Chlorination is one of the most prevalent methods of water disinfection. Chlorine can be applied in different processes to destroy target organisms and prevent the spread of diseases to make the drinking water fit for human consumption.
The complete line of De Nora gas feed disinfection technologies include Chlorination, De-Chlorination / Sulfonation, Ammoniation and Recarbonation equipment. With more than 50 years’ experience and many thousands of installations globally, our De Nora Capital Controls chlorination system sets the benchmark for the best quality chlorinators in the market. All the equipment manufactured are ISO 9001: 2000 certified. We have the highest presence in all municipal water treatment plants.
Electro-chlorination or also termed On-site hypochlorite generation system is the production of a dilute form of disinfectant compared to chlorine gas or concentrated commercial hypochlorite. As a result, handling, transportation and containment are easier and safer.
De Nora ClorTec® have a strong reputation as the leading global technology provider with a proven track record of more than 3000 global installations. The ClorTec® systems generate a 0.8% sodium hypochlorite disinfection solution, a chlorine equivalent, using three common consumables: salt, water and electricity. The patented split flow design allows for the lowest operating cost in the industry.
The Mengkubau Water Treatment Plant has been operational since year 2000. Under the upgrading project managed by the Ministry of Development through the Water Services of the Public Works Department in year 2015, about 40MLD of clean water has been supplied to 4,000 housing unit at the Kampong Panchor/Mengkubau National Housing Scheme in the Brunei Muara District.
The Electro-Chlorination system supplied and installed by Greendex in the Mengkubau Water Treatment Plant has demonstrated reliable and economic operation. Greendex also provides the customer with a tailored 2 years operation and maintenance regime to ensure optimum electro-chlorination plant performance.
The Bertam DAF II water treatment plant has been operational since 2014.
The water authority is among the first in accepting the new disinfection technology among the states of Malaysia and the first to install the largest electro-chlorination system to date.
The system has been operating for more than 3 years and have proven success in terms of savings in operation cost in addition to being a safe disinfection system with reduced hazards.
The benefits of the on-site sodium hypochlorite generation systems include:
Ultraviolet (UV) is chosen as the advance non-chemical disinfectant option for municipal water and wastewater treatment because it is a highly effective method of destroying microorganisms.
The effectiveness of germicidal UV in such an environment depends on a number of factors: the length of time a micro-organism is exposed to UV, power fluctuations of the UV source that impact the EM wavelength, the presence of particles that can protect the micro-organisms from UV, and a microorganism’s ability to withstand UV during its exposure.
Theory of UV Disinfection
DNA adsorbs UV energy between 250 and 265 nm
Chlorine Dioxide is a very effective disinfectant against cryptosporidium and has no reaction with ammonia.
Our system produce chlorine dioxide and consistently maintain a product yield greater than 95%, making it ideal for drinking water treatment.
Benefits:
With more than 45 years’ of dedication to solving some of the toughest problems and treating some of the most difficult pollutants such as hydrocarbons, surfactants and phenols, De Nora Ozone is one of the original pioneers of ozone treatment solutions for industrial applications.
Ozone can eliminate a wide variety of inorganic, organic and microbiological problems and taste and odor problems. The microbiological agents include bacteria, viruses, and protozoans. (such as Giardia and Cryptosporidium) In addition, the oxidizing properties can also reduce the concentration of iron, manganese, sulfur and reduce or eliminate taste and odor problems.
Ozone offers a range of advantages:
Because of its excellent disinfection and oxidation qualities, ozone is widely used for drinking water treatment. At municipal plants ozone can be added at several points throughout the treatment system, such as during pre-oxidation, intermediate oxidation or final disinfection. Usually, it is recommended to use ozone for pre-oxidation, before sand filters or with active carbon filters (GAC).
