Trant Engineering has subcontracted Veolia Water Technologies to design and build an AS5 Actiflo ® Carb high-rate clarification unit to treat raw water from the high metaldehyde ground water source. The main reason for selecting the AS5 Actiflo ® Carb process for this application is its ability to remove metaldehyde, turbidity and colour based on extensive Affinity Water and Veolia trials.
The average design criteria of the ACTIFLO ® unit is based on a 40 m 3 /h/m 2 of projected surface in the settling tank. This corresponds to a 2–2–6–3 design, which means 2 min detention time in the coagulation tank, 2 min in the flocculation tank, 6 min of maturation and finally 3 min in the settling tank.
ACTIFLO settling process The particular design pertaining to the coagulation, injection and maturation tanks, the dosage of microsand and a lamellar settling process all contribute in providing a high performance and reliable water treatment system. Water coagulation A coagulant is injected to the raw water upstream of the unit.
1. Mainly Actiflo setup footprint is very small and for reuse. The lighter density sludge is discharged from the compact when compared to conventional clarifier. top of the hydro-cyclone and sent to final disposal. 2. The design results in footprints that are 20times smaller than conventional clarification system.

Following soda ash and PAC dosing the water goes to the Actiflo mixing tank which contains a pH probe with optimal pH for coagulation being 7.1-7.2. There are high & low alarms on the floc pH monitor of 7.6 and 6.3. The water then goes to the Actiflo turbomix tank at which point a mix of microsand and 0.1% polyeletrolyte is added to aid ...
ACTIFLO® TURBO is equipped with: • a coagulation tank • a fl occulation tank with a TurbomixTM • a hydraulically optimized settling tank with lamella • a hydrocyclone for microsand recovery • a sludge thickening system / a contact tank when the unit operates with powdered activated carbon (Actifl o Carb) or as a softener (Acti Soft)
The flocculated water enters a settling tank where the particles settle to the bottom and a circular scraper rakes them into a sump in the center of the basin. From the sump, the material goes into hydrocyclones, which separate the sand from the solids or sludge. The sand recycles to the injection tank and the solids flow by gravity to lagoons.

thickener tank and new polymer batching and dosing plant for all of the thickener streams. Actiflo® process The Actiflo® process is a patented compact water clarification system that utilises microsand as a seed for floc formation. The microsand, known asActisand, provides surface area that enhances flocculation and acts as a ballast or weight.
This product range is based on the Actiflo process developed by Veolia that uses microsand and polymer in the floculation tank to increase settling velocity. Veolia has more than 20 years of design, commissioning and operational experience. Over 1,800 Actiflo units have been installed worlwide by Veolia, including more than 900 package plants.

A Hydro-cyclone is a static device to classify, separate or sort particles that applies centrifugal force to a flowing liquid mixture so as to stimulate the heavy ...
Mobile solutions use our Actiflo®, Hydrotech Discfilter™, reverse osmosis, ion exchange and multimedia filtration technologies, delivered through trailers, containers and skid-mounted systems. Mobile water treatment systems offer a cost-effective alternative to fixed plants across many industrial environments.
sludge and re-injected into the flocculation tank while the sludge is gravity fed to the hydrocyclone detention tank and then pumped to the plant's residuals treatment (gravity thickener) system. From the Actiflo© units, clarified water flows through two 900 mm diameter lines to two ozone contactors.
The Actiflo method is a compact physico-chemical water treatment method. The method has for many years been used in waterworks for the treatment of surface water to produce drinking water, but is now to an increasing extent being used for treating wastewater and combined sewer overflows (CSO). The method works as weighted settling combined with ...
ACTIFLO® HCS' principal feature is that it comes with a specific hydrocylone* and an external recirculation loop. After settling, the sludge/microsand mixture is pumped to the hydrocyclone where the microsand is thoroughly washed before being injected back into the flocculation tank.
Ballasted clarification for a very high rate and compact process Actiflo® is a compact process that operates with microsand (Actisand™) as a seed for floc formation. Actisand™ provides surface area that enhances flocculation and also acts as a ballast or weight to aid a rapid settlement. Actiflo® is recommended for: > surface water ...
