Definition of Task: Metrologic inspection of flow measuring equipment according to German self-control ordination (EKVO). Inspection of flow measurement at relevant discharge point according to German regulations.
Measuring the oil content in water or soil is a specialty of Wilks Enterprise. InfraCal TOG/TPH Analyzers provide on-site ppm measurements to help ensure upstream or downstream wastewater complies with discharge permits to avoid potentially costly fines. There are over 3,000 InfraCal TOG/TPH Analyzers in operation today around the world measuring the oil and grease levels in produced water on drilling platforms, oil content in FRAC water, hydrocarbons in wastewater effluents from refineries, and TPH in soil at...
The Township of South Glengarry installs a new Greyline AVFM 5.0 Area-Velocity Flow Meter to measure continuous discharge from their municipal sewage lagoon. The sealed ultrasonic sensor is mounted in a horizontal 12` PVC pipe. The AVFM replaced a magnetic flowmeter that was unable to measure seasonal low flow rates.
In a pit water purification system it was necessary to detect the discharge volumes. The operator wanted a regular and automatic transmission of readings. On the selected measurement place no mains power connection was available. Due to the risk of vandalism, it was not planned to install a switching cabinet.
See the NIVUS solution for this measurement task here.
Effective water quality monitoring is the key to environmental protection of watercourses and for reliable process control and wastewater treatment. Discharge consents under EPR regulations dictate that water quality monitoring is undertaken to ensure that consented parameters are below the consented concentrations. Traditionally this has been done using water quality sampling methods but increasingly automatic water quality measurement sensors linked to real-time telemetry is seen as the most reliable and...
The process of electricity generation from fossil fuels such as coal, oil and natural gas is water-intensive. Between 40-50% of all water abstracted and used in developed countries is used in the generation of electricity. Thus, a reliable, abundant and predictable source of raw water supply to a power plant is a critical factor in site selection. Water supplies are required to provide various process waters for the following essential main purposes such as make-up water, cooling water for steam turbine condensers,...
A Greyline AVFM Area-Velocity Flow Meter monitors and data logs water discharged from the Bray Quarry to the South Raisin River. The Quarry is required to measure flow for environmental permit compliance.
For rivers and streams we offer a range of impeller and electromagnetic current flow meters to use as a point velocity measuring devices to aid monitoring during catchment management, discharges and pollution.
Water level can be monitored via pressure transducer and logger together with radio and GSM/GPRS telemetry options.
As most tropical countries face unpredictable rain falls, building sites have to be managed differently. In Singapore an effective Erosion Control Measure (ECM) was required at a building site, in order to treat the storm water before discharging it to the public drain.
Hiden plasma probes measure some of the key plasma parameters and provide detailed information relating to plasma reaction chemistry.

A number of treatment products are often added to prevent corrosion, scaling and fouling. Coating of sensors and other effects of these products must be taken into account when selecting analyzers. Discharge monitoring needs special attention because zero measurements must be reliable over time with little maintenance.
The Sorbisense method allows for efficient monitoring of the sewage system and can help reduce costs of operation and environmental impact.
The method is particularly well suited for tracking the source of periodic discharges, the identification of faulty pipe connections of the measuring of values in the recipient.
The method also allows for measurements in dynamic sources - such as emissions from roads, roofs, parking lots and overflow
Chemical Oxygen Demand (COD) is used as a measure of organic pollutants in water. In wastewater treatment, it indicates the efficacy of a treatment process and is expressed in milligrams per litre (mg/L) or parts per million (ppm). Removing certain fractions of COD in waste streams can be particularly challenging, especially to levels safe for discharge to the environment.
Intake protection systems have been extensively installed to protect water treatment works, from ingress of polluted water and waste-water plants from toxic chemical loads. A suitable system typically comprises a suit of instrumentation, measuring key chemical, physical and indicator parameters dependant upon the identified risks, associated with the individual site activity or discharges from neighbouring industry.
Automation can save money, optimise a process and give warning of potential breeches of discharge consent. However, instrument selection is fundamentally important if a control system is to function efficiently. The measurement device must accurately and quickly respond to process variations and it must be reliable in operation if the control system is to function as intended. Designed properly, energy and chemical use can be significantly reduced, saving money and ultimately improving effluent quality.
Problem: Industrial manufacturers face stringent regulations for discharging wastewater to the environment and municipal sewer systems. Biochemical Oxygen Demand (BOD) is a primary concern for many discharge limits, as wastewaters high in BOD can have adverse impacts on the aquatic environments by leading to oxygen depletion. In some cases, as a means to supplement BOD, it is also desirable to monitor chemical oxygen demand (COD) of industrial effluents. Both of these tests, are time and labour intensive reducing...
Drinking water is not the only area requiring flow monitoring. The disposal and cleaning of waste water also requires flow meters. Waste water used to be dumped directly into the soil or an open channel. As awareness has increased, most discharges are now treated to assure long term sustainability. Modern water treatment plants are highly complex systems that require the use of flow sensors to monitor flow velocity in open channels for waste water discharge. Likewise facilities for waste water collection and...
The history of air pollution regulation dates back as far as the 13th century when in 1273, Edward I (Longshanks) of England prohibited the burning of sea coal in London. The smoke produced by its combustion was considered detrimental to human health.
By the late 19th and early 20th centuries, regulations were being passed that sought to control air pollution predominantly for smoke and odour control. Traditionally, regulators were concerned with the visual impact of the discharge from a stack or chimney. Therefore...
In industrial manufacturing companies, before a new process comes on-line, it is important to measure the toxicity of the effluent stream. This is especially the case for companies who treat their own waste. From the toxicity value (EC50) obtained, it may be a cost-effective solution to simply discharge the effluent to the treatment works at a slow and defined rate to minimise damage to the activated sludge. Following a period of acclimatisation it is often possible to increase feed rates to the plant and this...
