Using less energy to clean and cool water

Waterix’ aerators, mixers, and coolers offer advanced, environmentally friendly water treatment with a low energy footprint. Although only a young business, the company’s R&D team has already been granted more than 30 patents.

Waterix pays particular attention to overall lifecycle costs and eco-efficiency in the design of its products. As a result, they offer lower energy consumption than competing technologies, easy installation and servicing, and excellent controllability.

This has made them popular in both industrial and municipal treatment plants, while smaller models are ideal for oxygenating lakes, ponds, fish and crab basins, and even ponds on golf courses.

Programmability

Waterix’ AIRIT aerators combine the high operating efficiency and controllability of bottom aerators with the reliability and low capital cost of surface aerators.

The use of large intake pipes, which can be up to six meters deep, means that water can circulate easily. Once on the surface, water is thrown out horizontally in carefully controlled droplet and spray patterns and aerated.

To ensure optimum energy usage, a programmable AC drive is used to control rotational speed. Oxygen sensors measure the oxygen level in the water and pass this data on to the drive, which automatically regulates aerating capacity as needed.

Waterix’ CORONA BOREALIS aerator improves water quality and provides an attractive water feature for golf courses.

The in-built programmability of the system also enables customers to set up things such as automatic propeller cleaning cycles and tailored aerating/mixing sequences.

The light weight of Waterix aerators is also a plus. Smaller cranes are needed to install units at wastewater treatment plants, while units used in natural water areas can be installed and moved manually.

Cooling things down

By modifying droplet size and using larger and higher spray patterns, an aerator can make a highly efficient and cost-effective cooler – and Waterix COOLIT coolers are ideal for cooling hot process water and acting as condensers for cooling basin water.

Two small COOLIT 8000 units weighing about 80 kilos, for example, can replace an entire cooling tower of the type widely used in the forest industry weighing almost a tonne.

Thanks to their large intake pipes, Waterix coolers are virtually always blockage-free, something that is particularly appreciated on golf courses, and a slightly modified version of the COOLIT 8000 has been specifically designed for aerating and cooling golf course ponds.

AIRIT aerators are so efficient at mixing wastewater that other mixing methods are rarely needed.
