FILTRATION

AUTOMATIC VALVELESS GRAVITY FILTERS

Sureflo’s flagship AVGF is a “fit & forget” media filter that backwashes itself on head-loss alone — no pumps, no valves, no controllers, no operator. Over 100 units are installed across India, USA, Africa, Myanmar and Nepal.

  • Three chambers: filter bed, filtrate collection & backwash storage
  • Flow range 10–500 m³/hr per stand-alone unit; twin-bed for higher flow
  • No electricity, no moving parts, near-zero maintenance
  • Ideal for cooling-tower side-stream filtration to raise Cycle of Concentration

OTHER RANGE OF FILTERS

Beyond AVGF, Sureflo builds automatic backwash filters, pressure sand filters, iron-removal filters and raw/sea-water filters for desalination pre-treatment — ranging from 20 m³/hr up to 8,250 m³/hr and beyond.

  • Side-stream filtration (SSF) for recirculating cooling water
  • Automatic backwash — no manpower, no backwash pumps or flow controllers
  • Iron-removal filters for high dissolved-iron feed water
  • Sea-water pre-filters for desalination plants

SEPARATION

DECANTER CENTRIFUGES

Sureflo’s 2-phase and 3-phase decanter centrifuges deliver continuous solid–liquid separation for sludge dewatering, slop-oil recovery and effluent treatment. Every unit ships with a VFD and Basic Core Controller (BCC) for efficient, automated operation.

  • 2-phase & 3-phase configurations (W-series)
  • Variable frequency drive (VFD) as standard
  • Basic Core Controller for full automated control
  • Low installed power reduces running cost

SEPARATION

MULTI-SCREW PRESS

A low-speed, low-energy alternative for sludge dewatering. The multi-screw press handles oily and fibrous sludges gently, with minimal wash-water and quiet, clog-resistant operation.

  • Low-speed operation — low energy, low noise
  • Self-cleaning screw & ring design resists clogging
  • Compact footprint for retrofit into existing plants

AERATION

DIFFUSED AERATION SYSTEMS

Fine and coarse bubble diffusers – in both disc and tube formats – engineered for high oxygen-transfer efficiency in municipal sewage and industrial effluent treatment. Available as retrievable systems that lift out for servicing without draining the tank.

  • Fine bubble diffusers (disc & tube) for high transfer efficiency
  • Coarse bubble diffusers (disc & tube) for mixing duty
  • Retrievable diffused aeration plants for STP/ETP
  • Complete aeration plant design & installation

TREATMENT PLANT

PLANTS

ETP & ZLD PLANTS

Turnkey effluent treatment and zero-liquid-discharge plants that combine Sureflo’s own filtration, separation and aeration building blocks. We produce high-quality water from any source, recycle wastewater and recover precious materials from waste liquid.

  • Complete design, build & commissioning
  • Recycling of leachates and industrial effluents
  • Resource & material recovery from waste streams
  • Integrates Sureflo filtration, separation & aeration
