SRB & Sea Water UV Treatment Packages

atg UV Technology have recently designed and manufactured a state of the art, containerised UV disinfection package for the treatment and removal of SRB's (Sulphate Reducing Bacteria) from sea water.

The system incorporates two parallel trains of three SX-635-16 UV Systems in series.  To avoid problems associated with maintenance and corrosion, atg UV Technology manufactured all UV systems, manifolds and associated piping from Super Duplex 25% Cr Steel.

The UV treatment package included six SX-635-16 UV chambers, six power control cabinets, two three in one integrated SPECTRA control panels, 18 inch manifolds, 12 x 16 inch butterfly valves and a state-of-the-art UV Transmittance Monitor.  

All the equipment was installed within a custom made, 20ft offshore rated shipping container.  The container design included interior and emergency lighting, air conditioning, heating, insulation, drip trays, custom designed crew access doors and was designed for a single point lift.  Additionally a specially designed recessed power socket was provided for ‘Plug and Play' operation on site. 

Each UV treatment stream is designed to treat over 1000 m3/hr with a minimum dose of 40 mJ/cm2 at a transmittance of 90%.  The normal operation capacity for the system is 3000 m3/hr using 3 x UV systems, however up to 6 UV systems can be brought online at once to accommodate either a drop in water quality or an increase in flow.      

UV disinfection, supplemented by periodic shock dosing using chemical biocides is perfectly suited to down-hole injection applications, and has proved to be both a cost effective and highly efficient method of removing harmful microorganisms such as SRB's (Sulphate Reducing Bacteria) from water sources.

A correctly sized atg UV system such as the featured atg UV disinfection package dramatically reduces the amount and frequency of chemical dosing and vastly reduces the associated handling / transportation costs.  Estimated savings for a SRB treatment application such as down-hole injection switching to UV treatment are substantial in chemical biocide cost savings alone.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
