Water & Wastewater Pipe Flow Simulation Software

Trusted by

Engineering Simulation Tools

Design and troubleshoot multiple levels of your engineering projects with Datacor’s suite of simulation software.

CHEMCAD

Modern chemical process simulation software designed with the engineer's workflow in mind to help efficiently identify innovative solutions.

Fathom

Calculate steady-state hydraulic pressure drop and pipe flow distribution in liquid and low-velocity gas piping and ducting systems.

Arrow

Determine the pressure drop and flow distribution, analyze sonic choking, and model real gases in steady-state gas and steam piping systems.

Impulse

Analyze pumping systems for harmful pressure surge transients caused by water hammer.

Fathom

Eliminate energy waste and pump oversizing

Identify head losses, optimize pump curves, and right-size pipes to cut power costs by up to 20 %. Run sensitivity cases in minutes to reveal the optimal blend of efficiency and redundancy.

Optimize Your Systems

Impulse

Stop water hammer before it starts

Simulate transients, valve slam, and pump trips to specify surge tanks and dampers that shield mains and valves from damaging pressure spikes. Protect piping assets and reduce unplanned downtime tied to transient-induced fatigue.

Analyze Surge Transients

Arrow

Optimize blower sizing and air header design

Calculate pressure drops and compressor operating points across complex aeration grids to ensure uniform dissolved-oxygen delivery at minimal kW / SCFM. Sensitivity analysis highlights throttling versus speed-control trade-offs, cutting aeration energy by up to 30 %.

Fathom Settling Slurry (SSL) module

Keep slurries suspended and equipment intact

Calculate critical velocity, pressure drop, and pump derating to prevent solids settling and abrasive wear in lime, grit, or biosolids lines. Side-by-side scenario comparisons verify long-term reliability and OPEX savings.

Prevent Blockages

Fathom & Arrow GSC Module

Hit flow-balance targets automatically

This automated solver frees engineers to focus on design insight instead of trial-and-error iterations. Iterates pump/compressor speeds, valve settings, and line sizes until flows and pressures meet permit limits—no spreadsheets required. Or you can iteratively adjust damper positions and fan speeds until airflow targets are met.

Find Solutions Faster

Fathom & Arrow XTS Module

Evaluate slow transients with confidence

Model 24-hour demand curves and wet-weather events in Fathom so lift stations and clarifiers stay within capacity even on peak days. Confidently document regulatory-ready contingency plans for peak-flow wet-weather events. You can also simulate 24-hour digester gas generation in Arrow to size relief valves that protect digesters from over-pressure.

Analyze Slow Transients

CHEMCAD

Validate chemical dosing

Model pH adjustments and blending requirements so operators hit effluent specs without overdosing chemicals. The result is fewer costly overdoses and tighter compliance with discharge permits.

CHEMCAD Dynamics

Stress-test plant upsets in real time

Dynamic simulation reveals how temperature swings or feed shocks impact chemical stages, enabling control response. Engineers can prototype PLC logic virtually, shortening commissioning time and avoiding late-stage rework.
