EMI sp. z.o.o.
About
Cempuro, operated by EMI sp. z o.o. from Poland, manufactures ceramic ultrafiltration systems that recover potable water from filter backwash streams at drinking water treatment plants. The company's core technology uses silicon carbide ceramic membranes sintered at over 2000 degrees Celsius, operating under vacuum-driven ultrafiltration at 0.1 micrometers filtration precision. Unlike polymer membranes, SiC membranes can be restored to factory performance even after years of operation through chemical cleaning, and they deliver the highest water permeability of any membrane type according to Cempuro's testing data. The standard Cempuro Recovery Device is a plug-and-play unit available in flow rates from 1 to 10 cubic meters per hour, requiring only three hydraulic connections and a power supply for installation in under a week. For sites needing temporary or emergency capacity, the Cempuro Container provides a mobile ultrafiltration unit for pilot testing and crisis water supply. All systems carry PZH certification for contact with drinking water and achieve turbidity below 0.1 NTU while removing over 99 percent of bacteria including E. coli. With more than 250 installations across 70 countries, Cempuro enables treatment plants to recover up to 99 percent of backwash water as drinkable quality, reducing waste discharge volumes by an order of magnitude. The company also offers a service purchase model where the device remains manufacturer property and users pay only for recovered water volume, converting capital expenditure into tax-deductible operating costs.
