At a water reclamation plant in Palmetto, on the outskirts of Columbia, USA, several thousand cubic metres of sludge is purified and sorted into containers every year. Previously, the containers had to be constantly alternated as they became full, causing undesirable and inefficient downtime. In order to achieve a more efficient system, the water reclamation plant ordered a specially constructed rotating conveyor from Hydria Water. The reason for the client’s requirement for a rotating conveyor was that it should be able to deposit material in several containers placed in a row, without the need to empty or move the containers.
– The solution that we came up with is a 12-metre-long rotating conveyor that can be remotely controlled. The client is delighted and now has a much better and more efficient process, Henrik Karlgren, Senior Product Manager at Hydria Water, says.
When a district heating plant in Sweden experienced problems with microplastics in the water, they turned to Hydria Water for a solution. Hydria Water recommended a stormwater overflow treatment system and installed a testing facility to evaluate its efficacy.
– We assembled a testing facility with a stormwater screen that has now been in operation for eight weeks. We have performed several tests, and the results exceeded the client’s expectations, Henrik Karlgren, Senior Product Manager at Hydria Water, says.
A 60 micron wire mesh that catches very small particles in the water was used in the tests, and there was a marked difference between the filtered water and the unfiltered water, with a reduction of more than 90% in microplastic particles larger than 60 microns.
– The test was a resounding success. The machine filters out all of the unwanted materials that we want it to – and even more, actually, the project manager at the district heating plant says.
At the moment, work is ongoing on expanding the stormwater overflow treatment system to full scale, similar to the stormwater overflow treatment facility that Hydria Water installed at the Hammargårds water reclamation plant in Kungsbacka, Sweden.
