BIOLOGICAL WASTEWATER TREATMENT SYSTEM The BioAmp biological wastewater treatment system, from NCH Australia, combines microbiology and engineering. FreeFlow tablets and the BioAmp system work together as a successful remediation program. The FreeFlow bacteria are fastidious and ready to eat up organic waste as soon as they enter the wastewater treatment plant. The tablets contain five different types of bacteria that break down the organic waste and convert it into water and CO2. This in turn generates more bacteria. The BioAmp solution will eliminate the need for excessive aeration and foul odours in the wastewater treatment plant and aid in meeting effluent parameters (BOD, COD, TSS and FOG). It works the same for drain maintenance, and eliminates plugged drain lines causing back-ups, unsanitary overflow and plumbing. The system is suitable for industries such as hospitality, food and beverage, and commercial/retail/entertainment facilities. Foul odours throughout the drain network are also eliminated, along with any high reading of FOG that exceeds permitted levels. NCH Australia www.nchasia.com/en-au

SMART METERS FOR WATER, HEATING AND COOLING The MULTICAL range of smart energy meters,

LOW-POWER, VARIABLERELUCTANCE PRESSURE TRANSDUCER Validyne introduces the DP15, a variablereluctance pressure transducer capable of low to high pressure measurement with low power consumption. It features a replaceable pressure sensing diaphragm which allows pressure measurement from 0.08 to 3200 psi in 23 full-scale ranges. This makes it viable for a wide range of applications in one compact unit. The product consists of a flat diaphragm (magnetically permeable) supported between two coils which produces a magnetic field when an AC excitation is applied. The opposition to the lines of flux (called the reluctance) is determined by the air gap present between the two coils and the diaphragm. The coils are wired electrically as an inductive half-bridge. Built with flexibility in mind, it provides wet/wet differential measurements and accepts liquids and gases on both sides of the diaphragm. In addition, a small internal pressure cavity volume ensures fast response to pressure

by Kamstrup, is used to meter and submeter water and thermal energy use in large residential and commercial buildings. More and more property managers and building owners are introducing individual metering in their buildings. By installing individual consumption meters for each department or tenant, they receive precise measurements and a constant flow of data. The key to these results is in the meter, with advances in technology bringing about static meters that are said to be precise and provide long-term stability. The use of meters eases the burden of administration and manpower, allocates cost fairly and offers transparency of water and thermal energy use. This transparency can be used to actively steer and reduce consumption, simply by changing behaviours. Aquip Systems Pty Ltd www.aquip.com.au

variations. It is built to last and able to withstand extreme shock and vibration due to its heavy-duty stainless steel construction. Specially built units are also available for use in sea water, saline solutions, brine and other corrosive media. Bestech Australia Pty Ltd www.bestech.com.au
