New research has been published looking at enhancing microplastic removal from natural water using coagulant aids. Highlights Larger microbeads (1 mm – >250 μm) have >95 % removal; smaller ones (10 – <250 μm) are challenging. Denser microbeads like PVC (1.38 g/cm³) settle better than lighter ones like PE (0.97 g/cm³). PAC (0.4 mmol/L) with 3 mg/L PAM at pH 8 removes […]

An external filter, retrofitted to your washing machine, is an immediate way of stopping microfibres going down the drain. Guardian lifestyle piece You might not know it, but installing a washing machine filter might be one of the simplest defences against microplastics entering the ocean. Scientists estimate there are 14m tonnes of microplastic on the ocean floor, and a […]

Microplastics in sewage: a toxic combination that is poisoning our land By George Monbiot Policy failure and lack of enforcement have left Britain’s waterways and farmland vulnerable to ‘forever chemicals’ We have recently woken up to a disgusting issue. Rather than investing properly in new sewage treatment works, water companies in the UK – since […]

A new study in the journal Chemosphere studies the effects of polystyrene beads on three freshwater species. The study expands the knowledge on the acute, chronic, and subchronic effects of MP polystyrene beads (PS-MP, size 1.0 µm) on three species of the freshwater chain. These species are the green alga Raphidocelis subcapitata, the rotifer Brachionus calyciflorus, the cladoceran crustacean Ceriodaphnia […]

New study estimates there is at least ten times more plastic in the Atlantic than previously thought Posted: 19 August 2020 NOC ‘The mass of ‘invisible’ microplastics found in the upper waters of the Atlantic Ocean is approximately 12–21 million tonnes, according to research published in the journal Nature Communications. Significantly, this figure is only for three […]

One way to remove microplastics from water is to encourage them to clump together into compounds that can be filtered – or, in the context of the 20-year-old Irish inventor Fionn Ferreira’s work, magnetized – out. Ferreira created a homemade ferrofluid – a magnetic mixture of oil and powdered rust – and successfully used it […]
