Flocculation Equipment

Posted by craig.f@dtkwater.com

Jar testers are designed for a range of applications – such as testing the efficiency of flocculation or precipitation agents. Lovibond® offer 3 different models tailored for different requirements. The ET 730 is designed for field use with 4 compact stirring places arranged around a central lamp. Where both the ET 740 with 4 stirring places and the ET 750 with 6 stirring places are built for laboratory use and incorporate an illuminated back panel.

All the jar testers feature state-of-the-art technology ensuring maximum operating convenience and minimum maintenance. The jar testers all have continuously variable stirring speed, digital display of stirring rpm, timer function, illumination back panel (or lamp for ET 730) and height adjustment for the stirring blades during operation.

Chemical Oxygen Demand

Posted by craig.f@dtkwater.com

It is vital that industrial effluents comply with regulatory consents imposed by local water autorities/environment agents. Discharge maximums are often set for COD and TOC as these general measurements of discharge water quality. Other consent levels can be set for the process of specific items such as chromium, phosphate and nitrogen Heavy fines are possible for continued breaches of consent values. The Lovibond ® COD system is simple to operate, requires no training and enables industry to rapidly assess effluent quality and remain fully compliant.

The Lovibond® Chemical Oxygen Demand system is made up of 3 components; the MD100 COD photometer, the RD125 thermoreactor and COD Vario tube tests.

COD VARIO Tube Tests

The Lovibond® COD VARIO tube tests use a sealed tube system based upon the standard dichromate method and can be consindered as an estimate of the theoretical oxygen demand, i.e the amount of oxygen consumed in total chemical oxidation of the organic constituents present in the water.

BD600-400x400

BD600 – Biological Oxygen Demand Manometer

    • Manometric analysis of BOD for accurate, direct display of measurements
    • On-Screen display of graph.
    • Direct sample selection
    • Measuring range 0 to 4000 mg/l
    • Selectable measuring period: 1 to 28 days
    • Inductive stiring system
    • Mercury free, environmentally friendly
    • Remove control functionality
    • BD600: complete unit with 6 heads and control unit
    • BD606: 2 x complete BD600 each with 6 heads and control unit

Description

BOD – Biological Oxygen Demand – is an expression for the quantity of oxygen required for biological degradation of organic mater in a waste water sample. BOD measurement is therefore used as a basis for the detection of biologically degradable organic matter in water. The difference between BOD and Chemical Oxygen Demand (COD) is that COD additionally registers biologically non-degradable organic mater

BOD measurement is therefore an important measurement of the effects of domestic and industrial waste water on sewage plants and outflow points.

The unit is easy to use and set up using crolloing menus on the LCD display. Results can be monitored throughout the incubation period to ensure accurate analysis. With a selectable automatic start function, variations in sample temperature prior to testing can be eliminated, as the unit will begin the analysis period only when temperature is constant. Such variations would normally cause errors during manometric measurement.

An inductive stirring unit is also supplied to provide constant mixing of the sample over the analysis period.

The Lovibond® BD600 series is a manometric, respirometeric BOD measurement system. Manometric respirometers relate oxygen update to the change in pressure caused by oxygen consumption while maintaining a constant volume. Thanks to the modern integral pressure sensors, it is no longer necessary to use mercury for pressure measurements.

The unit is a 6 sample system that allows precise measurements of BOD from 1 to 28 days. Data is stored in the individual sensor heads, so it is possible to remove and re-position the bottles without losing vital data. By using different volumes of sample, the BD600 is capable of measuring from 0 to 4000 mg/l without the need to dilute the sample. Overflow measuring flasks are supplied with the unit, and a full range of flasks are available. BOD CM tablets, which can be used to verify the validity of results. can also be supplied.
