Sewer repairs generally involve shutting the line down and applying a structural cement or plastic, or a non-structural coating such as epoxy lining, or completely replacing the infrastructure if it is deteriorated beyond structural integrity.
All these methods are expensive, time-consuming, interrupt the sewer service and involve man-entry.

Presence of hydrogen sulphide gas in sewers.

The presence of Hydrogen Sulphide gas (H2S) gas can result in hazardous work environments, odour complaints and accelerated corrosion of sewer assets, pump station wells, discharge manholes and treatment plants.

There is direct co-relation between the asset wall pH and the ensuing asset wall corrosion in mm/year. The whole-of-life cost of corroded sewer assets has been estimated at many thousands of dollars per km resulting from H2S gas.

KEY STEPS IN THE CORROSION OF CONCRETE SEWER ASSETS

  1. Generation of H2S in sewer lines fills up the manhole.
  2. Oxidisation of H2S to H2SO4 by humidity / condenstion, reducing pH.
  3. Sulphide oxidising bacteria (SOB) form colonies as pH drops.
  4. Convert H2S to H2SO4 (sulphuric acid) = corrosion of asset.

DON’T WAIT UNTIL IT’S TOO LATE
CHANGE REACTIVE MAINTENANCE INTO PREVENTATIVE MAINTENANCE

Calix understands the importance of providing a complete repair and protection package for the entire sewer network. Calix innovates in chemicals to offer the right combination of solutions depending on the condition of the asset, your budget constraints and each site’s specific requirements. With a combination of CAC and PROTECTA-Mag, we can offer you the most suitable and cost-effective solution.

INSPECT

We can inspect manholes, wet wells and inlet works to assess their level of corrosion and to ensure long-term performance.

REPORT

Our detailed inspection reports are easy to read, include GPS coordinates and photos, and highlight required works to accurately price ongoing protection and repair works to protect your assets.

PREVENTION STRATEGY

Calix innovates in chemicals to offer the right combination of solutions for your sewer network, depending on the condition of the asset and each site’s specific requirements.

REPAIR

Calix uses Calcium Aluminate Cement (CAC) to repair failed concrete sewer assets. The scope of works includes re-grouting and profiling of significantly corroded manholes and pumping stations with CAC.

PROTECT

Calix’s technology PROTECTA-Mag rises the surface pH, inhibiting the formation of acid producing bacteria, thus protecting the integrity of the walls of the asset against corrosion. The combination of CAC and PROTECTA-Mag can dramatically extend the lifespan of sewer assets. Extensive testing on several assets coated with PROTECTA-Mag clearly show pH levels remained high long after application and no corrosion was occurring.

ASSET LIFE EXTENSION

Proper application by trained personnel is the key to success. Calix has become a recognised expert in the area of corrosion protection. With access to the most advanced technologies, skills and equipment, we offer the right and most cost
effective corrosion prevention solution to help extend the life of your assets.

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.

HASSLE FREE DELIVERY, LOCAL SERVICE AND SUPPORT YOU CAN COUNT ON, WHEREVER YOU ARE LOCATED.

Calix has its own direct delivery, service and support capabilities and also has an established a network of local distributors and partners that can provide the best solution for your specific needs and ensure you receive excellent customer service and support.
