A few weeks ago, published the following technical paper in the INDUSTRIA QUÍMICA magazine: SUSTAINABLE SOLUTION FOR SAVING WATER AND ENERGY THROUGH REUSE OF COOLING TOWER PURGE.

This work evaluates the performance gains, water and energy savings, operating cost reductions and CO2 emissions₂ reductions that have resulted from the use of a specifically designed phosphorus-free, biodegradable antiscalant and a cleaner that does not contain EDTA or phosphorus in its formulation in a real reverse osmosis plant that treats cooling tower blowdown water for reuse.

Prior to ADIQUIMICA’s intervention, the reverse osmosis plant was affected by severe biofilm fouling and the membranes had to be cleaned frequently, causing a drastic decrease in performance. In addition, the plant was operating at a lower conversion rate than designed, due to the high fouling power of the water and the use of a non-specific, broad-spectrum anti-fouling agent formulated with organic phosphorus.

Treatment with a specific, biodegradable antiscalant formulated from a synergistic blend of phosphorus-free active ingredients and the use of an environmentally friendly cleaner resulted in sustainable management of the reverse osmosis plant, with an increase in the use of reused water, savings in water consumption and a reduction in discharge. Energy savings were achieved and CO₂ emissions were reduced. Costs associated with membrane replacement, plant downtime for cleaning and chemical consumption were also reduced.
