Industrial Water Treatment
Industrial water users can consume large amounts of water and create large volumes of difficult to treat wastewater during manufacturing and processing. Water used in these industries can have a wide range of quality requirements for use/reuse as process water and safe & compliant discharge to the environment.
Traditional water treatment methods such as reverse osmosis (RO) can generate large volumes of difficult to manage brine, creating a waste disposal issue in industrial areas where space constraints can limit the use of evaporation ponds. In many instances companies are moving towards zero liquid discharge (ZLD) due to their sustainability policies or regulations placed on the site by the Government.
Clean TeQ Water provides innovative solutions for treating industrial process and wastewater for reuse, or safe and compliant discharge to the environment. By providing customised flowsheets, we achieve the client’s specific goals, and can provide a solution which achieves higher water recovery and a range of other benefits. We provide tailored turn-key water treatment plants to customers around the world.
Targeted Contaminant Removal
Selective removal of contaminants is a key focus of our technologies, able to remove hardness, metal contaminants, nitrate, ammonia, and a range of other pollutants with high water recovery and minimum waste production. The selective removal can avoid creating concentrated saline brines, and in some cases can create pure reusable product streams after the impurities have been removed.
Robust Water Treatment
Industrial wastewater can have high concentrations of dissolved solids such as calcium, magnesium, sodium, chloride, and metal impurities, which can make it difficult to treat. Clean TeQ Water’s technologies are specifically designed to be resistant to scaling and fouling, which is commonly experienced by conventional water treatment processes without adequate pre-treatment.
Zero Liquid Discharge
Clean TeQ Water’s technologies and flowsheets provide affordable ZLD solutions. When removing contaminants such as calcium and sulphate, our CIF® (continuous ionic filtration) technology can produce a gypsum based waste which can easily be turned into solids.
Our HIROX® (high recovery reverse osmosis) technology typically achieves >95% water recovery, generating a much smaller waste volume than conventional RO. The smaller brine volume saves cost when using evaporation to achieve ZLD.
Our low energy evaporation technology, EVAPX™, has higher resistance to scaling than conventional technologies since evaporation occurs away from the heat source inside the humification chamber. The system is also much easier to operate and clean since flat plate heat exchangers are used and there are no complex internal geometries in the system. The system can be operated using waste heat if available to drastically reduce the power requirements and operational costs.
Ammonia and Nitrate Removal
Our BIOCLENS™ and BIONEX™ ammonia and nitrate removal technologies are able to meet very low target concentrations when required (< 1ppm). They can treat saline water and water with high initial ammonia/nitrate concentrations (> 1,000 ppm), which can pose an issue for conventional technologies. Very low waste production and low costs are key features of our ammonia and nitrate removal technologies, which typically convert the ammonia and nitrate to harmless nitrogen gas.
