Pressure Sand & Activated Carbon Filters
First barrier
Raw & ETP water
SDI / TSS reduction
Backwashable
Ahura Aqua's high-performance media filters are the first barrier in every treatment train — removing fine particles, suspended solids, organic contamination, odour and colour from raw or ETP-treated water.
As the best pre-filtration ahead of UF, RO, EDI, UV and ion-exchange beds, they cut the pressure drop and fouling load that would otherwise cripple downstream membranes and resins.

Graded media bed — finer sand on top does the filtration, heavier sand / anthracite below supports it. Water hits an entry distributor that spreads it evenly across the bed.

Activated carbon media adsorbs dissolved organics, chlorine, colour and foul smell — and reduces oil & grease to a limited extent.

How It Works
01
Distribution
Feed strikes an entry distributor, splaying water evenly across the media for uniform flow.
02
Filtration
Suspended solids are retained in the fine media bed; heavier graded media supports the filtration layer.
03
Saturation
As load accumulates the bed chokes — either flow drops or TSS rises in the product line.
04
Backwash
A differential pressure gauge flags the moment; backwash flushes the retained solids and restores capacity.
