Water Treatment Filters: MMF, PSF & Side Stream Solutions
Interglobe Engineering offers advanced Multi Media Filters (MMF), Pressure Sand Filters (PSF), and Side Stream Filters (SSF) designed for efficient removal of suspended solids, turbidity, and impurities from water. These filtration systems are widely used in Water Treatment Plants (WTP), Sewage Treatment Plants (STP), Effluent Treatment Plants (ETP), and cooling tower systems. Our filtration solutions are engineered to improve water quality, protect downstream equipment like RO membranes, and enhance overall system performance.
Side Stream Filter
Purpose:
Side Stream Filters are designed for continuous filtration of cooling tower recirculation water, helping maintain clean and efficient system operation.
Description:
A Side Stream Filter treats approximately 5–10% of circulating water, removing suspended solids, silt, and biological contaminants. This improves cooling efficiency and reduces scaling and fouling.
Design Features:
- Flow range: 5 to 100 m³/hr
- Filtration type: Pressure Sand / Multi Media Filter
- Automatic backwash system with timer-based control
- Construction: MSRL / FRP vessels
Benefits:
- Reduces blowdown losses
- Maintains cleaner heat exchange surfaces
- Improves cooling tower efficiency
- Extends equipment life
Multi Media Filter (MMF)
Principle:
The Multi Media Filter (MMF) works on depth filtration, using multiple layers of granular media such as anthracite, sand, and garnet to remove suspended particles effectively.
Design Highlights:
- Filtration velocity: 10–15 m³/m²/hr
- Efficiency: 90–95% removal of suspended solids (>25 micron)
- Equipped with automatic backwash system using treated water
Construction:
- FRP / MSRL pressure vessel
- Frontal piping with flow measurement system
Applications:
- RO pre-treatment systems
- Tertiary treatment in STP & ETP plants
- Cooling tower water filtration
Advantages:
- High filtration efficiency
- Better dirt holding capacity
- Reduced maintenance frequency
Pressure Sand Filter (PSF)
Function:
A Pressure Sand Filter (PSF) is used to remove suspended solids, turbidity, and impurities from raw water, making it suitable for further treatment.
Design Parameters:
- Filtration rate: 10–12 m³/m²/hr
- Operating pressure: 2.5–4.0 kg/cm²
- Filter media: Graded silica sand (0.5–1.2 mm)
- Backwash rate: 15–18 m³/m²/hr
Applications:
- Pre-treatment before water softeners
- Industrial process water filtration
- Tertiary treatment in water systems
Benefits:
- Simple and reliable operation
- Cost-effective filtration solution
- Effective turbidity removal
