Blue Spot Water

Features :

• High Flow Capacity: Nominal capacity of 10,000 Liters Per Hour (LPH).

• Automatic Operation: Typically features a PLC (Programmable Logic Controller) or automatic valve heads for operation, including automated backwash and rinse cycles.

• Membrane Technology: Utilizes high-performance Ultrafiltration membranes, commonly Hollow Fiber (e.g., PVDF), with a very small pore size (e.g., 0.01 to 0.03 microns).

• Material of Construction: Often built on a robust skid-frame, with piping and components made from materials like Stainless Steel (SS-304) or FRP (Fiber Reinforced Plastic), depending on the model and required durability.

• Pre-Filtration Stage: Generally includes a pre-treatment section such as Sand/Multi-Grade Filter, Activated Carbon Filter, and Micron/Security Filter to protect the UF membranes.

• Monitoring Instruments: Includes a control panel, pressure gauges, and flow meters.

• High Removal Rate: Achieves high removal rates (e.g., $>99.99\%$) for bacteria and viruses.

What does it do:

The system uses hydrostatic pressure to push the source water through a semi-permeable Ultrafiltration membrane. The membrane acts as a physical barrier, effectively separating:

• Suspended Solids

• Colloidal Material

• Bacteria and Viruses

• Endotoxins and other pathogens

• Larger organic molecules It produces high-purity water with low silt density, making it suitable for drinking water production, wastewater recycling, or as a crucial pre-treatment step before Nanofiltration (NF) or Reverse Osmosis (RO) to prevent membrane fouling.

Good to know:

• Filtration Size: Ultrafiltration membranes typically have a pore size ranging from 0.01 to 0.1 microns.

• Low Operating Pressure: UF systems generally require lower operating pressure compared to RO, leading to lower energy consumption.

• No Chemical Regeneration (for the UF membrane): The membrane is physically cleaned through automatic backwash and rinse cycles, though chemical cleaning (e.g., with acids or bases) is periodically required.

• Does NOT Remove: Unlike Reverse Osmosis, UF does not typically remove dissolved salts, ions, or very low molecular weight organic solutes.

• Application: Ideal for industrial, commercial, and municipal water treatment.

Specifications:

• Capacity: 10,000 Liters Per Hour (LPH) or 10 m3/hr (varies based on raw water quality).

• Automatic Grade: Fully Automatic or Semi-Automatic

• Power Supply: Typically 3-Phase power (e.g., 380V/415V/460V, 50/60Hz).

• Filtration Capacity (UF Membrane): $\approx 0.01$ microns.

• Max Recovery Rate: Up to 98% (varies by design and water source).

• Operating Pressure: Typically low to moderate (e.g., minimum 1.5 kg/cm2 or higher for certain designs).

• Material: Steel / FRP / SS-304 (Skid/Piping).

• Recommended Pre-treatment Parameters: Max. Turbidity: $<300\text{ NTU}$ (for some robust models), TSS $<50\text{ mg/L}$, Chlorine must be removed (often via Activated Carbon) before the UF membrane.

Maintenance:

• Routine: Automatic and regular Backwash and Rinse cycles of the UF membranes and pre-filters (Sand/Carbon).

• Periodic: Chemical Enhanced Cleaning (CEB) of the UF membranes using cleaning chemicals (e.g., acid, caustic, or chlorine solutions) to remove scaling and organic fouling. Frequency depends on the raw water quality.

• Component Replacement: Scheduled replacement of micron filter cartridges, filter media in the pre-filters (Sand/Carbon), and eventual replacement of the UF membranes (typically after several years, depending on usage and cleaning effectiveness).

What is in the box:

(Note: Components are typically supplied as a pre-assembled skid or in modules for on-site assembly)

• Main Ultrafiltration Skid/Frame.

• UF Membrane Housing(s) and UF Modules/Membranes.

• Raw Water/Booster Pump(s).

• Pre-filtration Vessels (e.g., Multi-Media Filter, Activated Carbon Filter) with multi-port valves (manual or automatic).

• Security/Cartridge Filter Housing(s).

• Control Panel (PLC or electrical components).

• Interconnecting Piping, Valves, and Flow/Pressure Meters.

• Chemical Dosing Pumps (e.g., for backwash/cleaning chemicals, coagulant/flocculant, or chlorine)
