The Challenge / Concern: Aluminum sulphate is the best coagulant in terms of efficiency and cost. Occasionally it fails to give proper results due to its narrow operating range. Though theoretically it has the acceptable operating pH range of 5.5 to 7.8, its typical range of optimum performance in common ambient temperatures is of pH …

The Challenge / Concern: Low grade heat (water at 70-90oC) is wasted at energy intensive plants. Electrification of such low grade heat is not feasible by conventional routes such as stirling engine, thermoelectric, thermoacoustic etc. A more efficient device was desired which would have lesser dead work and wider compliance for variation in source and …
The Challenge / Concern: Fly ash is the material of global concern produced at the numerous coal fired plants. Value added product with engineering rigor was desired that would consume significant quantities of fly ashes of varying composition. A technology was requested with such anticipation. Brief (and non-confidential) Solution Aerators are the porous and sturdy …
The Challenge / Concern: Water scarcity is a relevant threat to humanity. In spite of limited availability of fresh water, there are little efforts to recover spent water. Through blackwater deserves to be spent to dedicated water treatment plants, the greywater can be reused for similar purpose with the treatment at the source. Relatively compact …

The Challenge/Concern: Desalination has scope to satisfy water need of world, but it is too much expensive. An effective, feasible and cost effective technology is desired against the thermal and membrane desalination processes. Brief (and non-confidential) Solution Directional solvents offer an advantageous approach for water purification. Many medium chain fatty acids are known to be …
