Common Challenges in Pool Engineering Projects

“Too many options, afraid of choosing the wrong system?”
“Equipment scattered, interfaces incompatible?”
“Complex commissioning slowing down project deadlines?”

These are the pain points most swimming pool contractors and engineers face: mixing different sand filters, pumps, and dosing systems on site, causing delays, compatibility issues, and endless back-and-forth with designers, suppliers, and clients. Traditional sand filters may look simple, but in large-scale or high-end pool projects, they often mean longer construction time, bigger space requirements, and higher maintenance costs.

One System, One Solution

The SmartClean Precoat Membrane Filtration System solves these problems with a fully integrated design, combining filtration, pumping, dosing, and intelligent control in a single compact unit. With this system, pool engineers no longer act as “equipment patchers” but become efficient “project managers.”

High Integration

• Pump, dosing tank, filter, and PLC controller built into one unit

• Occupies only 60% of the space of traditional sand filter systems

• Quick installation with “plug-and-play” pipe connections

Modular & Factory Pre-Assembly

• Standardized interface design, fully compatible with pool plumbing systems

• Reduces rework, saves construction time, and minimizes risk

• Shortens project delivery by up to 50% compared to sand filter projects

Intelligent Control

• One-click switching between precoat, filtration, and regeneration modes

• PLC automation for real-time water quality management

• No manual backwashing, unlike traditional sand filters

Value Across the Entire Project Chain

For Contractors

• Factory pre-tested and pre-adjusted → simple site connection

• Eliminates brand compatibility issues

• 50% faster installation compared to sand filter systems

For Design Institutes

• Standardized parameters reduce drawing revisions

• Space-saving design frees up valuable building area

For Operators

• Easy to operate, even without technical staff

• Stable water quality at <1 micron filtration precision

• Lower long-term maintenance cost compared to sand filters

Precoat Filtration vs. Sand Filter – A Quick Comparison

Frequently Asked Questions (FAQ)

Q1: Is a precoat membrane filtration system better than a sand filter for hotels and resorts?
Yes. While sand filters are cost-effective for small pools, precoat membrane systems deliver superior water clarity, faster installation, and automation—ideal for commercial and high-end pools.

Q2: Can I replace my existing sand filter with a precoat membrane filtration system?
Absolutely. The SmartClean system supports standard plumbing interfaces, making replacement or upgrade easy.

Q3: What makes this system different from traditional cartridge filters or sand filters?
Unlike cartridge filters that need frequent replacement or sand filters that require backwashing, the precoat membrane filter regenerates automatically, ensuring long-term stability with minimal maintenance.

Conclusion

The SmartClean Precoat Membrane Filtration System is not just a filter—it’s a fully integrated commercial pool filtration solution. It addresses the pain points of project complexity, scattered equipment, and long commissioning cycles, while offering higher efficiency and better water quality than traditional sand filters.

For contractors, designers, and operators, this is the next-generation choice to transform swimming pool projects into faster, smarter, and more sustainable solutions.
