Sludge is a by-product, produced during the treatment of wastewater. Pathogens, organic matters, chemicals, and microorganisms are different constituents of the sludge. Besides, sludge also contains harmful agents, such as heavy metals, that adversely affect the environment and cause severe health issues when directly exposed.
The global sludge treatment chemicals market is projected to reach US$ 11.4 billion by the end of 2027, in terms of revenue, growing at CAGR of 4.7% during the forecast period (2019 to 2027).
Therefore, sludge is to be treated before disposing into the environment. The chemicals used at different stages of this treatment are termed as sludge treatment chemicals. Industries such as food and beverage, personal care, automotive and paper and pulp are the key consumers of these chemicals due to the large production of sludge while manufacturing.
The primary reasons driving the growth of the global sludge treatment chemicals market are expanding industrialization, rising environmental concerns, and an increasing requirement for sludge removal around the world. Furthermore, the increased emphasis of various regulatory authorities on reducing sludge volume is likely to boost market growth during the forecast period. However, constraints such as the high cost of the sludge treatment procedure, as well as advancements in the water treatment process to reduce discharged sludge, have impeded market expansion.
The sludge treatment chemicals market is divided into types such as coagulants, flocculants, disinfectants, and others. Coagulants accounted for more than half of the market in 2015 and are likely to maintain their lead throughout the forecast period. Coagulants are utilised in the removal of solids, the clarity of water, the softening of lime, the thickening of sludge, and the dewatering of solids. Coagulant cost effectiveness would present a potential opportunity for the sludge treatment chemicals market.
