The package offers complete in-house design and specification service including a turnkey service of initial site survey, commissioning and project liaison if required. Suitable for larger applications and manufactured from glass reinforced plastic (), the system is installed below ground. Low running cost and maintenance The design has no internal mechanical moving parts therefore the plant requires minimal annual maintenance Emptying of the tank is also not required during maintenance of air distribution system Low installation costs and flexibility on site Only a small excavation is required due to its compact design allowing flexibility of positioning on site

Energy saving options and chemical dosing packages can be configured to the design for site specific requirements Does not impede views due to the below ground installationrsd blunt air cleaner Variable flows and loadsair purifier eligible hsa The unique design of the flow balancing in the primary tank means it can cope with variable flows and loadstherapure tower air purifier review Robust operation and stand-by facility Safe, clean, accessible air diffuser system with large access lids for easy maintenance Humus and primary sludge are stored in one place for simple tankering operation Tank 25 years life GRP is UV stabilised with an external gel coat finish which extends the asset life to 25 years

This houses the blower(s), a Form 2 control panel and air distribution manifold.

Included as standard is 10m of airline, to connect the blowers to the tank. Blower and airline upgrades are available if the kiosk is sited further than 10m from the plant. The Form 2 control panel, automatically controls the operation of the plant.  Form 4 is also available. Kiosks upgrades available on request e.g. walk in kiosk. MK2 lids for commercial application: All lids are lockable Large lids for easy access to each zone Assisted lifting with gas struts Fully serviceable due to easy access Easily removable air diffusers Optional safety grating when in place prevents risk of fall The HiPAF Treatment Process Primary– Primary settlement is in accordance with EN12255-4, giving the required hydraulic retention time and ensuring that 30% of the BOD will settle out in the primary tank.  WPL HiPAF plants below 500 persons will have sludge storage integral to the primary tank. The primary settlement tank is equipped with baffles to prevent floating scum entering the biological phase of the treatment process.

It also incorporates WPL Limited’s unique forward feed system which lowers the level in the tank, during periods of low flow, to provide a buffering capacity for possible surges in the. Biological– After primary settlement, the settled liquor flows to the biological treatment unit by displacement and via the air lift forward feed. The biozone is fully segmented internally to eliminate the risk of process short cuts. Each biozone segment is filled with high voidage plastic filter media, where both carbonaceous and nitrifying processes take place, mitigating process risks associated with variable loads. Air to oxygenate the influent and to scour excess biomass from the filter media is introduced continuously below each chamber by a series of diffusers. Final– Following biological treatment the effluent flows into the final (humus) settlement tank where the excess biomass settles out. The humus tank is equipped with air lifts which are arranged to automatically transfer settled humus sludge to the primary tank for co-settlement.
