Municipalities will spend $1.2 billion in 2015 for new centrifuges to dewater sewage sludge. This is the conclusion reached by the McIlvaine Company in Sedimentation & Centrifugation World Markets.
East Asia will be the regional leader with purchases in excess of $500 million. There are many new secondary treatment plants under construction in the region. Centrifuges are favored at the larger plants while belt filter presses are favored at the small plants.
NAFTA will be the second largest market. There are many planned upgrades of old plants in the U.S. Centrifuges are used for final dewatering, but they are also used for gravity thickening.
There is a substantial market in Eastern Europe. Romania has recently purchased centrifuges for three plants. Over 50 cities continue to discharge their untreated wastewater into rivers or the Black Sea. Around half of all existing wastewater treatment plants do not comply with EU requirements. It is intended that the EU standards will be implemented in all municipal wastewater treatment plants by the year 2018. This will require the expansion and modernization of existing plants, and the construction of new wastewater treatment plants.
