HACH SG
The SG or ES series online water quality monitoring remote quality control instrument (the ES series is a customized product) uses a human-machine interface plus an IO board as the control core. By means of volumetric pure water in the sample cell and metering of the stock solution by the spiking pump, it achieves precise preparation for standard solution verification and spike recovery, providing the required water sample for online instruments. Before each operation, the water quality monitoring quality control instrument cleans and drains the sample cell to ensure the accuracy of standard solution verification and spike recovery.

Industry Applications:

The SG series online water quality monitoring remote quality control instrument is a product designed to work with online water quality monitoring instruments, and can be widely used in rivers, inland waterways, sewage discharge outlets, and other environments.

Municipal Wastewater Treatment

Municipal Wastewater Treatment · HACH-ONLINE — Application Case

Project Background

The project covers the inlet, biological and outlet stages of a municipal plant. The work centres on HACH-ONLINE and the core task is continuous outfall monitoring with Hach online instruments.

Operating Challenges

The medium and duty are characterised by high solids and corrosive fractions, with large diurnal flow swings, and effluent parameters drift and probes foul with sludge and biofilm. So HACH-ONLINE cannot be specified generically — it calls for configured by monitoring range, reagent replacement interval and conditioning.

Solution

The Ainstru engineering team worked through the online water-analysis line: integrating around each online monitoring point. The configuration involves configured by monitoring range, reagent replacement interval and conditioning, with these requirements in view: stable compliance with Grade 1A discharge limits and online data reporting.

Results

Since start-up the system has run steadily; the practical result is steady reagent and consumable supply, making upkeep predictable.

Food & Beverage

Food & Beverage · HACH-ONLINE — Application Case

Project Overview

The site is dosing, pasteurising, filling and CIP stages. The customer wanted HACH-ONLINE properly configured on the existing plant, with the aim of continuous outfall monitoring with Hach online instruments.

Technical Challenges

What actually causes trouble is syrups, dairy and beverages that scale easily, under strict hygienic requirements, and frequent cleaning demands instruments that withstand hot CIP/SIP caustic cycles. All of this means the HACH-ONLINE configuration has to involve configured by monitoring range, reagent replacement interval and conditioning.

Configuration

Supply and installation were organised through the online water-analysis line: integrating around each online monitoring point. On site this meant configured by monitoring range, reagent replacement interval and conditioning, checked line by line against: food-safety and hygienic design per 3-A / EHEDG.

Performance

After commissioning the outcome is steady reagent and consumable supply, making upkeep predictable, and the readings are now used for process tuning.

Chemical & Pharmaceutical

Chemical & Pharmaceutical · HACH-ONLINE — Application Case

Site Conditions

This is a Chemical & Pharmaceutical customer whose plant is at reactors, metering vessels and finished-product tanks. The main task was continuous outfall monitoring with Hach online instruments.

The Problem

The difficulty lies in highly corrosive media with solvents and crystallisation, partly in explosive atmospheres; at the same time corrosion plus Ex protection shortens instrument life and makes downtime costly. Specification therefore means configured by monitoring range, reagent replacement interval and conditioning.

What We Did

We took a online water-analysis line approach — integrating around each online monitoring point. Delivery was built around configured by monitoring range, reagent replacement interval and conditioning, with point-by-point checks on: Ex certification and GMP traceability of records.

Operating Outcome

In service the system performs as intended — steady reagent and consumable supply, making upkeep predictable, with routine maintenance falling noticeably.

Power & Energy

Power & Energy · HACH-ONLINE — Application Case

Application Context

boiler feedwater, turbine condensate and FGD/DeNOx systems is a typical Power & Energy duty. The project started from HACH-ONLINE, focusing on continuous outfall monitoring with Hach online instruments.

Process Constraints

drift under high temperature and pressure, with very costly unplanned outages, and high temperature and pressure with both steam and saline water only amplify it. The HACH-ONLINE specification must therefore cover configured by monitoring range, reagent replacement interval and conditioning.

Delivery Approach

Delivery was handled as the online water-analysis line — integrating around each online monitoring point. Execution centred on configured by monitoring range, reagent replacement interval and conditioning, together with compliance with power-industry codes and unit availability targets.

Field Results

Operation shows the benefit clearly — steady reagent and consumable supply, making upkeep predictable, with confidence in this measuring point improving markedly.
