Veolia Water Applied sciences says the agency’s natural coagulant has helped to optimise the Effluent Remedy Plant (ETP) at a big scale pet meals manufacturing facility within the Northwest. By switching to Hydrex 62930 the ability is estimated to make a price saving of over £65K p/a on chemical substances for the ETP, says Veolia, mixed with decreased chemical dealing with and a safer low-hazard product.
The ETP at manufacturing facility depends on a Dissolved Air Flotation (DAF) unit to course of the location’s effluent. The handled water then goes by a organic course of earlier than discharge to the native river. Till not too long ago, a mix of Poly Aluminium Chloride (PAC) with caustic soda as a pH corrector had been used with the DAF unit, to course of the effluent and take away the suspended solids from the cooking processes.
Brian Jones, Enterprise Improvement Supervisor at Veolia Water Applied sciences approached the location and carried out jar testing utilizing the corporate’s various natural coagulant Hydrex 62930.
The outcomes have been very encouraging and Brian suggested the client on the continued use of Hydrex 62930 natural plant-based coagulant to interchange the PAC and caustic soda. The present chemistry was turning into more and more costly as a consequence of provide points and vitality worth rises.
Alternatively, the Hydrex 62930 might present glorious coagulation with a smaller dose charge in comparison with PAC. This meant it might cut back the plant’s annual consumption of coagulant by 87% together with decreased sludge disposal volumes and caustic soda utilization.
Because of the optimised chemistry of Hydrex 62930, pH correction was additionally not required. Thus, making additional chemical financial savings and decreasing the necessity to transport and deal with hazardous chemical substances across the web site.
Moreover, because of the improved flocculation offered by Hydrex 62930, Veolia Water Applied sciences was in a position to make sure the continued performance of the DAF unit regardless of the client’s growth plans. Because of this, the optimised DAF unit will be capable to deal with better volumes of water generated by the growth than it will have beforehand. The straightforward swap in chemistry has additionally meant that the unit doesn’t should be changed with the intention to sustain with potential future demand.
A consultant of the pet meals producer commented: “Brian was nice to work with and was in a position to reassure us at each stage of the method that the brand new chemical options might present the advantages we would have liked with out the trouble of the additional monitoring. I might positively suggest Veolia Water Applied sciences for its merchandise and its staff.”
