Packaged Metering & Pumping Solutions (PMPS) has announced that it will be introducing an Italian OBL Polisol automatic polymer preparation plant to the South African market. Used in water and waste water treatment plants, the system’s wetting-in capabilities provide for better, higher quality yields of water.

Used to prepare and mature dry polymer beads or powder by dissolving it into water to form a uniform and consistent concentration of polymer solution, the system is predominantly utilised in water and waste water plants to aid in the aggregation of small suspended particles to form a floc for filtering or settling out.

While there are many polymer systems available in South Africa, the Polisol system comes with a number of distinctive advantages, according to David O’Neill, PMPS Technical Director. “The main differentiating factor between the Polisol system and others is the initial point at which the dry polymer is wetted. The device has to ensure that the polymer beads are constantly wetted, or it will form lumps and ‘snake eyes’, which both hinder the treatment process. OBL’s patented wetting-in device uses a vortex and venturi to keep this from occurring, ensuring a high-quality dilution,” he says.

The OBL Polisol range includes the AISI 304 Tank and Hopper as well as the PP Tank with AISI 304 Hopper. Standard units with either two or three compartments are able to provide from 450 to 10 000 litres/hour output per day of 0.5% polymer solutions.

Mimic control panels make the system easier to start up and control and forced dilution takes place by means of a dilution funnel with built-in venturi system. Plants can also be combined on demand to accommodate for both dry and liquid polymer and optional local pneumatic filling system.

With capital buy-in between R130 000 and R500 000 on the Polisol system, depending on the size and configuration of the system, PMPS is able to customise the system to suit the desired application. “We have the capability to provide a skid system including dosing pumps, flowmeters and valves, for example, to render the system fully functional as a standalone plant,” O’Neill says. “With its high-quality hardware, superior yields and customisable features, the Polisol system represents the means to a clearer, cleaner future for South Africa’s water supply.”
