L. M. Systems

Water naturally contains dissolved as well as un-dissolved impurities and precipitate sludge that can be removed by using effective filtration techniques. We offer clients various water filtration system based solutions that are capable of effectively removing different kind of impurities. The range offered by us include:

Features:

• Remove impurities depending on their flow rate
  
• Made from mild steal/FRP closed vessel
  
• Are operated under pressure
  
• Highly durable and functional
  
• Needs low maintenance and install
  
• Available at economic prices
  

Methodology:

• The water is passed through the filter from top to bottom, where unwanted impurities are left behind at the filter bed
  
• Back flushing very easily cleans the filter bed, thus reverse flow of water flushes away the impurities deposited at filter bed
  

Different types of filters offered by us:

Filter Type	Used For
Sand Filter	Removal of suspended impurities up to minimum level
Multi Graded Filter	High velocity flow rates of reduced area of filtration, in depth filtration
Activated Carbon Filter	Removal of free chlorine, phenol, taste & odor as well as reduction of COD/BOD.
Gravity Filter	Housing & Hotels and Municipal water supply
Swimming Pool Filter Plant	Operated at high flow velocity for recirculation loops

The presence of ions, calcium and magnesium results in hardness in water. These salts gets deposited in boiler tubes, pipelines, circulation systems, condenser jackets, heat exchangers, dies, and other equipment and thus result in corrosion and malfunctioning of the equipments.

We offer a range of water softeners that are primarily used to produce zero soft water. These are extremely functional and give quality end-results. The entire range of is also cost effective and highly reliable.

Features:

• Have highly acidic cat ion exchanger, which exchanges calcium and magnesium ions with sodium ions
  
• Are designed both for counter current regeneration with up flow rate as well as co-current regeneration with down flow rate
  
• Are designed for longer operating cycles, low regeneration cost
  
• Are suitable for residential, commercial and industrial use
  

Applications:

• Boilers and cooling water feed.
  
• Process water for water feed.
  
• Hospitals
  
• Hotels
  
• Homes
  
• Commercial & Institutional water plants
  
• Ice plants
  

The poor management of ground and other water resources have depleted and diminished the quality of water. While on the other hand, the growing population as well as heavy and unplanned industrialization has resulted in increasing demand for fresh and hygienically pure water.

We offer a scientific and technological solution for treatment of contaminated well water, polluted rivers, pond water and even seawater. Our mineral water system provides high quality, hygienically pure and abundant supply of fresh and clear water.

Features:

• Based on membrane technology that incorporates ozone technology
  
• Reverse osmosis refers this technology as desalination
  
• Complete stainless steel skid mounted unit
  
• Easy installation & commissioning
  
• Special factory layout for easy operation
  
• Various capacities available
  
• Easy maintenance

Methodology:

• Water is forced through the semi permeable membrane having a pore size of 0.0001 microns
  
• These membranes rejects both undissolved impurities like dirt, dust, bacteria, viruses and dissolved impurities like Cl, Fl, Pb, NaCl, pesticide and ions that lead to bad taste, color and odor in drinking water
  

Applications:

• System servicing restaurants
  
• Car washes
  
• Bottled water
  
• Beverage plants
  
• Hotel/motel
  
• Drinking water installations
  
• Greenhouses
  
• Ice manufacturing plants
  
• Medical & scientific laboratories
  
• Electronics
  
• Pharmaceuticals industries
  
• Boilers & cooling water applications

The natural resources of clean water are increasingly scarce or non-existent. The conversion of unusable Sea/Brackish water into usable water is one of the best ways to meet the increasing demand of fresh water. Desalination by Reverse Osmosis is one of the most widely accepted unique processes to treat Brackish, Sea and wastewater into high purity water for their ultimate applications.

We are the leading developer and manufacturer of industrial, commercial & domestic reverse osmosis systems. Our systems are even installed on off-share platforms, isolated island & hospitals rural villages many other remote places where safe, pure water is scarce.

Features:

• Easy to operate, maintain and monitor
  
• Is simple, dependable and is reliable
  
• Lower maintenance costs
  
• Lower regeneration costs
  
• Has higher production capacity to space ratio
  
• Is environmentally desirable
  

The major cost component in R. O. system is energy i.e. electrical power to operate the RO feed pump.

Advantages:

• Economiser - Low energy and operating cost especially when de-mineralising brackish water with TDS above 300 PPM
  

• Regeneration Free - Continuous operation requires no regeneration
  

• Pollution Free - No regeneration effluent are generated like that in ion exchange process
  

• Excellent Product Water Quality – Rejection of more than 97% - 98% of dissolved solids and more than 99% of un-dissolved organic substances
  

• Operator Friendly - Simple physical pressure driven process resulting optimum degree of automation with very less operating and monitoring efforts required
  

• Compactness - Very compact construction, low space required since acid – caustic bulk tanks and acid proof drainage system are not required as in D.M. Plants
  

• Flexibility - Modular design results into cost effective plant expansion with utmost ease
  

• Concentrator/ Separator - The same process can be used to recover valuable process material/metals/chemicals, dissolved in a solution.

Naturally available water is hardly suitable for industrial demands because of its dissolved organic and inorganic impurities. The impurities can be of various kinds like:

• Mineral
  
• Salts
  
• Compounds of Ca, Mg, Na, K & Fe
  
• Positive ions such as SO4, Cl, CO3, HCO3 and SiO2 etc.
  
• Negative ions
  

To make water suitable for industrial purposes high quality de-mineralizers are offered by us at affordable price.

Features:

• Are designed based on latest cost effective ion exchange technique of counter current regeneration.
  
• Offer a practical range of capacities and flow rates necessary to serve wide variety of applications.
  
• Consists of acid/alkali proof pressure vessel with internal fittings and ejectors, acid and alkali tanks
  
• Are available in various sizes having cation and anion exchanger unit
  
• To check the treated water quality at the outlet, conductivity meter is provided
  
• De-gasification unit is also provided to decrease the load on anion unit
  

Methodology:

• The units consist of two corrosion free pressure vessels internally connected in series
  
• The first column contains cat ion absorbing exchanger and second column contain an anion absorbing exchanger
  
• The water flow through the bed of cat ion exchanger then the bed of anion exchanger. Thus the system removes dissolved salts from water to a specified degree
  
• After using total exchange capacity of system cat ion and anion regeneration must be carried out
  
• The cat ion exchanger is regenerated with an acid and anion exchanger resin is regenerated with an alkali solution.
