Iron Removal & Pesticides Removal Plant

Working principle:

In sand filters water enters in the filter and percolates through the filter bed. Suspended matter present in the water comes in contact with the media particles and is trapped on the top of the bed.Followed by this, clean water comes out through the filtration nozzles and through the filter outlet. Periodically cleaning of this filter is done by back washing. Water is introduced in the reverse direction of the service flow that is from the outlet nozzle upwards causing suspension of the turbid material in the filter bed & finally flushing out through the back wash valve. The Filter is then down rinsed & clear water is taken in the system.

Filter media:

Filter Media are used depending on the raw water quality and the treated water quality required. Our range of seven bedded filtration systems custom made to achieve the turbidity level of less than 1NTU & Suspended solids less than 10 ppm. The Filtration beds comprises of the coarsest beds starting from Pebbles of 30 - 40 mm size to the finest layer of fine sand 0.8 mm to 1.6 mm size.

Advantages:

• Better filter quality at higher flow rate
• Negligible Pressure drop
