Mantec Technology Plays Part in Massive Ozone Plant for Wastewater Treatment
In a recent six-figure deal, Mantec Technical Ceramics/UK has shipped specialist ceramic diffuser tubes and installation ancillaries that are currently being incorporated into one of the largest public sector ozone plants to be built in the Middle East in more than 10 years. The contract was placed with Mantec by Milan-based De Nora/IT, a global provider in sustainable water treatment solutions, and the plant in question is the Tubli Sewage Treatment Plant Phase 4 expansion in Manama, Bahrain, one of the largest wastewater treatment plants in the country.
The new ozone generators in Manama will accommodate the increased flow of wastewater caused by rapid population growth in the area, doubling the average daily flow capacity of 200 000 m3 per day to 400 000m3 per day. Following initial discussions with De Nora, subsequent product redesigns and vendor prequalification, Mantec supplied a large number of 600-mm-long ceramic diffuser tubes and associated fittings. For this project, Mantec’s Pyrolith grade material was chosen. It is ideal for diffuser tubes, featuring an average pore diameter of 90 µm and porosity between 35 % and 45 %. This is a proprietary aluminosilicate material for which Mantec is renowned, and over the past 15 years or so it has supplied over 100 000 large ceramic diffuser tubes for wastewater treatment and ozone applications.
Clearly, all parts were required to be specified for compatibility with ozone. This meant that the caps and fixings were manufactured from 316 Ti stainless steel, a special grade of austenitic stainless steel that contains a small amount of titanium for improved corrosion resistance. Silicone gaskets were specified for compatibility. The contract was delivered three weeks ahead of schedule.
