Blue Spot Water

Features :

• Fully Automatic Operation: Controlled by a Programmable Logic Controller (PLC) for continuous, reliable operation.

• Automatic Backwash & Flush: Includes self-cleaning cycles (backwash and chemical enhanced flushing/CIP) triggered by time or pressure differential to maintain membrane efficiency.

• High Flow Rate: Capacity of 20,000 LPH (or 20 m3/hr).

• Robust Construction: Skid-mounted and non-corrosive materials (often Stainless Steel or FRP) suitable for industrial environments.

• Low Operating Pressure: Operates at significantly lower pressure than Reverse Osmosis (RO) systems.

• Modular Design: Allows for scalability and easier maintenance access.

   

What does it do:

The system clarifies and purifies water by physically sieving out contaminants at the micron and sub-micron level. It effectively removes:

• Turbidity and Suspended Solids: Provides a stable, very low-turbidity output.

• Microorganisms: Eliminates virtually all bacteria and viruses.

• Colloids and Macromolecules: Removes high molecular weight organic and inorganic polymeric substances.

Its primary application is to produce high-quality process water or serve as an essential pre-treatment step to protect more sensitive downstream equipment, most commonly a Reverse Osmosis (RO) system.

Good to know:

• Not a Desalinator: UF does not remove dissolved salts, ions (like sodium, chloride, calcium), or very low molecular weight organics. If salt rejection is required, an RO system must follow the UF.

• Required Pre-Treatment: Raw water often requires a Multi-Media Filter (MMF) and an Activated Carbon Filter (ACF) upstream of the UF system to remove larger sediments and chlorine, protecting the UF membranes from rapid fouling or chemical damage.

• High Recovery: UF systems generally have a very high water recovery rate, often exceeding 90-95% of the input water.

Maintenance:

• Routine Backwash: Automated counter-current flushing with purified water every 20-60 minutes to clear the membrane surface.

• Chemical Enhanced Flush (CEF): Periodic flushing with chemicals (e.g., acid/alkaline solutions) to remove accumulated organic and inorganic foulants.

• Clean-In-Place (CIP): Intensive chemical cleaning (weekly/monthly) to restore membrane performance.

• Membrane Replacement: UF membranes typically have a service life of 3 to 5 years, depending on water quality and maintenance.

What is in the box:

• Skid-mounted UF unit assembly.

• UF membrane modules installed in pressure vessels.

• High-pressure or booster pump(s) for the UF stage.

• Automatic multi-port/solenoid valves and process piping.

• Instrumentation (flow meters, pressure gauges, pressure sensors).

• PLC-based control panel.

• Associated pre-treatment filters (e.g., MMF, ACF) may be shipped as separate modules.

Dimensions : 

Dimensions are highly variable depending on the manufacturer and the inclusion of pre-treatment.

• Estimated Footprint (UF Skid Only): Approximately $2.5\text{m}\times 1.5\text{m}\times 2.0\text{m}$ (Length x Width x Height).

• Total System Footprint (with pre-treatment): Significantly larger, often requiring a dedicated room or containerized solution.
