Shiva Aqua Enterprises Ludhiana, Punjab

All membrane pressure vessels are manufactured by computer controlled filament winding machine and associated high precision processing equipments. With a team of skilled technical experts in the field of computer controlled machines, and all the state-of-art processing machines in-house, we offers a range of high quality membrane housings in various colours including white, blue and grey as per customers choice. We have designed our membrane pressure vessels 4" with internal diameter that is mirror finished to a tolerance of /-0.02 mm, which aids in easy loading and unloading of the membranes. The external surfaces are highly polished and coated with high-gloss polyurethane paints for UV resistance and excellent aesthetics. The end cap assembly comprises of a single piece molded seal plate and a 2 turn stainless steel locking ring; these features enables easy removal of end cap without any special tools.   All our pressure vessels are designed for a life of 10 million cycles and with burst pressure of 6 times the rated operating pressure. 100% of the pressure vessels are hydrotested at 1.5 times the design pressure before shipment.

Since it is not possible to carry delicate glassware out into the field for field tests, several companies/agencies/NGOs/Government laboratories have done a lot of work to bring out kits which use the titration principles but are light, can stand up to rough 'travel' and still give fairly accurate results.  These are field test kits which can be used anywhere and by anyone who can read the instructions. Titration involves using a chemical solution of a known strength in a burette to be added to a sample of water to be tested in a beaker/conical flask. A chemical indicator solution is also added to the water before titration. The solution from the burette is added to the sample in carefully controlled drops with the sample being continuously stirred. This addition is stopped when the colour of the sample changes. The burette reading taken after colour change is multiplied by a specific numerical factor.   This gives the quantity of the parameter tested for in the water in terms of mg/litre or parts per million (pm). All titration tests are colorimetric tests where a change in colour is an indication that the presence/absence of the parameter being tested had been ascertained.

The rotameter is an industrial flowmeter used to measure the flowrate of liquids and gases. The rotameter consists of a tube and float. The float response to flowrate changes is linear, and a 10-to-1 flow range or turndown is standard. In the case of Shiva Aqua Care rotameters, far greater flexability is possible through the use of correlation equations. The rotameter is popular because it has a linear scale, a relatively long measurement range, and low pressure drop. It is simple to install and maintain. Rotameter are named after ROTA, one of the European inventors of this flow principle in the beginning of the century. ROTA invented the rotating float, which is self-guiding and has less friction in the pipe so that a more precise measurement is possible.    The basic rotameter is the glass tube indicating-type. The tube is precision formed of borosilicate glass, and the float is precisely machined from metal, glass or plastic. The metal float is usually made of stainless steel to provide corrosion resistance. The float has a sharp metering edge where the reading is observed by means of a scale mounted alongside the tube. End fittings and connections of various materials and styles are available. The important elements are the tube and float, often called the tube-and-float combination, because it is this portion of the rotameter which provides the measurement. In fact, similar glass tube and stainless steel float combinations are generally available, regardless of the type of case or end fittings the application can demand, so as best to meet customer requirements.  The scale of the rotameter can be calibrated for direct reading of air or water, or it may have a scale to read a percent of range or an arbitrary scale to be used with conversion equations or charts. Safety-shielded glass tube rotameters are in general use throughout industry for measuring both liquids and gases. They provide flow capacities to about 60 GPM, and are manufactured with end fittings of metal or plastic to meet the chemical characteristics of the fluid being metered. The only fluids for which these meters are not suited are those which attack glass metering tubes, such as water over 90°C (194°F), with its high pH which softens glass; wet steam, which has the same effect; caustic soda, which dissolves glass; and hydrofluoric acid, which etches glass. The primary limitations of general purpose rotameters are the pressure and temperature limits of the glass metering tube. Small, 6 mm (1/4") tubes are suitable for working pressures up to 500 psig, but the operating pressure for a large 51 mm (2") tube may be as low as 100 psig. The practical temperature limit for glass rotameters is 204°C (400°F), although operation at such high temperatures substantially reduces the operating pressure of the meter. In general, there is a linear relationship between the operating temperature and pressure.
