Veolia Water Technologies says the firm’s organic coagulant has helped to optimize the Effluent Treatment Plant (ETP) at a large pet food production facility in the Northwest. By switching to Hydrex 62930, the facility is estimated to make cost savings of more than £65K p/a on chemicals for ETP, Veolia says, combined with reduced chemical handling and a safer product with low the danger.
The ETP at the production facility relies on a Dissolved Air Flotation (DAF) unit to process the site’s effluent. The treated water goes through a biological process before being released into the local river. Until recently, a combination of Poly Aluminum Chloride (PAC) with caustic soda as a pH corrector was used in the DAF unit, to process the effluent and remove suspended solids from the cooking processes.
Brian Jones, Business Development Manager at Veolia Water Technologies approached the site and conducted jar testing using the company’s alternative organic coagulant Hydrex 62930.
The results were very encouraging and Brian advised the customer to continue using Hydrex 62930 organic plant-based coagulant to replace PAC and caustic soda. Current chemistry is becoming increasingly expensive due to supply issues and rising energy prices.
Alternatively, Hydrex 62930 may provide efficient coagulation with a smaller dose rate compared to PAC. This means it will reduce the plant’s annual coagulant consumption by 87% along with reduced sludge disposal and caustic soda usage.
Thanks to the optimized chemistry of Hydrex 62930, pH correction is also not required. Thus, additional chemical savings are made and the need to transport and handle hazardous chemicals around the site is reduced.
Furthermore, thanks to the improved flocculation provided by Hydrex 62930, Veolia Water Technologies was able to ensure continuous operation of the DAF unit despite the customer’s expansion plans. As a result, the optimized DAF unit can handle a larger volume of water generated by the expansion than before. Simple switching to chemistry also means that the unit does not need to be replaced to keep up with potential future demand.
A representative of the pet food manufacturer commented: “Brian was great to work with and was able to assure us at every stage of the process that the new chemical solutions could provide the benefits we needed without the hassle in further follow-up. I would definitely recommend Veolia Water Technologies for its products and its team.”
