The effects of water quality can often be overlooked, but as water is the most common solvent used in laboratories. Its quality is key to getting the expected and not ruined results. Similarly using poor water quality in a healthcare environment or in clinical diagnostrics can potentially be life threatening. Understanding the importance of water is critical.
Internationally recognised water quality standards define the different types of water quality .
Achieving the correct water quality depends on selecting the correct purification technologies and a system design that accurately measures and monitors contaminants. Producing pure water is only part of the equation; validating quality, storing water and maintenance are also key to ensuring you have the water quality you need.
Having achieved high purity water the challenge is to keep it pure and to do so with the minimum operator intervention. The key is system design with attention to detail – the use of a well proven design with tried and tested components such as finer 0.05µm filters to give the extra level of protection against smaller particulates. Experience with all types and scale of water purification systems has demonstrated the need for periodic recirculation of clinical grade water through the purification technologies. Using any type of reservoir will lead to bacterial growth. Recirculation through an in-line filter and germicidal UV light will remove bacteria enabling a very low steady–state level to be achieved. This will also minimize further bacterial growth by reducing the organic matter available. Relying solely on point-of-use filters can allow a microbiological “soup” and extensive biofilm to grow within the system with only a single barrier to prevent serious product water contamination. Rapid monitoring of the effectiveness of such a barrier prior to use is not possible. Recirculation is recommended by CLSI – “recirculation should include enough water purification processes to maintain a consistent level of purity in the loop”- as is periodic sanitization - “biofilm will develop…and sanitization is the only way to combat it”, “Sanitizing storage and distribution systems must be performed often enough to prevent a significant build-up of biofilm”. It is essential to make sanitization as easy and as least-disruptive as possible.As well as direct interference effects, bacteria are a source of a range of by-products, such as alkaline phosphatase, endotoxin, RNase and DNase, which can affect assays in their own right. Their presence is a result of poor bacterial control and they are best minimized by maintaining very low bacterial levels by active recirculation. For example, a bacterial level of <1CFU/ml will give about 0.5 micro-units of alkaline phosphatase per litre – far too low to interfere with assays.
Because of the dependence of high volume analyzers on a continued supply of high quality pure water, the purification system should incorporate an emergency bypass to allow controlled shut-down in the event of a problem and, preferably, contingency measures need to be in place, such as duplex water units and duplex analyzer feed loops to each analyzer. As well as needing pure water to feed analyzers there are a variety of other requirements for clinical grade water in the clinical laboratory.
EDI (ELECTRODEIONIZATION) WATER TREATMENT SYSTEMS
We are a leading and well recognized names in the field of providing solutions for Electrodeionization (EDI). It’s a water treatment technology which utilizes electrodes for ionizing water molecules as well as separating dissolved ions (impurities) from water.
Some of the industry areas where this technology is preferred include:
• Power generation
As a technology, EDI combines ion exchange resins and ion-selective membranes with direct current which assist in effective removal of ionized species from water. Further, EDI process helps in producing industrial process water of high purity by using less than 95% of chemical products that are used in conventional ion exchange processes. The other advantage of the system is that EDI system membranes and electricity effectively replace acid and caustic chemicals that were used in old processes for water treatment.
EDI as a technology is useful for applications needing constant and economical removal of water impurities without any dangerous chemicals involved. Some preferred application areas are:
Reuse of residual water in food and beverage industry
Boiler Feed Water
Some of the advantages of these systems include:
• Removing dissolved ions up to 5-17 M?-cm, TOC <20 ppb
• No involvement of harmful chemicals for regenerating resin
• Designed to deliver reliable, low-cost ultrapure water solutions with up to 18 MOhm-cm resistivity
• Systems designed to effectively remove residual salts and ionizable aqueous species like silica, carbon dioxide, ammonia
• Operating without chemicals, these systems are designed to achieve 95% water recovery
• Reduce energy and operating expenses
• Reduction in environmental waste
• Stable continuous performance with lower operating costs

In the filtration process, Ultra-Filtration (UF) utilizes trans-membrane pressure differential for separating particles as per molecular weights. The raw water particles are smaller than pore of UF membrane get permeate and particles larger than UF membrane pore size get separated as concentrate under applied pressure.
UF Membrane Construction:
It is asymmetric semi-permeable membrane made using high molecular material
• The hollow fiber tubes are covered by micro-pores that allow solutions flowing in/out the membranes under influence of pressure
• UF membranes have pore sizes from 0.1 to 0.005 µm for different applications
• Normally, this process is utilized in removing-
- High molecular-weight substances
- Colloidal materials
- Organic/inorganic polymeric molecules
The noted advantages of UF Filtration membranes include:
• Require minimum pumping energy, thus providing saving on energy
• Offering chemical resistance over wide PH range
• Easy to operate & maintain with low investment costs
• Recovery ratio up to 98%
Some of the industries these are used in include:
• Surface Water Clarification
• RO Pre-Treatment
• Waste Water Treatment
An RO water purifier uses membranes to purify water. The membrane in an RO water purifier is what makes an RO water purifier different from other types of water purifiers, because the membrane in an RO water purifier can remove dissolved chemicals from water. This is why an RO water purifier is considered the best type of home water purifier.
Bacteria and Viruses in water and the diseases that they cause are what worry most people and the reason why most buy a water purifier. More dangerous than the bacteria and viruses in water is the dissolved poison chemicals in water like Arsenic. These are silent killers with no symptoms for years and when health problems start showing, it is usually too late to treat it. Of all types of home water purifiers available, only an RO water purifier can get rid of Arsenic and other poiso chemicals in water. That is why we say that with an RO water purifier fitted in your kitchen, you can rest assured that you are getting safe drinking water at homeThere are mainly two different types of Reverse Osmosis RO water purifiers available in India: one is an undersink RO water purifier and the other is a wall mounted RO water purifier. Pictures of these two types of RO water purifiers are shown below. Both are storage type RO water purifiers since they have a storage tank for purified water, and purified water will be available even when there is no electric power in the house.
DM plants comprise of the following specifications:
The water distribution loop must be made from sanitary materials of the same characteristics as those of the storage and distribution skid. The main characteristic is that they must be 100% drainable so they will be designed with gradients towards the points of use so that in the event of a shutdown of the installation no water will be retained in the loop. As for fluid mechanics, the water must circulate in the pipe in turbulent flow (speeds over 1.2 m/s and Reynolds number over 10,000 are advisable) in order to minimise risks of contamination which would occur if it were to circulate in laminar flow, a positive pressure must also be guaranteed in the return to the tank (1 bar). For this, various instruments will be used such as a variable speed drive for the pump, pressure probe and flow meter.
The loops must be correctly insulated in order to minimise heat loss, thus achieving considerable energy saving, and in clean rooms this must be of stainless steel .
The fixing of the installation must be made using sanitary pipe hangers covered with polymer material (according to the temperature) to minimise the risk of external corrosion of the pipe.
The main elements of the distribution loop are:
