Aluminium Monitoring

Posted by Angus Fosten on November 24, 2016

Aluminium Analysis for Monitoring of Residual Coagulant  In many treatment processes Aluminium salts such as Aluminium Sulphate and Polyaluminium Chloride (PAC) are added to act as a coagulant to aid in the removal of solids and contamniants such as Phosphate. Traditional dosing control regimes rely on timers and predetermined diurnal patterns. Errors ...

Turbidity for Coagulant Control

Posted by Angus Fosten on May 2, 2014

Turbidity as a dosing trim parameter Control of coagulant dosing chemicals in wastewater treatment is an important issue, it links directly to both the site operating cost and the effectiveness of the treatment process. Partech have successfully worked with a number of the UK's water companies to apply our TurbiTech Self Cleaning ...

Sludge Blanket Monitoring

Posted by Liminal Design on

Continuous monitoring of the sludge/water interface or sludge blanket is central to the efficient operation of clarifiers, thickeners and settlement tanks. Reliable measurement enables a control system to maintain the optimum depth of sludge in the tank. A sludge interface that is too high can result in pollution incidents caused ...

Sludge Blanket Detection

Posted by Liminal Design on

A common requirement in the operation of sewage, wastewater and water treatment works is to find the location of the interface between the high solids region of a settlement tank, picket fence thickener or clarifier and the relatively lower solids region above.Detecting the presence of the Sludge Blanket at a ...

Wastewater Temperature Monitoring

Posted by Liminal Design on

Temperature measurement in wastewater applications provides an important back up to measurements such as pH, Dissolved Oxygen, Suspended Solids and Turbidity.  In Final Effluent many discharge consents are waived when the temperature reaches a low level of around 4ºC and by using a verifiable temperature measurement device such as the ...

Dissolved Oxygen

Posted by Liminal Design on

Being able to act on accurate measurement of Dissolved Oxygen in activated sludge plants will enable you to maintain levels of bacterial activity, avoid breaches in discharge consents and operate as cost effectively as possible. Too little dissolved oxygen can lead to bacterial inactivity and ineffective treatment, whilst too much, ...

Turbidity (Drinking Water)

Posted by Liminal Design on

Monitoring Turbidity in the Drinking Water Process Turbidity is an excellent early indicator of process problems, high intake levels will cause filter problems and possible blockages and an increase in turbidity in the final water can indicate filter failure and is an indicator of possible cryptosporidum in the water.Dosing and energy savings ...

Turbidity (Discharge Monitoring)

Posted by Liminal Design on

Monitoring Turbidity or Suspended Solids in Effluent Discharges. Monitoring Final Effluent Suspended Solids or Turbidity is a key parameter for assessing the quality of the effluent in respect of meeting discharge consent and permitting levels. It is also an excellent indicator of the basic performance of the treatment works. An increase ...

Sludge Density

Posted by Liminal Design on

Monitoring In Line Sludge Density or Suspended Solids In-line measurement of sludge density and/or suspended solids has a major impact on the effectiveness of monitoring the solids content in sludge, from the intake stage through to treatment and disposal. Using information collected from online instruments, the operator can automatically control the ...
