Carocell technology also boasts Zero Liquid Discharge technology, one of the best water purification systems which converts waste brine into drinking water and valuable fractionalized salts and minerals.
Benefits
Carocell panels run as a continuous operation, feed water travels slowly down individual panels, during every pass approximately 30–50% of the flow is extracted as distilled water increasing the salt concentration of the waste water at every pass. The heated waste water is then pumped to the next series of panels where the same process is repeated. The wastewater is treated depending on its TDS as many times as required to bring the salt concentration up to a density of around 1.2 to 1.25 which then goes to the salt production stage for NaCl crystallization. In the case of sea water the waste liquid after NaCl production will be approximately 30% MgCl2 which can be sold as a liquid or crystallized in a subsequent panel. Other salts and metals drop out in earlier stages and may also be harvested if they are of commercial value.
Carocell’s increased efficiency (65% with peak efficiencies above 80%) over other solar distillation products (30 – 40%) is a combination of the proprietary materials used to dramatically increase the temperature of the feed water on the solar collector which enhances the evaporation/ condensation processes inside the panel. And the sophisticated geometrical design allows for easy maintenance, optimum performance and a self-controlling natural convection loop enabling widely superior energy recovery.
