Phosphate removal

With a chemistry similar to the antacids used in our human digestive systems, Calix can safely and cost-effectively remove phosphate from municipal and industrial wastewater.

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.

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.

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.
Australian manufactured.

Calix ACTI-Mag may hold the key to maintaining the balance within the phosphorous cycle, enabling capture within waste water treatment solids which can be recycled directly back into the food chain. This webinar explores ways that you can reduce the phosphate within wastewater effluent while improving the quality of sludge.

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.

The Calix difference

People, unique technology, partners, and track record

Leading edge technology

Calix core technology makes high surface area materials (with a honeycomb-like structure), giving you a price and a reactivity advantage.

Our materials are proving to have similar properties to highly active nano-materials, without the health/safety concerns and high cost, but with all the benefits.

Faster reactivity = less costs

Manufactured in Australia

Fully integrated supply chain – 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.

Chemical dosing systems

Calix leverages a culture of innovation to provide fully customised services such as design expertise, engineering know-how, detail engineering, installation, piping and commissioning services to provide turnkey systems for chemical dosing of Magnesium Hydroxide Liquid (MHL).

Our engineered and cost-effective solutions are tailored to meet your specific needs and budget. Quick to install – our modular dosing units can be delivered on site by truck and are fast to set up and connect.
