Zeomedia Filtration Calculator

v7.0
Important Notice — Preliminary Design Data

The results generated by this calculator are preliminary design estimates for initial technical and economic evaluation purposes. They do not constitute a final engineering design or a formal quotation.

Filtration velocity parameters, equipment sizing, and financial analysis are based on typical ranges for Zeomedia 12×20 and 14×40 according to the official technical guide. Real project conditions may require specific adjustments.

A Zeomedia technical advisor will review your case and contact you to validate the design and provide a formal proposal.

Filtration Systems Calculator
Preliminary design with Zeomedia · 8 integrated calculation modules
How to use this calculator
8 sequential modules — complete each one in order
📋 Module 1 — Project & Quality

Define the treatment objective and water type. Enter turbidity or TSS. The calculator automatically recommends the appropriate Zeomedia filter media and baseline design velocities.

📐 Module 2 — Filter Geometry

Select whether the system is pressurized or gravity-fed. Choose a filter from the commercial catalog or enter custom dimensions. Define number of units and bed height.

🔄 Module 3 — Backwash

Configure the filtration cycle and backwash velocities. Define active phases (water, air, air+water, rinse). Calculates water consumption and system water balance.

⚙️ Module 4 — Pumps & Blowers

Size the backwash pump (by head or differential pressure) and the air blower if applicable. The flow rate is automatically inherited from the backwash module.

💰 Module 5 — Operating Costs

Enter water and energy rates in your currency of choice. Get the backwash OPEX per cycle, daily, and annual, with automatic conversion between USD, MXN, EUR, and SAR.

📈 Module 6 — Financial Analysis

Enter the project CAPEX. The calculator generates the cash flow table, cost NPV, and present cost per treated m³.

📬 Module 7 — Contact

Before the final summary, enter your contact information. The complete design summary is automatically sent to your email for review by a Zeomedia advisor.

📊 Module 8 — Executive Summary

Consolidated table with all key parameters from each module, active design alerts, and a side-by-side comparison vs Multimedia and Silica Sand with NPV savings.

Pre-filled from module 2 (equipment + zeolite + 10% contingencies). Adjust if you have a real quotation.
Default: 10% of CAPEX/year (maintenance, operators, spare parts). Adjust per your estimate.
Scales OPEX year over year: OPEX × (1+i)^year
Factor: 1 / (1 + r)^year → Cost NPV
