Ultrafiltration-basic

A bottled water manufacturer in New Zealand needed to be sure that their artesian bore water would be delivered to their customers consistently at the right quality. The company engaged MAK Water to deliver two Ultrafiltration (UF-B) plants. The membrane filtration process acts a physical barrier to viruses and pathogens, and removes any suspended solids that may be present in the water. This process was selected over conventional sand filtration or reverse osmosis as it purified the water without altering the chemical composition and enabled the bottled water to remain a consistent quality despite some variation in the raw water supply conditions.

One of the largest producers of Oysters on the south coast of NSW was using a large volume of potable water for the washing and shucking of their Oysters. This water made just a single pass over the Oysters before it made its way to sewer. To reduce water consumption and minimise impact on the environment, the customer decided they wanted to recycle this water back to the front of their process. To achieve this, they needed a system that could remove sediment from the wastewater and provide protection from bacterial build up.
