PTPL Solution

A brief on the process involved

The treatment process starts off with filtration, for which the Pressure Sand Filter and the Activated Carbon Filter are made use of.

In the Pressure Sand Filter, sand is used for removing the suspended particles while anthracite removes the odor as well as the color to make the water fit for various applications. Pebbles and gravels are provided to support to both the media.

Operating Data:

Mode of Plant Operation	Manual
Raw Water Feed Flow Rate	15.0 Cu.m / Hr
Operating Pressure	3.5 Kg / Sq. Cm
Filter Media	 Sand, Silex, Gravels & Pebbles

The Activated Carbon Filter uses carbon of a specific grade as media and is mainly used for color and odor removal.

Water Softener System:

Once the water is basically treated of solid suspensions and contaminants, a softener is used to remove the hardness from raw water.

Reverse Osmosis System:
RO is used to produce high purity water that meets the most demanding specifications. It is capable of up to 99.5 % salt rejection, yet, on account of its very fine membranes, it is very much prone to fouling with various contaminants such as colloids, heavy metals, oil and grease etc. As RO membranes are highly sensitive, micro filtration is gaining popularity as an RO pre treatment solution world wide.

An RO plant is designed on 8 Cu.m / hr / Stream product flow rate with an average recovery of 60%. The feed water at a Reverse Osmosis Plant shall be at 15.0 Cu.m / Hr / Stream.

The above system is designed on the raw water analysis which is furnished with, below:
