Municipal – Water Treatment
Water Treatment Plants
Water Treatment Plants are built to treat ground water and water flowing from a source such as a river or a lake. The purpose of the water treatment process is to remove all contaminants within the water supply in order to produce either Potable Water for public consumption or water suitable for industrial or commercial use.
With experience spanning over 35 years’, Cantwell Electrical Engineering is a market leader in the design, build, installation & maintenance of Water Treatment Plants nationwide. We are regularly involved in large scale municipal authority projects and consider the quality of our service as a core element in our approach.
Cantwell Electrical Engineering offers Chemical Dosing solutions as part of our comprehensive water treatment products and services.
UV (Ultra Violet) Treatment destroys all impurities found in your water supply; however the effectiveness of this treatment is reduced after prolonged storage of the water. Chemical Dosing is highly efficient in killing the bacteria that may be introduced into water after it has been stored in a water tank. Sodium Hypochlorite is typically added to the water to assist with chemical dosing, while pH Correction and the addition of Hydrofluosilicic acid, are other common chemical dosing practices.
Water, in its natural cycle, flows through areas and grounds of different nature before flowing into rivers and lakes, which unfortunately are sometimes polluted by industrial, agricultural or domestic waste. If such pollution occurs, bacteria can enter the water supply and it becomes unsafe for consumption, food preparation, brushing teeth, etc. In this case, UV (Ultra Violet) Water Treatment is one of the most effective treatments available.
The working principle of this comprehensive treatment is very simple and involves no chemicals. Ultraviolet light is lethal to all bacteria and micro-organisms and once the water is passed through this UV chamber, the UV light destroys all impurities present.
At Cantwell Electrical Engineering, we can provide UV Treatment solutions tailored to suit the requirements of a single property supply, or on a greater scale, to treat the water being produced by Local Authorities at a Municipal Water Treatment Plant.
Reverse Osmosis is the ultimate in water filtration & purification. Our RO systems are advanced compact purification units. Installation is very easy and in a domestic property, it is generally carried out in the space under the kitchen/utility sink. Using Osmotic Membranes, combined with some or all of the following; Filtration/Chlorine Removal/UV Sterilisation, our systems guarantee a supply of pure water, free from odour, chemicals and bacteriological pollutants. Water is forced at high pressure through these micro-fibre membranes and filters and all possible impurities are removed and the purified water is discharged via the RO tap at the sink.
The water produced is optimal for drinking, preparation of infant formula & foods, cooking, ice, coffee machines, washing of fruit & vegetables and so on.
Instrumentation is required to measure the water treatment process. Cantwell Electrical Engineering offers a comprehensive range of water treatment solutions that assist in measuring the water flow, pressure in the water line and chlorine and fluoride levels.
Cantwell Electrical Engineering’s control mechanisms are implemented to measure and monitor all activities within our waste water treatment plants. These control systems facilitate the effective removal of contaminants from sewage and ensure that the subsequent water waste is compliant with all health and safety guidelines and standards.
Our control systems also carefully monitor the energy consumption of a plant. Based on the findings, we can carry out repairs and adjust variable speed drives to help achieve optimal performance.
