ACTI-Mag for phosphate removal

ACTI-Mag, a very high surface area magnesium hydroxide liquid, targets phosphate while improving pH and organics removal within the wastewater treatment plant.

WHY IS PHOSPHATE AN ISSUE?

Phosphorus – usually in the form of phosphates – comes from sources such as human and animal waste, detergents and food residue. It has to be treated and reduced from the wastewater in order to meet environmental standards before it is discharged into a local water body, or land irrigation.

There are two methods of removing phosphorus from wastewater: biological removal and chemical removal. Establishing and maintaining biological conditions for effective and continuous biological phosphorus removal can be quite challenging.

ACTI-Mag boosts this biological phosphate removal while at the same time capturing the excess phosphate within the sludge, which is beneficial for composting of solid waste.

Key Benefits

A much simpler method of removing phosphorus is to dose ACTI-Mag into the wastewater.

Significant reduction in phosphate levels at discharge.
Improvement in effluent BOD and COD.
Stabilised pH throughout the waste water treatment system.
Elimination of FOG build up in the anaerobic ponds.

HOW DOES ACTI-Mag WORK?

ACTI-Mag has demonstrated rapid capture of most phosphate as a solid within the sludge, reducing effluent nutrients with potential to form phosphate-based struvite scale. The highly porous ACTI-Mag particle structure causes phosphate and ammonia to crystallise within the particle. The high pH inter-particle boundary layer is used to rapidly capture these nutrients in the sludge which, when used as compost or fertiliser, improves root growth and bloom of flowering or fruiting plants.

WHY CHOOSE CALIX

FROM MINE TO CUSTOMER

Calix is able to offer better service, reliability and performance to its customers because it controls the entire production process from mining of raw materials, processing and production.

Calix owns and operates a mine in South Australia as well as production, testing facilities and manufacturing plants. The ability to hydrate our high surface area MgO in our patented, close-to customer facilities creates multiple benefits for our customers and local communities.

Our AS/NZS ISO 9001 certified quality system and safety, health and environmental management system are vital elements of our engineering and quality services.

FASTER REACTIVITY = COST SAVINGS

Calix’s solutions are manufactured using Calix Technology, which involves grinding minerals to particles around one thousandth of a millimetre in size, and then “flash” heating them in a very short time at up to 1.000 degrees Celsius. As trapped gases in the mineral “bubble out” of the particles, we snap freeze them in a very high energy state, leaving a very porous, honey-comb-like structure.

New materials produced by Calix Technology are proving to have similar properties to highly active nano-materials, without the safety concerns and high cost, but with all the benefits. This means it has the high reactivity of nano-material, without the potential health and handling issues.
