Reducing the solids content in your waste

03 June 2017

Food Processing finds out more about a solution that can help reduce solids content in effluent, which can help cut disposal costs. 

Meeting water discharge regulations is critical for industrial organisations – the more suspended solids in your effluent, the more you will need to pay for discharge and disposal.  

Hydro International has introduced a low-energy, small footprint rotating belt screen, the Hydro MicroScreen for the UK Food Processing sector. It has been designed to reduce suspended solids in wastewater by capturing residual material, rather than flushing it into the sewer system, helping operators to reduce water discharge costs with a solution that takes up just one-tenth of the footprint of multi-stage pre-treatment.

Energy is one of the biggest expenses in process water treatment with plants often using multiple step pre-treatment processes to reduce TSS, BOD and FOG before discharge. Hydro MicroScreen is said to offer energy savings of up to 50% when compared to primary clarification technologies.  

At a Kelloggs Cereal’s manufacturing facility in the United States, the technology has replaced an intended new multi-stage treatment system, saving the company £1.6M in constructions costs – less than half of the original budget and in half the footprint.  The plant treats 450 m3/hr of high strength wastewater from its cereal making operation and the Hydro MicroScreen removes solids consisting of sugars, rice, wheat, oats and oil and greases, saving 30% on the company’s surcharges.

An additional benefit is that it has reduced the residual liquids in the dewatered solids.  Previously, screened solids contained less than 10% solids which had to be manually moved in slop carts through the production area twice daily. Dewatered solids off the Hydro MicroScreen average 32% total solids significantly reducing the amount of material to be handled and making handling much easier. The material is now simply discharged to a skip and sold as animal feed along with other solid waste from the production line.

Hydro International will be operating a Hydro MicroScreen at its Ely site in July to demonstrate its screening capability.
