ECONOMICAL WATER TREATMENT SOLUTIONS TO MAKE EVERY LITRE COUNT

INNOVATIVE SOLUTIONS IN WATER TREATMENT CAN HELP TO MANAGE THE IMPACT OF WATER SCARCITY IN SOUTH AFRICA BY REDUCING CAPITAL COSTS AND WATER CONSUMPTION.

Water reuse and alternative water treatment systems have gained significant traction over the past decade as opportunities to optimise water usage. However, most of these options in the current market are known to be capital-intensive with payback periods of up to eight years.

The converse of capital-intensive operations are labour-intensive alternatives which pose their own challenges, especially when aiming to maintain a consistent water quality.

Sigura™ specialises in water treatment solutions that are easy to install, require minimal chemical handling and operator interference whilst keeping environmental care and safety at top of mine. The focus of the Sigura™ product range lies in disinfection and microbial control in many water applications such as drinking water, biofilm management in cooling towers and algae control in surface water bodies.

The majority of the Sigura™ product range is supplied in a convenient solid form which holds several advantages over similar products in liquid form. Solid chemical products generally require less storage space, does not require handling of heavy liquid-filled containers and spillages that do occur are much easier to contain and clean up.

Several of our product solutions can easily be applied in the residential and commercial construction industry to optimise water treatment and reduce the demand of fresh water.

Commercial swimming pools at property developments, hotels, lodges, and resorts are characterised by inconsistent bather loads and water treatment demands. During peak holiday season, these pools require more chlorine due to an increase in swimming pool use. Our automated systems are equipped with probes that constantly monitor free chlorine and pH levels in the pool water. Subsequently, only the necessary amounts of chlorine and acid needed to maintain these parameters at the required levels are added. Not only does this provide a constant free chlorine level in the water, but also prevents the overdose of chemicals which could have safety and cost implications. Our HTH Scientific® automated systems are supplied as fully assembled skids complete with dosing pumps, probes, and controlling unit to automatically maintain swimming pool parameters at required levels.

Our Applied Biochemists™ surface water products have a long history of success in the treatment of water in fountains and ponds at residential estates. Few things affect the aesthetic of an estate like a smelly water pond full of algae mats. The presence of aquatic wildlife and plants along with constant sunlight exposure create the perfect environment for algae to flourish. The efforts for removing algae from the water can in severe cases require the draining of the entire pond and employing physical labour to remove accumulated sludge at the bottom. The Sigura™ treatment process involves dosing any of our Cutrine® algaecides along with Bacti-Klear™, a blend of beneficial bacteria strains, to break down any organic matter in water ponds. An ongoing maintenance dosage controls algae growth, keeping the pond in mint condition.

One rarely pays attention to the cooling systems responsible for the operation of air conditioners and refrigeration systems in buildings – until they stop working. Small cooling towers are usually located in obscure places, out of direct sight, such as building rooftops or alleys making them a hassle to treat and maintain. However, when left untreated, a cooling tower can fall prey to scaling, corrosion and biofilm that can house dangerous bacteria like Legionella. Sigura™ offers a full portfolio of cooling tower products that can help maintain an environment conducive to minimal corrosion, scale, and biofilm formation. The Scientific™ C range for cooling towers includes a biocide, corrosion, and scale inhibitors as well as a bio dispersant – all in a convenient solid form. The scale and corrosion inhibitors are dosed automatically with the Scientific™ Ultra-S dosing unit and has been successfully installed and operated in cooling towers on manufacturing plants and shopping centre rooftops. Treating the water in the cooling tower leads to increased cycles of concentration and subsequently less water lost due to routine water blowdowns.

Through targeted product offerings, Sigura™ strives to minimise labour-intensive tasks and high capital investments associated with water treatment. A midway is possible with our solid chemical solutions and advanced automated dosing technology to provide consistent water quality, making every litre of freshwater count.
