Sludge Ash

Tannery effluent treatment plant sludge is a by-product of leather-making industry in which chrome compounds are the most common used materials. The aim of this work was to investigate the effects and feasibility in the use of tannery sludge ash as a partial or totally replacement of usual mineral filler such as CaCO3in manufacture of waterproofing membranes. The effects of sludge ash on the morphology and mechanical properties of membranes were investigated. Leaching tests were carried out in order to guarantee that the fulfillment of filler function was done in respect with environmental criteria. The results in terms of performances and leaching tests indicate that tannery sludge ash could be used as total replacement of CaCO3for waterproofing membranes. This work has to be intended as the first step of a study whose final goal is to find an effective, industrially applicable, way to improve recycling capabilities of tannery effluent treatment plant sludge in systems like roofing and waterproofing membranes thus solving an economical and environmental problem.

Treating Effluent

The requirements imposed on the Finnish forest products industry by the water authorities have focused on the reduction of BOD and suspended solids in the wastewaters. The industry has tried to comply with these requirements, first through internal measures such as process changes and closed systems. When these have not been sufficient, external treatment has been resorted to. The Wilh. Schauman Company in Jakobstad has chosen activated sludge with extended aeration from among the available methods for treating effluent. The plant has operated since the beginning of 1986 with extremely good results. In addition to the reduction of BOD and suspended solids, there has been a marked decrease of chlorinated phenols. Chlorinated substances with higher molecular weight are also removed during the process.

The present study evaluates the digestion of cork boiling wastewater (CBW) through a biochemical methane potential (BMP) test. BMP assays were carried out with a working volume of 600 mL at a constant mesophilic temperature (35 °C). The experiment bottles contained CBW and inoculum (digested sludge from a wastewater treatment plant (WWTP)), with a ratio of inoculum/substrate (Ino/CBW) of 1:1 and 2:1 on the basis of volatile solids (VSs); the codigestion with food waste (FW) had a ratio of 2/0.7:0.3 (Ino/CBW:FW) and the codigestion with cow manure (CM) had a ratio of 2/0.5:0.5 (Ino/CBW:CM). Biogas and methane production was proportional to the inoculum substrate ratio (ISR) used. BMP tests have proved to be valuable for inferring the adequacy of anaerobic digestion to treat wastewater from the cork industry. The results indicate that the biomethane potential of CBWs for Ino/CBW ratios 1:1 and 2:1 is very low compared to other organic substrates. For the codigestion tests, the test with the Ino/CBW:CM ratio of 2/0.7:0.3 showed better biomethane yields, being in the expected values. This demonstrated that it is possible to perform the anaerobic digestion (AD) of CBW using a cosubstrate to increase biogas production and biomethane and to improve the quality of the final digestate.

Industry Wastewater

Soft drinks industry wastewater from various production lines is discharged into the Industrial Effluent Treatment Plant. The traditional coagulation/flocculation method as first step, followed by biological treatment as second step, has been adopted for treating the soft drinks industry wastewaters. The performance of the plant has been evaluated. It has been found that the effluent characteristics are in most cases in correspondence with the requested standards for discharging the effluent into the Nicosia central sewerage system.
