Lecta starts up biological water purification plant at Zaragoza mill in Spain

Saturday, Mar 28, 2015

Lecta has completed a new phase in its investment plan at Zaragoza pulp and paper mill in northern Spain. This phase, totalling some 23 million Euro, is focused on reducing the mills environmental impact, as the company said in the press release received by Lesprom Network.

Following the installation of two new electrostatic precipitators in the mill's recovery boilers, resulting in a 74% reduction in solid particle emissions, Lecta has started up a biological water purification plant with excellent results. In the first few months, there has already been a drastic reduction in effluent load, with values far below the legal limits. Chemical Oxygen Demand (COD) values were cut nearly in half, Total Suspended Solids (TSS) have decreased by 36% and in the case of Biochemical Oxygen Demand (BOD5), the decrease was even more pronounced — 72% compared to the average observed in 2013.

Zaragoza is Lecta's only integrated mill, manufacturing both pulp and paper with a total production capacity of 500,000 tons of pulp, coated paper, uncoated paper and base paper for specialty products.
