Drinking Water

The main purpose of disinfecting drinking water is to kill bacteria and virus which cause dreaded diseases.

The major disinfection methods are:

Boiling – This is not always suitable as this method is expensive, fuel intensive and does not offer protection against recontamination.
Ultra- Violet/ Reverse Osmosis /Ozone - These are also not always suitable as they are expensive and therefore not viable for the urban and rural poor. These processes do not leave any residual in water to prevent recontamination, hence not suitable for distribution networks.
Chlorine gas – Though it is suitable for disinfection, due to its dangerous and polluting nature, it does not find easy application in most places.

In a drinking water distribution network, water needs to be rechlorinated from time to time to prevent recontamination.

This rechlorination can be achieved through our Electrochlorinators.

Pristine Water Electrochlorination is an inexpensive, simple, effective and self sustainable method of providing safe drinking water to the people of villages and urban slums.

Food and Beverage

Pristine Water

Leaders in water treatment solutions using Sodium Hypochlorite Generators (SHG)

The food and beverage industry depends largely on chlorine for their disinfection needs. Chlorine is used in meat and poultry processing units for disinfection. Also, during the manufacturing of soft drinks, jams & fruit juices bio-contaminants from the raw materials like fruits & vegetables are removed using sodium hypochlorite. Further, the purification and disinfection of the containers in which these products are packaged is made possible by using chlorine. Poultry units use electrochlorinators for disinfection of the premises and for purifying their water supply. Fisheries also use electrochlorinators for disinfection. Dairies use sodium hypochlorite for sterilizing their equipments and general sanitation. On-site sodium hypochlorination is the most suitable method for this kind of disinfection as it is low cost, prevents recontamination and is energy efficient as compared to other methods.

Infection free Swimming pools

Bacteria and Infection free Swimming pools with our range of Pool Chlorinators

A swimming pool at home need not be a distant dream, says Rini Mukkath, and brings you three smart ideas

Imagine coming home after a hectic day at work and sinking into a pool in your backyard. It sounds like Paradise but a lot of us think a personal pool is wasteful, hedonistic and hard to maintain. That might not be quite true. Contrary to popular belief, you don't need to have a large backyard, waste water, or work hard to maintain a personal pool. “What many people think is a luxury can be accessible to all,” says Sowmya Narayanan of XS Real Properties. Here is a quick look at three common myths about home pools and why they need not be true after all.

1 # Pools waste water

This is a particularly potent bogeyman in water-starved Chennai. However, experts say you can easily avoid wastage if you adopt proper cleaning methods and keep your pool and algae free. “A little maintenance and safety measures are all that's needed,” reiterates Sowmya. Her company promotes pools with recycling plants, an amenity that is quite easy to add on. And if you have nightmares about having to replace the entire water in the pool every few weeks, think again.

According to M.C.Simon, managing director, Clearwater Pools, “Water in a swimming pool can be used for over four years; it just needs topping up from time to time”.

Nearly 90% of water loss in a pool occurs due to evaporation, so if you cover your pool, you can reduce this drastically. A pool cover also reduces the need for chemicals to keep it clean. “Only a little water is lost from spillage,” says Shrutika, an IT professional who recently installed a pool for her kids, who splash around and wet the deck area. What Shrutika did was put in granite decks that last longer.

She also added a little metal fence to reduce spillage and a plastic roof to reduce evaporation and keep the pool cool. “The covered pool in our project not only reduces evaporation but also provides privacy to our home owners,” says T. Raghunandana, Tangirala Infrastructure, who has just launched Ananta, a villa project in Thoraipakkam. And finally, when you clean your pool filters, empty the filter backwash on to your lawns or plants or even collect it for reuse. It's an excellent recycling method.

2 # Pools are tough to clean

A few common-sense practices and a little loving care are all that's really required for a clean pool. As far as possible, keep a cover on the pool. Second, keep a leaf net handy and skim off the top of the pool now and then. Next, sweep the deck clean regularly. Besides this, you need to clean the filters regularly. In fact, by keeping the pool and filters clean you can significantly reduce the rate of backwashing.

Some pool filters do not require frequent backwashing, as it may affect their efficiency. “As a filter collects dirt, its efficiency increases, so it's important that you don't backwash your system too frequently or the filter will never reach its full potential,” says Simon.

The commonest cleaning agent is chlorine, which is added to the water as granules that release chlorine into the pool continuously. You can also opt for salt water chlorination, where you add salt that turns into chlorine the minute it touches water. It's important to maintain the PH balance of the water. If imbalanced, it can lead to algae growth and if there is too much chemical, the water can get alkaline and cause rashes. “The ideal PH level for a pool is 7.2-7.4, as this doesn't affect the human skin and keeps the water sparkling clean,” says Simon.

And finally, keep vegetation and animals far away from your pool. Bird droppings and animal waste helps algae to thrive and you definitely don't want pool scum.

3 # Pools need huge space

One of the major hurdles to having a home pool has always been space. Shrinking floor spaces have meant that most people can't even dream of a pool at home. Welcome to counter-current swimming pools, also called smart pools. They work like treadmills and have a special motor in place that lets you swim against the current in a small space. This pool can be 10-15 feet in length but once you start swimming, it creates the illusion of an endless pool, much like how treadmills work. “We have installed smart pools in our villas,” says Vummidi Ananth, managing director, BBCL Sandshore, “and they also have UV inoders to keep them fungus free.” A pool right inside your home that allows you to do your 20 laps? Why not?
