Ultraviolet Sterilizer provides a safe means of water Purification, which has been a proven process for many years. This method is now widely recognized and accepted as the concern of bacterial contamination has increased.Commercial ultraviolet disinfection systems are specifically designed to treat microbiologically contaminated ground or surface waters. These disinfection systems offer a 4-log reduction (99.99%) in bacteria, virus and protozoan cysts (specifically giardia lamblia and cryptosporidium). This UV process is quick, simple, inexpensive and environmentally friendly as it does not add anything to your water and creates no disinfection by-products. The most ecological way of treating your water. 

Up-flow Anaerobic Sludge Blanket (UASB) is the most widely used high rate anaerobic system for anaerobic sewage treatment.   The influent is introduced at the bottom. It passes through blanket of the sludge before leaving the reactor. The sludge blanket mainly consists of inorganic particle with anaerobic bio-mass grown around it. Sludge blanket acts as a filter and helps in removing suspended solids. COD reduction takes by substrate reduction by bio-mass. Primary sedimentation is not required prior to UASB as inorganic particles itself are used as media in blanket formation. The treated wastewater is collected at the top of reactor. Bio-gas produced during the degradation is collected at top.   No energy requirement for aeration or mixing . Energy production by means of biogas. Low cost of operation and maintenance. The energy requirement in the UASB reactor is very low. UASB system generates energy in the form of bio gas which can be used for the production of electricity and which can make UASB plants self sustaining for power requirement. This system reduces the space requirement, which is a big advantage for developing cities. The production of excess sludge in a UASB reactor is very low. This reduces the load on the sludge treatment system. However, the sludge from UASB plant is very stabilized and can be used as manure. Final polishing pond can be used for fish culture, which can be source of revenue.

Ultrafiltration (UF) is a pressure-driven barrier to suspended solids, bacteria, viruses, endotoxins and other pathogens to produce water with very high purity and low silt density. Typically, ultrafiltration will remove high molecular-weight substances, colloidal materials, silt (SDI), and organic and inorganic polymeric molecules.  It serves as a pretreatment for surface water, seawater, and biologically treated municipal effluent before reverse osmosis and other membrane systems. SHIVAM’s Ultrafiltration is a separation process using membranes with pore sizes in the range of 0.1 to 0.001 micron.

TUBE SETTLER is the most effective and alternative to the conventional sedimentation process. And, unlike the sedimentation process that demands a great deal of today's valuable space, the compact TUBE SETTLER is not marely a great space saver but helps cut down civil engineering costs substantially. Multiple tubular Channels-inclined at an angle and adjacent to each other-separate the suspended solids from water or any other liquid effluent. Individual tubes are continuous and smooth to minimise mixing of currents within the tube. The configuration and shape of each tube is design to obtain a low Reynolds number and laminar flow conditions for rapid accumulation and settlement of solids through the tubes. The high surface area of tubes enabling substantial improvement of settling capacity.

Think of the perfect swimming pool and visions of sparkling water and happy swimmers likely dance in your head. Keeping this scene intact involves taking the proper steps to sanitize the pool and prevent any health or aesthetic problems. The water will then remain clear of algae, free of disease causing pathogens and users won’t complain about red eyes or chlorine smell.  To keep this intention in our mind SHIVAM has provided you following solutions to keep your swimming pool clean:   For swimming pool filtration first we use sand filter to remove smallest debris and sediments from your water which comes in pool through human contact and other modes like rain and air. Basically, water flows into the top of the filter housing and makes its way down through the sand bed where the sharp edges of the sand catch the dirt. Sand filters certainly are efficient enough to keep just about any pool clean if we provide it maintenance properly .Maintenance means backwashing where the flow of clean water is reversed back into the filter. To enhance the filtration, we normally use Alum and /or poly electrolyte in the feed to the sand filters.

Sequencing batch reactors (SBR) or sequential batch reactors are industrial processing tanks for the treatment of wastewater. SBR reactors treat biosolids, sewage, sludge or other output from aerobic or anaerobic digesters in "batches."   The Sequence Batch Reactor (SBR) cleans the wastewater in one or more batch reactors according to a predetermined sequence of operations. The system performs equalization, aeration and clarification in a single batch reactor. Usually the Pipelife SBR system consists of at least two tanks. In this kind of configuration the first tank – the settlement tank – is used to retain the non-solvent particles. Because of their physical characteristics the non-solvent particles are discarded at the bottom of the settlement tank. The rest of the wastewater is conveyed to the second reactor by the pump on the reactor unit – the Swimmer Unit into the second tank – the SBR.

Rotating biological contactors (RBCs) is a remediation technology used in the secondary treatment of wastewater. This technology involves allowing wastewater to come in contact with a biological medium in order to facilitate the removal of contaminants. There are several different designs now available, but in its simplest form a rotary biological contactor (RBCs) consists of a series of discs mounted on a shaft, which is driven so that the discs rotate at right angles to the flow of settled sewage. These rotating biological contactors offer many advantages like: The capability of handling a wide range of flows. Low power requirements Low sludge requirements Excellent process control. Maintenance and housekeeping requirements are minimal. Only basic operator skills required.

Pressure sand filter is highly recommended for the removal of suspended & visible impurities like sand, dust particles & heavy metals etc.PSF is an ideal solution for the systems with high sediment, silt, sand, and turbidity.A typical pressure sand filter consists of a pressure vessel - this could be either vertical or horizontal-fitted with a set of frontal pipe work and valves, graded sand supported by layers of graded under bed consisting of pebbles and silex, a top distributor to distribute the incoming water uniformly throughout the cross section of the filter, and an under drain system to collect filtered water. Fig shows the arrangement of a vertical and horizontal pressure sand filter.

HYDRO PNEUMATIC PRESSURE BOOSTER SYSTEM consists of an automatic pressure controlled pump and pressure tank, which contain an air filled polyether-urethane (PEU) bladder. The water gets pumped in this tank that compresses it and pressurizes the bladder, which in turn maintains the desired pressure within the whole water piping and fixtures.   The method of reducing stating current and inverter loading is to vary motor speed. Centrifugal pumps follow a set of physical laws known as laws of affinity. One of them states that states that the power required to run a pump varies as a cube of any change in speed. If one reduces the normal running speed of 1 HP Pump by 50% only 1/8 HP is required to run it at the lower speed. Even a reductions result is substantial power reduction. An AC electric motor’s speed is varied by changing the frequency of the power supply. AC power in the US is supplied at 60 Hz. With a device known as a variable frequency drive, the supply frequency can be varied 0 to 60 Hz. By starting the motor at lower frequency and ramping up to full speed over a period of a second or so, starting current is greatly reduced. Another advantage of this controlled pump is that their speeds can be controlled automatically to provide constant pressure during varying flow conditions. A simple pressure transducer, connected to  the VFD, monitor pump discharge pressure & varies motor speed, thus maintaining pressure as demand varies in addition to providing nearly constant reducing the pump when demand decrease.       Industrial Water Distribution Systems Hospitals, Hotels Restaurants and individual Bungalows Multistoried Buildings Commercial complexes High rise Building & Residential societies irrigation/Foundation systems Boiler feed/DG Set/Feed/Cooling Tower/HVAC systems and all machinery where water pressure is required Fire Fighting Systems Big Townships Municipal Water Supply Systems for large scale application Car Washing/Automobile/Machinery for cleaning Applications

Fluoride is very common element, found in earth’s crust. It exists in the form of fluoride in a number of minerals like fluorspar, cryolite and fluorapatite. Fluoride enters in the aquatic system in the dissolved form through industrial discharge form through aluminium industries, phosphite industries, coal plants etc. Higher concentration in drinking water can affect the health adversely. The World Health Organization (WHO) guideline for fluoride is 1.5 mg/liter in drinking water. As per IS 10500 standard the desirable limit for fluoride is 1 ppm and permissible limit is 1.5 ppm in drinking water. Health Hazard Above 2 mg/l – Gives chalky white appearance to permanent teeth Above 4 mg/l – Causes dense and brittle bone condition, known as Osteoporosis and Skeletal Fluorosis.

An expanded granular sludge bed (EGSB) reactor  is a variant of the UASB concept. The distinguishing feature is that a faster rate of upward-flow velocity is designed for the wastewater passing through the sludge bed. The increased flux permits partial expansion (fluidization) of the granular sludge bed, improving wastewater-sludge contact as well as enhancing segregation of small inactive suspended particle from the sludge bed. The increased flow velocity is either accomplished by utilizing tall reactors, or by incorporating an effluent recycle (or both). A scheme depicting the EGSB design concept is shown in Fig. The EGSB design is appropriate for low strength soluble wastewaters or for wastewaters that contain inert or poorly biodegradable suspended particles which should not be allowed to accumulate in the sludge bed.

Electrodeionisation or EDI, is a continuous and chemical-free process of removing ionized and ionizable species from the feed water using DC power. EDI is typically used to polish reverse osmosis (RO) permeate and to replace conventional mixed bed ion exchange, which eliminates the need to store and handle hazardous chemicals used for resin regeneration and associated waste neutralization requirements.
