The INDION Fluidised Media Reactor (FMR) uses the attached growth process for waste water/sewage treatment and recycle. It incorporates a single tank unit, consisting of a bar screen chamber, specially designed floating media to facilitate the attached growth process, oxygen transfer through diffused membrane aeration, lamella settler and chlorine contact tank. The system is available in mild steel and reinforced concrete.
The FMR works on the same principle as the submerged fixed film process with only one exception - the media is not fixed and floats around in the aeration tank. The main advantage of this system over the submerged fixed film process is that it prevents choking of the media. This also avoids sludge recirculation. Compared to conventional technologies the FMR is compact, energy efficient and user friendly. It also allows flexibility in design of the reactor tank. The advantages of the INDION FMR are many –
Unique single tank design, no moving parts & easy maintenance.
Attached growth process, with specially designed moving media.
Compact and modular design.
Minimal pumping and chemical cost, low operating cost.
Flow rate for sewage treatment exceeding100 m3/d.
Applications of FMR include decentralised compact sewage plants for housing complexes, hotels, commercial complexes, industries and rural communities. It can also be used in industrial waste treatment in industries such as food & beverage, textile, pulp & paper, chemicals, pharmaceuticals, petrochemicals and dairy production.
Orders for the INDION fluidised media bed reactor for sewage treatment include Reliance India Ltd., ICC – Pune, SDM Technoengrs (Satyam Computers) and JK Cement, Rajasthan

nano generator
The day when you can charge your cell phone or iPod just by going for a stroll around the block could be a step closer, thanks to a "nano-generator".
About a year ago, Zhong Lin Wang of Georgia Tech in the US discovered that, when he disturbed zinc oxide nanowires, they gave off a tiny electrical current, a phenomenon called piezoelectricity. At the time, he had to use the tip of an atomic force microscope – a $250,000 instrument – to create about one-billionth of a watt of power. Not exactly energy efficiency.
But with his latest experiment, Wang has improved his design at least a thousand-fold. Using gold nanoparticle as seeds, he grew a small forest of 1-micron-high zinc oxide wires on a conductive substrate 2 millimetres square. Then he placed a saw-toothed electrode on top, which is designed to make contact with as many nanowires as possible. Finally, by rattling the whole thing with ultrasound, he found that he could generate a few microwatts of electricity.
That is still only a few millionths of a watt. But, by using ultrasound, the team demonstrated that they can activate the generator using any form of vibration. The movement of the top electrode disturbs the nanowires, providing a potential power source for anything that moves.
Furthermore, nanowires can be chemically grown on virtually any substrate, including metals, polymers, and anything else that could double as an electrode. The wires also precipitate from solution at 70°C, making them easy to grow under normal laboratory conditions.
Human implants
The generator suffers from a few key limitations, however. First, growing uniform nanowires is difficult – they are usually of slightly different height or diameter. As a result, in a generator containing many thousands of nanowires, only a few hundred or so successfully generate electricity when shaken, as they do not all make contact with the electrode. That hurdle must be overcome in order to charge large, power-hungry devices.
But Wang believes the nano-generator could be ideal for powering tiny devices, including those that may be implanted inside the human body. "Imagine self-powered force-sensors implanted in blood vessel walls, taking your blood pressure. Or generators in your shoes that can charge devices while you walk," he says.
Almost any device that could use a wireless, mobile power source could potentially use the nanogenerator, Wang says: "I have full confidence that within three years we will have something that is useful commercially."

HOMEOPATHY AND CHILD DISEASE
As far as babies and children are concerned if they are treated homeopathically they will develop strong immune power and can thereby resist all the diseases. All the acute conditions arising in this age group can be very well treated without any side effects and with immediate results. All the acute diseases like cold and cough, fever, diarrhea, lactose intolerance has best answers in homeopathy.
For cold and cough in new born babies a mixture of biochemic salts viz. Ferrum - phos and Kali - mur in 6x potency given by dissolving 12 tabs each in a cup of water and giving it every 2-3 hours will suffice. Even the above mixture can be used during fever in the initial stages. During this tender age Homeopathy is the best choice for babies. Nothing is suppressed and the immune levels of the baby thus slowly and surely go on increasing. There is a tendency among parents to immediately give medication even for minor problems. I very well understand their anxiety, but, is it advisable to suppress these bodily reactions? Are we giving enough time for the babies' immune system to react against these invasions?
I will narrate some of the most common conditions met in the children who can be best treated with homeopathy.
Late teething - remedies like Calc. Carb and Calc.phos
Late speaking - N.mur,
Late walking - C.carb, C.phos, Silicea,
Late closing of fontanalles - C.carb, C.phos.
Teething with irritability - Chamomilla, mag mur,
Diarrhea during teething - Chamomilla, Calc.phos, M.carb, Podophyllum
Growing pains where the child starts beating his legs during the sleep -
C.phos, R.tox etc.
Lactose intolerance - Ncarb, Lac defloratum, etc.
Rattling cough - Antim tart, N.sulph, Ars,.iod, Ipecac,
Grinding of teeth during sleep - Cina, Tuberculinum.
Erruptive fevers like Measles, Chicken pox - Bry, Puls, and Antim.tart
Coliky pains in babies - chamomilla, colocynth, sulphur
Tendency to eat pencils, mud, clay, etc - C.carb, Nit acid, C.phos.
My experience of treating babies for last 22 years is that - those babies suffering from skin eruptions with a Family History of Asthma if treated with orthodox medicine the skin eruptions become suppressed and these babies' starts suffering from Asthma. Therefore it is usually better to treat these skin infestations during the early childhood days.
For falls and bruises remedies like Arnica, Calendula comes in handy. Arnica has a tremendous anticoagulation property so if given immediately after a fall it will remove the extravasations of blood and also reduce the soreness. These above stated are some of the common condition met in children and babies. Also Epilepsy, bedwetting, night terrors, somnambulism, can be benefited with homeopathy.
