Mud from Chisinau treatment station can be used as fertilizer

The mud taken from the Chisinau Wastewater Treatment Station to the first store in 2012 may be used as organic fertilizer for agricultural crops and for the soil, Info-Prim Neo reports, quoting a communiqué from SA Apa-Canal Chisinau. The water supplier announced that it finished a mud processing cycle and started to use the second store for keeping mud. Depending on the volume and concentration of the impurities in wastewater, the mud will be stored for 4-5 years. Simultaneously, the mud kept in the first store in 2009-2010 will be subject to composting and pathogen microflora destruction. If the agricultural sector, farmers and private individuals asked for considerable volumes of organic-mineral fertilizer of a high quality, leaves, straw and other organic matter would be added in the mud processing process. It would be crumbled and packed so that the sale of this product becomes a reality, says the administration of Apa-Canal Chisinau. According to the company, an important economic impediment in the process of transporting the fertilizer is the long distance that it must cover as there are few arable fields near the treatment station where the mud could be widely used. A possibility is to use a part of the mud collected at the station to recultivate and lay out the quarters, ditches and precipices around Chisinau, as it was done in Russia’s Sochi. The preliminary report of the feasibility study “Water Supply and Wastewater Treatment in Chisinau Municipality Program” made by the company SEURECA and financed with a grant given to SA Apa-Canal Chisinau by the EU, which is to be completed in the first half of next year, contains methods for processing and using the mud accumulated at the Chisinau Wastewater Treatment Station.
