Self cleaning (auto backwash) filters combine the advantages of high quality filtration from different water Sources (Sewage, Reservoirs, River, etc.) with self cleaning features, where the flow is uninterrupted during the filtration process. The filters are designed for use in a wide range of industrial, municipal and irrigation applications.The main element is made of stainless steel with a large filtration open area for water flow in order to Withstand high dirt load and pressure. Cleaning of the screen is performed once the pressure loss across the filter has reached the present value (up to 0.5 kg/cm2) The filter is equipped with a coarse screen that protects the finer screen from stones and larger particles. The flushing valve opens and pressure is released from the hydraulic piston, then water flows outside through the flushing valve. Pressure in the hydraulic motor chamber and the dirt collector is significantly lowered. The dirt collector nozzles movement and rotation cleans the screen's entire internal surface. The flushing cycle takes 10 seconds. The flushing valve closes at the end of the cycle and the filter is clean. During the cleaning cycle, the filtration process Remains uninterrupted. Hence you will get filtered water continuously.

Rubber Lined Vessels, Tanks, Piping etc.Rubber lining : The process of rubber lining is divided in to the following steps. Preparation of the base surface. Preparation of rubber sheets. Application of the rubber sheets on the metal surface. Vulcanization Testing & Inspection Surface Preparation :This is very important process for rubber lining. The surface of the metal must be free from oil, paint, scales, rust etc. this is generally removed with the help sand blasting/ shot blasting. After the surface is cleaned, adhesive or bonding agent is applied to surface. Two or three coats are applied, as adhesion is an important process for rubber lining.Preparation of rubber sheets :The rubber compound is manufactured as per the requirements after looking in to the chemical and other conditions of the process. Rubber sheets are made on calendar machine in different plies. Lining up to 6 mm thickness can be applied in single layer. If the thickness is more, it is applied in 2 or more layers. For Pipes & fittings Extruded rubber tubes are inserted in the Pipes.Application of rubber sheets :Un vulcanized rubber sheets, which are prepared on the machine are applied on to the adhesive coated, half dried surface under slight pressure of hand or with a metallic roll as well as with the help of various lining tools. We have to ensure that no air gets trapped between the metal surface and rubber sheet. Joints are made levels and joind with help of knurling tools.Vulcanization :By and large vulcanization is carried out in an auto clave. This is the process by which rubber changes from plastic state to elastic state. The temperature and pressure depend upon the rubber compound and thickness of lining. Large size equipments, which are rubber lined at site, are vulcanized By open steam as well as by hot water curing, the temperature is maintained to get the rubber cured and for this method special compound of rubber is to be manufactured for this process.Testing and Inspection :All the rubber-lined items must be tested before and after vulcanization. This is to ensure that they are free from faults, Which might cause failure of the equipment. Visual inspection in good light is carried out to check mechanical damages blisters and poor joints. There after spark test with a high voltage is carried out to check mechanical damages, pin holes, blisters and poor joints. Hardness test is MUST for rubber lining. Knocking test is also carried out by an experienced hand with the help of Wooden hammer to check whether there is any poor bonding.Protection of rubber lining equipments :The vessel should be stored away from sunlight or it should BE covered by tarpaulin or some, other device.

A Typical two-bed DM Plant consists of two MS Rubber lined Pressure vessels connected in series along with its internal fittings. The first unit consists of high capacity strongly acidic cation exchange resin, which converts positive ions of salt and replaces them with hydrogen ions to form respective acids, which are absorbed in next vessel by strongly basic anion exchange resin. The water obtained by this process shows conductivity less than 20 µ S cm at 25 Deg C and total dissolved solids less than 10 ppm.Further high purity water can be achieved by Mixed Bed Deionisers, which are designed to produce high purity treated water. They can be used as polishing units after two bed DM Plant to obtain high purity water. Mixed Bed Deionisers are single column units, filled with strongly acidic cation and strongly basic anion exchange resins mixed together.

They can be used as polishing units after two bed DM Plant to obtain high purity water. Mixed Bed Deionisers are single column units, filled with strongly acidic cation and strongly basic anion exchange resins mixed together.   There are four distinct stages in the operation of Deionisers Service Backwashing Regeneration Rinse/remix   Service :In the Service cycle the water enters the vessel and passes through the Resin bed of the respective exchanger.Backwashing : After the resins are exhausted, the bed is backwashed. Backwashing is carried out by a uniform upward flow of water through the resin bed. The backwash step expands the resin bed releasing any entrapped particulate matter & removes the channeling in the resin column if occurred during the service cycle. Regeneration : When the ion exchange resins loose all the exchangeable ions, they require regeneration to restore them back to hydrogen or hydroxyl form depending upon whether they are cation or anion resins. To achieve this 4 - 5% concentrated solution of Hydrochloric acid is used for cation resin and a 4% - 5% concentrated solution of caustic soda for anion resin.Rinse : The final stage of regeneration is to rinse the resins of excess regenerant

Activated Carbon Filter is the most common method of treatment for dechlorination and removal of colour, odor, Organic impurities & Residual chlorine from water, through adsorption of the compounds that cause these problems.Activated Carbon Filter operates through adsorption. Adsorption is directly related to the surface area of the media. This great surface furnishes a huge adsorption area for organic as well as chlorine molecules to attach themselves. This intermolecular attraction between the carbon surface and the substance that is being adsorbed can be altered by increasing the density of the carbon or by reducing the distance between the carbon surface and the substance being adsorbed.
