Rice husk Ash (RHA) is a unique waste material which can be utilized to obtain valuable chemicals. This waste generated out of burning husk in Boilers, create huge pollution problem when dumped in open land or in water. Chemicals can be made by using such waste.
The technology of converting RHA to sodium silicate is a novel process developed by us where in the process is a semicontinuous and operated on closed loop process. There is no liquid, gaseous pollution. The cake obtained after filtration is taken care of by removing the retained product and pure Activated Carbon, with slightly low activation can be obtained and sold as by-product for rice bran oil filtration and allied industries.
We have two standard production line
10 MT per day
15 MT per day

Our technology is to produce highly dispersible silica and precipitated silica from rice husk ash based on zero waste chemical process using rice husk ash as feed and produces precipitated silica and other by-products. The technology can extract upto 70% silica from the ash. The technology has already been commercialized. The technology can produce silica for all major applications, including tires, rubber, footwear, paints, coatings, toothpaste, food & pharmaceuticals.
Rice husk ash is a leftover generated after using rice husk as fuel in industrial boiler and power plants. Every year more than 20 million tons of rice husk ash is generated globally which is landfilled or dumped in open grounds, affecting the environment negatively. Our technology will use the ash and extract the advanced grades of precipitated silica, including highly dispersible silica from it.
Highly dispersible silica is an advanced grade of precipitated silica which is used in energy efficient green tires to improve the performance of tires. It reduces the rolling resistance of tires while improving the grip. It results in improving the mileage of vehicles while reducing the greenhouse gas emissions from the vehicles.
The technology has various advantages over conventional precipitated silica production technologies. The conventional technology uses sand as a base material for silica whereas our process uses rice husk ash as a base material for silica. The technology can produce better quality silica as compared to existing conventional methods.
USES/APPLICATION :
Tires
Toothpaste/Oral care
Paints, Coatings & Inks
The raw effluent collected from different toilets and baths and floor washing etc. is allowed to flow into the collection pit cum grit chamber through a coarse screen and then allowed to flow to the next chamber.
From there the raw effluent (submersible) pumps will pump it to the reaction tank.
The biological process starts as the raw sewage it enters into the Packaged STP unit.
The first step is pre-aeration. Here the raw sewage is briefly aerated and allowed to over flow to contact aeration chamber. On the first impact with the contact media quoted with enzyme, the BOD load drops significantly. At contact aeration chamber, the waste is aerated, which helps grow MLSS (Mixed Liquor Suspended Solids). The MLSS overflows to sedimentation chamber for effective liquid â?? solid separation. The thick sludge is returned to the aeration chamber while the clear supernatant is allowed to flow out for disposal. As the sludge returns to aeration zone, it starts to get digested and tends to thin down. This is the specialty of this plant; it produces far less sludge as compared to any other sewage treatment plant.
The treated water may be discharged directly to any municipal drain without any further treatment or re-used after tertiary treatment, as per local regulations and re-use application.
Trusted by demanding customers like UN establishments, US Navy etc. due to the
Simplicity in design & performance
Toughness
Flexibility in seismic conditions compared to RIGID, CENTRALISED tanks.
Effective & satisfactory performance in unattended / unmanned operations
Nuisance freeness due to
no-odour
NO-SLUDGE REMOVAL conditions so no daily hindrance of manual sludge cake removals from filter press.
No-visible dirty water, as treatment takes place in sealed FRP tanks. So unpleasant visions are not created even when someone looks out from upper floors.
NO MOISTURE CREATED FROM OPEN SURFACES OF DIRTY WATER AROUND THE STP, WHICH USUALLY CAUSE SKIN DISEASES.
Powered by biological treatment process by means of engineered bacteria, these plants do not need daily dosage of harmful and expensive chemicals to operate.
Compact size, so less footprint. Further constructions can be easily done from above these tanks which help in better land utilization.
HINDRANCE FREE AS NO NEED FOR REGULAR DE-SLUDGING
Lesser number of rotating parts. No sludge recirculation pumps, filter press etc. required. Hence lesser energy consumption also.
