnant wastewater. Highly sensitive survey monitors are used to carry out assessments on site for the purpose of data logging.

Primary Treatment

Some primary treatment facilities use Hydrogen Peroxide as a pre-treatment additive, so oxygen levels should be monitored closely. Also, if primary treatment is done in an indoor facility, Methane, Hydrogen Sulphide, and Oxygen levels must all be monitored closely to ensure safety for anyone entering the process facility.

Odour Control

Air scrubbers and carbon absorbers remove odours and volatile organic compounds (VOC’s) from treatment process off-gases.

Odour control is used in all wastewater processes and performance is constantly monitored and governed by local regulations.

Hydrogen Sulphide is typically the primary odour concern; however, Ammonia also requires monitoring.

Our Solution: Odour Loggers

Specifically designed to operate in the humid and toxic environment, Odalogs will continuously monitor levels of gas for reporting purposes.

Boundary Monitoring

Bad odours are often the complaint of neighbours to the wastewater plant. Sites should install gas sensors around the boundary to indicate how much gas is passing the fence line.

Mapping software provides a picture of the whole site and highlights problem areas. These gas detectors provide low-level ppb measurement whilst operating using solar power.

Case Study - How EfW Operators are Benefiting From a Biogenic CO2 Sampler

To obtain ROC’s, the operator must prove biogenic content is at 50% or greater. With our Ofgem approved sampler, operators can be confident of submitting accurate results to claim ROCs.

Case Study - CO2 Detection System Commissioning at Brewery

If leaks go undetected, CO2 is a major threat to health within the brewing industry. a1-cbiss comissioned a fixed gas detection system for CO2 and O2 ready to provide visual warnings once alarm levels are reached.
