Polymer Preparation & Chemical Dosing
Whether your aim is to reduce suspended solids, control odour, pH adjustment or precipitate elements from your wastewater, our chemical dosing units (CDUs) will allow you to manage your wastewater.
Hydrotec’s state-of-the-art monitoring equipment provides the control system with the information required to determine the exact chemical dosing required. This critical step allows for increased efficacy towards your aim for the wastewater whilst also helping to avoid incorrect dosing, in turn saving your company money.
Coagulation and Flocculation:
CDUs play a crucial role in the coagulation process within wastewater treatment, enhancing the removal of suspended solids. The precise addition of coagulants, such as ferric chloride and polymers, into the treatment system encourages the agglomeration of particles. The larger flocs that are created are more easily separated from the wastewater, particularly at subsequent treatment stages.
pH Correction and Odour Control:
Whether required to meet discharge consents or to adjust acidity or alkalinity for optimal treatment, our CDUs are capable of effective pH adjustment. Sodium hydroxide and sulphuric acid are used to treat low and high pH, respectively. Where nuisance odours are concerned, hydrogen peroxide is a powerful oxidant, often used to neutralise hydrogen sulphide and other odorous compounds.
