If biomass such as bamboo is your chosen fuel to fire the DRAIG Energy Centre. Then as part of the process of burning bamboo, the bamboo passes through a drying station where we drive off water. In a 50MWe plant, the amount of water recovered from steam is approximately 100,000 Litres of pure water a day.
This water has been turned to steam, sterilised and then condensed. This clean water can be filtered and sent to a bottling plant.
The construction of a small bottling and treatment plant on site would allow for a seperate business model.
The water can be sold as still water or could be flavoured by the addition of a fruit concentrate. Once bottled into 500ml and 1L bottles, it is ready for distribution and sale.
COSTS
The cost of a small hand bottling complete water purification Reverse Osmosis with prefiltration, ultraviolet and ozonation system designed for Hand/Tap bottle filling - Producing approx 6,000 litre per day can be as little as $200,000
A Fully Automatic bottle blow moulding, water treatment plant and bottling and capping solution for 100,000 Litres a day would be approximately $2m - fully operational.
ozone treatment enhances the water quality of most drinking water in general. However, it is a key and essential treatment for the production of safe, high quality, good tasting, aesthetically pleasing and storage stable bottled water that the consumers have come to expect. The development and adaptation of ozone treatment in the 1970’s resolved the troublesome and sometimes embarrassing problems with disinfection and storage stability and set the water bottling industry onto its decades long rapid double digit growth pattern. By the year 2001, the annual sales of bottled water exceeded 5.5 billion gallons and surpassed $ 6 billion dollars in Africa. Ozone treatment is the most frequently used disinfection process in water bottling today. With the application of a single ozone treatment step, the water bottler can disinfect the water, the bottling equipment, the bottle, the air above the water and the sealed cap of the bottle, thereby provide a most effective barrier to microbiological contamination for the protection and benefit of the consumer. These are the reasons why most water bottlers rely on ozone treatment to provide a safe, good tasting, aesthetically pleasing and storage stable product. As the ozone treatment became a well accepted, routine part of the water bottling process, many of its other benefits beyond the disinfection have become taken for granted and nearly forgotten. Some water bottlers may not even realize today that the use of ozone also provides benefits, such as, improved taste, elimination of odour, and long 2 years storage stability. These benefits have improved their product substantially making it a good tasting and safe. These are the product quality features that the costumers have grown to expect and enjoy
A complete automated solution producing the blow moulded bottles, the ozone treatment plant, the automatic bottle filling and capping equipment capable of bottling 100,000 Litres of water a day would cost in the region of $2m. The treated water is Disinfected, the disinfection process treats the water against bacteria, viruses and parasites such as Giardia and Cryptosporidium. Ozone treatment is considered to be the most effective chemical disinfectant commonly available against all the above mentioned microorganisms. Chemical Oxidation: Ozone is a powerful oxidizing agent. It is very effective in water treatment against essentially all taste and odour causing organic materials and oxidizable inorganics like iron, manganese and sulphide ion. Again, these reactions have been studied in great detail and are reported on in the literature. The required ozone concentrations and reaction times are dependent on the type and concentration of the oxidizable pollutants present in the water and on the water quality. They should be determined experimentally in a treatability study. Decomposition: ozone is an unstable compound under room temperature and near room temperature conditions and decomposes rapidly to oxygen. The decomposition rate is influenced primarily by water temperature and pH. The half-life of ozone at 20oC and pH 7.0 is typically 24 minutes in potable water. In most cases there is ample time available for the ozone decomposition to take place before the bottled water is delivered to the consumer. Typically, 5-10 hrs should be sufficient. More specifically, the decomposition rate is dependant on pH, temperature and the type and concentration of inorganic salts present in the water.
Excess water can be Ozone treated and hand bottled to produce 6,000 Litres a day, for under $200,000
DRAIG have been providing combustion equipment and burner solutions across the World since 1951. The basic principles have remained the same whilst the designs have been modernised to deal with 21st Century fuel source requirements. Modern solutions to modern problems.
Growing Bamboo around each power station provides hundreds of new employment opportunities in each area.
