Water Framework Directive (WFD), 2000
• Requires all water bodies to achieve “good status”
UK Water Industry – Many sites have to meet more stringent TP consents
• AMP 6 – below TP 0.5 mg/l
• AMP 7 – below TP 0.25 mg/l
• AMP 8 – TP 0.1 mg/l proposed
Requirements for Technologies
• Guarantee TP consent
• Handle high solids loading due to chemical dosing
• Low Totex and small footprint
• Future proof if the consent is further tightened to 0.1 mg/l

FilterClear: High Effluent Quality
• Depth filtration (900 mm) with 4 layers of media
– High effluent quality
– High filtration rate (25 – 35 m/h)
– High solids holding capacity
– Prevents solids breakthrough and extends runtime
– Stratification after backwash
• No flocculation tank or polymer required
• Not introducing plastics or fibres
• Average operating pressure (0.4 to 0.5 bar)
• Enclosed filter, no moving parts, safe to operate
• Modular design and easy to scale up
