Evolution Aqua K+ Pressure Filter 4800- up to 4800 Gallons 

The Evolution Aqua K1 Micro Bead filtration systems are pressurized filter systems that deliver incredible levels of filtration for ponds. By using the new K1 Micro filter media instead of conventional beads, these filters offer better biological and mechanical filtration. This is due to the vast protected surface area of the K1 Micro media. The media also improves flow through the filter meaning you can use lower energy pumps.

Evolution Aqua have re-designed the K1 Micro Bead filters for 2021 to offer new and improved performance.

K1 Micro offers a whole range of benefits over beads including:

• improved biological filtration
• better mechanical filtration
• improved flow
• reduced back pressure on pumps
• increased protected surface area
• improved internal design
• re-designed internal pipework

K1 Micro Biological Media:
Rather than using conventional beads as its principle filter media, it uses K1 Micro media. This provides better biological and mechanical filtration, since the K1 media has a vast surface area of 950m2 per m3. This protected surface area safely houses beneficial bacteria and prevents them from being flushed to waste during the cleaning cycle. Only dead bacteria and waste debris will be discharged. This prevents ammonia and nitrite spikes after maintenance.

How the K1 Micro Bead Filter Works:
Water is pumped into the filter from the pond, through a multi-port valve where the internal pipework directs the water to the bottom of the unit. As the water flows upward, dirt and debris is trapped within the mass of K1 Micro filter media. The K1 Micro media (which provides a beneficial bacteria) delivers biological filtration. The filtered water flow back into the pipework at the top of the unit, through the multi-port valve and back down the return line into the pond. The filter is incredibly easy to clean, by simply moving the handle on the multi-port valve into the corresponding positions to perform a backwash and rinse of the K1 Micro media.

The K1 Micro Bead Filter is operated by a multi-port valve. This multi-port valve functions by pushing down on the handle, turning it and relocating it into one of the operating positions shown on the multi-port valve. The valve must always be operated with the circulating pump switched off. The ball valve positioned below the air blower must be closed when the pump is running. Below we offer an explanation of each of the multi-port valve’s functions:

• BACKWASH: This is the position the multi-port valve should be in for cleaning the K1 Micro filter media. With the valve in this position, water flow is reversed through the filter bed so that the water flow is directed to the top of the unit (B) and exits the unit at (D) and goes out to the waste line (E).
• RINSE: This is the position the multi-port valve should be in for agitating the K1 Micro filter media. With the valve in this position, air (supplied by the air blower) is used to agitate the filter media. Later on in the cleaning process, water is used to rinse the K1 Micro and exit to waste (E).
• WASTE: This is the position the multi-port valve should be in to allow water to by-pass the filter bed and drain to waste (E). With the multi-port valve in this position, the water flow is directed straight to waste by-passing the unit. This function can be used to lower the water level or for
• vacuuming your pond without soiling the filter.
• RE-CIRCULATE: This is the position the multi-port valve should be in to allow water to completely by-pass the filter. With the valve in this position, water is pumped from the pond to the multi-port valve and directly back to the pond, without flowing through the K1 Micro Bead Filter. This is particularly handy if you are treating your pond.
• CLOSED: This is the position the multi-port valve should be in for closing all flow to the filter. This position is not to be used with the pump running. Do not operate the multi-port valve with the circulating pump switched on. The ball valve must be closed when the circulating pump is running.
• FILTER: Incoming water from the pond enters the MPV at point (A). The water enters the vessel at point (D) then flows upwards through the K1 Micro filter media to the top exit bar (B). The filtered water is returned through the multi-port valve at point (C) and back into the pond.
