Are you searching for high-quality Pressure Sand Filters in Nandambakkam Chennai? We design and manufacture advanced filtration systems that remove suspended solids, turbidity, and impurities from water efficiently. As a result, industries, commercial buildings, and residential complexes achieve consistent water clarity and improved operational performance.
We provide a wide range of standardized and custom-built Pressure Sand Filters (PSF). Moreover, our systems operate effectively as pre-treatment units in RO plants (ROP) and as post-treatment solutions in wastewater treatment plants (STP & ETP). Therefore, they play a critical role in complete and dependable water purification systems across Chennai.
First, raw water enters the pressure vessel under controlled pressure. Then, it flows through multiple layers of precisely graded filtration media, which include:
Graded Quartz Sand
Fine Sand
Super Fine White Sand
Pebbles of progressively larger sizes
Because of this multi-layer filtration structure, the filter bed traps dirt, suspended particles, and turbidity effectively. During the filtration cycle, the media captures impurities and prevents them from passing downstream. Consequently, the treated water becomes clearer and suitable for further purification processes.
However, as filtration continues, the filter media gradually accumulates retained particles. As a result, the pressure drop across the vessel increases steadily. Once the pressure reaches a predetermined limit, the system temporarily shuts down for cleaning.
To maintain maximum efficiency, we implement a structured backwash process. When the pressure drop increases, the system reverses the water flow. Therefore, trapped impurities are flushed out from the filter bed quickly and effectively.
After backwashing, we rinse the filter using raw or filtered water. Then, once the required water quality is achieved, the system resumes normal operation. Depending on the application and water quality standards, we perform backwashing with either raw water or filtered water.
Because of this controlled cleaning cycle, the Pressure Sand Filter ensures long service life, reduced maintenance costs, and consistent filtration performance.
Our Pressure Sand Filter systems include:
Mild Steel (MS), Stainless Steel (SS), or FRP Pressure Vessels
Frontal piping work for smooth and secure operation
Manual or Automatic Multiport Valves
Butterfly Valves or Conventional Valves for easy control
Furthermore, we offer capacities ranging from 1,000 Liters per Hour (LPH) to 10,00,000 Liters per Day (LPD). Therefore, we can meet small, medium, and large-scale industrial and commercial water treatment requirements in Nandambakkam and throughout Chennai.
