Frequently Asked Questions
What can I find in the WECOME Resources center?
The resource center gathers everything you need to plan and run an RO membrane element line: free calculators for materials and output, product selection guides for machines and raw materials, material data sheets, quality and testing references, production tools and templates, and technical FAQs. It covers all common element sizes from 1812 to 8040.
Are the calculators and resources free to use?
Yes. All calculators, guides, data sheets and checklists are free to use. They are built from real RO membrane element production experience so you can size your materials, plan your line and check your quality process before you invest.
Which RO membrane element sizes do the resources cover?
The resources cover the standard spiral-wound element sizes — 1812, 2521, 3013, 4040 and 8040 — from small samples and household elements through to high-volume industrial production.
I’m setting up a new production line. Where should I start?
Start with the Production Setup Guide and Line Layout Guide to plan your line, use the calculators to size materials and output, then choose equipment with the rolling machine and automation guides. When you are ready, contact our engineering team for a tailored line recommendation and quote.
Does WECOME supply the materials and equipment as well?
Yes. WECOME is a one-stop supplier of RO membrane element raw materials and production equipment. The resources here are written by the same engineering team, so you can move from planning to a fully equipped line with one partner.
