In wastewater ponds, bacteria numbers decrease considerably in the case of raised algae concentrations in the effluent. This shows that algae have a high potential for bacteria reduction in wastewater. Simultaneously, algae remove nutrients from the water for the formation of biomass. However, suspended algae also cause a high secondary pollution in the effluent of wastewater treatment plants. By using attached algae, as they are frequently observed as an algal biofilm in the effluent of wastewater treatment plants, the problem of separation of algae and water can be avoided. Furthermore, the algae can be removed simply from the water. In this study the possibilities for bacteria reduction and nutrient removal were examined with the aid of an algal biofilm. The results show that an algal biofilm process can be used for cases where small amounts of wastewater should be treated and a high quality of the effluent should be attained.

Edale lies in the valley of the River Noe about 3 miles north-west of Castleton. Near Edale End, about 2½ miles below the village, the Noe turns from a nearly east and west course to a nearly north and south course past Hope to join the River Derwent. In the neighbourhood of Edale the floor and lower flanks of the valley are formed of black shales known as the Edale Shales; they are overlain in succession by the Mam Tor Sandstones, the Shale Grit, the Grindslow Shales, and the coarse Kinder Scout Grits which form the great plateau of the Peak and the precipitous edge of Kinder Scout. North of the Edale valley the Mam Tor Sandstones reappear below the Shale Grit in Ashop Dale and Alport Dale. They occur also to the west of the valley in two narrow inliers just north of the railway in Roych Clough and Moor Clough.

Abstract Copper contamination of drinking water and marine areas is detrimental to human health and the environment. Physical and chemical approaches currently used for copper removal from water tend to be expensive and may introduce chemicals to the water. Using suspended algae to remove copper is a biological approach. Its cost is relatively low, and algae can be used for other purposes after being used for copper removal. However, this approach using algae is currently limited in its usefulness due to technological barriers. For example, chemical agents used to remove suspended algae from water after copper is absorbed, can cause secondary contamination. Using immobilized algae instead of suspended algae can overcome these problems. In this preliminary study, hydrogel filters containing algae cells and those containing no algae cells are printed on an extrusion-based 3D printer. They were used in a custom-build filtration setup for copper removal. Experimental results show that hydrogel filters containing algae cells reduced copper concentration in the test solution by about 83% (from 3 to 0.5 ppm) after one hour of filtration, while hydrogel filters containing no algae cells reduced copper concentration in the test solution by about 50% (from 3 to 1.5 ppm) after one hour of filtration.
