BIOX-1010 ON-LINE BOD ANALYSER
BIOX-1010 is an on-line analyser for continuous BOD measurement in industrial and municipal wastewater treatment plants. BOD data are generated with a lag time of only 3 to 15 minutes, with a
standard measurement range of 20 to 1500 mg/liter BOD and available ranges covering 5 to 100,000 mg/liter. The real-time BOD data correlate well with five-day BOD5 laboratory results.
Wastewater is continuously pumped through a sample bypass. The peristaltic pump built into BIOX continuously feeds a small stream of wastewater from the sample bypass to the bioreactor. Before it reaches the bioreactor, this wastewater stream is diluted with oxygen-saturated dilution water supplied by a gear pump.
Inside the bioreactor, microorganisms grow inside small plastic cylinders where they are protected against mechanical abrasion caused by turbulent mixing. The respiration rate of the microbial population is automatically maintained at a constant level by a feedback loop that varies the dilution ratio. Increasing contamination of the wastewater increases the respiration rate, which in turn increases the dilution rate. Similarly, if the contamination level of the wastewater decreases, so does the dilution rate. The wastewater concentration in the reaction chamber is thus kept at a constant, low level, and the mixing ratio of wastewater and dilution water is used to calculate the BOD parameter.

COMPUTERS (CONTROLLERS) - AQUASWITCH
What it Does:
The AQUASWITCH™ is a special purpose dedicated computer which automatically "changes out" an exhausted DI bank for a fresh, stand-by bank. LEDs continually give the condition of both
banks. An alarm output is activated as each bank is depleted.
How it Works:
When the monitor/controller senses poor quality water merely because the DI system has been shut down temporarily, the AQUASWITCH purges the "on-stream" bank until water quality recovers. If the DI bed is exhausted, however, water quality will not improve sufficiently after purging. The AQUASWITCH will then automatically take the exhausted bed out of service and switch over to the stand-by bank. The fresh bank is purged until the desired quality level is reached; it then goes into service.
The purge cycle is controlled by a timer which is easily adjustable for periods from 1-10 minutes. This feature allows the system to be tailored to the requirements of each application, and ensures banks are not switched or shut down prematurely. A "manual change over" button can be depressed to switch banks at any time.
The AQUASWITCH features advanced circuitry, including three solid state (not mechanical) relays to reliably operate the solenoid valves. Three or four solenoid valves suitable for ultrapure water (not supplied) are needed to make a complete AQUASWITCH system.
Two models to choose from:
The standard AQUASWITCH I does not monitor water quality itself, but may be used with any reliable resistivity or conductivity monitor/ controller such as the Myron L 750 Series II. The AQUASWITCH II is an integrated unit with a built in 750 Series II Resistivity or Conductivity Monitor/controller. They are available in several ranges.

TRANSMITTER KAJAANIMCA CONSISTENCY
The kajaaniMCA Consistency Transmitter is the ultimate device for measuring and controlling total consistency in pulp and paper processes. It uses patented microwave-based technology, which allows
it to measure total consistency independent of the fiber length, freeness, wood species or blend present in the process stream. Solids such as fibers and fillers conduct microwaves faster than water so that shorter microwave transmission times will correlate to higher consistencies. This relationship is linear, making it is easy to calibrate the device regardless of what is being measured. Broken, recycled fiber, or other difficult pulp, is handled without a problem.
Additionally, the measurement is not affected by flow rate, brightness or color, which further contributes to better control of the finish, fewer process upsets and less off-grade product. The kajaaniMCA is simple to install: no high-voltage motor, motor starters, special cables or seal water installation is necessary. Therefore, it does not require regular maintenance, and it keeps commissioning and running costs to a minimum.

COLITAG™ SYSTEM
Colitag™ System
The Colitag System is a breakthrough in Coliform testing. The test enables the simultaneous detection, identification and confirmation of total coliforms and E.coli in 24 hours or
less.
The examination of water for microbial pollution is a major health undertaking. Drinking water supplies, swimming pools and spas are all regularly monitored for the indicator organism Escherichia coli (E.coli). Currently there are two accepted methods in use – Multiple Tube fermentation (MTF) and Membrane Filtration (MF). Both are designed to enumerate the secondary indicator group, total coliforms.
There are several drawbacks to these current methods of bacteriological testing – in particular the time taken to generate confirmed positive results, usually two to five days. Moreover, the subjective nature of interpreting results, the lengthy and labour intensive procedure involved and the susceptibility to interference by non-coliform heterotrophic bacteria, all detract from these methods.
The Coliform Testing System
A simple, reliable technique is required which eliminates these drawbacks and enables the rapid, confirmed enumeration of both total coliforms and more importantly, E. coli.
Colitag is a pre-dispensed dry blended reagent formulation containing salts, nitrogen and carbon sources and specific indicator/nutrients for total coliform and E. coli. Positive samples are detected by a visible colour change.
Performing the Coliform test is simple. The reagent is supplied in pre-measured dosage tubes for dispensing into sterile containers. Simply fill a sterile tube to the level, mix and then incubate at 35 ° C. The formation of a yellow colour in 24 hours or less indicates the presence of total coliforms. Positive tubes are then checked for the presence of E.Coli by looking for fluorescence under UV light.
The Colitag™ Principle
In theory, coliforms are organisms that are closely related to E.Coli. Since E.Coli is present in the digestive tract, and not in the general environment, this organism is used as an indicator of Faecal contamination in water or food samples. Colitag™ incorporates a three stage process for definitive coliform testing.
ONPG test indicates the presence of beta-galactosidase (unique characteristic of of coliform in general; coliforms utilise lactose to produce gas or acid.
MUG test to identify the presence of beta-glucuronidase (unique characteristic of E.Coli). But one third of E.Coli are MUG-negative, meaning they do not have this enzyme in their metabolic pathway.
Indole test – a second test specific for E.Coli, in case the MUG fails to identify the presence of E.Coli
You cannot rely on the MUG test alone to identify the E.Coli in a sample. The solution is to incorporate the Indole test in the media, but since lactose would interfere with the Indole test, ONPG is substituted.
A single inoculation can be performed with less than 2 minutes hands-on time. Conclusive results are available in 24 hours or less without the need for confirmatory tests or sub-cultures.
This breakthrough has been made possible by recent developments in defined substrate technology. This enables the simultaneous detection of total coliforms and E.coli by a simple colour reaction. Simply add water, incubate and read. Total coliforms are identified by a yellow colour in the incubated sample, E.coli is confirmed by fluorescence observed under UV light.
