Water Treatment Plant

Sand filtration is frequently used and very robust method to remove suspended solids from water. The filtration medium consists of a multiple layer of sand with a variety in size and specific gravity. Sand filters can be supplied in different sizes and materials both hand operated or fully automatically. raw water pump is used for generating necessary operating pressure in the pressure sand filter. Raw water is passed through chemtronics multigrade sand filter at a pressure of 3. 5 kg / cm2 to reduce the suspended solids present in the raw water.

Applications for sand filtration :

• preparation of cooling water
• treatment of waste water
• production of drinking water
• filtration in swimming pools
• pre filtration for membrane systems
• filtration of gray or surface water
• swimming pool water

Multi grade sand filter :

The multigrade 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. multigrade sand filter is highly recommended for the removal of suspended solids & un-dissolved impurities like dust particles & heavy metals etc. Doing so it reduces turbidity. Pressure sand filter is an ideal solution for the systems with high sediment, silt, sand, and turbidity. Our sand filters are well established in media filtration technology. The sand filters are specially designed to take care of the range of suspended impurities. Chemtronics filtration series multigrade sand filter include vessel complete with piping & valves sand media and gravel support bed.

Applications: -

The multigrade sand filter is an ideal choice for all applications where a conventional sand filter is used.

• it is extensively used in side stream filtration of cooling water.
• drinking water.
• it is ideal for filtration of clarified water.
• water used in chemical processes.
• filtration process in industries.
• used for pre – treatment for membrane systems.
• swimming pool water filtration.
• filtration in tertiary waste water treatment.
• pharmaceutical production processes.

Pressure sand water filter fr series

Fiber glass reinforced plastic (fgrp) composite vessels are 1/3 the weight of carbon steel, strengths are directly comparable to steel, no maintenance & high aesthetic appearance.

Salient features:-

• the non corrosive, cost effective solution for commercial /industrial water treatment and storage
• frp vessels are used for residential, large commercial and industrial applications.
• vessel is made up of natural fiberglass shell never fades or changes color, colored shells recommended for uv protection.

• physical properties: operating pressure – min 0 bar and max. 10 bar.
• factory test pressure – 11 bar.
• operating temp – min. 1°c and max. 50 °c
• the light weight of composites can lead to cost saving like lower installation costs easier handling.
• top & bottom opening vessel.
• low pressure drop across the vessel.

Five stages of reverse osmosis procedure:

Stage i: sediment filter

the 10 micron polypropylene sediment pre-filter to remove suspended materials as sediment, dirt, dust, rust and other suspended impurities down to 10 micron from the water.

Stage ii: activated carbon granule filter:

Removes free chlorine and other organic substances, unpleasant colour, tastes & odours from the water and improve quality.

Stage iii: activated carbon block filter:
Removes any additional chlorine and organic substances from the water without release of carbon fines. The carbon block prepare water to enter the ro membrane

Stage iv: ro membrane (0. 0001 micron):
High rejection (95-99%) thin film composite r. O. Membrane to reject wide spectrum of impurities including total dissolved solids (tds), bacteria and viruses down to 0. 0001 micron.
Stage v: polishing resin carbon filter:
Bacteriostatic resin carbon filter dissolved gases bad taste and odour to ensure fresh and natural tasting crystal clean water

Features of reverse osmosis water purification system :

• thin film composite 75 gpd membrane.

• five stage purification.

• hygienic pressurised 15 liters storage tank.

• fully automatic.

• membrane flushing system.

• long reach chrome faucet.

• all parts are nsf listed.

• the pressure pump is protected and prolonged for a long – term usage.

Different categories of reverse osmosis :

• reverse osmosis light commercial
• reverse osmosis heavy commercial
• reverse osmosis light industrial
• reverse osmosis heavy industrial

Ozone generator

We manufacture & supply ozone generators worldwide in all application of air, water & wastewater treatment. Our ozone generator ranges from 2gm/hr to 20kg/hr. We also provide ozone generator for large application in multiple options.

The key factor for the success of ozone technology is not only having the equipment but its integration & implementation. And we have master this art over a period of time in all applications of hotels, hospitals, office buildings, it parks, industries, factories, food processing, malls, exhibitions centre, water treatment applications, sewage treatment plants, laundry, hvac/ahu, cooling tower, etc.

Swimming pool water disinfection is one of the key treatment steps for all types of public, private in ground & above ground pool. Efficient pool water disinfection is essential. Swimming pool water is contaminated by swimmers & environment pollutants. For many years, chlorine or bromine based chemicals have been the standard disinfectants used in swimming pool water treatment. However, studies have proven that the use of these chemicals can have health consequences due to the formation of reaction byproducts, mainly chlorinated organic compounds and chloramines. Chloramines are responsible for eye, ear and throat irritation as well as the presence of strong “chlorine” odor. Certain viruses, amoebae and cysts are also not inactivated at the chemical levels normally used for pool water treatment.

Ozone generator in swimming pool water treatment

numerous other private, public, commercial, water park, hotel, spa and motel swimming pools have switched to ozone technologies as people become more concerned about chlorine and chlorinated byproducts.

Advantages of ozone in swimming pool water treatment: 

• no eye irritation.
• no skin blackening.
• no harmful disinfectant byproducts (dbps.
• if ozonated water swollen not dangerous gas.
• more effectively destroys bacteria, viruses, fungi, algae & spores.
• 1. 33 times more powerful than chlorine.
• 3,100 times faster than chlorine.
• ozone has a micro-flocculation property.
• o3 destroys organism such as phenols, pesticides, herbicides & pcbs.
• oxidizes inorganic such as cyanides, sulphides & nitrites.
• oxidizes soluble ions & manganese.
• removes colors.
• removes odors.
• reduces turbidity.
• red operates bet. Ph 6 to 9uces tds
• waste (backwash) water does not require any treatment.
• environmentally friendly.

Disadvantages of swimming pool chlorination: 

• eye reddening & conjunctivitis.
• skin rashes & skin blackening.
• hair fall increases.
• disinfectant byproducts are very dangerous.
• produces trihalomethane (thm), which is carcinogenic.
• if swollen, chlorinated water is very dangerous.
• environmentally hazardous.

Critical aspect of ozone technology:

ozone is produced at site the key to this technology is its integration with the swimming pool water treatment plant & how ozone is dosed in proportion to the contaminants developed by swimmers & environment pollutant in swimming pool water.
