WHAT IS UV STERILISATION?
UV Sterilisation is the go-to solution when you are treating biologically contaminated surface water. Reverse osmosis will remove all microbiological content from the water and concentrate it into the effluent stream and will also remove the salt. On the other hand, UV sterilisation physically sterilises the water using ultraviolet light without removing any of the dissolved components. Water sources can easily become contaminated with a range of pathogens. It is crucial to remove the microbiological content from water, particularly if it is intended to be used for irrigation, spraying, human consumption, or watering livestock.
- Remove most suspended solids and sterilize all biological contaminants
- Produce potable water from a contaminated source (depending on the feedwater quality)
- Low energy requirement
- Low capital cost
- Easy to scale
HOW DOES IT WORK?
UV sterilisation is a two-stage physical filtration/disinfection process. The first stage removes larger suspended solids using a media filter (that backwashes automatically). Once the suspended solids have been reduced to a specific level, then the water is sterilised by a powerful UV lamp. It is important to note that this system will not remove smaller dissolved solids like salt and that the water will need to be used soon after sterilisation as the disinfection is not persistent.
WHEN SHOULD IT BE USED?
This is the ideal solution for treating contaminated surface water, provided there isn’t also a salt issue. UV will significantly reduce the contaminant load. The advantage of this type of solution over other methods is the lower CAPEX and scalability. The feed pressure in the pipeline can be sufficient to move the water through the system and back-flush the media filter, further saving on capital costs.
UV Sterilisation Water Treatment PROJECTS
UV STERILISATION APPLICATIONS
Our treatment plants are individually designed to meet the specific requirements to create a supply of water that is safe for drinking or use in commercial and industrial situations.
Moerk Water leads the industry in delivering solar-powered reverse osmosis solutions to the Australian agriculture industry. Australian farmers face increasing salt levels in their water sources due to drought, vegetation loss and unreliable weather patterns, all of which cause water tables to rise. Our expert engineers have the experience and expertise to understand your farm’s unique conditions and work with you to develop the right solution.
Moerk Water units are constructed from quality materials and are built to last ensuring that resorts never run out of clean water. We have extensive experience operating in remote locations. Our units not only provide a decentralised water supply solution, they are powered by solar and wind energy, which removes the need to rely on diesel generators. Our desalinator technology allows coastal resorts can make use of abundant ocean water as a water supply option. They also allow eco-resorts to operate chemical-free, thus minimising their environmental impact.
Food and Beverage processors can face numerous water challenges including supply quality, trade waste volumes, treatment failures and contamination risks in treatment and distribution systems. Our water treat technology has been designed to ensure a secure and reliable water treatment solution.
Government of all levels not only needs projects to come in on time and on budget, but to meet increasing community expectations for sustainability. We have a wide range of council and government experience when it comes to design and construction of water treatment technology. Procurement staff, project and executive managers can rest easy with Moerk Water’s commitment to being upfront about treatment system costs and ensuring budgets are not exceeded.
Reducing the volume of trade waste and the cost of scheme water use, as well as improving on-site water metrics are among the significant challenges faced by industry. Industry also faces the needs to ensure that water treatment systems can be integrated into existing control systems, are easily operated and meet safety standards. This is where Moerk Water’s significant experience and expertise in design and construction plant and systems comes into play.
We provide desalination equipment and consulting services in countries including Tanzania, Kenya, Somalia, Ethiopia, Myanmar, Solomon Islands, Papua New Guinea, Vanuatu and Kiribati. At Moerk Water we’re proud that our treatment plants have helped communities achieve increased health, socio-economic and environmental outcomes. We work with local communities to empower them to take ownership of the systems we build. This allows often remote communities to maintain and operate their new water treatment technology by providing them with technical training and education. By training local people to maintain and operate the technology, employment opportunities are created in addition to the other health, economic and social benefits that result from our water treatment plants.
Australia’s often harsh environment and extreme climate requires robust water treatment solutions. Out water treatment systems are built to withstand the most rugged conditions Australia has to offer. Our technology provides our clients with reliable water supply, a source of clean water to improve community health, decentralised systems that allow water production where it is needed, solar-powered water treatment systems that remove reliance on diesel fuel, and training programs to build local expertise in water treatment and solar power. Our holistic solutions help our clients reach their organisational objectives and key KPIs, create local jobs, promote local business development, and work to strengthen and equip local communities.
WATER SOURCES WE TREAT WITH UV STERILISATION
Moerk’s water treatment technology can convert a wide range of water types into safe drinking water that meets World Health Organisation water quality standards.
The best way to treat contaminated groundwater is to pump it through one of our specially designed groundwater treatment systems that can clean ground and surface water. The cleaned water can then be put back into the ground or stored for immediate use, which allows stakeholders to get the most out of their water assets.
Desalination treatment plants are one of our most sought-after systems. Our membrane systems are designed to remove salt and almost all other water contaminants through the process of reverse osmosis. It’s a tried and tested method that we have adapted to be transportable to even the remotest locations as well as adaptable to any scale and completely self sustaining.
Just because water is fresh, does not mean it is fit for purpose. Moerk’s specialist team can provide water consultancy services, then use the results to advise on the best treatment solution to ensure your fresh water supply is free of contaminants, including bacteria, parasites and viruses, as well as particles. The result is water that is not only safe for human consumption but for use in your specific situation.
Surface water, including rivers, dams and stream, is extremely vulnerable to contamination by pollutants including chemicals, bacteria, parasites and viruses. Like ground water, it can be easily treated and made safe for use by our specially designed treatment systems.
Bore water can contain high levels of minerals including sodium, calcium, magnesium, potassium, chloride, bicarbonate, and iron. This not only makes it unsafe for human and animal consumption, but also for irrigation. Moerk’s water treatment technology can turn bore water into a safe, useful asset.
Dam water, like other surface water sources, is vulnerable to contamination from ground runoff, pollution, contamination by human and animal waste as well as algal blooms. Our expert engineers can design a dam water treatment system that will enable you to use dam water safely for agriculture and stock.
Brackish water may have lower salt levels that sea water but is still unsuitable for use in agriculture or for stock to drink. Moerk’s desalination technology, encompassing reverse osmosis, provides a simple to use, reliable solution to brackish water. Our team can design and construct a system that will convert brackish water to a useful resource.
Creek water, like dam and river water, is prone to pollution from runoff, human and animal waste, chemicals, bacteria, parasites and viruses. We can design and build a treatment system to suit your specific needs and convert creek water into a clean, safe water source.
Rivers are an extremely valuable source of water for agricultural use. But they are also easily contaminated by debris, runoff, pollution, bacteria and parasites, as well as human and animal waste. We can help you to make this most of this resource through water treatment technology that will remove contaminants.
Saline water is easily treatable using one of our desalination treatment systems. Our membrane systems easily remove salt using reverse osmosis. Our engineers can help you to choose the right saline water treatment system for your needs. They are easy to transport and can be adapted to any scale.
Ground water can become increasingly salty as rainwater deposits of small amounts of salt build up over time, until it can no longer be safely used for crop irrigation or watering animals. The solution can be found in Moerk’s range of desalination treatment systems. Our specialist team members can guide you through the process of choosing the right system to remove saline from your ground water.
OTHER PLANTS & SYSTEMS
Clarification Filtration is a chemical/physical method to reduce the dirt load in the water. Fine particles below a certain size will pass through standard filters. Following clarification filtration, depending on the water quality required, the water can be further purified to reduce the salt load or remove any other contaminants of concern.
Moerk Water’s Iron Removal Systems remove iron from any water source, eliminating concerns about iron bacteria contamination, corrosion, and scaling. Our iron removal systems utilise aeration mechanisms and filters with an automated backwash to reliably removing iron from the water while keeping the systems hands-free and operating costs as low as possible.
Typically when we think of reverse osmosis we imagine large facilities that underpin a city’s water supply or small under sink units. However, in our context, we have adapted these membrane systems to be both transportable and optimised for whatever scale various agricultural and commercial concerns require.
Moerk Water specialises in designing and building custom desalination plants and systems to treat various saline water sources to achieve water that is ready for commercial application and/or safe drinking water.
