Energy Vault Storage Towers

Energy storage capacity is forecasted to grow by 6000% globally from 2016 to 2030. The main reason being the unpredictability of renewable energy and the need to store excess energy when available and release the energy when needed to stabilize the grid.

The current Energy Storage market is dominated (95%) by Pumped Storage schemes which are limited due to topology constraints, water availability and costs. Electro-chemical battery technology for utility scale applications is still in its infancy and costs are high.

The disrupting Energy Vault storage technology was developed by a Swiss company, Energy Vault Société Anonyme. This solution emulates Pumped Storage technology by lifting and stacking 35-tonne concrete blocks to store energy and the lowering the same blocks to generate energy.

Energy Vault storage towers can be built anywhere and has the added environmental benefit that 32,7 tonnes of recycled building rubble and waste materials like mine dumps and ash dumps can be used per block, thereby converting environmental waste into energy storage assets.

We are partnering locally with iX engineers with this initiative.

Effective Bio-Aire Aerators

Aeration, the process of increasing oxygen levels in contaminated water, is a critical process of water treatment. Traditional aerators have moving parts and consumes high levels of energy.

The Bio-Aire is a disruptive and highly efficient aerator that consumes in the order of 20% the energy of conventional aerators. It has no moving parts, does not clog and can be easily deployed to contaminated ponds to reduce high levels of ammonia, phosphates, suspended solids and chemical oxygen demand.

Bio-Aire increases the capacity of Aerobic Modules of Water Water Treatment Works (WWTW) at a fraction of the cost of expanding the works.

Sizana is working in partnership with Khubeka Construction who invented the highly efficient Bio Aire aerators

Hybrid Activated Sludge Systems

Smart Hybrid Activated Sludge units represent a unique and disruptive technology for rapid and simple upgrading of existing waste water treatment works (WWTW).

It enables existing WWTW plants to treat double the volume and achieve tighter standards for ammonia and nitrate removal.

Hydrolysis in the Smart units enable increased performance of aeration tanks and better sludge settlement.

Smart systems can be used to increase the capacity of WWTW at a fraction of the cost.

Smart systems are installed offline, can be rapidly deployed, existing assets can be retained and are simple to commission.

Sizana works in partnership with Headstream Water in the provision of Smart Hybrid Activated Sludge systems.

Smart Water Metering and Billing

Smart water metering entails the data collection and analysis of hourly water readings of consumers and district metered areas to empower stakeholders with knowledge regarding their consumption and billing in near real time through the advanced Internet of Things (IOT) technologies.

Sizana co-founded a boutique 'Smart Water Monitoring' software solution that enables water balances to be determined in real-time, leak detection and alerting to be instant and billing to be automated.

Sizana is partnering with Water Shedding (Pty) Ltd to roll out smart water metering solutions.

Infrastructure Financing

Sizana is partnering with the Gaia Group who specialize in the financing of bankable infrastructure.

The Gaia Group facilitates the investment of developer and long term capital into infrastructure projects.

The specialisation areas for investment is in renewable energy, energy storage, transport, water and sanitation.

Leak Proof Toilet Cisterns

Leaking toilets are a big source of water losses. It is particularly problematic in areas where consumers do not pay for water. Poor quality cisterns leak soon after installation and non-paying consumers either take long to effect the repairs or never do it at all. This is a major problem for water supply authorities like municipalities who invest time and money to deliver the water but are not refunded for it by consumers.

We have developed a leak proof cistern by replacing the leak prone outlet valve which has a rubber seal at the bottom of the cistern with a dump bucket mechanism. We also re-engineered leak prone inlet valve into a robust solution suitable for low and high inlet pressures. The final solution is a slick cost effective robust product with only two moving parts (bucket connected to the handle) and inlet valve.

Sizana is partnering with Zambezi Sanitation (Pty) Ltd to roll out the Zambezi Eye cisterns.
