Defining Innovative Water and Solar Technologies

Our Plants are simple and space-saving, cost-effective and highly efficient in removal of Arsenic, Iron and various other contaminants from water. It is a state of the art technology and by far the best method of all the available technologies out there. There is no wastage of water. This system is suitable for catering potable water to a larger population. We can also provide SCADA enabled treatment systems on request. Some AIRPs manufactured by us include those in Jasaikathi, Mollahati, Paschim Panchberia, Aturia, Magurali etc. The spent media  is non toxic and non hazardous. However, we also take care of safe disposal of spent media/waste.

Being simple yet highly effective is our motto in delivering world class technologies at water purification. The waste toxicity from these plants belong to class IV which means it can be disposed off along with domestic wastes. However, we take care for safe disposal of the waste. There is no wastage of water. We also provide SCADA enabled treatment systems on request.

CPPs provide the same effectiveness as that of AIRPs or FRPs and is installed for catering potable water to a smaller population and hence the name “Community” purification system. It has the same characteristics as those of AIRPs and FRPs except that these are smaller in size. Process automation may be provided on request.

Based on reverse osmosis technology for purification of water. The rejected water in our systems is recycled.

Ultra filtration technology has been utilized in some of our drinking water units.

We can also provide Water ATMs which is with easy operation and safe water for “on the go” people.

Solar Power is now the most sought after alternate source of energy which is non-polluting. Hence we would also be venturing into creating both off-grid and on-grid power supply systems to lend our support for a greener future.

A green and clean way to help save our Mother Earth, we have introduced solar power into irrigation systems.

Solar Street Lights may be one more way at curbing out usage of polluting energy sources and paving way for the green.

We have covered installation of Water Supply Systems with the ability to be completely driven by Solar Power all over West Bengal. As already mentioned, our systems are simple yet effective and reliable to function even in the most rural areas requiring almost no human intervention.

Our future scope is also to dive into treatment of Effluents and Sludge for a better and greener future with our innovative technology.

Our Future plans also consist of providing support to others in terms of our Technology and other Projects. It may be mentioned that we have got associations with the best technology providers of the world in the field of water, waste water, effluent treatment, steel and mining projects including those from Germany, England, Italy, Russia, Ukraine, USA, etc.

Cheap & Affordable

Production cost of Arsenic free treated water is very low compared to conventional systems prevalent in the market.

All Gone in One-Go
  • Effectively removes suspended as well as dissolved constituents of water and Turbidity besides As, F, Fe, Mn, heavy metals, phosphate etc.
  • Also improves other water quality parameters like odour & colour resulting in ancillary health and aesthetic benefits including disinfection of microorganisms
Product Quality

All contaminants are much within acceptable limits (MCL) as per IS and WHO.

Compact & Space Saving

Space required by our systems is far less (1/8th) than those required by conventional systems of similar capacity. Thus saving large pieces of agricultural land from wastage.

No Wastage of Water

Backwash Water is recycled

Leaching?
  • No separate Oxidation Chamber is required and hence there is no risk of Arsenic leaching with Oxidation Media.

Plus, Arsenic in the solid waste is in immovable form meaning no leaching from anywhere.

Spent Solid Waste Characteristics and Disposal issues?
  • Spent Solid Waste is minimum, NON-TOXIC and Non-Hazardous (See: Toxicity Characteristics)
  • As is contained in immovable form, i.e., no leaching risk.
  • Can be disposed off as per environmental norms
Saves Energy
  • No secondary pumping is required. Hence there is no separate electricity cost for the treatment units as existing source water feed pump head is utilized in the process
Modern Technology – User-friendly

Safe and dependable, as already have come across from the above points, it is also easy for the local operator to operate, i.e., no special skill is required (nominal training to villagers) which is the true motto of being modern: user-friendly for all.

Low O & M cost

O & M is easy and hassle-free with very low cost.

What Gets Removed?

  • Suspended & Dissolved Constituents
  • Arsenic
  • Fluoride
  • Iron
  • Manganese
  • Phosphates
  • Heavy Metals, etc.
  • Microorganisms
  • Turbidity
  • Odour
  • Colour

Toxicity Characteristics of Spent Media and Back Wash Residue for AIRP

  • Our comprehensive technology removes arsenic, iron and other undesirable constituents together in our system.
  • The system includes oxidation (performed under the influence of active substances) of As(III) to As(V) which reduces arsenic toxicity ten times at once.
  • After oxidation, the received As (V) is removed using the method of formation of water-insoluble compound.
  • This sediment is insoluble in water and natural organic acids (for example, humic), i.e., non-leachable and non toxic and non hazardous.
  • This sediment can be disposed off as per environmental norms.

Advantages of our Fluoride Removal Technology over Others:

Mentioned are some ineffective methods widely adopted for Fluoride Removal and how our Technology (Contact Sorption) is far better and effective than the others.

  • Costly and not suitable for community drinking water system.
  • Requires frequent regeneration of the resin
  • Regenerant is extremely toxic and very problematic for disposal.
  • Complex process
  • Costly
  • Require skilled operators.
  • Not suitable for implementation in rural areas.
  • Low Removal Capacity
  • Too costly
  • Frequent regeneration required.
  • Regenerants are toxic and their disposal problematic.
  • Cost-effective
  • Easy operation for village operator
  • Affordable and suitable for community drinking water supply systems.
  • No regeneration required.
  • Wastes are Non-Toxic, Non- Hazardous and can be disposed off with solid domestic wastes(SDW).

Toxicity Characteristics of Spent Media and Back Wash Residue for FRP

  • Insoluble solid wastes (metal hydroxide and fluoride alumina hydrate) generated during the process of water treatment can be separated by filtering.
  • The wastes generated after purification belong to the II (second) category or in other words to the IV class of hazard (see table: Hazard class, provided on the right for your reference; the highlighted text indicates the class to which wastes from our units belong.) and are subjected to storing along with solid domestic waste (SDW).
  • Liquid insoluble wastes: Absent
  • Gases generated during purification process: Absent.
