B. 1 W-000052 WATER Grundfos Pumps India Pvt Ltd The Grundfos AQpure water treatment system produces potable water by filtering bacteria, viruses and particles from raw source water, providing a reliable and affordable water to the communities. The water treatment is based on ultrafiltration (UF) technology. Standardised treatment modules can be combined according to the specific raw water quality on site to deliver a complete water treatment unit. There are 11 different module options available with this unit which are briefed below. Self-cleaning pre-filter: The pre-filter comes with a mesh size of 100 micron. As such, it removes all bigger particles to protect the UF membrane and prolong service intervals. The pre-filter is automatically backwashed together with the UF membrane. The unit also includes a pressure sensor to initiate separate pre-filter backwash or signal that manual cleaning is needed. Standard UF membrane: The ultrafiltration membrane module consists of a hollow fiber, dead-end, outside-in membrane PVDF module with a pore size of 0.03 micron. The filtration is driven by a 1.1 kW Grundfos CRNE, stainless steel pump with a variable speed motor. The control strategy is parametric and automatically adapts to changing water qualities in order to prolong service intervals. Air scouring: The air scouring module enhances the efficiency of the UF membrane backwash by inducing air bubbles before the backwash. This physical cleaning of the membrane reduces chemical consumption and prolongs service intervals. The air scouring module is driven by a 0.75 kW compressor. The air scouring module also enables testing of membrane integrity by a semi-automatic pressure decay test. Chlorination: This module enables disinfection by adding chlorine to the treated water. This prevents bacteria or viruses from re-populating the water after treatment. The chlorination module also allows chemical-enhanced backwash to reduce biofilm growth on the membrane surface. The chlorine is dosed by a Grundfos SMART Digital dosing pump that includes an integrated flow meter to allow accurate flow proportional dosing. Internal CIP: This module enables chemical cleaning of the UF membrane when it cannot be cleaned hydraulically or physically. Chlorine is dosed into the closed circuit and circulated to dissolve fouling on the membrane. This automated procedure maintains water production capacity and prolongs service intervals. The CIP module utilises the chlorination module and a self-priming circulation pump. Level sensing: The level sensing module consists of an external level sensor which can be added to a locally sourced external water tank. The level sensor sends out an analogue 4-20 mA signal which is used to control the water production of the complete system. Activated carbon filter: The activated carbon filter performs final polishing of the treated water. The AC filter is used to remove certain chemicals, particularly organic chemicals, from the water. The AC filter is also used to remove substances that give water an objectionable odour or taste, such as hydrogen sulphide or residual chlorine. The module is backwashed and rinsed in an automated sequence. UV disinfection: The UV disinfection module can be added as a final disinfection step to protect water consumers against the risk of bacteria and re-growth of viruses. The 70 W UV lamp is designed for easy replacement with a minimum lifetime of 9,000 operating hours. The module includes a light intensity sensor which monitors that the lamp emits the specified UV dosage and sends a warning signal if it does not. Distribution: The distribution module allows the treated water to be pumped to an external storage tank. It is an automated process that uses the backwash pump. The module includes a mechanical measuring device which sends out a pulsed signal so that the total amount of produced water can be documented. Remote management: The remote management module connects the unit to an internet-based data management programme. The data management system provides real-time operational status of the connected systems. Warnings and alarm notifications can be broadcast as emails and text messages. Solar package: The solar package module enables solar power to reduce the operational cost of running the unit. The solar module includes a bi-directional inverter of 2,000 VA, 1,600 W with an integrated charge controller so that the unit can be powered by a combination of grid and solar power. The module also includes two 200 Ah gel batteries so that the unit can produce at least 6 m3 water on battery power. Technical Data: Water production - 0.5 to 2 m3/h Power supply -200-240 V, 1-phase, 50 Hz Control interface - PLC based 7" touchscreen Weight Empty - 400-615 kg; Filled: 750-1165 kg Dimensions - 1475 mm X 1464 mm X 2296 (L X W X H) Key Features: Easy to install Optimized adaptability Minimal downtime and optimal reliability Remote management Self-adaptive control 1 23/07/2019 3:15PM PDF

B. 7 W-0000181 WATER Sre Senthil Engineering Company (SENCO) Silver Ions Ag2+ are produced from 99.9% pure Silver Electrodes by passing a calculated amount of current. This is produced according to the setup in the control panel, which in turn is as per actual flow. The entire water from the pump is made to flow through the electrode chamber ONLINE where it gets totally silver ionized. How it works? Silver ions produced in our system are positively charged and micro-organisms are negatively charged. There is an attraction between silver ions and micro-organisms. The silver ions disable the enzyme that micro-organisms depend on to breathe and thus kills them. Silver is effective because of its capabilities of interfering with DNA production and accelerating the death phase of bacteria and viruses. Because of the charge in ions, they repel each other and are always in suspension. As their size is small, they have a large surface area of silver per unit volume of silver. This small size with its large surface area to volume ratio enables the surface chemistry of silver. Unique features: Fool proof and reliable(starts when pump is switched ON) Longer residual effect (for about 48 hours) No carcinogenic by-products Instant tests using field test kits Online stainless steel water chambers Light weight and compact Wall mountable Kills bacteria and algae No smell No change in taste Dosage well within WHO,EPA and BIS limits No corrosion, hence longer life Cheap running cost CSIR NEERI, Nagpur appraised technology 4 18/06/2021 3:36PM PDF
