As access to clean drinking water continues to be a challenge in many developing countries, Pristine Water has partnered with many Non-Governmental Organisations (NGO) in the development sector all over the world to provide clean safe drinking water to the Rural and Urban poor. Electro chlorinator, which is the flagship product of Pristine Water, is a system that can produce a strong disinfectant from common salt, water and electricity. In areas where electricity is unavailable, solar power is used. Pristine...
Drinking water sources such as groundwater, reservoir water, late or pond water are open to contamination and hence require appropriate treatment to remove disease-causing agents. Public or Municipal drinking water systems use various methods of water treatment to provide safe drinking water for their communities. The typical steps involved are Coagulation and Flocculation, Sedimentation, Filtration and Disinfection.
The amount of wastewater and effluent getting generated is steadily increasing with increased urbanization, economic growth and many other socio-economic factors. Today, nearly half of all the water that gets treated is wastewater. The primary concern of wastewater disinfection is the removal of pathogenic microorganisms. Secondarily, wastewater discharge should not contain compounds with environmental health impacts. While a chlorine residual is desirable in drinking water treatment, it is not desirable in...
Cleanliness and Disinfection in The food industry are very critical requirements. Disinfection is the process by which microorganisms are killed so that their numbers are reduced to a level which is neither harmful to health nor to the quality of perishable goods. Disinfection is required in food plant operations, where wet surfaces provide favorable conditions for the growth of microbes.
Recreational Water lllnesses (RWI), originate from swimming pools, hot tubs, water parks and other man-made water features. They are also spread through freshwater ponds and lakes, and even in some saltwater environments. Bacteria that cause an RWI include Cryptosporidium, giardia, shigella, E. coli and norovirus. All these organisms thrive in non-chlorinated water. Exposure to an RWI can cause mild to severe diarrhoea, gastrointestinal distress and eye, ear and skin infections. Chlorine is added to water in...
A huge percentage of populations worldwide are affected by infections acquired from hospitals. Infections generated from hospitals are a major challenge to public healthcare systems. In order to avoid the risk of infections it is necessary to ensure the hospitals are properly disinfected and sanitized. The most common methods of sanitizing is with the use of disinfectant solutions. Contaminated surfaces are sources of infections and require care of high level of compliance with recommended hand hygiene...
All Hotels and resorts use water everywhere like bathing, laundry, cooking, drinking, cooling, swimming pools, fire water etc. Main concern of providing and storing water is to keep them pure free from contamination and prevent the growth of algae and micro-organisms.
Most power plants, be in Nuclear or Gas or Coal based, come up close to rivers, canals and the sea as they need large amounts of cooling-water. All water, especially sea water, contains fish, sea organisms, pathogens and algae. This leading to micro and macro fouling which adversely affects the efficiency of the power plant.
Ballast water tanks on board ships are filled with water from one sea and discharged in another sea can cause marine ecological imbalance by introducing foreign species of aquatic life. The discharge of water from ballast tanks has been responsible for the introduction of species that cause environmental and economic damage.
Offshore and on shore facilities using seawater in their Firewater System face the problem of marine growth like algae, mussels etc. This growth if unchecked will lead to chocking of the pipeline and starve the jockey pumps.
Water contains various microorganisms, bacteria, protozoan, that contribute to a bio-film formation on the membrane surface. Killing bacteria and microorganism using sodium hypochlorite before it enters the membrane prevents bio-fouling on the membrane and increase its life. In membrane desalination and separation processes, bio-fouling is a very critical operating issue.
Sea water systems on many offshore platforms are treated with small amounts of chlorine to prevent marine growth inside piping and equipment. Marine growth and fouling in Floating production Storage and Offloading vessels (FPSO) reduces heat transfer in condenser and heat exchanger and restricting cooling water flow in pipes. This reduces the overall efficiency and safety of the plant. In severe cases the plant may need to be shut down. Fouling also increases corrosion by restricting oxygen diffusion and...
