Dear Sir,

Sub. : Sand filter and Softener

This is in reference to the discussion we had regarding fitting a water treatment plant to remove hardness present in water. We are pleased to submit herewith the scheme for setting up a Softener based on the requirement . Hardness assumed is 650 ppm.

What are the effects of Hardwater?
Hard water can be detected easily, even as one performs personal hygiene such as hair washing, or through the appearance of fixtures and appliances or changes in heating costs.
• Clogged pipes and/or appliances could be a sign of hard water. Hard water mineral deposits can form in coffee makers and can build up in pipes or plumbing equipment. A consumer may notice a reduced water flow, as well as an increase in the number of calls to a repair person.
• Consumers may notice a film on their bathtubs or shower tiles, or even on themselves. The film that is left often results in additional scouring and scrubbing of the affected fixtures, and can cause hair to be dull and limp, and dry the skin.
• A consumers water heating costs could increase as a result of hard water. When hard water is heated, the minerals can precipitate and form scale. Besides buildup, mineral deposits can form an insulating barrier between the heating element and the water to be heated.
• The calcium and magnesium in hard water act on many soaps and detergents to reduce their sudsing and cleaning capabilities. The soapy residue they form can be abrasive and reduce the life of clothing.

DESIGN BASIS & TREATMENT SCHEME

REQUIREMENT

The requirements of softened water from Softener.

TREATED WATER QUALITY AT VARIOUS STAGES OF WATER
TREATMENT PLANT

1. Ex Sand filter : < 1 NTU
2. Ex Water Softening Plant
Total Hardness : < 50 ppm as CaCO3


PROPOSAL

Based on the above, we have envisaged the following water treatment scheme, to cater to your requirement for your flats:-

Proposed Scheme

Raw water pump  sand filterSOFTENER  Overhead Storage water tank

Technical specifications:

Multigrade Sand filter LGMGSF 1848: The Lifeguard Sand filter is a depth filter that makes use of coarse and fine media mixed together in a fixed proportion. This arrangement produces a filter bed with adequate pore dimensions for retaining both large and small-suspended particles. This filter consists of the vertical cylindrical FRP pressure vessel . One set of internal water distribution and collection system. One initial charge of filter sand ,and under bed material . One set of frontal pipe work and valves. Two pressure gauges to monitor head loss across the filter. . The valves are manually operated.

Vessel size MEDIA Multiport valve size Internal distribution Maxm flow rate
Frp vessel 1848 dm engg Coarse silex, fine silex and fine sand
200 kgs, media depth 915 mm Multiport valve side mounted 40 nb Top and bottom distributors 4000 ltrs/hr

Water Softener LG SF2058: Considering hardness level of 600 ppm with a resin quantity of 240 liters and the output between regeneration is 20 m3. The Lifeguard Softener is a manually operated ion exchange unit designed specially for domestic/apartment use. It is simple to operate, inexpensive to maintain and is widely used in the domestic sector. The softener comprises a FRP pressure vessel containing a bed of cation exchange resin, a regenerating system and control valves. A strongly acidic cation exchange resin in sodium form is sued to exchange sodium ions for the hardness forming calcium and magnesium ions

Vessel size Resin qty Multiport valve size Internal distribution Maxm flow rate
