Municipal Wastewater Treatment

Municipal Wastewater Treatment · PH — Application Case

Application Context

the inlet, biological and outlet stages of a municipal plant is a typical Municipal Wastewater Treatment duty. The project started from PH, focusing on continuous pH monitoring for neutralisation and compliance control.

Process Constraints

effluent parameters drift and probes foul with sludge and biofilm, and high solids and corrosive fractions, with large diurnal flow swings only amplify it. The PH specification must therefore cover choosing glass or ISFET sensors by temperature, fluoride content and pressure.

Delivery Approach

Delivery was handled as the analyser range — selecting as part of a complete water-analysis system. Execution centred on choosing glass or ISFET sensors by temperature, fluoride content and pressure, together with stable compliance with Grade 1A discharge limits and online data reporting.

Field Results

Operation shows the benefit clearly — tighter dosing control and lower reagent consumption, with confidence in this measuring point improving markedly.

Food & Beverage

Food & Beverage · PH — Application Case

Customer Profile

The typical setting in Food & Beverage is dosing, pasteurising, filling and CIP stages. The measuring point is PH; the focus is continuous pH monitoring for neutralisation and compliance control.

Key Difficulties

Conditions are syrups, dairy and beverages that scale easily, under strict hygienic requirements and, on top of that, frequent cleaning demands instruments that withstand hot CIP/SIP caustic cycles, which a standard configuration cannot handle for long. The design therefore starts with choosing glass or ISFET sensors by temperature, fluoride content and pressure.

Implementation

The scope ran through the analyser range: selecting as part of a complete water-analysis system. Technically it hinges on choosing glass or ISFET sensors by temperature, fluoride content and pressure, and on these requirements: food-safety and hygienic design per 3-A / EHEDG.

Customer Benefit

In practice this means tighter dosing control and lower reagent consumption, which cut the workload on the site maintenance team.

Chemical & Pharmaceutical

Chemical & Pharmaceutical · PH — Application Case

Project Background

The project covers reactors, metering vessels and finished-product tanks. The work centres on PH and the core task is continuous pH monitoring for neutralisation and compliance control.

Operating Challenges

The medium and duty are characterised by highly corrosive media with solvents and crystallisation, partly in explosive atmospheres, and corrosion plus Ex protection shortens instrument life and makes downtime costly. So PH cannot be specified generically — it calls for choosing glass or ISFET sensors by temperature, fluoride content and pressure.

Solution

The Ainstru engineering team worked through the analyser range: selecting as part of a complete water-analysis system. The configuration involves choosing glass or ISFET sensors by temperature, fluoride content and pressure, with these requirements in view: Ex certification and GMP traceability of records.

Results

Since start-up the system has run steadily; the practical result is tighter dosing control and lower reagent consumption.

Power & Energy

Power & Energy · PH — Application Case

Project Overview

The site is boiler feedwater, turbine condensate and FGD/DeNOx systems. The customer wanted PH properly configured on the existing plant, with the aim of continuous pH monitoring for neutralisation and compliance control.

Technical Challenges

What actually causes trouble is high temperature and pressure with both steam and saline water, and drift under high temperature and pressure, with very costly unplanned outages. All of this means the PH configuration has to involve choosing glass or ISFET sensors by temperature, fluoride content and pressure.

Configuration

Supply and installation were organised through the analyser range: selecting as part of a complete water-analysis system. On site this meant choosing glass or ISFET sensors by temperature, fluoride content and pressure, checked line by line against: compliance with power-industry codes and unit availability targets.

Performance

After commissioning the outcome is tighter dosing control and lower reagent consumption, and the readings are now used for process tuning.
