Pressure Sand Filter

Q: Where is a Pressure Sand Filter used?

PSF is commonly used in: RO pretreatment systems, Cooling towers, Boiler feed water systems, ETP/STP plants, Industrial process water, Drinking water treatment plants.

Q: What impurities does a PSF remove?

A Pressure Sand Filter removes: Turbidity, Suspended solids (TSS), Mud and silt, Sand particles, Rust and scale particles, Colloidal impurities (partially).

Q: What is the difference between PSF and Activated Carbon Filter?

Pressure Sand Filter removes suspended particles, uses sand media, improves clarity. Activated Carbon Filter removes chlorine, odor, color, and organics, uses activated carbon media, improves taste and smell.

Frequently Asked Questions

What is a Pressure Sand Filter?

A Pressure Sand Filter is a water treatment unit used to remove suspended solids, turbidity, dirt, sand particles, and other impurities from water by passing it through layers of filter media.

Where is a Pressure Sand Filter used?

PSF is commonly used in:

RO pretreatment systems
Cooling towers
Boiler feed water systems
ETP/STP plants
Industrial process water
Drinking water treatment plants

What impurities does a PSF remove?

A Pressure Sand Filter removes:

Turbidity
Suspended solids (TSS)
Mud and silt
Sand particles
Rust and scale particles
Colloidal impurities (partially)

What is the difference between PSF and Activated Carbon Filter?

Pressure Sand Filter	Activated Carbon Filter
Removes suspended particles	Removes chlorine, odor, color, and organics
Uses sand media	Uses activated carbon media
Improves clarity	Improves taste and smell

What is the operating pressure of a Pressure Sand Filter?

Typically 2.5 to 7.0 kg/cm², depending on the system design and application.

How often should backwashing be done?

Backwashing is generally done:

When pressure drop increases by 0.5-1.0 kg/cm²
Once every 1-3 days for continuous operation
As per water quality and load

What is backwashing?

Backwashing is the reverse flow of water through the filter to clean the sand media and remove trapped impurities.

How long does the filter media last?

High-quality sand media usually lasts 3 to 5 years, depending on water quality, operating conditions, and proper backwashing.

Can PSF remove dissolved salts or TDS?

No. A Pressure Sand Filter does not reduce TDS or dissolved salts. For TDS reduction, an RO Plant or DM Plant is required.

What is the filtration flow rate?

The typical filtration rate is 10-20 m³/hr per m² of filter area, depending on design.

What materials are available for PSF vessels?

Pressure Sand Filters are available in:

FRP (Fiber Reinforced Plastic)
MSRL / MSEP (Mild Steel Rubber Lined / Epoxy Painted)
SS304
SS316

What is the inlet water turbidity limit?

For best performance, inlet turbidity should generally be below 50 NTU. Higher turbidity may require clarification before filtration.

How do I know the filter needs cleaning?

Signs include:

Increased pressure drop
Reduced flow rate
Poor water clarity
Frequent downstream filter choking

Can PSF be installed before an RO plant?

Yes. A Pressure Sand Filter is one of the most common pretreatment units before an RO system and helps protect membranes from fouling.

What maintenance is required?

Regular maintenance includes:

Periodic backwashing
Checking pressure gauges
Inspecting valves and piping
Replacing media when required

What capacity of PSF do I need?

The required capacity depends on:

Flow rate (m³/hr)
Water quality
Turbidity level
Operating hours per day
