What is Nutrient Neutrality? Pollution caused by too many nutrients, particularly nitrogen and phosphorus, in our rivers and estuaries is a big problem for some locations. The nutrients of concern arise from fertilisers, untreated or partially treated sewage and water running off developments (to name a few sources). Natural England therefore has created the “National […]
Tesni Hyett is studying BioMedical Sciences at Cardiff University. She is the daughter of 3P Technik UK’s Director Glyn Hyett. During the summer break between her 2nd academic year and 3rd-year professional training year at Sapienza University of Rome, Italy, researching Oncology, Glyn asked Tesni to research 6PPD in Stormwater. Glyn had read some articles […]
How smart rainwater harvesting (with a water butt or large above-ground water tank) can play its part to slow the flow of stormwater and help prevent floods and in particular overflow from sewers. Floods are again making the news in the UK as Storm Ciara brought heavy rainfall to parts of the north and west […]
Anyone who trains regularly on an artificial turf field or 3G sports pitch (or indeed has a son or daughter who does) will recognise the black ant-sized speckles of plastic that follow the player from the field to the car and then into home. The pesky microplastics from artifical turf are notorious for getting flicked […]
A Hard SUDS stormwater treatment device to treat polluted stormwater runoff from roads, car parks, metal roofs, industrial sites and artificial sports pitches. Connectable surface area from 1600 to 3600m2 depending on the contamination level of the runoff. For installation in either concrete or plastic chambers within 1500mm shafts. Fully DIBt approved, and so meets […]
Chapter 26, the 2015 SuDS Manual (CIRIA publication C753, Ref 1) presents the Simple Index Approach (SIA) and Mitigation Indices for discharges to surface and groundwater (Tables 26.3 and 26.4). This useful Guidance provides for the adoption of SuDS Proprietary Treatment Devices (PTD), especially DiBT certified devices (Ref 2). Green Infrastructure SuDS components are rightly […]
The 3P HydroShark® Advanced Hydrodynamic Particle Separator removes suspended solids (SS or TSS) from the stormwater runoff within SUDS Treatment Trains. This patented and tested Proprietary Treatment Device protects surface water and groundwater infiltration systems. This Manufactured Treatment Device (MTD) device meets and exceeds all German stormwater treatment standards under DWA M153 D24 and D25. […]
The recent flooding in west Wales highlights the need for massive changes to the way we manage our river catchment areas. Attenuation ponds or reservoirs in the countryside are part of the solution to stormwater management and surface water runoff to avoid downstream flooding. Talking to the Tivyside newspaper, Dr Glyn Hyett emphasized the importance […]
Specialist rainwater filter for installation directly into the ground. Connectable surface area 100 to 175m2 depending on contamination level of the runoff. How it works The rainwater from the drained area is fed into the inlet, which is at the lower end of the shaft. Here, sedimentation of particles, especially the sand faction and above, […]
The Hydro Filter Channel Drains are a multi-process treatment unit for use in SuDS/WSUD systems treatment trains. It is able to both mechanically filter and then chemically bind pollutants like PAHs, hydrocarbons, heavy metals like Cd, Zn, Cu, Pb as well as phosphate and ammonium. The retained pollutants then can be disposed of easily, legally […]
