Moerk Water design and build health sector specific water treatment solutions that can treat any water source into water that is compliant with the latest regulations.

IS your WATER SUPPLY AS/NZ4187 compliant?

Moerk Water has been designing water treatment solutions for the healthcare industry for more than a decade. During this time there has been a raft of changes in the healthcare water treatment space with many facilities no longer having compliant water for supply to their sterilisation departments. In Australia, water for central sterilisation supply departments (CSSD) must now comply with AS/NZ4187 – washer disinfectors with the parameters listed in Table 7.2 and steam sterilisers with the parameters listed in Table 7.4. Moerk Water have extensive experience designing CSSD RO plants for healthcare facilities to ensure they comply with the new regulations.

While many water treatment companies are able to provide the required physico-chemical characteristics of the water, they often struggle to meet the microbiological demands. Moerk Water’s experience and access to highly experienced healthcare consultants with experience working in Central Sterile Supply Departments gives them a richer understanding of how best to design and construct water treatment systems for healthcare facilities to ensure the water supply complies with AS/NZ4187.

In addition to metropolitan health facilities, Moerk Water has extensive experience providing clean water to remote health clinics. Moerk Water have provided clean water for maternal health clinics, eye hospitals and rural hospitals. By combining their experience in healthcare locations in the Asia-Pacific, Moerk Water is able to design compliant water treatment systems regardless of location

Moerk’s water treatment technology can convert a wide range of water types into compliant water for the healthcare sector .

Sea Water

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.

Brackish Water

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.

Bore Water

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.

Fresh Water

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.

Ground Water

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.

Surface Water

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.

Dam Water

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.

Creek Water

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.

River Water

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

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.

Saline Ground Water

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.

Preferred Technology for the Healthcare Sector

Our treatment plants are individually designed to meet the specific requirements to create a supply of water that is safe for use in the healthcare sector.
