Clarification in Drinking Water Treatment Plant

The project consists of a Water Treatment Plant revamping in Riyadh, Kingdom of Saudi Arabia, originally built in the 1970s. The ancient clarifiers used an obsolete model of drive unit with a V-belt system for speed change. The mixers in the existing tanks were in very bad condition. Rust covered all the wetted parts.

In 2014, two PRO-DO-MIX’s engineers visited the plant to evaluate the situation and take all measurements, in order to redesign all mixers parts, aiming at the plant revamping.

Our technical team carried out an accurate analysis in order to offer the best solution. We wanted our design to be customized, that is tailored on our customer’s needs, and sustainable in the long term.

PRO-DO-MIX proposed 4 special vertical mixers model GPX.A5351.Q.285 / PSXBY, with heavy-duty bevel gearbox, frequency converter (VSD) to run 5 to 10 rpm and 15 kW installed motor. The impeller has diameter 3.400 mm. All wetted parts are made of SS 304L.

PRO-DO-MIX and our local distributor, GHADEER TECHNOLOGY FOR TRADING EST., have taken over the engineering, the manufacturing as well as the turnkey installation of the new equipment.
