Case Studies
Municipal Wastewater Treatment · Hach — Stock Configuration Case
Application Context
the inlet, biological and outlet stages of a municipal plant is a typical Municipal Wastewater Treatment duty. The project started from Hach, focusing on water analysis with Hach reagents and instruments.
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 Hach specification must therefore cover choosing reagents by method standard (colorimetric or titration) and range.
Delivery Approach
Delivery was handled as the stock channel — configuring from stock and delivered quickly. Execution centred on choosing reagents by method standard (colorimetric or titration) and range, together with stable compliance with Grade 1A discharge limits and online data reporting.
Field Results
Operation shows the benefit clearly — method consistency that lets historical data be compared over time, with confidence in this measuring point improving markedly.
Food & Beverage · Hach — Stock Configuration Case
Customer Profile
The typical setting in Food & Beverage is dosing, pasteurising, filling and CIP stages. The measuring point is Hach; the focus is water analysis with Hach reagents and instruments.
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 reagents by method standard (colorimetric or titration) and range.
Implementation
The scope ran through the stock channel: configuring from stock and delivered quickly. Technically it hinges on choosing reagents by method standard (colorimetric or titration) and range, and on these requirements: food-safety and hygienic design per 3-A / EHEDG.
Customer Benefit
In practice this means method consistency that lets historical data be compared over time, which cut the workload on the site maintenance team.
Chemical & Pharmaceutical · Hach — Stock Configuration Case
Project Background
The project covers reactors, metering vessels and finished-product tanks. The work centres on Hach and the core task is water analysis with Hach reagents and instruments.
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 Hach cannot be specified generically — it calls for choosing reagents by method standard (colorimetric or titration) and range.
Solution
The Ainstru engineering team worked through the stock channel: configuring from stock and delivered quickly. The configuration involves choosing reagents by method standard (colorimetric or titration) and range, 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 method consistency that lets historical data be compared over time.
Power & Energy · Hach — Stock Configuration Case
Project Overview
The site is boiler feedwater, turbine condensate and FGD/DeNOx systems. The customer wanted Hach properly configured on the existing plant, with the aim of water analysis with Hach reagents and instruments.
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 Hach configuration has to involve choosing reagents by method standard (colorimetric or titration) and range.
Configuration
Supply and installation were organised through the stock channel: configuring from stock and delivered quickly. On site this meant choosing reagents by method standard (colorimetric or titration) and range, checked line by line against: compliance with power-industry codes and unit availability targets.
Performance
After commissioning the outcome is method consistency that lets historical data be compared over time, and the readings are now used for process tuning.
