Compact UF Water Filtration System – Economical Solution for Small to Medium Projects

Description

DAGYEE UF Ultrafiltration System

Product Overview

Not every water treatment project needs a massive industrial system. Many applications fall into a different category—smaller in scale, tighter in budget, but still demanding reliable, high-quality water. Think of a village water supply serving a few hundred people. A hotel or resort that needs consistently good water for guests. A school that wants to ensure its drinking water is safe. A farm that requires clean water for livestock or irrigation. A small factory that can't afford production disruptions from poor water quality.

These aren't niche applications. Across the world, thousands of such projects are planned and built every year. Yet the equipment options available often lean toward either over-engineered industrial systems that break the budget, or under-engineered residential units that simply can't handle the demand.

The DAGYEE Compact UF Water Filtration System bridges that gap. It's designed specifically for projects in the 0.5 to 10 m³/h range—right in that sweet spot between small residential systems and large industrial plants. It packs professional-grade membrane filtration into a compact, affordable package that delivers commercial-grade performance without the commercial-grade price tag.

Why Ultrafiltration for Small to Medium Projects?

There's a reason ultrafiltration has become so popular in recent years, even for smaller-scale applications. The technology simply makes sense.

No Chemicals Needed
During normal operation, a UF system doesn't require any chemical dosing. No coagulants, no flocculants, no pH adjustment. This is a significant advantage for smaller installations where chemical handling, storage, and safety can be a hassle. You just pump water through the membranes, and clean water comes out.

Consistent Quality, Regardless of Feed Water
Conventional filters (sand filters, media filters, cartridge filters) produce water that varies with the quality of the incoming water. During dry seasons, they work fine. During rain events, when turbidity spikes, the output quality drops. A UF system doesn't care about seasonal fluctuations. The membrane pores are physical barriers. If the contaminant is larger than 0.01 microns, it stays behind. Period. The permeate quality is the same in April as it is in November.

Small Footprint
For smaller projects, space is often limited. You might not have an entire building for a water treatment plant. UF systems are compact. A system producing 5 m³/h fits on a skid about the size of a small car. It can go into a corner of an existing building, a shipping container, or a small dedicated room.

Low Maintenance
Modern UF systems are automated. They backwash themselves. Some models can even do simple chemical cleanings automatically. This is a big deal for smaller operations that don't have a dedicated water treatment specialist on staff. With a UF system, routine operation is straightforward. Check the pressures in the morning. Top up the chemicals if needed. The system handles the rest.

Long-Term Reliability
UF membranes have a service life of 3 to 5 years with proper operation. That's much longer than sand filters that require regular media replacement, or cartridge filters that need changing every few months. The total cost of ownership usually comes out ahead with UF.

How This System Works

The Compact UF System follows the same tried-and-true operating principles as its larger industrial counterparts.

Here's the sequence:

Filtration Mode
Feed water enters the system and passes through a pre-filter rated at 100 microns. This removes large debris that could damage the UF membranes. The water then flows into the UF membrane modules. These modules contain thousands of hollow fiber membranes. Under pressure (typically 1.0 to 3.0 bar), water passes through the membrane pores while contaminants are retained. Clean permeate exits the system, ready for use. The rejected contaminants are concentrated in a small reject stream that goes to drain or is recycled.

Backwash Mode
Over time, contaminants accumulate on the membrane surface, causing the pressure required to push water through the membrane to increase. The system monitors this through a parameter called Transmembrane Pressure (TMP). When TMP reaches a set point, the system automatically triggers a backwash cycle. Clean water or permeate is pumped in the reverse direction through the membranes, flushing accumulated foulants off the surface and out to drain. This takes about 60 to 120 seconds.

Chemical Cleaning (When Needed)
If backwashing isn't enough to restore flux, chemical cleaning may be required. The system includes simple chemical feed capability for Sodium Hypochlorite (NaClO) and/or citric acid, depending on the configuration. These chemicals remove organic and inorganic foulants that backwashing alone can't handle. For most installations, this might be needed weekly to monthly, depending on feed water quality.

The entire sequence—filtration, backwash, and optional chemical cleaning—is controlled automatically. In the simplest version, a timer-based control handles the backwash schedule. In more advanced versions, a PLC with a small HMI touch screen provides full programmability and monitoring.

System Components

The UF Ultrafiltration System consists of the following core components:

What This System Removes

The Compact UF System is a physical barrier. It removes anything larger than its pore size. Here's what that means in practical terms:

What the System Does NOT Remove:

• Dissolved salts (TDS)

• Dissolved ions (sodium, calcium, chloride, etc.)

• Low molecular weight organics

• Color that is truly dissolved (not particle-bound)

For applications requiring dissolved solids removal, UF is typically followed by reverse osmosis or ion exchange. In fact, one of the most common uses of UF is as pretreatment for an RO system—it removes the particulates that would otherwise foul the RO membranes.

Where This System Is Used

This compact UF system shows up in a wide range of applications. Here's where we most often see it installed:

Installation & Setup

One of the advantages of the Compact UF System is its simplicity. Here's what you need to know:

What You Get
The system arrives fully assembled on a steel skid. All piping, the UF membrane modules, the feed pump, the control panel, and the instrumentation are already connected. The pre-filter is installed. The backwash system is plumbed. It's essentially plug-and-play.

Connection Requirements

• Water Supply: Pipe connection to your feed water source (well, tank, municipal supply, or surface water)

• Permeate Discharge: Pipe connection to your product water tank or distribution system

• Reject / Drain Discharge: Pipe connection to drain or recycle line (small flow, typically 5-10% of feed)

• Power: Single-phase electrical connection at the specified voltage

• Space: Level floor area sufficient for the skid, plus 600 mm access around all sides for maintenance

Commissioning
A trained technician can commission the system in one day. The process includes flushing the membrane modules, checking all instrumentation, programming the control parameters, and verifying performance. Operator training takes about 2-3 hours.

Operator Requirements
No specialized technical background is needed. The system is designed so that a facilities manager, maintenance person, or even a trained operator can handle the daily tasks. The checklist is simple: check pressures, monitor flow rates, top up chemicals if applicable, and call for service if something looks unusual.
