When granting Environmental Permission to an individual House Owner
Make sure the Polonite® filter is installed at a maximum distance from where a Crane Lorry can stay:
For 500kg filters not more than 10m
For 1000kg filters not more than 5m
Make sure to note in your AM system what kind of treatment plant that is installed at each property. This will greatly facilitate when it is time to replace the filter bag.
Make sure to share data between Environmental Office and Recycling organization.
Make sure the dimensioning of the Polonite filter is correct.
Making timely filter replacements happen
Filters shall be replaced timely; not too late (environment protection) and not to early (unsatisfactory resource utilization). Therefore, don’t specify replacement intervals defined in terms of calendar time. This has very little relevance. Instead, make sure house owners are reporting results of pH-readings and, if relevant, water analyses. We recommend that the first reading shall be taken after one full year of operation, and thereafter preferably every six months. Keep reported readings in your AM system. When a new reading is reported, perform a simple ‘parity check’ – the pH as well as the phosphorus retention is gradually reduced over time. If readings show significantly other development of results there might be reasons for investigating why.
Organize replacements as campaigns, preferably one in the fall and one in the late spring. A house owner that has not provided satisfactory readings will automatically be enrolled in the next campaign.
By organizing replacement campaigns, driving distances can be optimized. Which translates into a minimized environmental burden and a maximized cost efficiency to the benefit also of the house owner.
Taking care of saturated filters is legal obligation for the municipality, but if the capacity is not at hand, please don’t hesitate to seek assistance from Polonite Nordic AB.
Administrative and fees
The Polonite® filter concept provides excellent opportunities not only for a robust method to assure phosphorus is not disseminating into the environment, but also for enabling and effective phosphorus recycling. However, to provide house owners with a concept that is also financially attractive, it is important to handle filter replacements efficient. Therefore, always make sure you are, or your contracted partner is, in a position to offer the add-on service of offering a complete replacement cycle to the house owners.
Most contractors dealing with Polonite® filter replacements are rather small companies. Therefore, don’t make procurement processes more complicated than what is necessary. Always look at the big picture and avoid formal requirements that may easily disqualify the small, but smart, companies. Also consider the opportunities for ‘Direct Procurements’ etc that might be available. Please refer to Guide #19 from ‘Avfall Sverige’.
According to Swedish law ‘Kommunallagen’, all house owners within a municipality shall be charged the same fee for corresponding services, regardless of physical driving distances and the like. In line with the actual legal framework, also consider incentivizing the replacement charges to house owners on grounds of a superior environmental and recycling concept.
Elaborate viable solutions for utilizing saturated filters. These consist of lime-material with a couple of percent of phosphorus.
Depending on volumes, the following alternatives might be considered:
Use saturated filter media as a soil enhancer when producing plant soil.
Find major farmers that are interested to spread directly on farmlands (please request our guide on how to calculate a suitable fertilizer give).
Make an agreement with one of the ‘fertilizer recycling companies’ (like BioTotal AB) that is entering the market.
