x UK Focus - Water/Wastewater Report on How Operator Self-Monitoring Can Lower Costs


Wastewater represents a cost to business. Hach Lange (UK) has produced a report on how Operator Self Monitoring (OSM) can not only reduce discharge and treatment costs but also boost profit by increased product recovery and reduced energy consumption.


In recent years, the Environment Agency (EA) has shifted towards OSM where water companies and processing industries self monitor their discharge and report results to the EA. The frequency of monitoring is dictated by a combination of the risk posed by the discharge and assessment of the quality of the operator's monitoring regime.


Operators have a choice; they can either hope that the spot checks are accurate, or they can conduct their own monitoring to make sure that it is. Self-monitoring can deliver much more than an accurate charge for wastewater; it can create a better understanding of a process and thereby improve efficiency.

Determining the presence or absence of fluids is an important feature of many products. Whether we need industrial sensors to know the fluid levels in a large industrial tank, coffee machine or oil reservoir or to identifying leaks in pumps, the performance of the products has to be very reliable but be commercially priced. Traditionally the use of float switches has dominated this market as the low cost solution for fluid level detection. Alternative technologies such as optical sensors have historically been viewed as desirable but too expensive. SST Sensing Ltd (UK) have taken the challenge to bring very reliable and robust optical fluid sensors into the market at a cost which is now comparable to float switches.


Where float switches have moving parts and can therefore be susceptible to mechanical failure or become defective due to particulate in the fluids, SST optical level sensors have no moving parts, they are very small and will reliably detect the presence or absence of fluid over many millions of cycles.


Their new key offering is to be able to price these at a level which makes them a superior alternative to float switches at a comparable price. SST Sensing Ltd’s latest designs are very reliable and can be used in a very wide range of fluids. The current applications include tank level controls, engine coolants, oils and other fluid level detection, leak detection in pumps, telecoms boxes and mobile phone masts, ink level detection, white goods and vending, plus many more. They can be used virtually anywhere where the presence or absence of fluid is required to be known.

Multiparameter Handheld and Smartphone Application Transforms Collecting Water Quality Data


The industry’s first water monitoring Smartphone App transforms the way environmental professionals collect water quality data.


Waterra-In-Situ Inc. (UK) have announced the new smarTROLL Multiparameter (MP) Handheld and iSitu Smartphone Application for environmental monitoring applications. Ideal for water quality spot checks, the smarTROLL MP Handheld can be used for any surface-water monitoring application. No training time is required to use the probe or the intuitive smartphone application. Technicians can instantly read results for 14 water quality parameters by simply using a smartphone – no bulky handheld meter is required.


Environmental professionals can use the durable smarTROLL MP Handheld to quickly assess water quality. In-Situ Inc.’s unique iSitu App, designed to run on an iPhone, iPod touch, or iPad, makes it easy to email data instantly to co-workers and to log site-specific data to a smartphone. By using readily available smartphone technology, instead of proprietary meters, environmental professionals reduce their overall cost of ownership. The compact smarTROLL System includes a compact probe with field-tested smart sensors and a clip-on battery pack with Bluetooth Wireless Technology.


The smarTROLL MP Handheld can be used for spot checking, stormwater monitoring, vertical profiling, and low-flow groundwater sampling. The smarTROLL MP System measures dissolved oxygen (DO), conductivity, ORP, pH, salinity, total dissolved solids, water level, barometric pressure, temperature, and more. Use the smarTROLL MP Handheld Low Flow Sampling System with In-Situ's unique Low Flow App for quality control and management of all your low flow groundwater sampling programmes. The probe features EPA-approved Rugged Dissolved Oxygen (RDO) technology for instantaneous DO determinations.
