The policy of Shubham is to achieve and maintain a high standard of quality in all aspects of our operation and to continually satisfy the expectations of our customers in reverence of all the services offered.

We aim to ensure that the needs of our customers related to the water treatment are clearly understood and met through close liaison at all stages of the work. This is driven through a highly professional conduct with technological and commercial integrity. We implement pilot run for such water management to examine the implementation of the project and measure its success to make sure that desired performance is received when actually implemented in a holistic way across the plant of our customers. This comprises of sand and anthracite as filtering media and polishing media respectively. Internally it is fitted with inlet distributor and a bottom collecting system.

Externally, it is fitted with frontal pipe work and isolation valves. Sand is used for removing the suspended particles and anthracite removes the odor and colour etc to make the water fit for various application. Pebbles and gravels are provided to support to both the media. This filter is to be backwashed after accumulation of suspended solids over the cycle, however, before carrying out the backwash, air scouring (optional) is also to be done for loosening of dirt and suspended solids. Limit for the backwash in these filers is governed by differential pressure across the filter.

Type of filters in vertical/horizontal configurations are: Pressure Sand Filter Dual media filter Multi-Grade Filter
