Automating Water Treatment Plant Design With A Web-Based Flow Sheet Platform

Our client’s water and environmental engineering faced a major constraint: designing large-scale treatment plants is manual and requires many resources. Relying on huge design teams to manually map out complex unit operations creates significant project delays, inflates engineering costs, and limits operational scalability.

The Outcome

The Challenge

A leading Water and Environment Management company needed to increase their project delivery but found their traditional, manual flow sheet design process was not sustainable, risking lost commercial bids and lower profit margins.

Limited Engineering Capacity

The inability to quickly prototype treatment combinations such as moving effluent from a clarifier to a reverse osmosis unit capped the volume of projects they could manage and bid on at once.

Inaccurate Resource Use

Using large engineering teams for routine parameter calculations led to inconsistent plant designs and spent specialized human labor on repetitive, slow drafting tasks.

The Solution

Entrans delivered a web-based design application, combining an Angular JS frontend with a Python and Springboot backend to automate complex plant engineering.

Direct Flow Sheet Interface‍

We developed a frontend where engineers visually move unit operations from ultrafiltration and settlers to pumps and dosing systems mapping out water transformations immediately.

Parameter Automation

The application uses hard-coded company parameters to automatically calculate flow logic and unit sizing, removing the need for manual calculations at every stage of the treatment process.

LLM Historical Retrieval

We added Ion Genie, an LLM that fetches past project data matching the specific unit patterns, allowing for data-driven design based on historical models.

Backend Architecture

Powered by Python and Springboot, the system seamlessly processes complex design permutations for both Industrial and Sewage Effluent Treatment Plants (ETP/STP) without latency.

Complete Lifecycle Mapping

The tool dynamically accounts for advanced post-treatment stages, including thermal evaporation for RO reject water, ensuring total water recovery optimization.

‍

The Outcome

The enterprise is now able to achieve faster, more reliable water treatment plant designs. Automated parameter calculations and historical data retrieval have dramatically improved engineering scalability.

175% faster flow sheet design and prototyping

99% parameter accuracy across automated unit operations

50% increase in commercial project bidding capacity

We have been working with Entrans for the last two years and they have played a key role in building our solution. Their expertise and professionalism were evident throughout the development cycle, and we were very pleased with the final product. They have shown enormous skill and vast domain knowledge and their IT expertise is reliable and trustworthy. We would recommend Entrans for anyone looking for quality IT services, delivered in a professional manner
