Household UF Water Purifier System – Point-of-Use Compact Filtration for Residential & Commercial Drinking Water

Description

Household UF Water Purifier System – Point-of-Use Compact Filtration for Residential & Commercial Drinking Water

Product Overview

Millions of households around the world rely on municipal water supplies that are supposed to be safe. But the reality is more complicated. Aging infrastructure, treatment failures, and contamination events mean that tap water isn't always as safe as it should be. Boiling is inconvenient. Bottled water is expensive and creates plastic waste. And many point-of-use filters on the market don't actually remove the contaminants that matter most—specifically bacteria and viruses.

The DAGYEE Household UF Water Purifier System provides a better solution. Using advanced PVDF hollow fiber membrane technology, it removes bacteria, viruses, protozoa, and suspended solids from drinking water—without chemicals, without electricity (gravity-fed models), and without the ongoing expense of bottled water.

This system is designed for residential homes, apartments, offices, restaurants, and any application where clean, safe drinking water is required. It fits under a kitchen sink or on a countertop. It runs on water pressure or gravity. And it produces consistently high-quality water, day after day.

For families, this means peace of mind. For businesses, it means satisfied customers and reduced costs. For communities, it means reliable access to safe drinking water.

Why UF for Household Water?

Removes What Matters Most
Activated carbon filters remove chlorine taste and odor. Sediment filters remove sand and dirt. Neither of them reliably removes bacteria and viruses. UF does. The 0.01-0.02 micron pores are smaller than most bacteria and all viruses. It's a physical barrier—if it's bigger than the pore, it stays out.

No Chemicals
Unlike reverse osmosis systems that require pre-filters, post-filters, and sometimes remineralization, UF requires no chemicals. Just water pressure or gravity pushing water through the membrane.

No Electricity (Gravity Models)
The gravity-fed version operates without any electricity. It's ideal for remote areas, emergency preparedness, or locations with unreliable power. Fill the upper tank with water, and gravity pulls it through the membrane. Clean water collects in the lower tank.

Long-Life Membrane
The PVDF membrane has a service life of 3 to 5 years with proper maintenance. Compare that to carbon cartridges that need replacement every 3-6 months or RO membranes that require regular replacement and wastewater generation.

Preserves Beneficial Minerals
UF removes contaminants but leaves dissolved minerals in the water. This matters for taste and health—calcium, magnesium, and other minerals are retained. The water tastes natural and isn't "flat" like RO water.

Low Wastewater
UF systems produce very little wastewater (5-10% of feed). Compare that to RO systems that waste 3-4 liters for every liter of purified water produced. UF is water-efficient.

Compact and Simple
The system is small enough to fit under a sink or on a countertop. No complex installation is required. It connects to the existing water line or uses gravity feed.

How This System Works

Option A: Point-of-Use (Under-Sink) with Water Pressure

Step 1: Feed Water Connection
The system connects to the cold water line under the kitchen sink. A shut-off valve allows isolation for maintenance.

Step 2: Pre-Filtration
A sediment pre-filter (5-10 microns) removes sand, rust, and large particles before water enters the UF membrane. This protects the membrane from physical damage.

Step 3: Ultrafiltration
Water passes through the PVDF hollow fiber UF membrane. The 0.01-0.02 micron pores remove bacteria, viruses, protozoa, and colloids. Clean water passes through the membrane; contaminants are flushed away in a small reject stream.

Step 4: Carbon Polish (Optional)
An optional activated carbon post-filter improves taste and odor by removing chlorine and other volatile compounds. This is standard on some models and optional on others.

Step 5: Dispensing
Clean, purified water is available from a dedicated faucet installed on the sink or countertop.

Step 6: Automatic Flush
The system includes a manual or automatic flush valve to clean the membrane surface periodically. This simple maintenance step extends membrane life.

Option B: Gravity-Fed (No Electricity)

Step 1: Fill Upper Tank
Pour raw water into the upper tank. The water passes through a sediment pre-filter as it enters the tank.

Step 2: Gravity Filtration
Water flows by gravity through the UF membrane. No pump is needed. The membrane removes bacteria, viruses, and suspended solids.

Step 3: Collection
Clean water collects in the lower tank. A dispensing tap allows easy access to the purified water.

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.

Technical Specifications

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.
